Retrofit

Retrofitting Strategy	Renewable energy integrated with façade
	Add renewable energy source on roof such as solar panel, photovoltaic (PV) panel or wind turbine. Solar film, spray-on solar coating to reduce penetration of solar radiation to indoor space. Coating for PV upkeep the efficiency of PV panel. Building with BIPV integrated on its glazing:
	Consideration
	The two utility companies offer feed-in-tariff to incentivise the installation of PV panels and wind turbines. A number of options available including different types of PV panels, hybrid type wind turbine with PV panels, building integrated photovoltaic (BIPV) panels, solar panels for hot water etc. There are regulations limiting the height of the PV panel from the roof floor. Structural loading needs to be checked.
	Estimated Saving
