Passive House Retrofit - EnerPHit Project in Piha

- The owner of this Piha home had very specific requirements when they took on the renovation of their 2008 three-bedroom, two-storey concrete block-built home. The home had developed extensive mould within the structure, especially in the roof space due to interstitial condensation. Being extremely sensitive to mould, the owner wanted the complete removal of all the mould-affected areas as well as an assurance that no mould would form in the future. The EnerPHit - Passive House Renovation standard was chosen to ensure a warm, dry, healthy and energy-efficient build.
Darryl Sang of Sang Architects designed the project and Terry Bryers’s team completed the construction work.
The building envelope was improved by installing a continuous external insulation layer over the existing block work followed by a plaster cladding system. High performance, Passive House certified, timber framed double glazed windows with low E and low G value (high shading coefficient) glass were installed. The roof was replaced with a membrane warm roof system.
In order to achieve the desired level of airtightness, pro clima’s TESCON EXTORA® PROFIL corner sealing tape was used to connect the window frames to the concrete walls. The TESCON® VANA adhesive tape installation ensures the continuity of the airtightness layer from the walls to the warm roof. A pre-line Blower Door test returned an airtightness result of 0.8 air changes per hour at 50 pascals.

Awesome work by the builder. This was my first EnerPHit design and a good challenge but running the math model was way easier than the work Terry and team had to undertake.
