RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010INTRODUCTIONThe “Riga City Sustainable Energy Action Plan for 2010–2020” (hereinafter – the ActionPlan) was approved on 6 July 2010 by decision No. 1644 of the Riga City Council. TheAction Plan was drafted because Riga was the first European capital to sign the“COVENANT OF MAYORS” on 30 September 2008; and drafting of the Action Plan andannual progress reports on implementation of the Action Plan complies with the provisionsset out in the “COVENANT OF MAYORS”.The objective of the Action Plan is to achieve the target of “20-20-20” by 2020. It meansthat the city commits itself to reduce CO2 emissions by at least 20 % by 2020 improvingenergy efficiency by 20 % and ensuring that renewable energy sources account for 20 % inthe energy mix.The structure of the Progress Report is broadly in line with that of the Action Plan, and thereport provides an opinion on the current situation in implementation of the Action Plan bycomplying with the tasks of the Action Plan and the selected criteria for assessment of theimplementation of the Action Plan. The progress report provides a general insight into thesituation over the period of 2006–2010 and more detailed information on the situation in2009 and 2010. The results are compared against the baseline year chosen in the ActionPlan (1990).The first progress report was drafted within the framework of the international INTERREGIVA project “Covenant of Mayors in the Central Baltic Capitals” (COMBAT) (PVS ID2621).The Progress Report of the “Riga City Sustainable Energy Action Plan for 2010–2020” onimplementation of the Action Plan in 2010 has been drafted under the guidance of the Rigamunicipal agency “Riga Energy Agency” (REA) in cooperation with the Institute ofPhysical Energetics (IPE) and involving the management structures of the Riga CityCouncil established for implementation of the Action Plan in 2010.The progress report on implementation of the Action Plan in 2010 has been drafted underthe editorship of the Director of REA, Dr.sc.ing. Maija Rubīna.3


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20101. RESULTS OF CO₂ EMISSION REDUCTION IN 20101.1 Methodology for calculation of CO₂ emissionsAs the basis for calculation of the volume of carbon dioxide (CO 2 ) emissions for thereference year, the consumption of all types of energy and fuel in the territory of Riga cityin the given year is taken irrespective of the location where the energy is produced. CO 2emissions are calculated separately from the power consumption, heat consumption in thedistrict heating system, fuel consumption in the transport sector, and energy end-use inhouseholds, industry, state and municipal institutions and the services sector. Only CO 2emissions are calculated from the total set of greenhouse gas emissions. The standardmethodology and parameters based on the guidelines drafted by the IntergovernmentalPanel on Climate Change (hereinafter – IPCC) are used to calculate the emissions.The algorithm for calculation of CO 2 emissions in Riga city:Figure 1.1. Source: IPE report.The energy consumption beyond the control and powers of the local government, forexample, consumption by maritime and rail transport, all types of cargo transit, aviationservices, use of agricultural and construction machinery, is not taken into account incalculation of the CO 2 emissions. Also, emissions from industrial installations, refrigeratorsand air conditioning systems, natural processes of putrefaction of organic matter, wastewater treatment reservoirs and storage sites for solid household waste, as well as openburning processes are not taken into account.Emission factors based on the average values of physical properties of fuels applied inLatvia and methodology prepared by the IPCC are used in calculation of CO 2 emissions 1 .An emission factor 2 describing the average structure of electricity generation in Latvia isused to calculate CO 2 from power consumption, because electricity in Riga is provided byvarious electricity generation sources including cogeneration units utilising gas as a fueland hydropower plants.1 “Methodology for calculation of CO2 emissions from stationary combustion of fuel and industrialprocesses”, the Latvian Environment, Geology and Meteorology Agency, 2009.2 Technical Annex to the ong>SEAPong> template instructions document: The emission factors.4


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010In order to calculate CO 2 from the heat consumption in the district heating system, theemission factor is used, and it is calculated on the basis of the heat production structure andfuel structure in the respective year.The algorithm for calculation of the CO 2 emission factor for heat production in the districtheating system:Figure 1.2. Source: IPE report.To calculate the CO 2 emission factor of the district heating in Riga city for the respectiveyear, first of all, the emission factor of heat production by the production sources of AS“Rīgas siltums” is calculated depending on the fuel structure used and volume of heatproduced in the given year. Secondly, the emission factor of heat production bycogeneration plants of AS “Latvenergo” is calculated depending on the fuel structure usedand volume of heat produced in the respective year. Thirdly, the weighted average emissionfactor of heat production for the Riga district heating system is calculated by taking intoaccount the share of the volume of heat produced by each of the said companies.In order to calculate greenhouse gas (GHG) emissions from transport in Riga, the overalltraffic flow is divided into three large groups:• cars registered in Riga;• public transport vehicles (buses, taxi buses and taxis);• cars entering Riga.The number of cars registered in Riga is obtained from the data on the number of cars inLatvia collected by the Road Traffic Safety Directorate (CSDD). The calculation ofemissions takes into account only the number of cars in good running order. Theinformation source for identification of the number of public transport vehicles is theinformation collected by the CSDD and data from the Transport Department of Riga CityCouncil. The number of cars entering Riga is identified by analysing the number of cars ingood running order and registered in the Riga region and data on the incoming andoutgoing traffic flow in Riga.In addition to the above-mentioned division of traffic flow, it was also divided by the typeof the fuel used (petrol, diesel and liquefied petroleum gas (LPG)) and by the followingtransport groups:• cars;• light trucks (< 3.5 t);• trucks (> 3.5 t);• buses;5


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010• motorcycles and mopeds.The COPERT IV model widely used by the EU Member States is applied to calculate theemissions from road transport. In this case, the model was adapted for calculation ofemissions in Riga city.1.2 Data for emission calculationsInformation on the total heat consumption in the district heating system of Riga and inbreakdown by separate consumer groups was received from the main heating operator inRiga city – AS “Rīgas siltums”. Information from AS “Latvenergo” was used as the basisfor identifying power consumption and its breakdown by consumer groups. Theinformation provided by AS “Latvijas gāze” was used to assess the structure of energy enduse,as well as the structure of energy production in Riga.In order to assess the energy end-use in the industrial and service sector, and national andmunicipal institutions in Riga, the database “No. 2 – Air – Survey on protection of air”available on the home page of the Latvian Environment, Geology and Meteorology Centrewas used. The said survey comprises publicly available information on the annual volumeof fuel used for heat and/or power generation, and technological processes both atterritorial and organisational level. Forms of this report are filled in by companies orinstitutions (operators) which have a valid authorisation for performance of Category A orB polluting activities or declaration of a Category C polluting activity and which complywith the polluting activity stipulated in Annex 1 of the Regulation (EC) No. 166/2006 ofthe European Parliament and of the Council of 18 January 2006 concerning theestablishment of a European Pollutant Release and Transfer Register, and emit pollutantsprovided for in the Annex 2. These provisions mean that all heat production sources withconsiderable heat load of > 0.2 MW are included in this statistical survey. Therefore thesaid statistical survey comprises most of the fuel users of Latvia.The survey is available since 1997. When conducting the analysis, each of the operatorswas individually assessed and depending on the specific nature of its activities it wasgranted one of the following statuses – an industrial company included in the sub-group“Emission Trading Scheme (ETS) company”, company of the commercial and servicesector or municipal and public sector institution. The number of the analysed fuel end-usercompanies is provided in the table below showing also the number and structure of theanalysed emission operators.The ETS sector is singled out separately in the analysis of fuel consumption since 2005.The information on the end-use of fuel by companies in the ETS sector is obtained byindividually collecting and analysing the documentation of these companies in the ETSsector – the reports on CO 2 emissions in 2005 and 2008 available on the home page of theLatvian Environment, Geology and Meteorology Centre within the system of the Registerof Greenhouse Gas Emission Units.In order to assess the energy end-use in the household sector, the data on the structure ofenergy consumption, number of consumers and household characteristics obtained from thesurvey “Consumption of Energy Resources in Households” (respectively, for 1996, 2001and 2005) carried out by the Central Statistical Bureau (CSB) of the Republic of Latviawere used. This survey separately provides the information on the structure of energyconsumption in Riga city. The sampling for the survey is made as a stratified one-stage ortwo-stage random sampling of households.6


