The majority of the glazing was placed on the south elevation to make best use of the winter sun and sea views. This strategy reduces winter heating requirements through passive solar gains. The dwellings benefit from other sustainable low-tech solutions such as high levels of insulation, rainwater collection and exhaust air heat pumps. The green roofs help to blend the development into the landscape, improve biodiversity and reduce the speed of rainwater run-off. The strategy also provides an attractive outlook for residents in higher level apartments.
