Envirotech Building Services were appointed to deliver the first non-domestic building to achieve Passivhaus-Plus. The business centre was built to be a space for small businesses and co-working whilst also being as sustainable as possible for a building of that size.

Scope of Works

• Heating and cooling systems
• Mechanical and natural ventilation
• Domestic water services with above ground drainage
• Small power, data and lighting
• Fire alarm
• Photovoltaics

Being the first Passivhaus Plus project in the country, special attention had to be paid to the energy generation and consumption, with an array of photovoltaic panels spanning the roof generating roughly 45 kWh/(m²TFAa.)

The heating has been generated from the local district heating network, requiring a considerable amount of liaising with local councils and authorities for the below ground heating connections.

In the summer, the mechanical ventilation systems is supplemented with natural ventilation. The natural ventilation is provided by louvred ventilation panels, automatic openable windows and roof lights.

The eco centre was part of a new residential scheme, developing the entire area, constructing 94 zero carbon homes with the largest residential solar array.
