Green Building Forum - No apparent heating but overheating in winter?

There are radiators with TRVs under all the windows but they are mostly off. No air con ducts. The building looks to have been built in the 60's and has obvious thermal bridges at each floor. Walls are only about 250mm so no room for fancy insulation. Windows are single glazed with poorly fitting secondary glazing - i.e. some have come of their runners, some don't close properly. They run 2/3 the height of the room and 80% of wall area. So should be huge heat loss.

Surely this heat can't just be the PC's/monitors and body heat? It's worse in the mornings, until we come in and open the windows :-(

My hunch is that as we're on the 6th floor it's simply heat rising from lower floors. Is this a common problem? If so I dread to think what it will be like May-August :-(

More importantly - how do you solve this assuming your employer isn't planning to move? Get the floor insulated and pass the problem down to the storey below?

Turn the computers off overnight? Leave some windows open a crack?

Are you on the top floor?]]> No apparent heating but overheating in winter? http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3645&Focus=49015#Comment_49015 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3645&Focus=49015#Comment_49015 Thu, 26 Feb 2009 14:31:07 +0000 unguided1 regards

I work in a 60's building and one side (south facing) gets extremely hot while the other (north facing) stays cold. Even in summer the north side sometimes needs heating.
If your building has an east or south east facing side with no obstructions then it is quite possible that along with rising heat there is an element of solar gain. This will be made worse by the low U-Value of the construction allowing the heat to transmit faster into the working area.

The high degree of prefabrication and the avoidance of long drying times lead to quick progress in construction and thus an especially high level of efficiency. In striving to optimise the mass and dematerialisation of the building components, in addition to various practical and economic advantages, one problem, namely a loss of thermal mass and the negative impacts on the indoor climate arises.
