Last week, Eco Soundings identified the Veterinary Laboratory Agency's HQ building in Surrey as possibly the most energy inefficient in the land. But Defra, the owners, have rushed to its defence, saying it is now powered by wind and is rated as "excellent".
Apologies, but it doesn't change the fact that the whole site of 100 or more buildings is still dreadful.
Happily, the VLA is installing new boilers, PV cells and wind turbines to some buildings, as well as fitting sub-meters to each building, so the good new ones won't get mixed up with the older ones. Eco Soundings fears that this will have the added bonus of making it impossible to know what the overall energy use is on the VLA site.
