Those of us who work in the Assembly will know how cold the Senedd can get. It's part of what you might call a drive for sustainability. Or turning the heating down to save the rainforests.
But the fact you can sometimes see condensed moisture when you talk in there on a cold day still isn't enough to fulfill the impeccable environmental credentials that the Senedd aims for.
A report to the Assembly Commission last December found "the building is currently consuming around 50% more electricity than it should need on an annual basis".
While the performance on heating was excellent, the Senedd was using noticeably more energy for lighting, broadcasting and computer equipment than anticipated.
We can only hope that in the drive for greater sustainability the Commission heads for the light switches, not the thermostat.
