Design strategies
| Planned occupancy | The Research House occupancy numbers will vary during its use depending on which faculty is using the facilities. It is not envisaged the numbers will reach over 10-15 and will not have permanent occupancy. |
|---|---|
| Space heating strategy | Radiators fed via CHP Plant and gas fired boilers. |
| Water heating strategy | HWS cylinder fed via CHP Plant and Gas fired boilers. |
| Fuel strategy | CHP Plant and gas fired boilers |
| Renewable energy strategy | |
| Passive Solar strategy | |
| Space cooling strategy | |
| Daylighting strategy | Windows limited to two elevations only, and located within a courtyard situation. |
| Ventilation strategy | Mechanical fresh air extract ventilation via whole house ventilation unit |
| Airtightness strategy | Constructed to AECB standard details |
| Strategy for minimising thermal bridges | Constructed to AECB standard details |
| Modelling strategy | SAP |
| Insulation strategy | Pipework and ductwork insulated in accordance with Building Regulations |
| Other relevant retrofit strategies | |
| Contextual information | The Research House has been developed as part of a wider refurbishment project, therefore the location, orientation, height and opportunities for glazing were all constrained by the existing site, as well as security and planning considerations. It was planned as a 'typical' two up/ two down terraced house that makes up a large proportion of the housing stock of the city. The site is severely sloping, and the house is set within a courtyard to the front and back. Issues regarding ground water, and asbestos found within the existing floor slab of the mill have influenced the design and how services can enter and exit the house. The house is not stand alone and receives it energy supplies from the main building. |
Building services
| Occupancy | The Research House occupancy numbers will vary during its use depending on which faculty is using the facilities. It is not envisaged the numbers will reach over 10-15 and will not have permanent occupancy. |
|---|---|
| Space heating | Radiators fed via CHP Plant and Gas fired boilers |
| Hot water | HWS cylinder fed via CHP Plant and Gas fired boilers |
| Ventilation | Mechanical fresh air and extract ventilation via whole house ventilation unit |
| Controls | The Primary Heat source to the Research House is controlled via the BMS for the whole building. However the Hearing Interface Unit has integral controls for hearing and domestic hot water. The whole house ventilation system operates continuously when the house is occupied but does have a boost facility |
| Cooking | Electric hob cooker installed |
