Mayville Community Centre
Download
as PDF The Mayville Community Centre project involves the complete passivhaus refurbishment of an existing community centre near Newington Green by bere:architects. The building, originally built in the 19th century to house a tram power generator, was converted for community use in 1978. The previous use and condition of the existing building means that annual energy demands provided a large financial burden for the centre. A full Passivhaus refurbishment included 300mm external insulation and render to the brick walls, 300mm insulation and wildflower meadows to the two flat roofs, 400mm insulation to the new pitched roof, triple glazed doors, windows and roof lights, 18kW/p photovoltaic panels, 4sqm solar collector, heat recovery ventilat...

Design strategies
| Planned occupancy | Varies 25 -150 people |
|---|---|
| Space heating strategy | Wall mounted radiators in the rooms and corridors, heated via the ground source heat pump. |
| Water heating strategy | Solar hot water, 55% of the water will be heated by solar thermal collectors and the remaining 45% will be heated by a gas condensing boiler. |
| Fuel strategy | Mains gas. |
| Renewable energy strategy | Solar hot water and solar electricity (PV is planned to generate 9,500 kWh per year). |
| Passive Solar strategy | The window proportions are optimised using PHPP, maximising passive solar energy. |
| Space cooling strategy | A high level of thermal mass in the concrete floor and the brickwork walls as well as cross ventilation avoid overheating in the summer. Night cooling benefits from openable roof lights which have been optimised using dynamic modelling. |
| Daylighting strategy | All working and living rooms have been positioned to benefit from natural light. Window openings have been designed according to the occupation requirements. |
| Ventilation strategy | Mechanical heat recovery ventilation (winter) Natural ventilation with extract only ventilation in the bathrooms (summer). |
| Airtightness strategy | A parge coat on the exterior of the wall seals the brickwork and provides the airtightness. |
| Strategy for minimising thermal bridges | Thermal bridge-free construction throughout and all junctions are analysed using Heat2, a static thermal modelling programme. |
| Modelling strategy | |
| Insulation strategy | |
