How much extra does Passivhaus cost?

A new research report from the Passivhaus Trust includes independent costing modelling which finds that uplift capital costs, compared with current building regulations, can be as little as 2% for flats, rising to 3-5% for semi-detached homes. 

Costs and values of Passivhaus - Optimisation, capital cost, and value uplift also explores how experienced teams can eliminate uplift costs through early stage consideration of form factor, glazing design and simplifying building services.

It goes on to demonstrate how Passivhaus can deliver unexpected cost savings through reduced maintenance and void costs and potential utility connection savings through reduced peak demand.
