Code for Sustainable Homes Level 4

Jun 2010
In May 2010, the affordable housing scheme in St. Athan, Vale of Glamorgan for Wales & West Housing Association was completed.

The scheme was chosen by WAG to be a pilot project designed to achieve the Code for Sustainable Homes Level 4 for the delivery of 16 houses and flats of a variety of sizes. The site was designed with a southerly aspect to take advantage of free solar gains to offset heating, to achieve good quality day lighting and sunny external spaces.

Sustainability targets were an important aspect of the scheme from an early stage.  The strategy was to develop a modular form scheme to reduce the carbon footprint within the construction process by utilising MMC principles.  Thus a high percentage of the building fabric is prefabricated off site and renewable materials and local supply chains are utilised to their greatest potential.

Key characteristics of the project are MMC; Sustainable Urban System (SUDS); Air source heat pumps heating and hot water system; Under floor heating; Mechanical Ventilation with Heat Recovery; Ecological enhancement retaining supplementing hedgerows and Properties with increased space sizes.
