Dundry Passivhaus Airtightness Testing

Our latest PassivHaus project, a private house in an exposed location at Dundry completed first stage airtightness testing before Christmas.  This is a key stage for PassivHaus projects, testing airtightness on the building envelope before starting second fix.  Ensuring the building is adequately airtight at this stage should ensure that final airtests are likely to be achieved.

The PassivHaus requirement is 0.6 ac/h. Testing carried out by Paul Jennings of ALDAS showed the building flew through this stage, achieving 0.3 ac/h - a testament to the (self-build) client’s attention to detail and the robustness of the ICF construction method.

Planning Approval for New Self-Build PassivHaus

gcp have obtained planning approval from North Somerset Council for a new home in the village of Dundry to the south of Bristol.  Located in green-belt, the project will replace an existing house that was very cold and draughty in the exposed location, with an extra-snug and energy efficient PassivHaus.

gcp’s in-house PassivHaus designer Colin Powell, has modelled the energy performance and optimised the design to enable the client to achieve a certifiable building on completion. We are now working with the client on construction design to ensure the home will be easy and efficient for the self-build team to construct to meet the exacting PassivHaus standards.
