High thermal mass, underfloor heating and an air source heat pump. This self-build project was ahead of the low carbon curve.

A decade ago the designers of this custom-build project in Berkshire, were looking to the future with energy efficiency a top priority.

Along with the H+H Rå Build method of thin-joint aircrete construction, the installation of underfloor heating and an air source heat pump were key features of the build.

Rå Build (MMC) is a cost-effective way of building homes using masonry and is a great option for self-builds such as this. Notably for this project, Revolution Homes recommended the innovative H+H thin-join system due to its excellent acoustic and thermal properties.

The thin joint aircrete system was perfect for this project due to its air tightness and thermal mass; absorbing heat well and releasing it slowly throughout the day. H+H Celcon Blocks were used for the floor as the ideal accompaniment to underfloor heating, releasing absorbed heat slowly and avoiding temperature extremes.  

The end result of the build was a dwelling with high thermal performance, and importantly a B rating in the Energy Performance Certificate. Together with the air source heat pump and underfloor heating, the use of aircrete created a highly energy efficient home that meets the challenge of low carbon living.