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20101.3 Results of emission calculations for Riga city in the period 1990–2010Within the framework of the previous study CO 2 emissions for 1990, 1995, 2000,2005 and 2008 were calculated by using the described methodology for calculation ofemissions and available information about the consumption of energy and fuel in Rigacity. In this report, emissions for 2005 and 2008 are adjusted, and emissions for 2010are calculated. Adjustment of the emissions for the said years was related to updating ofthe energy end-use based on a detailed analysis of the data base “No. 2 – Air – Surveyon protection of air” and discovery of several systematic errors in this data base.Total CO 2 emissions in Riga in breakdown by types of consumption for 1990 –2010, in thousands of tonnes of CO 2 equivalents:Figure 1.3. Source: IPE report.By analysing total CO 2 emissions in Riga city in 2010 and their evolutiontendencies in comparison to 2008, the following aspects can be identified:• the total volume of emissions has decreased by 6 % compared to 2008. Themain reason for it is the major reduction of emissions in the transport sector by13 percentage points;• in 2010, most of emissions come from the transport sector (35 %) and heatconsumption in the district heating system (31 %), while the rest is generatedby fuel consumption in different consumer sectors (18 %) and powerconsumption (15 %);• in 2010, the volume of emissions has increased only for the use of fuel indifferent consumer sectors (by 4 percentage points).7


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010The calculated CO 2 emissions in breakdown by sectors, in thousands of t CO 2 equivalents:Table 1.1.Emission source 2000 2005 2008 2010Transport 552 732 861 747Fuel consumption 446 394 369 384Power consumption 229 311 345 325Centralised heat 753 669 655 649consumption consideringclimate adjustmentsTotal CO 2 emissions 1982 2107 2229 2105To analyse the changes in emissions, indicators describing changes in the volume ofemissions per applicable unit can also be used. One of such indicators is the emissions perone resident of the city (tonnes of CO 2 per capita). According to the Figure 1.4. CO 2emissions per capita have decreased by 4.2 percentage points in 2010 compared to 2008.CO 2 emissions per capita in Riga, in tonnes of CO 2 equivalents per capita:Figure 1.4. Source: IPE report.1.4 Impact assessment of the CO 2 emission reduction measuresTo assess the impact of the CO 2 emission reduction measures as envisaged in the ActionPlan in 2010, two methods were used. The first method is the bottom-up assessmentmethod determining the volume of emission reduction on the basis of the calculated ormeasured volume of energy replaced or saved through specific measures and by using acorresponding emission factor in respect to energy or fuel. Generally, emission savings arecalculated in the following way:EM saved = E * EF, where8


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010EM saved – the volume of CO 2 emission savings in the reference year, in tonnes of CO 2 peryear;E – the volume of energy or fuel replaced or saved by using renewable energy sources(RES) per year, MWh;EF – the emission factor for the respective type of energy or fuel, in tonnes of CO 2 /MWh.The second method is the top-down assessment method determining the volume ofemission reduction by using changes in selected indicators describing energy consumptionand emissions in a specific period and the data on energy consumption.Within the reporting period, the following measures have been implemented in respect tothe district heating system:• production of additional heat by installation of an absorption-type heat pump in thecogeneration unit of HP “Imanta”;• use of biomass in the form of wood-chips for energy production at AS “Rīgassiltums”.The top-down method was used for the impact assessment of the above implementedmeasures. The capacity of emissions from the heat energy supplied by the district heatingsystem is described by the indicator “CO 2 t/MWh th ”. Based on the changes in thisindicator, the volume of emissions saved in 2010 was calculated according to the followingformula:EM CSA EM2008EM2010saved = ( )* E2010, whereE E2008CSA2010CSAEM CSA saved – CO 2 emissions saved in the district heating supply system, in tonnes of CO 2per year;EM 2008 CSA ; EM 2010 CSA – volume of emissions in the district heating supply system inrespective years;E 2008 , E 2010 – volume of energy supplied in the district heating system in respective years.The calculated CO 2 emission savings from the measures implemented in respect to thedistrict heating supply system amount to 6792 tonnes of CO 2 per year.Impact assessment of implemented CO 2 reduction measures:Table 1.2.Measure implementedAdditional heat production by installing anabsorption-type heat pump in the cogeneration unitof the HP “Imanta” and use of biomass for energyproduction at AS “Rīgas siltums”Renovation of municipal educationalestablishments by reducing heat consumptionRenovation of multi-apartment houses by reducingAssessed reduction ofemissions in 2010, intonnes of CO 267922161747heat consumptionUse of biofuel in road transport 19419Total 291199


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010For the impact assessment of other implemented measures shown in Table 1.2, the bottomupassessment method was used, and it was based on the volume of energy saved inbuildings and amount of fossil fuels replaced in road transport.Impact assessment of CO 2 emission reduction measures in 2010:Figure 1.5. Source: IPE report.The assessment shows that the impact of the first implemented measures has resulted inreducing the volume of CO 2 emissions in Riga city by almost 1 percentage point in 2010compared to the “business as usual” scenario where no measures would be implemented.The assessed emission savings amount to almost 28 % out of the emission savingsprojected in the minimal scenario of the Action Plan for 2020.10

MEASURES FOR REDUCTION OF ENERGY CONSUMPTIONAND IMPROVEMENT OF ENERGY EFFICIENCY2.1 Production and transmission of energy2.1.1 HeatingThe district heating ensures 76 % of the total heat consumption in Riga. 77 % of thesupplied heat is used for heating of residential houses and for hot water production. In thefiscal year 2009/2010, AS “Rīgas siltums” produced about 30 % of heat at its heat plantsand boiler houses, while approximately 70 % were purchased – 98.26 % from Riga TECplants of AS “Latvenergo”, namely, TEC-1 and TEC-2, and 1.74 % from SIA “Juglasjauda”. The volume of heat supplied to consumers in breakdown by fiscal years:Figure 2.1. Source: Annual report for 2010 by AS “Rīgas siltums”.Heat losses and the proportion of heat losses in the heating network:Figure 2.2. Source: Annual report for 2010 by AS “Rīgas siltums”.During the reporting period, Riga experienced changing climate conditions and a changingduration of the heating period described by the following data:11

Source: Annual report for 2010 by AS “Rīgas siltums”.Disconnection of objects may be caused by various reasons, including cases when aconsumer chooses an alternative type of heating (for example, in the heating season of2009/2010 – 23 objects with the total heat load of 12.8 MW were disconnected); renovationof buildings, in which case the connection will be re-established after the completion ofworks (in 2009/2010 – 2 objects with the heat load of 0.3 MW were disconnected); vacantspaces, where no heating is needed (in 2009/2010 – 22 objects with the heat load of 3.9MW were disconnected); and cases of continuing debts (in 2009/2010 – 5 objects with theheat load of 1.4 MW were disconnected). 28 new objects have been connected in theheating season of 2009/2010. Decrease in new heat load connections in 2009/2010 isrelated to the national economic crisis and stagnation of construction works. However, thesituation is starting to improve since 2011.The reduction in heat losses of heating networks is ensured by purposeful repairs andreconstruction thereof. Modern heat isolation materials and industrially isolated pipes theheat stability of which is not affected by the high level of groundwater inherent to Riga arebeing used. In 2009/2010, the length of direct-buried heating networks in Riga had reachedalready 191.3 km or 28 % of the total length of heating networks owned by AS “Rīgassiltums”. The total length of heating networks in the city is 890 km, and 75 % of them areowned by AS “Rīgas siltums”.12

Source: Annual report for 2010 by AS “Rīgas siltums”.In Riga, more than 90 % of the total heat consumption in the district heating system areproduced by using a highly efficient mode of cogeneration. Measures for improvement ofenergy efficiency are being actively introduced to the heat production process at the heatsources of AS “Rīgas siltums”, including:Table 2.2.Measure1.

