A Northern Ireland property developer championing ‘Passivhaus’ standards says their homes cost around just £500 a year to heat and light.
The ‘Passivhaus’ concept has been around for over 30 years and aims to provide comfortable and cosy homes with as little energy use as possible.
This is done using five key design and construction principles to make such homes super insulated envelopes, airtight, with *high performance glazing, heat recovery ventilation and eliminating thermal bridging.
