ATLANTA, GA —The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has released a new CD toolkit designed to enable users to determine load calculations more easily with 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 toolkit contains chapters on building heat balance, environmental conditions, solar radiation, transient heat conduction through the building envelope, convective heat transfer, infiltration and ventilation, internal gains, and general utilities.
