We are delighted to have supported Bellway Homes (South London) in devising an integrated energy, overheating and daylighting strategy for the proposed residential-led development next to the River Wey in Guildford.

The development will provide 56 new flats, as well as associated car parking and cycle storage at ground floor level.

The proposed strategy aims to maximise energy efficiency and daylight levels, whilst at the same time keeping the flats cool in summer months so as to avoid any uncomfortable overheating. The strategy prioritises a fabric first approach in accordance with the Energy Hierarchy and aims to utilise passive cooling measures such as balcony overhangs and solar control glazing. Our daylighting analysis demonstrates how the above approach still enables all dwellings to receive good levels of daylight, as defined by BRE guidance and relevant British Standards. We were able to show that the proposed development will have no adverse impact on the sunlight received by neighbouring residential dwellings.

Finally, a photovoltaic (PV) array further underlines the priority this development places on the implementation of sustainable design measures. Our over-shadowing analysis and PV efficiency calculations helped to locate the most appropriate area of roof space for the array.
