heat loss calculation

Just what is heat loss calculation used for?
Is it just for sizing the boiler?
If so can I use a program that is for calculating forced air and baseboard heating.
Isn't heat loss calc, heat loss calc no matter what it is going to be used for.
I see that in one of the sticky's that it is mentioned about doing the heat loss calc. yourself. But doesn't mention what to use.

A heat loss calc can be used to size the radiation in a room, determine the heat loss at various outdoor and indoor temperatures, evaluate the impact of different insulation and envelope improvement options, and a bunch of other stuff.

There are websites that provide a means to do it, commercial software, etc.

The standard form of heat loss is known as a "Manual J" for the governing procedures as specified by ASHRAE.
