Passive heat from building operations
Passive heat from building operations
(OP)
Hi Everyone,
This is my first thread on eng-tips. I am hoping one of you can point me in the right direction here.
I am putting together savings calculations for various energy conservation measures. I am working on a calc in which i need information on the passive heat (latent heat) given off by building occupants and other heat generation outside of a buildings hvac system.
Where can i find this information on a btu/h*ft^2 basis? I need this information for manufacturing facilities, schools, office buildings etc. As many different types of buildings as i can get would be great.
Thanks in advance.

google engineering toolbox, you can find lot of useful data there.
RE: Passive heat from building operations
Attached is the Cal Title 24 alternative calcs manual, there is a nice table in section 2 for what you seek. It also contains a lot of good energy modeling information.
If I get a chance, I'll post some more resources for you in this thread. I have an extensive library, but not a lot of time today.
Best to you,

Oh, and it's a freebie. http://comnet.org is where I got it.
Others: NREL, DOE, PNNL
More next week.

I will take a look at what you guys posted up for me. Much appreciated!
RE: Passive heat from building operations
In that appendix B from COMNET, it lists the btu/occupant. How do you translate that to a rate over time.
As an example, it lists for Dining General, 275 btu/occ.

RE: Passive heat from building operations
for exapmle what if someone told you: it is between 10 to 20 Btu/hr.ft2, the other told you it betwwen 15 to 25 btu/hr.ft2
RE: Passive heat from building operations
317069, i understand these are just rules of thumb, and are not concrete rates. Do you have a suggestion on how to improve the accuracy of these estimations? Or is it something that just comes with experience?

I appreciate all of the responses, and help i have gotten.
It looks like eng-tips will be a great resource for me.
Thank you all.
