Using the Federal Trade Commission's energy model calculations to determine effective R-values for insulation material, as many designers do, is not realistic and can potentially lead to increased energy costs, poor indoor performance and mechanical equipment being oversized or undersized. Yearly average temperatures are available for many regions across North America and can be used to understand the temperature ranges expected for a location when determining the amount and type of insulation to use in a roof system.
In October 2014, NRCA Safety Consultant Bill Steinmetz and John Schehl, executive director of Roof Integrated Solar Energy Inc.,™ embarked on a 26-day journey through China to deliver a train-the-trainer program in partnership with the China National
Waterproof Association. Previous trips to China during the past 10 years had confined NRCA to conference centers and trade show booths. This trip allowed NRCA staff to learn and experience much more about the Chinese roofing industry.
