SAP calculations (Standard Assessment Procedure), Energy performance of houses

Malishev Wilson Engineers have broadened their expertise into energy performance of dwellings as a strategic move towards sustainable design. We are now qualified to give advice to the architects and clients directly on energy performance of any domestic property. With our extensive knowledge of glass and glazing products with their thermal performance we can work around existing and new Part L regulations to accommodate large areas of glazing, what seem to be a growing trend in modern architecture despite the goal of reducing energy consumption by 20% in the near future. With our experience in construction in general and glass in particular we think that this will add value to our clients.

2010  Kinsley Place, Highgate
Complete rebuilding of existing house with additional basement facilities with around 100 square meters of glazing over 130 square meters of footprint of the house with overall improvement of energy performance of dwelling by about 40%.
2010  Westwell Road, London
Modest rear extension of a typical terrace house in London. By using high performance glazing and robust methods of construction and detailing nearly 10% of energy was saved.
2009 

Main façade, Art Centre, Colchester
Special analysis was carried out to establish the true thermal performance characteristics of a non-standard façade system, which comprised 250mm by 80mm thick solid steel mullions (nearly 2t each) and 2.3m by 3.8m high performance, double glazed units weighing about 600kg each fixed to them. Using a heat flow analysis, MWE established a system U-value of 1.4 W/m²C° for the whole façade, which complied with the architect’s demanding specification.

2009  Woodchester house, Stroud, Gloucestershire
Modern extension to a Grade II listed mansion in Gloucestershire, near Stroud. 180 square meters of high performance glazing was used over 140 square meters of the area of extension. By combining benefits of highly insulated glass and improvements on existing house we have managed to nearly halve energy consumption of the house.