Thefirst round of modernisation has been completed in TEC-2 – a modern power unitwith the capacity of 420 MW has been installed replacing the obsolete and technicallyoutdated unit and significantly increasing the energy efficiency of the powergeneration process. Implementation of the second round of modernisation is inprogress – another modern, high-capacity power unit is being installed and will be putinto operation in 2013.Figure 2.6.

The structureand thus, the technical features of such boilers differ substantially from the standardboiler models. The condensation-type units also allow efficiently utilising heat usuallyflowing out together with flue gases. By reducing the flue gas temperature and thuscondensation of steam in them, additional heat is acquired, which is diverted to theheating system. By using this technology and burning the natural gas, the efficiencyrate of the boiler increases by 11 %, thus reducing the annual consumption of naturalgas and emissions as well. The actual annual consumption of natural gas of multiapartmentresidential buildings where the district heating supply is ensured by using20


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010hot water has substantially decreased, since in many locations the stoves utilisingnatural gas are being replaced with electrical units.2.1.4 Fuel consumption in Riga city in 2010Energy end-use in Riga cityIn order to assess the end-use consumption of energy in the industrial and servicesector of Riga, the database “No. 2 – Air – Survey on protection of air” available onthe home page of the Latvian Environment, Geology and Meteorology Centre wasused. Since 2005, the companies involved in the Emission Trading Scheme (ETSsector) are singled out separately in the analysis of fuel consumption. The informationon the end-use of fuel of companies in the ETS sector is obtained by individuallycollecting and analysing the documentation of these companies in the ETS sector –the reports on CO 2 emissions in 2005, 2008 and 2010 available on the home page ofthe Latvian Environment, Geology and Meteorology Centre within the system of theRegister of Greenhouse Gas Emission Units.In 2010, natural gas was the principal type of fossil fuels in Riga city. It represents72.5 % of the total end-use consumption of energy. The second most important fuel inbreakdown by the consumption volume is biomass forming almost 22 % of the totalenergy consumption. In 2010, the share of natural gas consumption increased by 5percentage points compared to 2005. The consumption of oil products (heavy fuel oiland diesel fuel) is insignificant in Riga, for it amounts to only 1 % of the total end-useconsumption of energy. The share of oil product consumption has decreased by 5percentage points compared to 2005. It has to be noted that the extent of using biogashas increased in terms of absolute values, and its share in total consumption hasgrown from 1.5 % (2005) to 2.6 %. The share of renewable energy sources in the totalend-use consumption of energy in 2010 in Riga city was 24.5 % .Figure 2.13. Structure of the end-use energy consumption in breakdown by types of fuel in Riga city,TJIn 2010, the largest share (51 %) of end-use energy was consumed by the industrialcompanies of the ETS sector, while the industrial companies outside the ETS sectorconsumed 21.8 %, companies of service sector – 19.2 % and municipal and state21


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010institutions – 8 %. The small share of the total end-use energy consumed by municipaland state institutions can be mainly explained by the fact that most of therepresentatives of this consumer group are connected to the district heating system.Figure 2.14. Structure of the end-use energy consumption in breakdown by consumer groups inRiga city, TJNatural gas consumptionNumber of companies and organisations utilising natural gas according to thedatabase “Air-2”:Table 2.5.2005 2008 2010ETS industry 9 10 9non-ETS industry 84 74 78municipal and state 25 25 30institutionsservice sector 91 112 123Ten companies took part in the ETS system in 2005, but in the period 2008–2012twelve companies have been participating in this system. In 2005, the ETS systemincluded three companies; however, they are not participating in the next ETS period(2008–2012). In 2010, Būvmateriāli AN was the only company within the ETS systemnot utilising natural gas.Total natural gas consumption of ETS companies had increased in 2010 comparedto both 2005 (by approx. 55 %) and 2008 (accordingly by approx. 24 %). A moredetailed analysis of natural gas consumption by companies in the ETS sector showsthat the largest share of consumption – accordingly 66 % in 2008 and 84 % in 2010 –is formed by two companies. However, the natural gas consumption of other22


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010companies in the ETS has overall decreased by approx. 6.4 million m 3 in 2010compared to 2008.Within the small scale (non-ETS) industrial sector, the natural gas consumption haddecreased in 2010 compared to both 2005 (by approx. 38 %) and 2008 (by approx.16 %).In the sector of state and municipal institutions, a small increase in natural gasconsumption occurred in 2010 compared to 2005 and 2008. In 2010, the natural gasconsumption increased by approx. 0.76 million m 3 (or by approx. 6.7 %) compared to2008, but about 50 % of this increase was formed by the consumption related to theinclusion of new organisations in the database.The natural gas consumption in the service sector is relatively stable. In comparisonto 2008, consumption increased by 1.4 million m 3 (or by approx. 6.5 %) in 2010.Twenty-seven new companies were included in the database “Air-2” in 2009/2010,but in 2008 the database comprised 17 companies, which did not submit reports in2009 and 2010.Consumption of liquefied petroleum gasAccording to the database “Air-2”, only few companies utilise liquefied petroleumgas. In 2005, there were 3 such companies, in 2008 – also 3 companies, but in 2010 –2 companies. With such a small number of companies utilising liquefied petroleumgas, no conclusions can be drawn about common development trends, because theconsumption is determined by individual choices of specific companies to use this oranother type of fuel and the availability of other fuel types.Consumption of heavy fuel oil and diesel fuelOverall, the consumption of heavy fuel oil and diesel fuel has been decreasing. In2010, the consumption of heavy fuel oil and diesel fuel was only almost 17 %compared to 2005. However, various trends can be observed in different sectors whencomparing 2010 and 2008. There has been an increase in consumption and a smallincrease in the number of liquid fuel users in the non-ETS industrial sector comparedto 2008. Yet there has been a small decrease in consumption and in the number ofusers in the service sector. Usually, utilisation of oil products is replaced by theconsumption of natural gas.Coal consumptionCoal consumption possesses specific features. It is determined by the choice ofindividual companies/organisations and also affected by the availability of other fueltypes. The total number of coal users is small. The largest share of coal is consumedby the public sector of Riga city, which included only 2 consumers in the period2008–2010: Šķirotava Prison and the Central Road Transport Base of the State Policeunder the Ministry of Interior of the Republic of Latvia; coal consumption hasincreased in both companies.In the service sector, coal consumption is more considerable – 136 tonnes wereconsumed (by 5 consumers) in 2010. Coal consumption in the service sector haddecreased in 2010 compared to both 2005 and 2008. However, with such a smallnumber of consumers, no conclusions can be drawn regarding consistent consumptiontrends.23


