Residential buildings in

Residential buildings in the city consume a total of 257,782 MWh/year of electricity, with a connection rate of 100 per cent. Also, the annual natural gas consumption in residential buildings is 80,000,000 m 3 , and 494,026 LPG cylinder/year as well as 480 litres/year of gasoline representing a total Final Energy of electric, natural gas, liquid gas (LPG) and gasoline of 257 GWh/yr, 87 GWh/yr, 96 GWh/yr and 4 MWh/yr respectively. The Governorate of the Red Sea, in particular the City of Hurghada has the desire to move forward to holistically solve the challenges faced in the energy consumption of the residential sector by promoting a comprehensive plan to reduce energy use, enhance energy efficiency and promote renewable energy, incorporating solar PV and SWH systems. The “Green Residential Plan” (GRP) should integrate sustainability solutions and technologies to green the building sector in the city of Hurghada. Short-term actions (3 to 5 years’ time frame) There is a lot to do to raise public awareness on energy issues, inviting inhabitants to reduce their consumption and, as a consequence, cut their energy bill. This is to be applied on residential buildings. An awareness campaign doesn’t require a huge amount of money and can bring interesting results for both parties: the client learning to use less energy and the electricity utility improving its services. Such awareness campaign to promote efficient behaviour should focus on measures such as: - Promoting the proper temperature at home: using excessive air cooling is not good for the public health and results in huge electricity consumption. Adjusting air conditioning systems’ thermostats to be always at 24 degrees Celsius during summer would save up to 25% of the energy consumption, - Promoting behavioural changes at home: turning off lights, proper management of refrigerator, time of use of washing machines, boiling waters in kettles and replacing classical bulbs with efficient ones, - Promoting energy efficient cooling/ heating devices, as the one on the market are not good enough. People usually buy cheap equipment without taking into account the higher level of energy consumption, which results in a higher “global cost” over a certain period of time, compared to buying green label appliances, - Control elevators’ use to limit their use to the 3 rd floor unless users have medical issue/problems, and - Apply plastic sheets on windows’ glass/glazing to reduce the impact of solar radiation impending on the external buildings’ façades. A rough calculation is realized considering that a widespread awareness campaign could result in a 20% reduction of electricity consumption (estimation being more difficult on other fluids) in 50% of households and private buildings. Medium-term actions (3 to 10 years’ time frame) The most obvious plan to develop on the mid-term is the promotion of Solar Heating Systems to produce hot sanitary water and avoid unnecessary electricity consumption. - Promote the use of solar water heating (SWH) systems instead of the current electric water heating (EWH) systems used in most buildings. Currently, there are only few users of solar water heating systems in the city of Hurghada and this action could tremendously reduce the electricity consumption for the specific need of hot sanitary water. It will be important to demonstrate the financial benefit of choosing a SWH system against EWH one, - Involve and train companies that will produce, sell and install SWH systems, and - A possible model to market SWH would be to ask for a monthly fee that would be minimal compared to the electricity bill people are used to pay, allowing the company, not only to recover the cost of the installation after few months but get recurrent revenues on the long run, from “selling hot water” and ensuring the maintenance of the equipment. Long-term actions (5 to 15 years’ time frame) In the long term, it would be necessary to develop a renovation programme targeting less energy efficient buildings, where basic insulation and ventilation could significantly improve comfort while reducing energy consumption. 56

To design and implement an adequate energy-retrofitting plan for residential buildings, the City of Hurghada should engage in the following steps: - Assess the need through a detailed mapping of housing, registering average energy consumption per square meter, date of construction, location, - Train small local companies that will have the flexibility to work in different types of conditions while performing adequate retrofitting programmes aiming at significant energy reduction, - Develop a partnership with a bank acting as a “third party investor” that will support the necessary investment to cover the cost of the buildings’ retrofitting. The bank will recover the cost of the loan from a part of the savings allowed by the retrofitting programme, and - Promote retrofitting in selected targets offering the best potential in terms of return on investment and, elaborating on these showcases to further deploy the plan. The main constraints of such a plan will be the mobilization of appropriate resources to fund renovation programmes, as in many cases house owners will not have the fund to invest at the appropriate level. This is why such a programme requires a partnership between the Governorates offering the guarantee that retrofitting will result in actual energy bill reduction, and the bank providing the funds. Such a plan should also include the adoption of efficient cooling devices. In addition, it could include the installation of solar PV panels to contribute to renewable electricity production, or/and install vegetal green roofs (if possible along with Solar PV panels) to reduce high temperatures, especially during the very hot summer period in Hurghada. Expected results Assumptions: - Awareness can lead to 20% cuts in 40% of the households, - EWH consumes 30% of households’ electricity and the programme can manage to install SWH in 50 % of the households by 2030, and - Building retrofitting will concern 20% of the buildings by 2030, ensuring a 40% improvement in energy efficiency.
