Code for Sustainable Homes In the Sustainable Energy Act 2003 the Government set out its statutory aim to save million tonnes of carbon from residential properties in England through energy efficiency measures by 2010. For new properties the Code for Sustainable Homes promises a step change in sustainable building practice.

10 With six levels of compliance being introduced from 2010 through to 2016, national builders and construction companies are looking at ways of introducing the new requirement within the design process without having to add in costly and timely solutions. MVHR - Mechanical Ventilation & Heat Recovery Whole house systems can prove very effective at reducing the heat load in energy efficient homes since they recover heat which would have otherwise been vented outside and therefore lost. Single room systems are proving an increasingly popular choice for small scale renovation projects. The introduction of additional mechanical and ventilation equipment within domestic homes creates one question: how are the service runs designed into existing house Designs without going back to the drawing board?
