Single glazing - HVAC & base board heating
Single glazing - HVAC & base board heating
(OP)
Hi,
Im am involved in the design of HVAC system for an old building which is being turned into an office. The perimetre of the building has 3 metres high glass, single glazing. Will my conventinal ducted air system deal with the perimetre heating load in winter if sized big enough or will I alwys have a problem with down drafts in winter (-3deg C) unless I install base board heating.
Double glazing is never a problem but i remember seeing an old building long ago with conventional HVAC plus base board heating.Why would they have done this?? Please help>>

RE: Single glazing - HVAC & base board heating
You would have to check your space conditions to determine what is necessary.
RE: Single glazing - HVAC & base board heating
My advice is to fix the real problem in the first place and see if the glass can be replaced. If someone is spending a bunch of money on new HVAC and upgrading the building, then do your sums and see if the savings in the capital cost of the HVAC equipment plus the on-going energy savings and comfort improvements will offset the cost of installing better glass. The only impediment to that would be local Heritage folks who want to preserve the windows and frames.

If the window is single glazed, it is old.....if it is old, it leaks cold air like a sieve. As already mentioned, keeping the radiant temp of the wall up keeps occupants comfortable.
It is always the best idea to add heat where you are loosing it for comfort....at the outside wall and window.
RE: Single glazing - HVAC & base board heating
When you say put radiation under the windows, what kind of mechanical radiator product provides this. We would be looking at electric type, any web sites you know off just to give me an idea?
Also how do you size them? are they for the full heat loss load of just part of it?
