Red Sea. The GRP will

Red Sea. The GRP will also increase the use of RE to improve the Governorate’s sustainable energy prospectus, yet contribute to achieving Egypt’s Vision and National Sustainable Development Strategy (SDS) 2030. Implementation plan Component 1: Phase 1: Setting up the EAU – Allocating staff – Installing basic equipment, Phase 2: Priority programme targeting municipality staff with basic information on climate change and energy: - Reduce artificial lighting and take advantage of daylight, - Manage temperature inside buildings to reduce use of AC/heater, - Shut down electric equipment at end of working time, and - Remove electrical pins from electrical socket when the day ends. Phase 3: Develop a specific programme “GRP”, mobilising women and household owners. Thus, mainly focus on: - Promote the apt temperature set at home: usually homes consume large amount of energy I summer when a reasonable cooling/ heating temperature can result in 20-30 per cent cut in energy use, - Foster behavioural changes at home: turning off lights when not in use, good management of refrigerator, washing machines’ time of use, boiling waters in kettles, and replacing classical bulbs with efficient devices such as LED lamps, - Advance use of energy efficient cooling/ heating devices: with good devices enough to ensure efficient performance. People usually buy inexpensive equipment without taking into account the higher level of energy consumption – even with green labelling devices act, this could lower energy consumption, but more awareness is needed to emphasise on buying green label appliances, - Control elevators’ use: set operation programme and limit their use to 3 rd floor unless users have medical issue/problems, - Adjust Air conditioning systems’ thermostats: be always at 24 degrees Celsius in summer, which would save up to 25 per cent of the energy consumption, and - Apply 3M sheets on windows’ glass/glazing: would reduce the impact of solar radiation impinging on the external buildings’ façades, reduce cooling loads, and lower energy consumption. A rough calculation allows considering that a widespread awareness campaign could result in a 20 per cent reduction of electricity consumption (estimation being more difficult on other fluids) in 50 per cent of households and private buildings. Component 2: The plan is to develop solar PV and SWH wherever possible and appropriate in residential buildings. All combinations are possible, from small 5kW units on a roof to larger units of 200kW or even more when surface available allows it. Such project should focus on few measures: - Promote the use of SWH systems instead of the current electric water heating (EWH) systems. Currently, in most of residential buildings EWH systems are used instead of SWH due to low cost electricity tariff during 2010- 2015. With the increased in tariffs, this action could tremendously reduce electricity consumption. - Develop a partnership with a bank acting as a “third party investor” that will support the investment solar energy units’ installation (for example through a process where the bank will cover the cost of the loan from a part of the savings allowed by the installation of PV and SWH programme), - Involve and train staff and companies that provide and sell PV and SWH systems to identify the benefits of installing the SWH instead of the EWH. The price of the SWH can be calculated and deducted virtually from the monthly electricity bill and given to the company as it represents the amount of saving. This could be done for 2-3 years; the occupants will own the SWH after that period and will eventually save money due to this installation. Component 3: On the long term, it would be necessary to develop a renovation programme targeting less energy efficient building, where basic buildings envelop insulation could significantly reduce energy use while improve comfort.

design and implement an adequate energy-retrofitting plan for residential buildings in the City of Hurghada - Governorate of Red Sea should engage in the following steps: - Assess the need through a detailed mapping of housing units, registering average energy consumption per square meter, date of construction and orientation, - Train small local companies that will have the flexibility to work in different type of conditions while performing adequate retrofitting programmes, the result in significant energy reduction, - Develop a partnership with a bank acting as a “third party investor” that will support the investment (for example through a process where the bank will cover the cost of the loan from a part of the savings allowed by the retrofitting programme), - Promote retrofitting in selected targets offering the best potential in terms of return on investment and, elaborating on these showcases further deploy the plan. LED lighting - Considering the pilot phase of 50 buildings representing 1000 housing units of similar capacity, and assuming each unit has 25 lamps, replacement requires 25,000 LED lamps. Given the cost of 75 EGP (3.62 € per lamp), the total cost for 1000 units amount to 1,875,000 EGP (90,000 €). These LED lamps would save at least 70% of the energy consumed for lighting (i.e. 20% of electricity consumption in residential buildings). An average housing unit consumes 4,575 kWh/y of which lighting is 915 kWh/y. Switching to LED cuts by 640 kWh/y. Electricity consumption reduction for 1000 units represents 640 MWh/y and avoids 351 tCO2eq/y. SWH Systems - One building represents in average 20 housing units occupied by 20 families, each encompassing 4 persons each. Such a family would need 70 gallons per day (265 litres) of which 25 gallons day (95 litres) need to be hot water. This means for one building 95 x 20 = 1,900 litres of hot water per day, requiring at least 20 collectors or 7 SWH units (sets of 3 collectors (2.50m x 0.9m) with a 300 litres tank). Such a unit costs 12,000 EGP (582.00 €) (all inclusive). The SWH cost per building will be then 84,000 EGP (4,074 €) producing 18,400 kWh/y and avoiding 10 tCO2eq/y. Avoided electricity consumption represents 648 €/y allowing a 6 years R.o.I (at 2017 electricity price). Note: SWH systems can be assigned to one family or preferably manage collectively, as this will be far more energy efficient. Then the building manager will ensure the proper maintenance of equipment and will ensure adequate payment of hot water consumption per households to reimburse the initial investment and cover maintenance cost. Such a payment will be cheaper than the electricity consumed for the same service as price of electricity goes up. The pilot phase of 1000 housing units, in 50 buildings represents: • 203,700 € investment for 50 x 7 SWH units, • 920 MWh/y avoided electricity consumption, and • 504 tCO2eq avoided GHG. Energy Efficiency measures – Housing refurbishment Beyond raising awareness, switching lamps to LED and promoting SWH, there are basic refurbishment actions that will lead to further energy consumption reduction in housing units. Such actions can entail: switching AC to more efficient device, improving ventilation, and tacking advantage of natural light. A lump sum of 12,600 EGP (600 €) will be allocated for each housing unit included in the pilot phase. In average, a housing unit consumes 4,575 kWh/y of electricity meaning 3,390 EGP/y (161 €/y) and 3,258 kWh/y of fossil fuel (natural gas, liquid gas, fuel) at a cost of 1,238 EGP (59 €/y). As refurbishment could allow a 40% cut in energy consumption, the annual saving would reach 1,851 EGP/y - 40% of annual expenses at 4,628 EGP/y - meaning 88 € (40% of 220 €/y). Compare to the initial investment of 12,600 EGP we will have a 6 years RoI (more or less depending on variation of energy costs). The pilot phase (1,000 housing units) will require and investment of 600,000 € offering an energy efficiency gain of 3,186 MWh/y and avoiding 1,326 tCO2eq/y and saving 155
