Passivhaus Update
When your vision becomes reality…we visited our Northamptonshire Passivhaus today, and it is really taking shape.
By following the Passivhaus design principles, the proposed design is reflective of the local climate, and the methods utilised have enhanced the overall design ambition to create a standalone dwelling appropriate to the unique setting. The following points outline the design decisions taken in applying the Passivhaus methodology:
The building is set into the surrounding landscape, providing it with shelter and limiting the effects of the weather.
South facing courtyard with high levels of glazing in the South façade designed to maximise solar gains in the winter. Solar gains are mitigated in the summer by the inclusion of a brise soliel.
A highly efficient building fabric reduces the overall energy demand of the building.
An MVHR system to provide adequate fresh air and recover heat gains within the building (from household appliances and human occupancy).
An extensive green sedum roof helps to regulate the heat gains and losses whilst also reducing storm water run-off and increasing local biodiversity.
A Solar photovoltaic array on the roof will further reduce the buildings reliance on non-renewable energy sources.
Rainwater harvesting will be included as part of the proposed water feature for use as garden irrigation.
A heat pump will provide hot water and additional heating when required.
Materials have been sourced locally including local stone for the external walls.
