Basix is the Building Sustainability Index. Basix is a planning tool designed to assess the potential performance of new homes against a range of sustainability indices: Landscape, Stormwater, Water, Thermal Comfort and Energy.

Basix aims to reduce the environmental impact of these features of new development and to produce homes that are more comfortable and cheaper to run than most existing homes.

The first stage of Basix focuses on reducing Water and Energy use. Basix has set targets for these indices which all new development must meet. Landscape, Stormwater and Thermal Comfort indices are also activated because information relating to these indices impacts on water consumption and greenhouse gas emissions.

A Basix certificate can be completed for you by the trained staff at Energy Efficiency Assessments.
