VELFAC high-performance glazing is installed in an exemplar eco-home in Brighton, the first private house in the city to achieve Code for Sustainable Homes (CSH) Level 5. The result of six years’ planning, the home has been described as ‘an example of brilliant simplicity’, and was a highlight of the 2015 Brighton Eco Open Houses weekend.

Passive solar house principals
Designed by Deacon and Richardson Architects, 57 Grantham Road features ‘every aspect of sustainability in a light and airy home’ says architect Dave Batey. Construction followed passive solar house principles, including solar orientation, self-shading and sun spaces, with VELFAC glazing specified for the system’s impeccable low-energy and environmental credentials, and for its stylish design. ‘We had specified VELFAC for previous projects and knew it could help us achieve the point score we needed for CSH Level 5, and for Secured by Design accreditation,’ explains Dave. ‘The VELFAC system met our required U-value target without the need for triple-glazing, and the clients also liked the clean lines and consistent slim sash frame sizes, maintained across multiple windows with different opening functions, together with very subtle trickle vents.’ 

Part of a natural ventilation system
VELFAC composite windows are installed in a variety of configurations throughout the single-storey home, including full height patio windows, and are also used as part of a controlled natural ventilation system. This makes sure the house remains comfortable throughout the year, minimising the impact of solar gain in summer, while retaining the free heat delivered through the VELFAC glazing during the winter months.

The outer aluminium VELFAC framing is finished in light grey, a contrast to the white render and grey brick exterior, and to the bright yellow external shading. The inner pine frame is finished in a clear lacquer to enhance the bright white interior, with the slim frame maximising natural daylight, further improving energy efficiency throughout the house.
