Four storeys were erected in five weeks using factory manufactured ‘Dubel-Holz” solid timber structural panels for walls and floors. The building envelope utilizes triple glazing (U value 0.7 W/ m2K), high levels of insulation with 200mm recycled newsprint to walls (U value 0.15 W/ m2K) & PUR rigid urethane insulation to roofs (U value 0.17 W/ m2K). The air tightness tests ranged from 0.4 – 0.6 h-1.
Each house has rainwater harvesting feeding WCs and laundry, whole house ventilation with heat recovery and ground source heat pumps providing heating and DHW. The energy required for space heating is calculated to be 11 kWh/m2/yr and given the efficiency of the ground source heat pump this will result in energy costs of approximately £80 year - less than the cost of a cappuccino per week.
The houses are designed with generously proportioned windows giving good quality natural lighting during daylight hours. LED low energy light fittings are used throughout. User operated retractable external venetian blinds on the south elevation reduce solar gain and with the ventilation system the frequency of summertime overheating (over 25 0C) is projected at less than 3% providing exceptional levels of comfort and climate change proofing.
