Design strategies
| Planned occupancy | 30 people working in different capacities, office, retail and workshop. |
|---|---|
| Space heating strategy | Thermal efficient building, heated by batch burning log boiler and solar into a thermal store. |
| Water heating strategy | Solar and log boiler |
| Fuel strategy | Timber from site management and waste pallets |
| Renewable energy strategy | Total of 5kw PV on site - grid connected. |
| Passive Solar strategy | Solar thermal on the walls to maximise winter gain and minimise summer gain. |
| Space cooling strategy | Shading from overhanging eves and natural cooling from vents and windows, a clerestory that opens for ventilation. Louvered vents for secure night time cooling. Added thermal mass within the thermal envelope. |
| Daylighting strategy | Windows and a clerestory. |
| Ventilation strategy | Vents, windows and because it is retail the continual passage of people through the doors. |
| Airtightness strategy | Target of better than 3 air changes was achieved after test results. Rested after 13 months occupation, some easy remedial work achieved a successful result. |
| Strategy for minimising thermal bridges | |
| Modelling strategy | |
| Insulation strategy | |
| Other relevant retrofit strategies | |
