Design strategies
| Planned occupancy | The development is planned to start occupancy in 2015. The Picairn and Hobart development has 42 units and will be phased occupancies |
|---|---|
| Space heating strategy | Each unit has an individual condensing mains gas boiler to water filled radiators |
| Water heating strategy | Each unit has an individual hot water cylinder heated from the gas boiler |
| Fuel strategy | Mains Gas as primary heat source |
| Renewable energy strategy | No renewable electricity generation. |
| Passive Solar strategy | All units modelled in PHPP for orientation |
| Space cooling strategy | Background ventilation by MVHR purge ventilation by opening windows |
| Daylighting strategy | kitchen to achieve a daylight factor of =2%.living rooms to achieve a daylight factor of =1.5% |
| Ventilation strategy | Mechanical ventilation with heat recovery - system 4 for background ventilation |
| Airtightness strategy | Ensuring properly detailed junctions and site supervision and on site inspection with signed check list sheet. VCL membrane to roof airtight tape joints to structure |
| Strategy for minimising thermal bridges | Specific details at all junctions - with an on site inspection and check list sheet with signatures. |
| Modelling strategy | Passive House Planning Package used to model energy strategy. |
| Insulation strategy | Wall U value = 0.15 W/mK. Roof U value =0.09w/mK. Floor U value = 0.14W/mK |
| Other relevant retrofit strategies | |