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010Wood pulp consumptionIn the ETS industrial sector, wood pulp fuel consumption increased in 2010compared to both 2005 (by approx. 64 %) and 2008 (by approx. 38 %). In 2005, woodpulp fuel was utilised by two consumers in the ETS sector (factories of AS LatvijasFinieris – Furnieris and Lignums), whose consumption had decreased in 2010 and2008 compared to 2005. Therefore, in comparison to 2005 increase in consumption ofwood pulp fuel in the ETS sector in 2008 and 2010 was determined by the newcomerto the ETS system in the period 2008–2012 – Bolderāja Ltd.Small (non-ETS) industry. The database “Air-2” shows a very significant decrease inconsumption of wood pulp fuel. In 2005, the database “Air-2” included 8 companies –wood pulp consumers with an annual consumption of more than 1,000 tonnes each –which do not appear in the database in later years. This explains the rapid decrease inconsumption of wood pulp fuel in 2008 compared to 2005.One of the largest consumers of wood pulp fuel in the service sector is SIA WTTerminal. Without this company, consumption of wood pulp fuel in the service sectorin the period 2005–2010 had remained practically the same. However, the choice ofSIA WT Terminal to use wood pellets (approx. 4.7 thousand tonnes) in 2010significantly increased utilisation of this fuel type.Utilisation of biogasThe biogas obtained in the waste water treatment process (utilising natural gas as theback-up fuel) is used by SIA Rigens operating at the waste water treatment plant“Daugavgrīva”, and heat energy for heating and provision of electric power for thesystem operator is produced in the process of cogeneration. The biogas consumptionof this company was approx. 90 TJ in 2008 and approx. 118 TJ in 2010.Motor fuel consumption by the transport sector in Riga cityIn order to calculate greenhouse gas (GHG) emissions from transport in Riga basedon motor fuel consumption in the city, the overall traffic flow is divided in three largegroups:• cars registered in Riga;• public transport vehicles (buses, taxi buses and taxis);• cars entering Riga.The number of cars registered in Riga is obtained from the data on the number of carsin Latvia collected by the Road Traffic Safety Directorate (CSDD). It has to be notedthat when assessing the fuel consumption, only the number of cars in good runningorder is taken into account. The information source for identification of the number ofpublic transport vehicles is the information collected by CSDD and data from theTransport Department of Riga City Council. The number of cars entering Riga isidentified by analysing the number of cars in good running order and registered in theRiga region and data on the incoming and outgoing traffic flow in Riga.24

RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010Figure 2.16. Source: IPE report.It has been assessed that motor fuel consumption by the transport in Riga citydecreased in 2010 by approximately 11 percentage points compared to 2008. Thedecrease in petrol consumption was most rapid (20 %), whereas gas consumptionremained at the same level as in 2008. Consumption of bioethanol and biodiesel hasincreased due to the implementation of laws and regulations on the mandatory shareof biofuel blended into motor fuel. In 2010, consumption of petrol amounted to41.6 %, diesel fuel – to 51.5 %, but biofuel – to 2.6 % out of the total motor fuelconsumption by the transport in Riga city.The main reason for the overall reduction in motor fuel consumption was thedecreasing intensity of using private road transport in 2009 and 2010, which wasaffected by the decrease in residents' income and increase in motor fuel prices in thereporting period.26

REA has created a database and carries out monitoring of energyconsumption in renovated houses for at least five years after completion of renovationworks.Actual data on specific energy consumption during the heating season (October–April) of 2010/2011 at the average outdoor temperature in Riga (-0.4) °C with theheating season lasting 192 days:kWh/m2200.0180.0160.0140.0120.0100.080.060.040.020.00.0Kurzemes prosp. 14Bebru 4Ozolciema 46/3Figure 2.17.Anniņmuižas bulv. 60Lielupes 1/9Rigondas gatve 7Kurzemes prosp. 4Celmu 5Patversmes 24Mārcienas 3Dzelzavas 84Terēzes 8Dzelzavas 97Lielvārdes iela 103Lielvārdes iela 101D.Brantkalna iela 7Palmu 6Tomsona 24Lielvārdes iela 105S.Eizenšteina iela 49Ieriķu iela 44According to this figure the dominant specific energy consumption for heating (atrelatively low outdoor temperatures during this heating season) ranges from 45kWh/m² to 80 kWh/m², which in general corresponds to the recommendationsincluded in the Action Plan. For the multi-apartment houses exceeding the abovenumbers residents had chosen incomplete complex renovation (no heat insulation forroofs, no renovation of the heating system or any other measures). Instead ofinsulating, the house on Ieriķu Street 44 was painted with reflecting paint, which afterthe analysis of results over several years proved to be the wrong choice made byresidents. The use of reflecting paint for such purposes is not allowed anymore inLatvia.Seven multi-apartment buildings renovated in 2010 with the co-funding (50–60 %)from the Structural Funds:Table 2.6.Address of the residential houseTotal area ofapartmentsaccordingto the heat supplierdataRenovation time27

The REA's Energy Efficiency InformationCentre has organised 8 expert roundtable discussion club seminars related to issuesconcerning the quality of renovation works, including technical solutions forinsulation of buildings' enclosing structures, renovation of the internal heating system,technical solutions for insulation of flat roofs, renovation of balconies and loggias,technical solutions for replacement of windows, solutions for ventilation of rooms,funding possibilities for renovation of multi-apartment buildings and experience inrenovation of multi-apartment buildings. REA experts have prepared 3 articlesincluded in specialised publications on building renovation, participated in interviewspublished in mass media, in radio broadcasts, specialised TV programmes, etc.REA keeps track of the process of renovation in multi-apartment buildings, takesphotos of buildings before and during different stages of renovation. Data on heatconsumption are collected and analysed in breakdown by years. To assure the qualityof renovation works, thermal imaging of all 21 buildings was done during the winterof 2010. On the basis of collected and obtained data, a brochure is being prepared,which will provide residents with the data on the experience of completed renovationworks. The brochure is to be issued in 2011.29

RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010As it can be seen in the thermal image of the facade, the insulation of facades andmaking of glassed-in loggias have been very effective.During the works, ten out of the twenty one renovated multi-apartment buildings havebeen equipped with allocators on the heaters in apartments, and also with temperatureregulators, which allows to record and adjust energy consumption in each apartment.According to the data analysis, when comparing heat consumption of these buildingswith the consumption of similar insulated buildings without allocators and regulators,the difference of consumption reaches up to 15–20 %. REA has launched a campaignfor installation of allocators by organising an expert roundtable discussions clubseminar focused on this issue at the beginning of 2011 and by issuing a thematicelectronic newsletter “REA vēstnesis Nr. 14” devoted to this topic. After assessmentof the above possibilities for improvement of energy efficiency, the Riga City Councilin cooperation with SIA “Rīgas pilsētbūvnieks” is preparing for implementation aproposal on equipping 5 multi-apartment buildings built within the last decade andowned by the local government (SIA “Rīgas pilsētbūvnieks”) with allocators andtemperature regulators. It is to be implemented in 2011.In 2010, the Housing and Environment Department of the Riga City Council prepareddocumentation for insulation of 2 social housings owned by the local government (onRēznas Street 10/2 and Gobas Street 20/1) – energy audits and a technical project, andin 2011 renovation of these houses was commenced, 75 % of the costs being coveredby funding from the ERDF.The materials related to renovation of multi-apartment buildings are available on theREA's home page www.rea.riga.lv under the section “Energy Efficiency”. A newsection of the home page, “Tips” was developed in 2010, and it contains best practiceexamples for implementation of renovation works.In order to facilitate the best practice in the area of buildings' energy efficiency, theMinistry of Economics of the Republic of Latvia, the Ministry of EnvironmentalProtection and Regional Development of the Republic of Latvia and the magazine“Latvijas būvniecība” announced the contest “The Most Energy Efficient Building inLatvia 2010”. Two buildings in Riga were placed second in the group of renovatedmulti-apartment buildings – on Kurzemes prospekts 14 and Bebru Street 4, and theperson who was authorised by apartment owners to organise the renovation wasValentīna Jermaka. Also, the building on Rigondas gatve 7, in Riga receivedacknowledgment for the achieved savings in heat energy consumption (authorisedperson – Īrisa Simanoviča).31

