With over 1,000 buildings in the UK now completed to Passivhaus standard, new analysis has found that the extra costs associated with these energy-saving builds has fallen – with future projections even more positive.

Back in 2015, the Passivhaus Trust estimated that on average meeting the standards set by Passivhaus could add between 15% and 20% on a build. However, as these builds have become more common, championed by industry experts including Kevin McCloud, new data has found that the extra costs associated have fallen to 8%.

In the near future, as skills and supply chains improve, this figure could fall to as low as 4% of build cost according to the Passivhaus Trust.
