A newbuild house in green oak frame has been built by Oakwrights for self builder clients in Devon. The project has aimed for high levels of energy efficiency and has been designed using PHPP (Passivhaus Planning Package) by 21°’s consultancy service to optimise its energy performance.
21° ULTRA range of triple glazed timber windows and doors was chosen for the project, including inward opening windows, single doors boarded with grooves and outward opening double doors.
The clients commented:
“We chose the ULTRA range because it offered the U values and thermal efficiency that we needed on the project. The ULTRA windows and doors look very nice and people comment on how smart they look.”
A PAUL Novus 300 MVHR (mechanical ventilation with heat recovery) system with rigid steel ducting was designed, supplied and commissioned by 21°gr for the project.
The clients commented:
“We don’t notice the MVHR system – it is just ticking away on its own. We barely touch it and hardly ever need to use the ‘Boost’ button. The MVHR maintains a healthy level of humidity (40-50%) within the house so we have not had any condensation even in the coldest weather, and have the added bonus that laundry dries very quickly.”
