ACCREDITED PASSIVHAUS DESIGN
The Passivhaus approach to building design has been established for over 20 years, and over 30,000 certified buildings have been erected worldwide.
Passivhaus buildings provide supremely draught free thermal comfort with very low energy use and high air quality. Using a fabric first approach, this includes:
Well installed thermal insulation.
Air tight and thermal bridge free construction.
Filtered, fresh air ventilation with recycled warmth.
Site specific calculations of heat losses and gains.
If required, heating systems can be very small and simple.
Typical fuel use can be about a quarter of 2012 Building Regulation requirements or a tenth of most existing homes.
Renewable technologies such as photovoltaic panels and ground source heat pumps are not necessary, and therefore a Passivhaus building should require minimal maintenance and replacement of services.
The high comfort levels and low fuel bills particularly benefit elderly people in Sheltered and Care accommodation. With fossil fuel prices rising, and pension returns uncertain, the Passivhaus approach is ideal for Care Homes, Extra Care Developments and Care Villages.
Consistent high air quality is especially appreciated in schools, as research has proven that fresh air improves educational attainment by pupils. Very reduced running costs are appreciated by governing bodies.
Following detailed research of completed Passivhaus buildings it has been shown that real-life energy performance is very close to the design stage predictions.
The same principles can be applied to existing buildings using the related EnerPHit standard.
