R value requirements are listed specific to wall type and climate zone.
Maximum area, maximum U values and SHGC are listed in table 502.3 (p. 32 IECC 2006)
Maximum 3% of surface specific U values for glass and plastic are listed in table 502.3 p. 32 (IECC2006)
5.5 m3/h.m2 at 75 Pa for curtain walls and storefront glazing
18.3 m3/h.m2 at 75 Pa for commercial glazed swinging doors and revolving doors
Space Heating System
Mandatory provisions for calculating heating and cooling loads, equipment size ratios, thermostatic controls and energy recovery requirements are prescribed
Performance efficiency requirements are prescribed using a mix of coefficients (SEER, EER, IEER, IPLV and AFUE) for listed types of systems. Design and controls including climate zone specifications are detailed (IECC 2006 pp.34-46)
Water Heating System
Equipment performance, temperature controls, heat traps, pipe insulation and pool systems are mandatory and prescribed
Lighting control systems are specified on pages 49-50 (IECC 2006)
lighting power densities for interior lighting power allowances are given for specific building usage zones on p.50 (IECC 2006)
Pools deriving >60% heating energy from site-recovered or solar energy are exempt from pool specific energy saving measures for prescriptive approach. On site renewables are excluded from annual energy calculations for performance modelling approach.
