|---|---|
| Space heating strategy | Air source heat pump to wet radiator system. |
| Water heating strategy | Solar thermal with immersion boost. |
| Fuel strategy | Continue reliance on electricity, with conservation and use of solar thermal and ASHP to reduce load. |
| Renewable energy strategy | PV and other renewable generation strategies evaluated, but cost effectiveness considered too poor for widescale rollout . |
| Passive Solar strategy | Continued reliance on solar gain from large windows to habitable rooms - no special measures for control or utilisation due to high thermal mass of structure (no internal insulation). |
| Space cooling strategy | Natural ventilation and ad hoc shading. |
| Daylighting strategy | Continued reliance on daylighting from large windows to habitable rooms. |
| Ventilation strategy | Controlled ventilation to be incorporated in replacement window units. |
| Airtightness strategy | Improvement through replacement of windows and elimination or caulking of service entry points. |
| Strategy for minimising thermal bridges | Additional loft insulation, carefully installed to cover gaps in existing insulation; and perimeter insulation to edge of ground floor slab. The scheme does not envisage additional wall insulation, so it is inevitable that thermal bridges will remain. |
| Modelling strategy | DEMScot whole-house model, based on SAP 9.82 and BREDEM. |
| Insulation strategy | Additional insulation to loft, flat roof and slab perimter as described above. |
| Other relevant retrofit strategies | Carnego smart control system and strategies to influence user behaviour. |
