Easy-to-use Tools Make Code Compliance Quick and Seamless
American Wood Council apps streamline code compliance for interiors and exteriors.
- The Energy UA Calculator: The Energy UA Calculator computes an opaque wall or fenestration U-factor based on the Total UA alternative compliance method permitted by the International Code Council’s 2012 International Energy Conservation Code (IECC) or International Residential Code. The U-factor indicates the rate of heat loss of a wall assembly. The lower the U-factor, the greater a wall's resistance to heat flow and the better its ability to control heat loss. This new Energy UA Calculator is consistent with AWC’s Design for Code Acceptance (DCA) 7, “Meeting Residential Energy Requirements with Wood-Frame Construction.” DCA 7 and the accompanying app provide ways to economically meet the residential energy requirements of the 2012 IECC. The app also gives insulation requirements needed in various wood wall assemblies to achieve the specified opaque wall U-factor.
- The Span Calculator: The Maximum Span Calculator for Wood Joists and Rafters performs calculations for all species and grades of commercially available softwood and hardwood lumber as found in the National Design Specification (NDS) Supplement. Common uniform loading conditions are available and adjustment factors for wet service conditions even allow calculation of deck joists. The "span options" calculator allows selection of multiple species and grades for comparison purposes.
