One of Aim’s earliest low energy designs, the White Dwelling was subjected to full 3D building simulation modelling. This allowed detailed analysis of heat and energy flows in real time, giving an accurate assessment of the building’s thermal and energy performance. The analysis resulted in modifications to provide the optimum solution for the home owner.

The room layout is arranged around a large South facing central living area to meet the owner’s criteria of a corridor free home, while maintaining liveability and low energy costs.

The envelope is airtight and super-insulated with recycled newspaper and fibre board. There is Mechanical Heat Recovery Ventilation throughout fed from an underground source, and under floor heating and hot water is supplied from a ground source heat pump. Summertime cooling is provided by the underground source ventilation and high level opening devices. All lighting is by low energy long life light emitting diodes.

All systems and materials are based on Passive House principles and the Green Guide to Specification.
