Project details

Chartrange were appointed by Bowmer and Kirkland to undertake both groundworks and externals packages on Energy House 2, a research facility designed to test the energy efficiency of homes in different weather conditions. The 11,300 square feet facility is operated by Salford University.

The centre will be able to create snow, rain, wind or solar exposure in two giant chambers and record the impact that different weather conditions have on the four furnished test homes contained within the chambers.

Temperatures can be plunged to -20°C and raised to 40°C, meaning environmental conditions experienced by 95% of the world’s population can be replicated.
