Technical Solutions, Thermal Properties, Energy Use and Water
The building is designed with a passive philosophy to minimise the demand on energy and water for comfort and service requirements through design with a fabric first principle. The aim is then to provide heat and energy in the most efficient manner from the available resources. The location of this site and the restrictions on it make this philosophy paramount. On site we have a solar energy, a limited clean water supply and no drainage.
The building fabric is super-insulated and air-tight with the insulation to the outside of the construction keeping all the structure on the warm side. This gives a global heat loss U-Value of 0.12W/m2K and encapsulates the thermal mass of the structure to even out diurnal variation. All junctions in the construction are then detailed to minimize thermal bridging to achieve a linear transmission or psi value of 0.04W/mK. This will reduce the space heating demand to a minimum. We anticipate the space heating demand to be 892.80kWh in the month of January, and a total demand of 5000kWh/a or 14kWh/m2/a.
