Heat Loss

L Thiesen

How do you figure a heat loss for a room in a basement? I looked at the Slant Fin program but I couldn't figure out how to use it. Thanks

Do you just need the basement or the whole house?
You need to know about the wall construction, insulation of walls and floors, and how much of your walls are below and above grade.

We are planning to finish a room in our basement to be used as a guest bedroom. The walls and floor are bare concrete now so we are starting from scratch, only about 12 to 15 inches of the walls is above grade. No insulation on the walls or floor at this time.

You need to know the construction of the finished room. Framing, insulation, windows, etc.
Go back to the Slant/Fin calculator and play around with it. It has drop down menus in each category.

Also, most areas regarding living space below grade, especially a bedroom, require proper egress. You may be doing this on your own, with or without permit, but make sure you meet that requirement for egress.

That's the problem, I cant get beyond the first step where you enter a job name. It will not let me do anything else, I do not understand what to do next.

The exposed wall factors for a below-grade wall, at least on the PC version, are under the poured concrete option. Also, the floor factor for a below-grade floor is under concrete as well.

But you can't enter anything until you define the job- that's what creates the job file.

Thanks guys, came up with a number. Sort of a guess but its a start.
