A Passivhaus social housing development designed by Hughes Architects has been recognised in a second national award nomination.

The development of energy-efficient homes at Sarn, near Newtown, Powys was constructed by Pave Aways.

It has already been shortlisted at the Property Awards Wales 2021 and now it’s been named as a finalist in the building performance category of the 2021 Building Awards.

The finals of the Property Awards Wales take place on 15 September. Hughes Architects has also been named a finalist in the Architects Firm of the Year Award.

The development at Sarn was a £1.3m Passivhaus scheme designed and built for Powys County Council.

“We’re very pleased to see the Passivhaus scheme revealed as a finalist in yet another award. It’s great to see a local authority such as Powys County Council committing to such developments. This was the first of its kind in Powys,” said Richard Lewis, a Director and Architect at Hughes Architects.

Passivhaus is a method being spearheaded by Hughes Architects as part of its commitment to the RIBA 2030 Climate Challenge. The challenge is to help architects meet net-zero (or better) whole life carbon for new and retrofitted buildings by 2030.

Passivhaus is a quality assured standard for low energy buildings. Such designs can help create buildings that use 75 per cent less energy than conventional new build properties.

Key elements of a Passivhaus design are:

  • Super insulation
  • Stringent levels of airtightness
  • Minimal thermal bridging
  • Optimisation of passive solar gain
  • Mechanical ventilation with heat recovery
  • Simple compact shape

The scheme used Welsh timber for the frames and cellulose fibre insulation made from recycled newspaper was used to cut down on the use of plastic.
