 A detached 1950s house, typical of its time, built from reconstituted Bath stone blocks with cavity walls and all windows facing east-west. The building needed major refurbishment so the owners took the opportunity to significantly reduce its energy demand, whilst also rebuilding at the side where a garage was poorly linked to the main house by an enclosed passageway.


The ground floor was stripped back to the foundations and deep insulation laid beneath a slate floor with underfloor heating pipework.  Solar thermal tiles now supply a large thermal store, with an efficient gas boiler as back up. Water and waste pipes have been re-sited so that the outer skin of the house is no longer penetrated. Loft insulation has been meticulously linked to the top of the walls and the eaves once the wall cavities were insulated. Mechanical ventilation with heat-recovery is fitted in the first floor void. New triple-glazed windows units and external wall insulation have been installed.

Results

An airtightness test measured air permeability of the house as 3.8m3/h.m2, better than the Energy Saving Trust’s  recommendation of 5m3/h.m2. An Energy Performance Certificate gave an energy efficiency rating of 84% and an environmental impact rating of 86%. The solar thermal roof slates provide virtually all the heat required during summer months, and usefully supplement the gas input at other times of year. Regular meter readings show that energy consumption has  than halved thanks to the reduced heating needs.
