Some skimming work commences within the property.
The services cupboard is constructed in the bathroom.
It became apparent because of limited space that it would be very tight to incorporate all the necessary components, which included the boiler, twin-coil hot water cylinder, expansion vessels, and solar pump amongst other things.
An intermediate air tightness test was carried out;
The test indicated an air tightness reading of 3.4 m3/m2 at 50 pa.
This was quite a result, as the pre start reading was 15.1 m3/m2 at 50 pa. Areas were identified where some leakage was occurring, most of which could be addressed with some additional work and sealing up. However as previously suspected the metal to metal joints of the underside of the pod structure that were inaccessible will be impossible to fully address.
Once the property is fully plastered the test should improve. We will have to take a hit on this.
EMHA board members attend site for a visit of the retrofit property.
A demonstration 'Passiv Haus' retrofit project at Cottesmore Road, Leicester. We are part of the Technology Strategy Board's Retrofit for the Future competition aiming to achieve Passiv Haus energy standards for a variety of different property types and methods of construction.
