London’s first EnerPHit retrofit

Enhabit was a guiding force in the renovation of a Victorian terrace house in London to EnerPHit standards.

Our clients were undertaking a renovation of a building which hadn’t really had any work done to it since the 1960s. They knew that this provided the ideal opportunity to do something amazing and decided to go for an EnerPHit retrofit.

The modelled heat demand was 225 kWh/m2.year before the works and 23 kWh/m2.year afterwards. The team achieved an airtightness level of 0.87 ach @ 50 Pa.

We provided the initial design brief, detailed design work, onsite training and supervision and our Passisash triple-glazed windows.

Now that the project is finished, the client’s advice to anyone considering an EnerPHit retrofit is to “Get people that are buying into the objective that you want to achieve. You have to have a bit of passion and you have to have someone who wants to achieve that as well”.