Within the framework of this project, modern light-emitting diode(LED) technologies were used as much as possible;• lighting in the territories of Riga pre-school educational establishments andsports grounds with the total capacity of 85 kW (44 sites in total);• decorative lighting of Riga city secondary schools and lighting of the newlyconstructed Juglas Street, Dikļu Street and other sites of lesser importance.The total actual growth of capacity related to development of the city's infrastructure,construction of new lighting systems and the resulting increase in the number of totallighting sites since 2008 is 200 kW, and the total capacity of the city's lighting systemin Riga was 7.0 MW in 2010.At the same time, it must be noted that a remote control system with the possibility tolower the voltage has been introduced as an experiment in cooperation with the RigaTechnical University and lamp manufacturing company “Philips”. The abovementioned electronic control units have been incorporated in lamps, thus replacing theout-of-date control throttles and start-up units. Voltage adjustment allows to directlyreduce the bulb's lighting level during night time when the traffic intensity is low, thussaving power.The new system has been installed on the existing lighting power line on AkadēmiķaMstislava Keldiša Street. Overall, 19 lamps with 150W high-pressure sodium bulbshave been equipped with electronic control units. The total installed capacity of thelighting line is 2.85 kW. Measurements of the load before and after installation of thecontrol system prove that depending on the length of dark hours of the day it ispossible to save up to 30 % of electric power this way.To completely and timely keep in track with the development of perspective LEDlamps, Akadēmiķa Mstislava Keldiša Street has been provided with the installationpossibilities for the said lamps. Such solution allows to compare the emitted light fluxof the new-technology LED lamps with the emitted light flux of high-pressure sodiumbulbs in standard lamps, and also allows the suppliers representing LED lampmanufacturers to assure themselves of the achieved results.In the nearest future, replacement of 70W high-pressure sodium bulbs with 36Wlight-emitting diodes is envisaged for lamps installed on the pillars made according tothe model “Senatne” along channels. The specific capacity economy of the aboveobject is intended to be 15 kW, which is not large in numerical terms, but isconsidered to be essential contribution to the feasibility study and prospective use ofLED lamps.2.2.4 City public transportIn 2009 and 2010, the city public transportation fleet was supplemented with thefollowing new vehicles:37

RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010The number of renovated buildings (public and multi-apartment buildings) which visually do notdiffer from newly constructed buildings (70 of them are municipal buildings referred to in theAction Plan) has substantially grown in the city. Preparation works have been carried out to startthe renovation of separate buildings the energy level of which is close to that of zero-energybuildings in 2011.The territorial plan of Riga City 2006–2018 stipulates the car parking policy promoting evenlybalanced development of city neighbourhoods by establishing a mutually balanced system of twotypes of parking lots:• city parking lots of city importance;• parking lots near sites of public importance.The objective of establishing a parking lot system is the following:- to relieve the central part of the city from road transport by increasing the efficiency ofpublic transport services;- to reduce the number of cars parked on the streets and thus the flow of vehicleslooking for parking places;- to save petrol and improve the environmental quality.Figure 2.43.45


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20103. USE OF RENEWABLE ENERGY SOURCESGeneration of biogas and its usage in the cogeneration process at the waste water treatment plant“Daugavgrīva” and at the solid waste landfill SIA “Getliņi” (outside Riga) continued during thereference period.Also, partial supply of electric power from the Daugava hydropower plant cascade – RigaHydroelectric Power Plant – continued in order to satisfy the city's needs.During the reference period, utilisation of biomass or wood-chips for heat generation at AS “Rīgassiltums” was actively increased by replacing natural gas with biomass at the heat plant“Vecmīlgrāvis”. At the end of the year, two biofuel water heating boilers with the total capacity of14 MW were installed at this heat source. Thus, in 2010, its volume including the use of biomassat the heat plant “Daugavgrīva” reached 30.922 loose-m³, which replaced 2,443 m³ of natural gasand reduced CO2 emissions by 4.591 tonnes. Construction of a cogeneration unit at the heat plant“Ziepniekkalns” also utilising biomass has been started.Table 3.1.Measure1. Use of wood biomass for energyproduction at AS “Rīgas siltums”, theamount of fuel per yearEnvisagedin theAction PlanTable4.3,page 94ActualimplementationtimeResponsibleforimplementation2010 AS “Rīgassiltums”Achievedresults30,992 loosem³In the private sector, heat pumps (mainly air heat pumps) were introduced for heating of houseswithin the borders of the city, but so far no inventory of these units has been made. In the fall of2010, the ground heat pump system with thermoprobes installed by deep drilling was put intooperation at the Riga pre-school educational establishment “Kastanītis” (Stērstu Street 19) and itreplaced the coal-fired boiler house operating until then. See Section 2.2.2 for description and data.To facilitate preparation for utilisation of geothermal energy in Riga, during the reference periodthe Riga municipal agency “Riga Energy Agency” promoted the dissemination of informationconcerning the potential volumes of hot dry rock energy in Latvia and Riga trough theinternational internet networks by giving presentations on this subject during workshops, organisedthe establishment of the Latvian National Geothermal Association (LNGA) by joining togetherexperts and stakeholders, participated with its presentations in the congress “GeoPower Europe2010” in Paris, which provided good contacts with foreign experts, and organised the firstinternational geothermal conference in Riga together with AS “Rīgas siltums” and LNGA, aswell as ensured sharing of experience with experts from Hungary and Norway (Oslo).So far separate collectors and batteries have been installed for utilisation of solar power in theprivate sector, but no inventory of these units has been made.In addition, separate studies including rough estimates have been drafted for possible installationof powerful heat pumps to utilise the heat from the treated waste waters for treatment units at theHP “Daugavgrīva” and to utilise the heat coming from the cooling flows at Riga TEC-1 and RigaTEC-2.46


