Melbourne City has mapped every rooftop within its borders for easy identification of potential for enhancing uptake of solar, cool and green roofs.
The roofs of Australian towns and cities are major solar power real estate, feasible platforms for electricity generation near the level it will be applied.While solar PVs are increasingly becoming usual sight on homes and larger buildings, many urban rooftops are still yet to realise their clean energy generation capability.
“Most of these rooftops are used only to store heating and cooling equipment. We could set them up to generate clean energy, increase property values and cool temperatures within the city,” stated Lord Mayor Robert Doyle.
Melbourne City’s Rooftop Initiative has indicated solar panels could be installed on 637-hectares of rooftops within its vicinity.
Outcomes of the project suggest that green roofs are most feasible in the more structurally heavy CBD, Port Melbourne, and Docklands vicinities. Huge commercial and industrial buildings outside the CBD could host useful arrays of solar panels.
“We want to work with the community to help reduce power bills and increase employment within the renewable energy sector,” stated Chair of the City of Melbourne’s Environment Portfolio, Cr Arron Wood.
“Rooftop solar will play an important part in helping us to reach our target of sourcing 25 per cent of the municipality’s electricity from renewable energy by 2018.”
Commercial and industrial building owners can produces affordable, clean energy– and without needing to charge any capital up front. In addition to Environmental Upgrade Agreements (EUA’s), large commercial solar installations can be installed under a solar power purchase agreement (solar PPA) or leasing arrangement; leaving a company’s cash-free for other investments while safeguarding against energy price hype.
