___________Introduction
The design & build project led by CCG (Scotland) Ltd on behalf of West Dunbartonshire Council, will provide 6 homes designed to achieve Passivhaus Classic accreditation and 20 homes built to CCG’s Net Zero Home standard and has been designed by MAST Architects.
___________Sustainability
The project is split into two different energy strategies. 6 plots will be constructed to the Passivhaus Classic standard, which is low energy building standard with rigorous quality standards that are independently assessed and accredited by the Passivhaus Institute in Germany. The remaining 20 homes will be built to CCG’s Net Zero Homes standard, which sees a combination of a fabric first approach, married with a low carbon heating, renewables and energy storage.
All homes will be will achieve Silver Active accreditation under Section 7 (Sustainability) as a minimum. The Passivhaus units achieve Aspect Gold Level 1 (Carbon Dioxide Emissions) & Aspect Gold Level 2 (Energy for Space Heating), whilst the Net Zero Carbon homes will achieve Aspect Platinum Level 1 (Carbon Dioxide Emissions). All homes will be heated by Air Source Heat Pumps, ensuring they are hated by a zero direct emissions heating system.
The Net Zero Carbon homes will benefit from between 8-12 solar photovoltaic panels (PV) linked to 13.5kW Tesla Powerwall electric batteries. All homes will benefit from high levels of fabric performance, with triple glazing as standard. The Passivhaus homes will benefit from Mechanical Ventilation with Heat Recovery (MVHR).

Carbon Futures have been appointed to provide the role of Passivhaus Consultant, responsible for ensuring that the project achieves Passivhaus Classic certification from the Passivhaus Institute in Germany.
