Passive house 

We are an approved Passive House installer. Passive house  is a voluntary standard for energy efficiency in a building, which reduces the building’s ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling.

While Passivhaus offer a low-energy standard for new builds, the equivalent for existing properties allows homeowners the ability to update their thermal performance, retrofitted.
