Design strategies
| Planned occupancy | Two occupants per semi-detached property |
|---|---|
| Space heating strategy | Heating from condensing gas boiler supplying bathroom towel radiators. |
| Water heating strategy | From heating system |
| Fuel strategy | Mains gas. Mains electricity |
| Renewable energy strategy | |
| Passive Solar strategy | Solar gains maximised using PHPP |
| Space cooling strategy | Natural ventilation for most of the cooling season. Modelled using PHPP to ensure frequency of overheating of the building is low. |
| Daylighting strategy | |
| Ventilation strategy | MVHR installed |
| Airtightness strategy | Beattie Passive build system provides airtightness layer integrated into build system |
| Strategy for minimising thermal bridges | Aimed for thermal bridge free design |
| Modelling strategy | Whole building was modelled in PHPP to ensure Passivhaus standards compliance |
| Insulation strategy | Beattie Passive build system on a timber frame filled all cavities with a layer of Platinum Ecobead insulation |
| Other relevant retrofit strategies | |
