The Passivhaus experts

Working together closely in project teams, we guide our clients and their agents through the process of Passivhaus building, at every stage from feasibility and concept design through detailed design, procurement and delivery. As Certified Passivhaus Consultants and Designers we promise great customer service, excellent communication, exemplary planning and organisation and a willingness to learn and adapt. Currently we are working on over 55,000m2 of Passivhaus Standard buildings across the UK.

Why DeltaQ

In the climate emergency, we passionately believe that the Passivhaus Standard — which creates buildings with excellent indoor environments, low running costs and the lowest carbon emissions — is the right way to build. As well as new buildings, we also advise on the refurbishment of existing buildings, adopting the EnerPHit (Passivhaus retrofit) standard and other related standards (AECB Retrofit Standard).