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20104. AID MEASURES FOR IMPLEMENTATION OF THE ACTION PLAN4.1 Organisational measures4.1.1 Establishment of management structures for implementation of the Action PlanAs it is envisaged in the Action Plan, to ensure its implementation the local government hasestablished the following management structures:1) Implementation of the Action Plan is to be organised and supervised by the Riga municipalagency “Riga Energy Agency” (Paragraph 1 of the Decision No. 2204 adopted by the RigaCity Council on 11 September 2010) which has also drafted the Action Plan.2) Community-based implementation of the Action Plan is supervised by the Action PlanImplementation Management Board consisting of 11 members appointed by the Riga CityCouncil (Paragraphs 4, 5 and 6 of the Decision No. 2204 adopted by the Riga City Councilon 11 September 2010). The Management Board is chaired by the member of the Riga CityCouncil, Chairman of the Housing and Environment Committee. It consists ofrepresentatives of different groups of society – a member of the City Council,representatives of public administration institutions, energy consumers, and energysuppliers, companies providing energy-related services, scientists and universities. TheManagement Board reviews and approves the annual progress reports on implementation ofthe Action Plan. Since 2007, the Management Board in its current composition inter aliahas been successfully working in order to supervise the REA operations within theframework of the international project related to the establishment of REA, which wascompleted at the beginning of 2011.3) A community based Action Plan Steering Group consisting of 14 members (DecisionNo. 2853 adopted by the Riga City Council on 29 March 2011) has been established forcoordination of institutions related to implementation of the Action Plan; it is headed by theDirector of REA and is composed from representatives of the key institutions related toimplementation of the Action Plan. Members of the Steering Group provide the directinitiators of the Action Plan with the necessary feedback.4) As an advisory institution for REA facilitating fulfilment of its tasks and improvement ofits work, the community based Riga City Council Board of Consultative Experts onEnergy Supply Issues (REEKP) consisting of 16 members (Order No. REA-11-5-rsadopted by REA on 4 February 2011) has been approved; it is headed by an academic fromthe Latvian Academy of Sciences and is composed of the leading scientists and experts inthe sectors of energy and housing in Latvia. The REEKP successfully operates as a part ofthe Riga's local government since 2002.REA has concluded cooperation agreements with a number of nongovernmental organisations,including the Latvia's District Heating Association (LDHA), Baltic Environmental Forum (BEF),Latvian Energy Efficiency Association (LATEA), and Coalition for Gender Equality in Latvia,International Exhibition Company “BT 1”, Children’s Forum of Latvia, company hosting theportal “Building.lv” – “1.Sabiedrība”, and others. These agreements envisage cooperation inorganising joint events related to implementation of the Action Plan, distribution of informationand its placement in online portals, etc.47


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20104.1.2 Involvement of the society in implementation of the Action PlanIn 2010, REA continued to ensure and maintain long-term cooperation with different interestgroups represented by societies and associations of residents and professionals, and other unitingorganisations, operations of which are related to supporting and implementing measures in areas ofenergy supply, energy efficiency and renewable energy sources. These include not only the abovementioned NGOs which REA has concluded cooperation agreements with, but also many otherpublic organisations, for example, the Zero emission mobility support society (BIMAB), LatvianApartment Owners Association, Cooperation Network of Latvian Non-governmentalOrganisations of Women, Latvian Chamber of Commerce and Industry, Latvian NationalGeothermal Association, Geological Society of Latvia, Latvian Heat Pump Association, SolarEnergy Association, Renewable Energy Confederation, Employers’ Confederation of Latvia,Latvian Water and Gas Consumer Association, Latvia Building Engineers Union, LatvianAssociation of Local and Regional Governments, and others. These organisations are involved ininformation exchange, consultations, joint work groups, events and workshops.Raising awareness of unorganised groups of residents and their involvement is ensured in everyway possible both directly and by using information technologies (IT).REA directly ensures consultations for interested persons visiting the office of REA, but for nowit cannot provide consultative events for a wider audience in its office (36m² including 4workplaces and 5 employees) due to lack of space at the REA Energy Efficiency InformationCentre. In 2010, premises were granted for this purpose (26 m²), and currently they are undergoingrepairs, which gives hope that the new information centre will be opened for all residents in 2011during the Riga Energy Days. Also, communication via e-mail and telephone is used forconsultations. The intensity of direct consultations is equal to 3 to 5 consultations a day onaverage.As regards information technologies, the key measure is maintenance and improvement of theREA home page www.rea.riga.lv. In 2010, this home page was visited by 9,684 interested persons.The home page entirely reflects the actions of REA, and the section “News” includes descriptionsof all major activities (115 articles in 2010) supplemented with photo materials and presentationsof events. To respond to the interests of the home page's visitors, a new section “Tips” containingmainly information useful for house insulation was developed in 2010. The information placed onthe REA's home page is often republished on web sites of cooperation partners or otherorganisations.REA publishes on a regular basis (quarterly) a specialized electronic newsletter “REA vēstnesis”.The newsletter mainly informs about innovative technologies and materials coming to Latvia. It isprepared in cooperation with companies and professional associations. In 2010, four issues of thenewsletter were published (No. 9–No. 12). REA also prepared and distributed a small number ofprinted versions of the newsletter (less than 50).When addressing residents on issues regarding energy efficiency, it is very important to useinformation leaflets published by REA on its website and other specialised portals, as well asdistributed in hundreds of printed copies at gathering places for residents – in waiting rooms,during seminars and specialised exhibitions, etc. In 2010, the following information leaflets wereprepared and distributed in addition:1) No. 4 (edited) – “How to draft an application for house renovation in 2010?”;2) No. 5 – “Heat pumps with thermoprobes installed by deep drilling in the Rigaeducational establishment Kastanītis in 2010” (in Russian);3) No. 6 – “Innovative form of heating – a heat pump with thermoprobes installed bydeep drilling in the Riga educational establishment Kastanītis”.48


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010At the same time, also the following information leaflets prepared by the Investment andDevelopment Agency of Latvia (LIDA) are distributed:4) “Improvement of heat insulation of multi-apartment residential buildings”;5) “Мероприятия по улучшению теплоустойчивости многоквартирных жилыхдомов” – the same leaflet in Russian.One of the topical measures by which REA addresses the representatives of residents is the eventof expert roundtable discussions organised by the Energy Efficiency Information Centre (8 eventsin 2010) with the number of participants varying from 40 to 120, and the topics include thefollowing:1) Funding possibilities for renovation of multi-apartment residential buildings;2) Technical solutions for renovation of balconies and loggias of buildings in terms ofimproving the heat insulation;3) Renovation progress of multi-apartment residential buildings in Riga in 2010;4) Technical solutions for ventilation systems in multi-apartment residential buildings interms of energy efficient renovation of buildings;5) Heat insulation for building facades according to the Guidelines for EuropeanTechnical Approval;6) Finishing of building facades in terms of energy efficient renovation;7) Financial advantages of energy efficient renovation of buildings;8) Measuring and regulating the energy consumption in a multi-apartment building.Discussion materials and presentations have been published in a special section on the REA'shome page, and the topics are directly related to implementation of the Action Plan.An efficient model for cooperation with the general public isorganisation of thematic campaigns. In 2010, REA andother organisations signed a Memorandum ofUnderstanding with the Ministry of Economics onorganisation of a joint energy efficiency campaign under theslogan “Live warmer” to support the renovation of multiapartmenthouses. Within the framework of this campaign,two seminars organised together with the Ministry tookplace in the meeting room of the Riga City Council in 2010on topics such as regulations concerning preparation ofmulti-apartment houses for renovation and the progress ofrenovation, as well as other events were organisedincluding regular special seminars organised by the Ministry in cooperation with experts from theRiga Technical University and dedicated to the quality issues of renovation works. All events arebroadly reflected in online portals. Seminars taking place in the meeting room of the Riga CityCouncil are broadcasted online, and their videorecordings are saved and publicly available.In October 2009 and 2010, Riga Energy Days were organised lasting for a whole month. The mainevent during Energy Days is the 4-day international exhibition “Environment and Energy” in theĶīpsala exhibition hall in Riga with more than 100 local and foreign companies taking part in thisexhibition and 20–27 thousand interested persons visiting each year. REA participates in thisexhibition with its own stand and organises the key seminars on issues of energy efficiency andrenewable energy sources. Visitors include officials from local governments and the respective lineministries of Latvia and other Baltic states, entrepreneurs and experts, representatives ofnongovernmental organisations and public organisations, and private persons. This exhibitionfacilitates introduction to new technologies and equipment and also ensures the necessaryconsultations, as well as deals are concluded for implementation of respective measures during thisexhibition. The programme of Riga Energy Days comprises a wide range of events, includingconferences and seminars, forums, roundtable discussions, local thematic exhibitions, etc. Within49


