Residential – Private:  Construction of a PassiveHaus – Mosshayne Farm

Residential – Private:  Construction of a PassiveHaus – Mosshayne Farm

The project is the construction of a Passivehaus dwelling at Mosshayne Farm, Westclyst, Exeter.

The dwelling is split into a ground and first floor apartment, with a turret-style mezzanine roof. The build is designed and built to PassiveHaus standard, using renewable energy sources including GSHP and Solar PV. As the build is split into 2 separate apartment, both floors had their own air-tightness envelope. Both apartments passed Passivehaus airtightness criteria of 0.60, achieving air permeability ratings of 0.57m3/(h.m2).

The scheme consisted of the following building technologies:

• Porotherm clay block construction
• PCC plank floor construction
• Triple glazed timber & aluminium windows
• Zinc roof coverings
• Ground source heat pumps (GSHP)
• Mechanical ventilation heat recovery (MVHR)
• Underfloor heating
• Solar PV
• Pro Clima membrane and taping systems
• Alsecco render finishes
