Cooling and Heating Load Calculation Software
(OP)
guys, can you share what's HVAC load calculation software you are using and what's your comment and experience?
I'm looking for residential/commercial HVAC load calculation software that can use in USA and other country (ASIA, etc.)
appreciate your relpy. thanks!

manual 'N" for commercial from ACCA

It's the best program I've seen though, much simpler and easier to use than others mentioned. There residential programs are good too. They have worked out a lot of bugs in their latest release and their technical support is pretty good.

thanks

Now that we are doing simulations we also have Trane Trace 700 and that is all half our office uses now. I have more complaints with the simulation portion, but for loads my biggest complaints are how windows are input, it has no window type option, so each wall needs window are defined.
Trace has a nice 62.1-2004 ventilation rate calculation option that saves me time from having to do the calcs on a separate spreadsheet that we had to do when we only had Elite.

does HAP (Hourly Analysis Program)have cooling and heating load estimate for commercial and residential?
RE: Cooling and Heating Load Calculation Software
If you have any more specific questions about it let me know. I hope I answered your questions.
RE: Cooling and Heating Load Calculation Software
HAP (Hourly Analysis Program) is much more advanced, but is highly favoured with many of my consultants.
You can also design around different systems, and compare them.. (Splits, Pkg., CW, etc.).
Here's an overview that explains a lot for you: http://w

i read HAP feature and it didn't say it include Residential load calculation. I think its for Commercial only. Correct me if i'm wrong.
Also do you know if they have 30day trial?
Actually i'll use this for my PERSONAL use only. It's expensive though ($1,495)
thanks!

What is different about calculating the residential loads than commercial loads? I input my walls, roofs, windows the same. The lighting and occupancy schedules might be different, but I use HAP to calculate residential loads all the time. I'm not sure why a particular program that can calculate commercial building loads wouldn't be able to calculate residential loads.
Maybe you are talking about a systems analysis with residential type furnaces and stuff. I just model the system as a constant volume roof top unit in that case.
What else am I missing ?

i'm just waiting for HAP-Carrier support to give me a link to try their software (hopefully for 30days) before purchasing the full license.

this is sucks! carrier software support won't give me the link to download trial version of HAP without approval of their local carrier distributor....worse thing is the distributor is slowwwwwww....

PS. I normally use Carrier HAP for both residential and commercial load calculations. For quick energy modelling I use eQuest.

In MA you can download worksheets that allows you to input initial conditions and proceed step by step with the calculations. Once you understand the formulae, than you can appreciate the value of such sofware.
Using these worksheets for resential,commercial and light industrial is a good place to start before embarking on larger projects.

Good luck.

Price is 50% difference. Since i will use this for my own, i guess System Design Load is good enough?

The MA State Building Code 780CMR sheet #760.22. Complementing is the REScheck Compliance Certificate 2003IECC. Additional info is 522 CMR 9.00.
This material goes back to the early part of 2000 however I don't believe much has changed.

Thanks.

If simulating Carrier chillers you can get chiller performance maps for the exact chiller from Carrier which makes life easy.
We also use IES software which is very capable but has a very long steep learning curve.
