Last year the Government hit its target of building 200,000 homes each year in England, putting it on track to fulfil the promise it made two years ago to build one million homes by 2020. With this ambition however, comes increasing pressure on finite resources including energy & water. It also increases pressure on waste handling, roads and drainage. Sustainable designs attempt to join the circle of providing the requirements for dwelling without impacting on the environment for future generations.
Most developers will be aware of such schemes as Code for Sustainable Homes (CfSH) or Home Quality Mark (HQM) or BREEAM that establish a framework of standards for ensuring residential schemes achieve a certain level of sustainability. The standards include targets for:
- Energy & CO2 emissions
- Water Usage
- Materials (including sourcing)
- Surface Water drainage
- Water Management
- Daylighting / Sunlight provision
- Noise reduction / sound insulation
In terms of energy efficiency / CO2 the standards refer to current Building Regulations Part L encouraging developers to go beyond minimum compliance. Additional credits are provided for schemes that incorporate some form of renewable or Low Carbon technology into their proposals. This may include the use of:
- Photovoltaics (PV)/Solar Hot Water
- Heat Pumps
- Wind Turbines
- Heat Recovery
In terms of water usage targets are set for reducing the consumption of potable water through the use of efficient fittings, appliance and the installation of water recycling systems.
Higher grades of compliance are set at <80 litres / person per day compared to more typical <120 l/p/day.
