Innovative office retrofit

Bioregional has given an old office building in a conservation area a radical but sensitive refurbishment using pioneering energy saving technologies. This has slashed heating bills and made it more comfortable for staff.

Innovative carbon savings in a traditional setting

Bioregional initiated, developed and won full funding for this advanced office upgrade project from the UK Government’s Department of Energy and Climate Change – then managed its delivery with partners in 2014.

Bicester Town Council’s offices in Oxfordshire are situated in the Garth, a large 1830s hunting lodge in a conservation area off the town centre. The building needed major energy efficiency improvements but the heritage had to be respected.

The key innovation for this £840,000 project is WHISCERS (Whole House In-Situ Carbon and Energy Reduction Solution). This begins with laser measurement of each room, with the data then fed into a computer which is used to precision-cut large pieces of internal insulation and dry lining. These pre-cut panels are then installed on site, room by room, as if assembling a huge jigsaw on the inside face of the exterior walls. It was the first time this process had been used in a non-domestic building. It cuts wastage of material, costs about 30% less than conventional internal wall insulation and is far less disruptive for building occupants.

Also installed were ultra-thin aerogel floor insulation, air tightness measures, and secondary glazing. The project was completed with a ventilation system using both natural ventilation and mechanical ventilation with heat recovery. Oxford Brookes University is monitoring the building in depth for a year to evaluate energy saving and the comfort of office staff.
