Bluesky is helping UK Housing Associations make the most of their housing stock's solar energy potential. Working with carbon reduction company Sustain, it is using high resolution aerial photography combined with detailed 3D models to measure the potential for solar energy generation for individual properties based on a number of contributing factors such as roof size and aspect. These measurements are helping the Housing Associations produce income from Feed-in Tariffs, reduce energy bills for householders and decrease carbon emissions.
