Heat load rules of thumb
Heat load rules of thumb
(OP)
Here is an easy question compared to some that have been asked. The question is...what BTU per sq. ft. of heating should I expect to be needed for a "typical" office building. Wall construction is fairly old but the windows will be new.
Thanks for your help

I wouldn't know what a typical office building is anymore. It changes constantly! With the shift to LCD monitors and Energy Star computers, a huge chunk of load is disappearing from the typical cubical jungles that sprouted in the 90's. Add in the shift to T8 lighting, reduced ventilation schemes, more changes in load on both sides of the equation. What climate are you concerned with? Rules of thumb I've seen (in books like Art Bell's) have a range with the upper boundaries 50% above the lower.

Rules of thumb are good for a preliminary ballpark estimate, or as a load check figure.
Take the "V" out of HVAC and you are left with a HAC(k) job.

From that guideline, a general office environment was listed as 300-400 sqft/ton but that number truly should only be as an estimate or as a check number to the load calc.

If rules of thumb would suffice, Engineers would not be required.
