Passivhaus is a voluntary comfort and energy efficiency building standard developed in Germany and now commonly used all over Europe. It has been shown time and again to deliver the best results in home comfort and efficiency.

Our team includes a number of qualified Passivhaus designers and we have successfully completed some of the UK’s most challenging and pioneering Passivhaus projects including the UK’s first Passivhaus retrofit of a Victorian terrace.



We specialise in helping clients and designers with all aspects of Passivhaus design, engineering and building techniques.

– Design advice
– PHPP modelling
– Building fabric specification
– Thermal bridge analysis (THERM)
– Airtightness detailing
– MVHR design
– Heating design
– Project management

We can work with an existing design or start from the very beginning with you. The earlier the better.

About Passivhaus

Research has shown that new buildings can use 50-100% more energy than expected due to poor assumptions during the design, or lack of attention to detail during construction.

Passivhaus, in contrast, is a method built on the evidence and feedback of real low energy buildings that work. It controls performance risks through checks at every stage of the project. We proved its effectiveness in our very first project.

High levels of insulation for even temperatures.

High-performing triple-glazed windows mean no cold spots.

Thermal bridge-free design takes away moisture problems.

Airtight building envelope stops draughts causing discomfort.

Ventilation with heat recovery provides healthy amounts of fresh air without wasting heat.

The Passivhaus Trust recommends that the best way to achieve quality assurance for a Passivhaus project is through certification by a registered Passivhaus Certifier.

Enhabit works with certifiers to ensure the detailed and sometimes challenging certification process goes quickly and smoothly.
