Remember Jimmy the witch, plumbing store keeper in CIT ?
PS. I'm talking 27 years ago. I spent more time in SR. HENRYS with him than in class.

Was he a biker dude with a ZZ top beard? Richard Crowley ( RIP) was the instructor I had ..sound man he was.

Athlone 2003...Charlie 's for a pint of soup.....im mean a pint with your soup I think, there was no talk of resession in them day's.

What was the lecturers name, the Dublin guy had a beard he was head buck cat when I was there, he was always looking for a lift home to Dublin on a Friday evening. Good guy though and great times.

He's the only instructor i can remember from there , I don't know if its because its 10 years ago or the fact that the amount of beer consumed killed my brain cells ..... I wonder are any of the houses in willow park still standing.

Yea pat that's right, used to let us were our hoodie up in class, something about if we were insulated our necks and kept warm we would learn more. Loved telling the story bout his roof snow not melting before all his naighbours cause it was so well insulated.

Rob...the badger formally known as, sound guy seen him other day at the tullamore show.

Haha , I got lost going into the estate after a night out , had to park my car further down the road from the house earlier in the day as road was full of cars, came home from the session , couldn't remember where the house was , staggered up and down the road pressing the central locking button on the car keys trying to follow the flashing indicators , best nights sleep down there and it was in the car

Can any explain this equation

Not an expert in any of this building energy calculations....but Equations interest me for Mathematical reasons.
Have a look at :

http://www.cedengineering.com/upload/Heat%20Loss%20Calculations%20and%20Principles.pdf

also DD appear to be Degree Days.... see Met Eireann website

http://www.met.ie/climate/degree-day.asp

and also:

http://www.guntermannengineering.com/images/A%20Simplified%20Degree%20Day%20Method%20for%20Commercial%20and%20Industrial%20Buildings/scan.pdf

Hope these help.

Excellent, well done. That's a good explanation of DD @ average of 15.5C.

OK, so what I make from it is:
E heating = Overall kw demand required
Q heating = Overall collective heat loss of the building, as a U value
T Ai = Inside air design air temperature (commercial given as 18C)
T Ao = Outside air temperature (given as average outside temp, lowest + highest / 2)
DD = 18C
Correction Factors = 1 for full use or percentage of 1 for partial use
N seasonal = Seasonal efficiency of the building (a separate calculation)

Well done Braka
