Enhabit is celebrating the Passivhaus certification of a new timber frame family home in Woking.
Enhabit were initially engaged to provide low-energy heating and hot water system design, but ended up providing full Passivhaus consultancy services. This then led to the design and supply of a complete Structurally Insulated Panels (SIPs) system with integral airtightness layer. Enhabit also undertook the full mechanical services installation which included warm air heating, MVHR, solar thermal and solar PV.
Having led both the Passivhaus and overall systems design, Enhabit were well placed to ensure that everything was designed to work in harmony. However, in contrast to a typical consultancy, Enhabit’s role in actually supplying and installing both the building and the entire set of mechanical systems meant they were also able to ensure that the quality, installation methods and workmanship was all in accordance with Passivhaus standards – thus streamlining and simplifying the certification process.
However, this was by no means a straightforward project.
Enhabit inherited a design which was never originally intended to be a Passivhaus building. With orientation and external appearance fixed, Enhabit’s in-depth Passivhaus expertise was needed to adapt the building’s fabric specification to ensure Passivhaus was achievable. Internally, the client had chosen to install a complex home automation system and thus the mechanical systems had to be designed to be fully integrated whilst at the same time achieving Passivhaus criteria and standards.
Overall, this was a challenging and complex project which drew on the full range of Enhabit’s consultancy, design and installation services.
John Palmer, Managing Director at Enhabit, said: “This project was a great example of teamwork. We were lucky to have a very well informed and committed client who understood that achieving a Passivhaus was not going to be straightforward and was ready to work with us to make the project a success. I’m really proud of how the whole Enhabit team, across all disciplines, worked seamlessly to deliver the end result – a fantastic new Passivhaus home and a happy client.”
Enhabit’s client commented: “Enhabit has been crucial to the success of our project. They have supported us across the board – from Passivhaus modelling, to heating system design and renewables through to the actual supply and installation of the systems themselves. Throughout, they have been completely professional, dealing with issues as they have arisen and always ensuring our best interests are put first.
“We wouldn’t have completed the project without them, and I would wholeheartedly recommend their services to anyone building a low energy or Passivhaus home.”
