THERMAL imaging cameras have revealed massive levels of heat escaping from some of Gloucester’s best known buildings.
Steve Perris, who runs heat loss prevention company Heat Tight from Painswick, hit the streets of the city at 4am to catch an unusual glimpse into buildings such as Shire Hall, warehouses in the Docks, Kingsholm stadium, HSBC on the Cross and Gloucester City Homes’ office.
Many of the buildings had red, orange and white patches, showing greater levels of heat loss.
Kingsholm Stadium fared better with yellow hues, suggesting medium levels of heat loss.
Mr Perris is hoping his analysis will shock people into thinking about heat loss in their own homes. He says much of the heat loss can be reduced with simple and cheap measures.
He said: “I was hardly surprised when I took these images and saw the results. In many of them there is a lot of heat loss from windows, such as at Shire Hall. At the Docks there was an old warehouse that was not very energy efficient and a newer one that had been renovated which performed better. When I carry out surveys at people’s homes I always say it is not all about replacing boilers and other expensive measures, you can do simple things to bring down your energy costs.”
The survey of the buildings comes at a time when concerns about the rising cost of energy bills remain high. Mr Perris said simple devices such as a magnetic filter or radiation booster fans, which cost £2.50 per year to run and sit on top of heaters, can help to cut costs dramatically.
Draft proofing a home can also save homeowners some £60 per year.
He uses a special ‘blower door’ which de-pressurises a room to allow him to search for heat leakages.
Gloucestershire County Council said it has improved the energy efficiency of Shire Hall.
Andrew McCartney, director of programme support at the council, said: “We work hard to reduce energy use and bring down costs year-on-year at all council-owned buildings. We’re doing this by reducing the number of buildings we occupy, improving the levels of occupancy of those we retain and making them as energy-efficient as possible, from replacing boilers and light fittings at the end of their life with more efficient ones to putting in additional roof insulation.”
