Design strategies
| Planned occupancy | Two people |
|---|---|
| Space heating strategy | Natural gas boiler |
| Water heating strategy | Natural gas boiler |
| Fuel strategy | Natural gas boiler |
| Renewable energy strategy | None |
| Passive Solar strategy | All units modelled in PHPP for orientation, generally windows sized sensibly. |
| Space cooling strategy | Opening windows with basic ventilation outdoors. Overheating analysed in PHPP. |
| Daylighting strategy | No particular strategy given but natural daylighting maximized. |
| Ventilation strategy | Mechanical ventilation with heat recovery for background ventilation, opening windows for purge ventilation, and summer cooling. |
| Airtightness strategy | Ensuring properly detailed junctions and site supervision and on-site inspection with signed check list sheet. Airtightness membrane to roof, with airtightness tapes to joints. |
| Strategy for minimising thermal bridges | Continuous insulation maintained whenever possible, with an on-site inspection and check list sheet to ensure compliance. |
| Modelling strategy | Passive House Planning Package. |
| Insulation strategy | Floor U-Value: 0.14 W/(m2K) un corrected Wall U-Value: 0.19 W/(m2K) Roof U-Value: 0.11 W/(m2K) |
| Other relevant retrofit strategies | |