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 2010the framework of Energy Days, REA cooperates with foreign embassies to attract foreign expertsand companies to the events of Energy Days dealing with innovative topics. In 2009, the maincooperation was formed with the embassy of Sweden, thus supporting participation of Swedishexperts in seminars with presentations on issues of passive house construction and experience inusing solar collectors. The Riga Energy Days of 2010 began in the meeting hall of the Riga CityCouncil by conducting a seminar on experience in construction of wooden buildings in Austriaorganised in cooperation with the embassy of Austria and by opening in the lobby of the Riga CityCouncil a local exhibition on this topic which could be visited for several weeks. A similar eventin cooperation with the embassy of Canada on the topic of energy efficiency in construction ofbuildings will be held in 2011.Figure 4.1. Opening of the exhibition“Environment and Energy 2010”Figure 4.2. REA stand in the exhibition“Environment and Energy 2010REA together with its cooperation partners has prepared the following brochures on examples ofbest practice for distribution:1) “Use of heat pumps for heating of buildings” (31 pages). Target audience – experts andemployees of local governments;2) “Possibilities of using heat pumps for heating of buildings under urban conditions” (12pages). Target audience – residents;3) “Improving energy efficiency of the existing buildings”;4) “Heating and ventilation”;5) “Rational utilisation of energy in everyday life”;6) “Utilisation of renewable energy sources for heating of buildings”;7) “Principles of energy efficient planning”.Electronic versions of brochures are available on the home page of REA.Also the following DVD videos have been prepared:1) On examples of best practice in energy saving with 13 episodes (each 2–3 minutes inlength) shot in different European countries:- “Energy passports” (Hamburg, Germany);- “Cycling is good for you!” (Munster, Germany);- “Public transport” (Prague, the Czech Republic);- “Washing and drying machines” (Bratislava, Slovakia);- “Solar panels” (Dzierzgoń, Poland);- “Passive house” (Vilnius, Lithuania);50

Riga has used these resources to solve problems of the city in the sector of sustainableenergy development. This work was actively commenced in 2007 by establishing the Rigamunicipal agency “Riga Energy Agency” (REA) with aid from the programme “Intelligent Energy– Europe”. Currently, REA is the leading and coordinating institution in the city that ensuresimplementation of the Action Plan.The state aid for implementation of the Action Plan is mainly provided in the form of managingthe absorption of EU Structural Funds (the Ministry of Economics) and governance of the flexiblemechanisms of the Kyoto Protocol in Latvia (the Ministry of Environmental Protection andRegional Development). Riga city actively participates in these processes.The “Law on renewable energy” has been drafted and submitted to the Saeima for revision.Also, the “2nd National Action Plan on Energy Efficiency of the Republic of Latvia 2011–2014”has been drafted, and its planned measures are well linked with the Action Plan of Riga city whichis also supplemented as an appendix to the national Action Plan.According to the measures planned within the framework of the Action Plan for 2010, the draftbinding regulations “On the Procedure by which the Local Government of Riga City shall ProvideAssistance in Implementation of Energy Efficiency Measures in Residential Buildings” have beenprepared by the local government of Riga city. The binding regulations envisage the followingpossibilities for the local government:1) to provide support in the form of co-investment amounting to 80 % from its budget forperformance of energy audits of multi-apartment houses;2) to include in the respective financial aid provided to the apartment owners who receive aidfrom the local government for payment of utilities the monthly expenses related to the heatinsulation of a building.The draft binding regulations are undergoing the process of approval.The local government of Riga also deals with the issues of establishing a revolving fund andpreparation of direct energy-related services for renovation of buildings.It successfully implements renovation of public buildings, mainly educational establishments inRiga, by channelling considerable financial resources into investments during recent years.51


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 20104.2 Attracted financial instruments and amountsTo facilitate development and implementation of the Action Plan of Riga city, REA workedtogether with cooperation partners on the following international projects in 2010:1) Project of 2006 of the European Union (hereinafter – EU) programme IntelligentEnergy - Europe: “Creation of Energy Management Agencies in the BORDEAUX Agglomeration(France), City of LATINA (Italy), City of MURCIA (Spain), City of PORTO (Portugal) and Cityof RIGA (Latvia)” (PVS ID 1734). Project Manager – the local government of Bordeaux. Theproject was completed in February 2011. The Riga municipal agency “Riga Energy Agency”(REA) established within the framework of this project has taken over the operational experiencefrom energy agencies of other European countries (there are approximately 400 such agenciesoperating in local governments of Europe) and acts as the key support provider for the localgovernment in dealing with issues related to energy supply, energy efficiency and renewableenergy sources within the local government's territory. REA has certain domestic and internationalreputation, and to fulfil its functions, it cooperates with municipal administration institutions of theEuropean Union, state and other local governments, embassies, companies and professionalassociations, as well as nongovernmental organisations and mass media. REA participates in thenetwork of EU energy agencies ManagEnergy and in other EU measures resulting from thespecific nature of the agency's operations.2) International project “From Estonia till Croatia: Intelligent Energy Saving Measures forMunicipal Housing in Central and Eastern European Countries” (INTENSE) (PVS ID 2418).Project Manager – the Baltic Environmental Forum (BEF); the project is funded by the EUprogramme Intelligent Energy- Europe. The project's duration is 3 years, and it is to be completedin September 2011. 12 countries and 28 organisations participate in this project. Within theframework of this project, the information on legal documents of Latvia concerning the issues ofbuilding renovation has been collected, as well as proposals for improvement of these legaldocuments have been drafted and submitted to the Ministry of Economics and Ministry ofEnvironment. While participating in the project, essential information on experience inconstruction of “passive” (low energy consumption) houses and the renovation process inGermany has been obtained, a series of articles has been prepared for the specialised journal“Pārvaldnieks” and the information has been distributed through other channels including theREA's home page. Also, brochures and a film have been prepared. The key objective of thisproject is to transfer the experience and knowledge from Western countries and implement them inLatvia.3) Implementation of the international project “Introducing Heat Pumps for Heat Supply inRiga City: Setting-up a Demonstration Object” (PVS ID 2162) funded by the bilateral NorwegianFinancial Mechanism. It is an investment project (total costs: LVL 166,8 thousand including theNorwegian funding – 77.9 %). Project Manager and submitter – REA. The Property Department ofthe Riga City Council has been assigned as the responsible institution for organisation ofrenovation works on site under the order by the Chairman of the Riga City Council. Thecooperation partner in this project is the Baltic Environmental Forum, which provided theinformative part of the project. The project was completed in April 2011. Within the framework ofthis project, buildings of the Riga pre-school educational establishment “Kastanītis” have beenrenovated: the coal-fired boiler has been dismantled, a heat pump complex for heating of buildingshas been installed, 10 deep-drillings have been made in the depth of 120 m and thermoprobes havebeen installed in them. The project was completed by analysing the data of the first heating seasonand drafting the recommendations for installation of such heating systems. Inter alia, three52

