consumption in such

consumption in such buildings could be cut by 30 per cent. Knowing that electricity consumption for cooling and heating represent 70% of the public building electivity consumption it is strategic to invest on this issue, in two directions: raising awareness of building users, switching to more efficient devices. Renewable energy: Some of the potential sites have been identified, and there are already pilot projects to test the benefit of solar PV with an installed capacity of 300 kWp. The Governorate of Luxor already developed a strategic plan to develop renewable energy on its buildings, but this plan still needs to be unrolled . Energy savings / short-term actions (3 to 5 years time frame) The Municipality is willing to develop initiatives to reduce energy consumption, but a consistent plan needs to be implemented. More efforts should be done in raising staff awareness on simple change of behaviour to save energy without significant investment: - Open curtains and window shutters during daytime to avoid artificial lighting when outside air temperature is between 22°C and 27°C, - Keep the inside air temperature between 24°C - 25°C even in hot period to ensure good comfort all year long and make strong cut in energy consumption, - Avoid elevator and choosing staircase when going up or down one or two floors, only allow employee with health problems to use elevators, - Turn off electric equipment at end of working time or when not actually used, and - Unplug all electricity cables from wall’s sockets as this could save about 5% of the energy use. It would be interesting to promote a challenge between services/units to invite all workers from the Governorate to make significant efforts in saving energy. The best performing service would be celebrated as “energy saver/climate saver’’ and would get a special gratification. The Environmental Awareness Unit (EAU) within the Governorate Communication Department will promote these activities. Energy-savings / long-term actions (5 to 15 years’ time frame) Beyond promoting awareness and behavioural change, it is necessary to develop a clear and comprehensive plan to replace old devices and equipment and install energy efficient systems that will help reducing electricity consumption. Ideally, this programme should be implemented, in a first phase, in a small number of buildings (starting with the more symbolic one: the main Governor’s building or city hall), covering all type of devices and equipment, in order to concentrate many initiatives on the selected buildings and demonstrate the benefit of these structural changes: - Switch from AC/Heating reverse systems to central management of heating and cooling; and - Switch to LED lighting and install motion sensors in offices. This device turns the lights off during unoccupied periods. This can reduce lighting consumption by 20%-80% depending on the occupancy type of these areas. A case study, by MoERE and UNDP (Wati Al-watt initiative), was conducted in public buildings including government buildings in Cairo, demonstrates that a 9.5 million KWh saving per year equivalent to 5.6 million EGP (€ 265,260) cut could be easily achieved by installing LED lamps with different wattage in 22 projects in the first phase at an approximate investment rate per project of 50

EGP 340,910 (€ 16,148), offering a very attractive return on investment 12 . The initial projects need to be tightly monitored to register impact on energy consumption reduction to prepare progressive enlargement to a larger number of targeted building. Obviously the design and construction of new buildings should follow more stringent rules and new requirements allowing far better energy performance. Expected results Assumptions: - Staff awareness will result in 10% reduction of all consumption due to behavioural changes. This level of reduction doesn’t appear to be hard to achieve, as there are currently no precautions at all to avoid unnecessary electricity usage. - Working on lighting will cut electricity consumption by 30% of this sector (20% of total electricity) - Efficient AC devices will cut electricity consumption by 30 % of this sector (70% of total electricity) Energy in MWh/year GHG in tCO2eq/year Situation in 2015 Cut expected in 2030 Situation in 2030 / BAU Energy GHG Energy GHG GHG (BAU) Cut / BAU All municipality buildings 4,718 2,595 - 1,740 - 957 3,347 29 % Staff awareness campaign (10% cut) - 470 - 258 Switch to LED lighting and sensor systems in buildings (30% cut) - 283 - 156 Switching to more efficient AC devices (30% cut) - 987 - 543 Note: Impact of long-term measures can only be assessed based on average ratio unless the Governorate defines the level of investment it is prepared to allocate to this topic. Budget These figures are rough estimates of budget required per action for the period 2018-2020 and ROI Staff awareness campaign (10% cut) 30,000 € 3 years Switch to LED lighting and sensor systems in buildings (30% cut) 40,000 € 6 years Switching to more efficient AC devices (30% cut) 100,000 € 4.5 years Street lighting Current status Street lighting in the City of Luxor consumes 5.6 GWh of electricity per year (2015 reference), which represents an overall annual cost of 4.2 Million EGP (equivalent 201,439 €). Note that this doesn’t include lighting of heritage sites. 12 Energy efficiency Project – Waty El Watt, UNDP and GEF, available at : 51
