Design strategies
| Planned occupancy | |
|---|---|
| Space heating strategy | Air to water Heat Pump, with underfloor distribution. |
| Water heating strategy | Direct electric water heater |
| Fuel strategy | NA |
| Renewable energy strategy | NA |
| Passive Solar strategy | The large areas of glazing to the south assist with solar gain and allows natural light to penetrate deep into the floor plan, reducing the amount of artificial light required. |
| Space cooling strategy | NA |
| Daylighting strategy | NA |
| Ventilation strategy | Zenhder Group Nederland B.V., ComfoAir550 & ComfoAir XL 800Two different units are used in this project, ComfoAir550 with heat recovery rate of 84% working in the Lecture Hall, and ComfoAir XL 800 with HRR of 80% for the rest of the building, eff. specif. HRE: 78% |
| Airtightness strategy | NA |
| Strategy for minimising thermal bridges | NA |
| Modelling strategy | NA |
| Insulation strategy | NA |
| Other relevant retrofit strategies | BREEAM Excellent -energy standard |
| Contextual information | The Centre for Renewable Energy and Sustainable Technologies (CREST) for South West College in Northern Ireland, is an example of integration of the sustainable design and energy efficiency principles. |
