The Passivhaus is a voluntary building standard, that exceeds the present regulations by far. Homes developed according to this standard will have a 90% reduction in heating demand of c15kWh/m²a, compared to a conventional domestic building, which has an average heating demand of  150kWh/m2a. These principles can be applied not only to the residential sector as the name suggests, but also to commercial, industrial and public buildings.

How do they work?

PassivHaus buildings are highly insulated and very air-tight. This means that they can get most of their heat from the sun, human occupants and any appliances used in the building. They may need a small amount of heat from more conventional heating systems.

Design and construction

The PassivHaus uses a combination of low energy building design and use of renewable and low carbon technologies. Achieving the major decrease in heating energy consumption required by the standard involves a shift in approach to building design and construction. Design is carried out with the aid of the 'Passivhaus Planning Package' (PHPP)

At brilliant futures ltd we are trained to use PassivHaus Planning Package and are able to undertake the assessment and assist with the certification of your development. We are also regular attendees of the annual PassiveHaus conferences to keep up to date with both Passivehaus certified products and to new developments. If you are interested in developing a passive house we can assist with:

• completion a Passivhaus planning package (PHPP) assessment
• Advice on design and detailing of U values
• Assist with specification of components and building services
