Energy Generation & Passive Ventilation

The building would be carbon negative in terms of the energy that it produces is greater than the energy that it consumes. PV panels positioned on the roof of the southern wing would export energy to the national grid during the summer months. In the winter months energy would be imported when there is less sunshine.

The south facing sculpted shapes on the south face of the northern wing would have recessed evacuated solar tubes that would use water to heat a heat sink encompassed within the sculpted shape.

The stored energy would be used to heat water when the sun is not available and would be particularly useful in the colder months when the sun is not so strong.

Heat Sink & Evacuated Solar Tubes

A heat sink would comprise of crushed recycled brick in a cementitious binder set in insulation.

Solar thermal evacuated tubes are concealed behind vertically aligned glazed screens that can also be removed for maintenance purposes.

Surface glazing to fascia and floor panels creates a homogenous link between wall panels.

Passive Ventilation

During the summer months the building would be cooled by air drawn in through the floor and exited through the clerestory windows. During the winter months the house would use a Mechanical Ventilation with Heat Recovery (MVHR) system.

SAP Worksheets

SAP calculations are a Building Regulations requirement for all new houses and conversions and some extensions. The Standard Assessment Procedure (SAP) is a measure of the energy efficiency of a property. Featured here are a selection of key SAP worksheets.
