Question - Load calcs for existing large buildings
Looking for some insight from anyone who has experience with this. We all know the correct way to size hydronic boilers is to perform a proper load calc.
When it comes to very large buildings, how do you go about accomplishing that? Are their companies you can hire to do it? Is it costly? Is it possible to find original design info for the building anywhere?
I've been to a few Carrier system design classes. They suggested using "check figures" to estimate loads and in a worst case scenario it could be accurate enough select equipment. I need to find some load calc classes to attend.
I may have a project coming up for a large-ish building. It currently has three 2 million btu Aerco Benchmark condensing boilers that need to be replaced. I have not had a project of this size before where I might be part of the design. I work on and service equipment of this size and much larger every day, but never participated in load calcs. Any advice appreciated.
Never stop learning.
