REScheck-Web simplifies residential energy code compliance by automating trade-off calculations for the IECC and a number of state-specific codes. Calculation Procedure. Free Tools This is a sampling of tools that are used in our courses. Many sources apply, including the sun, equipment running, lights and body heat from occupants. David Brown was very thorough about collecting all the data needed to get the most accurate heat loss, heat gain, equipment and duct sizing. Allowed heat loss per meter of pipe is 80 W/m. Heat loss is reduced as the coverage of insulation progressively increases.
