The solar panels on the roof of AUA’s main building have been integrated into the facility’s domestic hot water system. As a result, about 70% of the hot water from any faucet in the building will now be heated through the use of solar energy.
The solar thermal collectors, installed between 1999-2002, have been used thus far to cool the air inside the small auditorium of the main building by a sophisticated process known as desiccant cooling. In addition to this, the panels will now be used produce hot water supply for use in the main building.
During sunny days, the solar thermal collectors produce up to 3 tons of hot water to provide for two days of water consumption in the main building.
The AUA main building also has 72 photovoltaic panels (total of 5 kW capacity) that allows AUA to produce electricity in its main building to meet the needs of the aforementioned Solar HVAC system, as well as emergency/server backup needs. Any excess generation of electricity is also sent to the national electricity grid.
A series of other measures to increase energy efficiency at the university are currently under development.
