Appropriate insulation
In the renovation process we will pump the wall cavities and externally insulate the house with 200mm of External Insulation. We put 400mm of Polysterene under the floor and 300mm of Cellulose in the ceiling.
Efficient windows
We fitted triple glazed German windows with a 0.85 U-value, these will protrude outside the walls and the frames will be covered on 2 sides by the External Insulation to eliminate Cold Bridging.

Efficient Equipment!
We will install a Paul HRV system which is certified by the PassivHaus Institute and a 14m2 Solar panel array facing towards the Winter Sun with a 1500L buffer tank for space and hot water heating. The Buffer-tank will also be periodically heated by a small 4kW wood burning stove!

Finishing and optimization are very important
We stopped the External Insulation at Finished Floor Level in this simulation.
We dropped the External Insulation 500mm below the Finished Floor Level in this Simulation.
We dropped the External Insulation 500mm below the FFL and Pumped EPS bead into the cavity in this Simulation.
