3 Enforcement and Compliance (cont.) Q: Do jurisdictions have to enforce the code? A: If municipality or county requires a permit for construction, additions, alterations, renovations or repairs to existing construction Absolutely, YES! Q: What if jurisdictions do not regulate energy efficient construction? A: If a unit of local government does not regulate energy efficient building standards, any construction, renovation or addition to buildings or structures is [still] subject to the provisions in the Act.

4 Application to Home Rule Units Q: Can jurisdictions amend the code? Commercial: Not in a manner that is less stringent than the code established in the EEB Act. However, nothing in the EEB Act prevents adoption of a [commercial] energy code that is more stringent. Residential: Not in a manner that less or more stringent than the code established in the EEB Act. The following may regulate using more stringent standards If adopted d 2006 IECC on or before May 15, 2009; and provided CDB with identification of adoption as required by 55 of Illinois Building Commission Act; or The City of Chicago

5 Enforcement and Compliance (cont.) Q: What do I do if I am a designer, contractor or home builder conducting work w/in the scope of the code in a unit of government that neither inspects for nor regulates energy efficient construction? A: If a unit of local government does not regulate energy efficient building standards, any construction, renovation or addition to buildings or structures is [still] subject to the provisions in the Act. Recommendation: Evaluate your risk exposure?

6 6 Why Building Energy Codes?

8 U.S. Commercial Energy Code History of efficiency i improvements

9 30% Improvement over 2006 IECC; 2012 vs Commercial The bottom line Equivalent savings to ; Must select an additional efficiency package: Efficient lighting system, Purchase higher efficiency HVAC equipment, or Design for on-site renewable energy at least 0.5 W/ft 2 ; Continuous air barrier requirement for most buildings; Cool/High albedo roof requirements for Chicago only; Manual daylighting controls for buildings seeking 30% < WWR 40%; Skylights/daylighting for large (>10,000 ft 2 ) spaces w/ tall (15 ) ceilings; Equipment efficiencies higher, energy recovery in more applications; Cx required where HVAC 40 tons cooling and 600 Kbtuh heating; Functional performance testing (Cx) for LTG systems; and Updated reference to ASHRAE

10 2010 vs The bottom line 30% Improvement over Change to Title, Purpose, Scope to address process (plug, data) loads; Process cooling (data centers) now addressed; Continuous air barrier requirement for most buildings; Cool/High albedo roof requirements added for Zones 1-3; WWR 40% w/ South-facing glass area > West-facing, > East-facing Skylights/daylighting for large (>5,000 ft 2 ) spaces w/ tall (15 ) ceilings; Automatic daylighting controls required in most spaces; Equipment efficiencies higher, energy recovery in more applications; VRF systems added; New term (IEER) for unitary focus on part-load; Plug load control for half of all receptacles in certain spaces; Exterior lighting power allocated by Zoning; and LEED Appendix G is not a compliance path.

22 C Roof Reflectance and Emittance Roof Reflectance and Emittance Required for Zones 1-3 Chicago Urban Heat Island? Buildings with low-sloped roofs (< 2:12), directly above cooled, conditioned space shall meet one of the following: Initial solar reflectance index of 82, or 3yr-aged reflectance 0.55 and 3-yr aged emittance 0.75, or Initial reflectance of 0.70 and initial emittance of 0.75, or 3yr-aged reflectance index 64, or in lieu of cool roof, or 90.1 allows increased roof insulation levels, in lieu of Cool Roofing. Exceptions vary!

23 Heat Wave Chicago 1995 Chicago felt tropical, like Fiji or Guam but with an added layer of polluted city air trapping the heat After about forty-eight hours of continuous exposure to heat, the body's defenses begin to fail. So by Friday, July 14, thousands of Chicagoans had developed severe heat-related illnesses. ~ Eric Klinenberg, author of Heat Wave: A Social Autopsy of Disaster in Chicago

Construction where the existing roof, wall or floor cavity is not exposed. 5. Reroofing [[See Roof recover and Roof replacement. ]] for roofs where neither the sheathing nor the insulation is exposed. Roofs without insulation in the cavity and where the sheathing or insulation is exposed during reroofing shall be insulated either above or below the sheathing IECC Update 26