Head of theConsortium – the German Association for Housing, Urban and Spatial Development. Thesubmitter of this project on behalf of Latvia is SIA “Rīgas pilsētbūvnieks”, but REA is thecooperation partner. The project is to be completed at the beginning of 2012. The project activitiescarried out in Riga are focused on the neighbourhood of Jugla based on which proposals related tooptimisation of the renovation process of multi-apartment buildings, improvement of theinfrastructure and urban environment are drafted. Within the framework of the project, theinformation and materials have been examined, and proposals for establishment of a municipalenergy service company (MESCO) to organise the renovation of multi-apartment buildings in thecity and proposals for establishment of a municipal revolving fund to normalise the funding systemhave been drafted. Proposals have been submitted to the Riga City Council, and theirimplementation will help to update the renovation process of multi-apartment buildings in Riga.5) International project “Covenant of Mayors in the Central Baltic Capitals (COMBAT)”(PVS ID 2621) funded by the Central Baltic INTERREG IVA programme. The leadingorganisation of the project is the local government of Stockholm, but its cooperation partners –Riga (REA), Helsinki and Tallinn. The project is to be completed in September 2011. The projectensured a possibility to draft the Action Plan for Riga city in cooperation with other capital cities,which occurred for the first time in urban practice, to specify the methodology for drafting and toprovide recommendations for improvement of this methodology. The Action Plan has been draftedby attracting as cooperation partners the state scientific institute “Institute of Physical Energetics”(by using the project's funding) and AS “Rīgas siltums”, as well as energy supply organisations,institutions of the Riga City Council, service companies and experts. The Action Plan wasapproved by the Riga City Council on 6 July 2010; it was also translated into English andsubmitted to the Covenant of Mayors Office in Brussels on 20 August, and the work to ensureimplementation of the plan has been commenced. The project envisages organisation of RigaEnergy Days, and therefore it provided financial aid for organisation of events in 2010. Inconclusion of the project, the first Progress Report on the course of drafting the Action Plan is tobe prepared.These international projects have contributed to the adoption of experience and acquisition ofinformation, and provided REA with possibilities to work competently on drafting andimplementation of the Action Plan for the city. The research materials of these internationalprojects have been included in the Action Plan.The following programmes have received the available funding from the EU Structural Funds(European Regional Development Fund (ERDF) and the Cohesion Fund) for implementation ofmeasures in the energy sector and renovation of buildings in 2010:1) “Improvement of Heat Insulation of Social Residential Buildings” (LVL 6 million). Theaid beneficiaries are local governments. The local government of Riga city (the Housing andEnvironment Department) has submitted an application for renovation of two social houses at thetotal cost of LVL 299 thousand. The ERDF funding amounts to 75 %. Renovation of thesebuildings is to be completed in 2011.2) “Measures to Increase the Efficiency of District Heating Systems” (LVL 6.7 million).The aid beneficiaries are heating companies. In 2010, AS “Rīgas siltums” submitted two projectapplications in Riga for reconstruction of heating networks in the length of 1.84 km andmodernisation of the heat plant “Vecmīlgrāvis” by installing two biofuel boilers with capacity of2x7 MW.53

In 2010, AS “Rīgas siltums” submitted an applicationfor construction of a biofuel cogeneration unit with electric capacity of 4 MW and heating capacityof 20 MW in the heat plant “Ziepniekkalns” in Riga. The unit is to be put in operation in 2012.4) “Improvement of Heat Insulation of Multi-apartment Residential Buildings” (LVL 44million). The aid beneficiaries are apartment owners receiving financial aid of 50 %. From 2009 to2010, within the framework of this programme nine multi-apartment buildings have beenrenovated in Riga, and agreements for renovation of nine buildings in 2011 have already beensigned.During recent years, the greatest aid for improvement of energy efficiency and mobilisation ofrenewable energy sources has been ensured by the Green Investment schemes – flexiblemechanisms of the Kyoto Protocol which form assets from selling greenhouse gas emissionquotas. Within two years, LVL 140 million have been attracted to this financial instrument, thusmaking it possible to fund the following energy efficiency programmes:1) “Increase of Energy Efficiency in Municipal Buildings (1st round)”. The localgovernment of Riga city (the Property Department of the Riga City Council) submittedapplications for renovation of 21 schools, which was completed in 2010 by receiving LVL 4.74million including LVL 4 million from the flexible mechanisms of the Kyoto Protocol.2) “Complex Solutions for Reduction of Greenhouse Gas Emissions in MunicipalBuildings”. The local government of Riga city (the Property Department of the Riga City Council)has submitted applications for heat insulation in 6 pre-school educational establishments, in 4 ofwhich the heating system is being changed from coal-fired boilers to wood chip boilers. The workin these sites will be completed in 2011.3) “Complex Solutions for Reduction of Greenhouse Gas Emissions in Buildings ofNational and Municipal Vocational Educational Establishments”. Riga did not apply for thismeasure.4) “Use of Renewable Energy Sources in the Household Sector (1st round)”. Theprogramme ensures aid to private owners mainly for installation of solar collectors and batteries,heat pumps and wind turbines. The number of supported projects is large, but the registration ofsuch projects is lacking, also in Riga. Implementation takes place in 2010/2011.5) “Use of Renewable Energy Sources in the Household Sector (2nd round)”. Theprogramme has been launched.6) “Low Energy Consumption Buildings”. Project applications are submitted by localgovernments and entrepreneurs. The local government of Riga city (the Property Department ofthe Riga City Council) has submitted applications for two sites – a pre-school educationalestablishment and a sports school, but the competition is very tough and allocation of funds –problematic.7) “Technology Transition from Fossil to Renewable Energy Sources”.8) “Complex Solutions for Reduction of Greenhouse Gas Emissions in ProductionBuildings”.9) “Increase in Energy Efficiency in the Buildings of Higher EducationalEstablishments”.10) “Development of Technologies for Reduction of Greenhouse Gas Emissions”.11) “Improvement of Public Awareness on Importance and Possibilities of ReducingGreenhouse Gas Emissions”.12) “Use of Renewable Energy Sources in the Transport Sector”.13) “Reduction of Greenhouse Gas Emissions of the Public Lighting Infrastructure”. Thelocal government of Riga city (the agency “Rīgas gaisma”) has submitted an application for thisproject.54


RIGA CITY SUSTAINABLE ENERGY ACTION PLAN FOR 2010-2020 ong>PROGRESSong> ong>REPORTong> ON IMPLEMENTATION OF THE ACTION PLAN IN 201014) “Development of Technologies for Reduction of Greenhouse Gas Emissions andImplementation of Pilot Projects”.During the last two years, the local government of Riga city has invested LVL 37.5 million fromthe budget of the local government in renovation of the city's public buildings, mainly educationalestablishments.CONCLUSIONS1) Taking into account the data included in the Progress Report, implementation of the Action Plancan be considered as satisfactory.2) A separate problem is caused by the slow development of renovation of multi-apartment houses,which in 2010 did not exceed 1 % from the total volume of work necessary at national level. Also,the technical condition of buildings constructed during the post-war period and according tostandard designs (approx. 6,000 in Riga, and approx. 12,000 in Latvia) is poor, and to improvetheir longevity, it is necessary to ensure renovation in the nearest 10–20 years. To achieve this, thefollowing tasks must be fulfilled:- to support establishment and operation of energy service companies (ESCOs) in Latviaby firstly ensuring the availability of funds for operation of ESCOs;- taking into account the bank crediting system that has been operating poorly during thepost-crisis period and the bad reputation of banks in the eyes of residents, toimmediately establish revolving funds on national and municipal level by attractingresources from the EU Structural Funds or other funds with an aim to grant loans to theassociations of apartment owners, to persons authorised by apartment owners accordingto the procedure stipulated by laws and regulations and to ESCOs for duration up to 15years with low and fixed interest rates (up to 3 % which is necessary to ensureoperation of the fund);- to introduce reduced tax rates for renovated houses during the loan repayment period,but no longer than 15 years, because after renovation the cadastral value and theproperty tax usually increases thus preventing residents from making the decision torenovate their houses;- to ensure for residents availability of the data about the specific energy consumption ofbuildings connected to the district heating system in the actual year.The progress report has been reviewed and approved by the Action Plan ImplementationManagement Boardon 29 September 2011.55
