I see Queen's building has been "in the red" (and yellow) for a almost 2 weeks now. The faces greeting us on the big screens have been decidedly glum. There seems to be a data "blip" 25-27 Feb, but apart from that it does seem that we're in the red zone a lot of the time.
On Gas in particular: Given that the model accounts for outside temperature - I wonder has the set point on the building been increased? Certainly my room (1.11) feels too hot by the end of the day - it's about right when we arrive in the morning. Maybe this is related to Paul's open window question..... Possibly also my question about the heaters here - my deduction from the answer by @DMU_Energy here is that the set point for the public areas is now 21 deg C. This is very hot - I expect it was previously much cooler.

The aspiration behind the university creating the breakout spaces within the Queens Building concourse was to provide areas where students could meet, relax, work, etc. Therefore these are no longer circulation spaces, they are treated in the same way as classrooms, offices, etc. Therefore, in line with CIBSE guidance, the space is now heated to 21 degrees. Before this project took place, apart from the radiators on the wall as you enter the concourse, there was no heating in this area. Therefore, the Queens building will use more gas as we are now treating a much larger space. Has anyone shut the windows yet?

Hi Paul - yes - didn't mean to imply they were being heated beyond the regulations. I realise what you meant was that they were re-classified and hence recommended to be hotter (whether I personally agree or not is another matter - but I realise that's what the docs say !). I guess what you say means that my deduction is right - as we're heating a larger volume to the hotter temperature, we're likely to be in the red on Gas for a long time to come... I guess the refurb, then, is one of the events that this system is designed to pick up.
In terms of our room (1.11) - I guess the problem is with a granularity of control? It feels hot to me, but I guess the heating is controlled based on the temperature in the main bit of the IESD space, which is probably about right.
Also - I can accept that maybe I just like it strangely cold.
I'll check the windows on the way out - I presume @PaulFleming closed them when he noticed them, but I'll check.

P.S. Just to complete this topic - I did check the windows were shut - they were with the exception of the big one at the top that I can't access. It's been shut for the last couple of days, though.
