ERDF 102: Energy-smart authority

Energy Smart Authority included the conversion of the offices of Housing Authority in Floriana into eco-friendly, energy smart building. The project consisted of a Photovoltaic RES installation system to generate energy and the installation of Energy Efficient lighting system through lighting optimisers aiming to save on energy consumption.

In line with Housing Authority Energy Saving Policy the Authority aims to:1) to reduce demand on fossil fuels from the power station; 2) promote the use of solar energy by installing a 3.48kWp PV system; 3) promote efficiency in energy end use by installing efficient sighting system saving 10,212 kWh p/a; 4) contribute to the reduction of CO2 emissions by saving 13.5 tonnes; 5). be a catalyst in generating a significant shift in the approach to energy consumption.

1. Implement a 3.48kWp Photovoltaic system consisting of 17 panel generating 5232kWh p/a2. Install six lighting optimizers to reduce energy consumption by saving up to 10,212kWh p/a on energy consumption which around 30% of the consumption from lighting of the building used for this project.3. Total savings on electricity amounts to 15,444 kWh annually. This reflects 16% of our annual total energy consumption of the building to be used for this project.4. The RES and EE initiatives will save 13.5 tonnes of CO2 emissions5. 33% of the roof surface areas will be used to install the PV system. The remaining space will be investigated in the future for further possible installations6. The payback period of the initiatives was calculated: Lighting system - around 3 years; PV system - around 5 years. In terms of CO2 emissions for the production of PV panels, the PV system installed will pay back the CO2 emissions in 3 years.

The Housing Authority aims to introduce energy efficiency measures and RES in its public building with the intention to:1. Promote the use of energy efficiency and RES in the building sector2. Lead by example to the community to promote a greener world3. sensitize the public and private sector on the benefits of energy efficiency measures and RES
