Online Energy Calculators was created by Clark Ricks
Years ago, I ran a story in ICF Builder magazine about the various online energy use calculators, reporting that many HVAC profesisonals felt Manuals J and S and the ASHRAE Handbook of Fundamentals didn't account for the thermal mass, h insulation, and/or low air infiltration of ICF walls.

At the time, the U.S. Dept. of Energy's version was deemed one of the best alternatives, although it didn't include an option for ICF walls. ( www.ornl.gov/sci/roofs+walls/calculators/index.html .)

The Portland Cement Association (PCA) had an Excel-based software that takes into account the unique properties of concrete.

With the market as it stands today, what's the best tool for sizing HVAC systems and calculating energy usage for ICF homes?
