In January, NRCA, with the support of the Polyisocyanurate Insulation Manufacturers Association, released RoofWise—Version 2.0, an updated version of the CD-ROM software that analyzes the energy efficiency of low-slope roof assemblies. RoofWise will be a useful tool for those who design or specify low-slope roof assemblies.
RoofWise originally was developed and released in 1998 as a PC-based software application version of NRCA's energy-analysis publication, The NRCA Energy Manual. RoofWise offers a significant advantage compared with the manual because it automates the lengthy calculation procedures necessary to determine minimum thermal insulation requirements, building heating and cooling costs, and proper vapor retarder placement.
As a result, roofing professionals can analyze multiple roof assembly configurations in a fraction of the time it would take to manually calculate the results for a single roof assembly configuration.
