HSP: building the future today

The design features of the Habitat Social Positif (Project HSP) stem from the shared wish of the town of Castelnaudary, Habitat Audois and the TERREAL Group, as a building envelope specialist, to build homes that combine year-round comfort with energy consumption significantly below that required under RT2012 thermal performance rules, at the same time as offering full access to persons with restricted mobility and keeping construction costs well within reasonable bounds.

This ambitious experiment is a trailblazer for the forthcoming RT2020 rules, which will set comfort and performance standards for new "positive energy" homes, i.e. homes that use less energy than they produce.
