Component 1: Phase 1:

Component 1: Phase 1: Set up the EAU – Allocating staff – Installing basic equipment (see Priority Action #6) Phase 2: Develop a specific “GRP” awareness programme mobilising women and household owners, to promote energy conservation in housing, focusing on: - Promote the adequate temperature set at home: usually homes consume large amount of energy in 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, - Apply 3M sheets on windows’ glass/glazing to reduce the impact of solar radiation impinging on the external buildings, reduce cooling loads, and lower energy consumption. A rough calculation allows considering that a widespread awareness campaign could result in a 30 per cent reduction of electricity consumption (estimation being more difficult on other fluids) in 50 per cent of households. Component 2: The plan is to develop solar PV and SWHs, wherever possible and appropriate in residential buildings. All combinations are possible, from small 5 kW units on a roof to larger units of 200 kW or even more when surface available allows it: - Promote the use of SWH systems instead of the current electric water heating (EWH) systems. Currently, in most of residential buildings EWH systems are in use due to low electricity tariff. - 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 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 such devices. The price of the SWH can be calculated and deducted virtually from the monthly electricity bill and given to the company in exchange of hot water delivery service through the installation of a SWH. This could be done for 2-3 years; the occupants will own the SWH after that period and will eventually save money from 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 improving comfort. To design and implement an adequate energy-retrofitting plan for residential buildings, the City of Luxor 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, 154

- 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 each housing unit has 25 lamps, that lighting represents 30% of the total electricity consumption of each household (4,350 kWh/y in average) and knowing that a switch to LED will cut consumption by 60% at least (a cut of 783 kWh/y), avoiding costs of 579 EGP or 28 €. As cost of replacement lamps will not exceed 90 € (75 EGP / 3.60 € per lamp) return on investment will be secure in 3,5 year or less. Considering a 1st phase of 320 buildings/ 6400 units the necessary investment will be 11.8 million EGP or 576,000 € (25 LED x 20 households x 320 buildings = 80,000 lamps at 3,6 €). A second phase of investment could be promoted in the second year of the programme, with the same target, leading to a global investment of 576,000 x 2 = 1,152,000 €. This investment should be managed as a revolving fund. Lamp replacement offers a 3,5y payback. Meaning, both funds will be fully replenished after 5 years and would be used to support a new round of lamp replacement. The electricity can engage in the lamp replacement, but this contribution is not necessary for the replacement to happen. The replacement plan could be launched as major awareness raising initiative promoted by the City council with a potential political gain that would help implementing other activities. SWH Systems – considering a daily consumption of 95 litres per person, average households with 4 people and 20 households per building we would need for one building: 95 x 4 x 20 = 7,600 litres requiring 33 collectors (2,5 x 0,9) for a total collector surface of 76 square meter (or 11 units of 3 collectors). This production capacity represents a total production of 69,920 kWh/y avoiding an expense of 51,800 EGP (2520 €). One unit (300 litres tank and a set of 3 solar collectors’ planes - 2.50m x 0.9m) costs 12,000 EGP (584€), hence the return on investment is secured in 2,5 year (584 € x 11= 6,424 € >> 6,424 €/ 2520 € (cost avoided / y) = 2,5 y). Two options can be promoted: • Allocation of one unit (1 or 2 collectors) per households, and • Global installation per building (average 20 households) and meter per household for hot water consumption. Both set up are workable, when the collective will offer more efficiency hence higher reduction of cost per households Considering a 1st phase of 160 buildings / 3200 unites the necessary investment will be 11 SWH units (for 20 housings) x 160 buildings = 1,760 units (tank + 3 collectors) for a cost of 21.1 million EGP or 1 million €. 155
