A new CD toolkit from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) reportedly makes calculating load calculations easier through use of computer technology. ASHRAE Toolkit for Building Load Calculations contains the FORTRAN 90 source code needed for the new heat balance load calculation procedures introduced in the 2001 ASHRAE Handbook, Fundamentals. The information was developed as part of ASHRAE Research Project 987.
