Code for Sustainable Homes
‘An environment assessment method for rating and certifying the sustainable performance of new homes’.
Measures and certificates sustainability against 9 design categories.
Categories 2 and 7 are relevant for bathrooms
Category 2 = Water
Category 7 = Health and Well being (Includes
section on Life Time Homes)
New houses are assessed on water usage per
person as measured by the Water Calculator
(see Part G).
A rating of 105 litres is mandatory for Public Housing (Level 3).
All new private housing has to have a code rating, though there is no mandatory code requirement yet.
Our in house and external specification teams can provide you with assistance in meeting any of the code
levels above.
BREEAM
BREEAM is an environmental assessment method and rating system for buildings
A BREEAM assessment uses recognised measures of performance, which are set against established
benchmarks, to evaluate a building’s specification, design, construction and use. The measures used represent
a broad range of categories and criteria from energy to ecology. They include aspects related to energy and
water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and
management processes.
It encourages designers, clients and others to think about low carbon and low impact design, minimising the
energy demands created by a building before considering energy efficiency and low carbon technologies.
