This includes:<br />

- Switch from AC/ Heating reverse systems to central management of heating and cooling.<br />

- Switch to LED lighting installation and incorporate motion sensors in offices of Governorate buildings.<br />

This device turns the lights off during un-occupied periods. This can reduce lighting consumption by<br />

20% to 80% depending on the occupancy type of these spaces.<br />

A case study conducted by MoERE and UNDP (Wati Al-watt Initiative) in public buildings, including<br />

Government buildings in Cairo, demonstrated that a 9.5 million kWh saving per year (an equivalent to a cut<br />

of 5.6 million EGP (equivalent of 265,260 €) could be easily achieved when LED lamps with different wattage<br />

were installed. The fact came after assessing 22 projects (first phase) at an approximate investment of 340,910<br />

EGP per project (equivalent of 16,148€). Such efficient lighting, in main areas was developed with a pretty<br />

limited investment of 7.5 million EGP (equivalent of 355,259 €) 68 . These technical solutions need to be tightly<br />

monitored to register impacts on energy consumption reduction to prepare progressive enlargement to a<br />

larger number of targeted building.<br />

Assumptions:<br />

- Price of 1 LED Lamp = 75 EGP (3.60 €),<br />

- Cost of a Solar PV unit with a 1KW power unit outside Cairo 1,500 US$ (1,278.5 €),<br />

- 1 kW in <strong>Egypt</strong> would produce around 5.2 kWh/day and 1898 kWh/ yearly,<br />

- According to <strong>Egypt</strong>ian Electricity Transmission Company (EETC), the FiT (feed-in-tariffs) agreement of<br />

2017 for solar generating electricity means that 1 kWh for commercial activities less than 500 kWh<br />

will be paid 108.58 piasters (0.053) per kWh, or 78.8EGP piasters (0.040) for PV plant between 500<br />

kW and 20 MW, and<br />

- Cost of a Solar Water Heater unit (3 collectors) producing 2,760 kWh is 12,000 EGP = 584 €.<br />

Switch to LED lamps and sensor systems<br />

Replacing lamps in all public buildings with LED devices, would require installing 8,500 LED lamps (1 lamp per<br />

10 square meters over 50% of the entire building area of 175,500 m 2 ). This would cost 30,600 for buying lamps<br />

+ 9,400 for sensors hence a total investment of 40,000 € (822,000 EGP).<br />

Energy saved from such new equipment would represent 283 MWh/y (60% reduction in electricity<br />

consumption dedicated to lighting) representing an economy of 10,190 € (209,420 EGP) per year, allowing 4<br />

years payback.<br />

Switching to more efficient AC devices<br />

Switch from AC/Heating reverse systems to central management of cooling/heating in 50% of these buildings<br />

is estimated 150.000 €. This will generate savings of 987 MWh/y (30% reduction on 70% of global electricity<br />

consumption in public buildings) avoiding a cost of 35,450 €/y (730,380 EGP) allowing a 4,5 years payback.<br />
