In the UK we continue to construct new houses with minimum insulation, lots of thermal bridges and air leakiness. The result is houses that are carbon and energy intensive, are expensive to heat and suffer from condensation and poor internal air quality. PH15 is an alternative construction method that addresses these problems. Timber frame house constructions are common in Nordic countries and in Canada/US, where the self build market contributes over 50% of new houses built, and market/social housing is built by smaller family sized businesses. We would like to see a shift towards a similar pattern in the UK, away from the big ‘six’ volume developers. The UK must de-carbonise new housing to address the climate crisis we now face. PH15 comfortably delivers to the required 2030 standards now, ensuring low energy bills, healthy indoor air quality. PH15 can be accurately costed pre-planning, we advise typically 4-6% above current building regulation standard. On site, PH15 de-risks achieving the necessary demanding air-tightness target of maximum 0.6 ach @ 50Pa, our average result being 0.3 ach @ 50Pa.

NOTE: By adopting PH15 as your preferred construction method does not require you to certify to the Passivhaus standard. We have certified most of our early projects to demonstrate that PH15 is fully compliant to Passivhaus performance levels.
