The existing building had major groundwater and condensation issues, it was of typical 50s - 70s construction practice and therefore performed very poorly from a hygrothermal perspective. This was not necessarily a big problem as the house was primarily used as a holiday home, however in recent years, the client had made it more of a permanent home and wanted the building to support this change of use.
The client was aware of our expertise in high performance building and whilst did not explicitly want a Passivhaus, where happy to be guided by us on improving the house to the best hygrothermal standard possible. This is of course Passivhaus and we enjoyed turning this tired yet charming holiday home into an EnerPHit contender. Our client could not be happier, the home now balances at a steady 18-23 deg and %45-%55RH year round.
