Passivhaus is a world-leading low-energy, high-quality, and high-comfort standard for building design and construction. In many ways, it’s a formalisation of Max Fordham's approach to building design that we’ve applied since our foundation in 1966: as its name suggests, it relies on passive environmental design strategies to reduce operational energy, and prioritises resident comfort. It’s now also an important part of our recommended recipe for net zero carbon buildings.

About Passivhaus

Passivhaus is proven to deliver buildings with a smaller performance gap between design and reality than current practice. It requires buy-in from the whole design and construction team at the earliest stages, so that crucial decisions around building form, airtightness, orientation, daylighting, solar gain, shading, and MEP design strategies can be made early on and adhered to throughout the design and delivery phases. 

Our first Passivhaus project was the Agar Grove estate redevelopment in Camden, London; a project where Passivhaus was specifically suggested as an approach to help address residents’ fuel poverty concerns. Since then, we have worked on some of the largest and most complex Passivhaus and EnerPHit (the Passivhaus standard for retrofits) projects in the UK – university buildings, student accommodation, workspaces, private houses, and social housing developments. We are confident in delivering Passivhaus at any scale. 

Our extensive team of certified Passivhaus consultants have backgrounds that range from MEP engineering to architecture. We are also one of a limited number of Passivhaus Certifiers and can offer this as a service tailored to the project needs, from checking PHPP modelling and compliance to sharing our experience from a range of project typologies and sizes.
