2 History of Illinois Energy Conservation Code 2001 Chicago s first-ever Energy Code (2001 IECC) 2003 Illinois law requires Energy Code for State Buildings 2004 Public Act requires Energy Code for all Commercial Buildings 2006 Legislation requires Energy Code to be Most current version IECC 2009 Legislation adds Residential Energy Code Provisions (2009 IECC) 2012 Amended implementation of 2012 IECC to January 1, Likely implementation date for 2015 IECC, November 30, 2015 Destination Energy Savings 2015 Business Symposium

5 ASHRAE Standard (Illinois)» 23% Improvement over 2006 IECC/ ;» Change to Title, Purpose, Scope addresses process (plug, data) loads;» Process cooling (data centers) addressed;» Continuous air barrier requirement for most buildings;» Cool/High albedo roof requirements for Chicago only;» WWR 40% w/ South-facing glass area > West-facing, > East-facing» Automatic daylighting controls required based on daylit floor area;» Mandatory top-lighting for spaces >5,000 ft 2 w/ tall (15 ) ceilings;» Equipment efficiencies higher, energy recovery in more applications;» Plug load control for half of all receptacles in certain spaces;» Exterior lighting power allocated by Neighborhood Zoning; and» LEED Appendix G is not a code compliance path. Destination Energy Savings 2015 Business Symposium

6 Does my project need to comply?» All buildings other than One- and two-family dwellings; Townhouses; Condominiums, Apartment buildings, Convents/Monasteries, Sorority/Fraternity, Dormitories, Group Homes, Time shares, etc.; Three-stories or less in height (Four-stories or less in Chicago) Destination Energy Savings 2015 Business Symposium

7 Buildings or spaces considered exempt. Buildings otherwise exempt from provisions of a local building code; Buildings that do not contain conditioned space; Buildings that do not use electricity or fossil fuel for comfort conditioning; Historic buildings (i.e., Buildings with Landmark Status in Chicago) Destination Energy Savings 2015 Business Symposium

10 Low Energy High Value: The Value of Energy Modeling. Presented By: Nic Fonner, EMIT, LEED BD+C

11 82% Annual ~ $302,000,000,000 U.S. electricity expenditures - EIA

12 Ten reasons to pursue [energy efficiency] Does Green Pay Off? July 12, 2008 Summary of the financial benefits of ENERGY STAR labeled office buildings, National Technology Readiness Survey 2009 Kelly Global Workforce Index 1. Lower operating costs 2. More marketable 3. Reduced greenhouse gas emissions 4. Lease to federal tenants 5. Higher rental rates 6. Increased asset value 7. Manage risk when developing properties 8. Hedge against future mandates 9. Little to No cost (incentives) 10. It s just the right thing to do

13 Integrative Design Process 13

14 Where to Start 14

15 What is an Energy Model Energy Modeling predicts actual energy utilization.* *account for idealized test environment and the actual use and condition of the building The primary objective of Energy Modeling is to inform the decision-making process while recognizing trade-offs between different criteria. It is not to have the most thorough and detailed simulation. 15

16 Complexity 16

17 Why We Energy Model Code Compliance Beyond Code LEED Federal Mandates Incentives 17

18 Benefits/Responsibilities The effective use of energy modeling throughout the design process can empower the entire team in evaluating high performance designs.

25 Case Study: R.C.C. Center for Sustainability and Innovation Performance since October 2009 As of May 19 10:20 AM

26 Case Study: WBGL Radio Station Renovation & Expansion [Champaign, IL] Concept 1 MAX SITE DENSITY: Results in largest envelope area of any concept. This concept has the most energy consumption. Even with the increased surface areas, a large portion of the building cannot use daylight harvesting without the addition of skylight design. Concept 2 MEDIUM DENSITY & ATRIA: Results in an increased density with reduced envelope area and associated thermal loads. With the two atrium spaces and clerestory glazing, daylight harvesting potential is substantially greater than Concept 1. Concept 3 MAX DENSITY & ATRIUM: Results in a reduction of envelope area to 50% of Concept 1. This also leads to the least energy consumption of all concepts. However, initial daylight studies estimate a slight loss of potential for daylight harvesting than in Concept 2.
