Design strategies
| Planned occupancy | Five people, all out to work or school on weekdays. |
|---|---|
| Space heating strategy | Heating from gas boiler; Heat recovered from ventilation exhaust. |
| Water heating strategy | From main heating system |
| Fuel strategy | Mains electricity. |
| Renewable energy strategy | 4 kWp photovoltaic panel installed . |
| Passive Solar strategy | Window proportions optimised using PHPP. |
| Space cooling strategy | NA |
| Daylighting strategy | NA |
| Ventilation strategy | Comfort ventilation with heat recovery (winter) Openable windows (summer) |
| Airtightness strategy | Airtight membrane over roof structure sealed to outside face of Timber Frame. |
| Strategy for minimising thermal bridges | Thermal bridging analysis undertaken for all primary junctions interfaces Junctions assessed include: Ground floor junction, external corner, party wall, party roof, party floor, eaves, verge, window jamb, head and sill, door jamb, head and threshold. |
| Modelling strategy | Whole house modelling was undertaken in PHPP and dynamic simulation was used to assess the impact of our proposed solar-combi heating system with the results fed back into PHPP |
| Insulation strategy | NA |
| Other relevant retrofit strategies | NA |
| Contextual information | NA |
