    1. 1. Building Codes Efficiency: What State of Texas and Texas Cities are doing and Can Do to Promote Energy Efficiency in New Buildings Cyrus Reed, Lone Star Chapter, Sierra Club 512-740-4086 [email_address]
    2. 2. Overview <ul><li>What are building energy codes? </li></ul><ul><li>What are greenbuilding codes? </li></ul><ul><li>Why do energy codes matter? </li></ul><ul><li>Texas state process: new codes announced </li></ul><ul><li>How Texas Compares </li></ul><ul><li>What are Texas Cities doing on New Buildings? </li></ul><ul><li>Future Codes: What Happened with the 2012 IECC </li></ul><ul><li>What the state is doing: SECO, PUC and TDHCA </li></ul><ul><li>What is possible in El Paso area </li></ul>
    3. 3. What Are Building Energy Codes? <ul><li>Model Energy Code amendment process occurs every three years </li></ul><ul><ul><li>State & Local Officials Vote for Final ICC Commercial & Residential Codes </li></ul></ul><ul><li>Guided by Model Energy Codes, State and Local Codes are then adopted and administered, enforced by Local Officials </li></ul><ul><li>Green Building Codes are codes or programs that go beyond these minimum codes, often with financial or non-financial incentives for developers </li></ul>
    4. 4. Green Building Standards <ul><li>LEEDs </li></ul><ul><li>Global Green </li></ul><ul><li>Others, like Dallas/North Texas Green Building Standards </li></ul><ul><li>Homebuilders Green Home Standards </li></ul><ul><li>Energy Star homes (15% above base codes) </li></ul>
    5. 5. Green Building Aspects: water and renewables <ul><li>Water conservation requirements can be included like rainwater harvesting, low-flush toilets, low water-use fixtures </li></ul><ul><li>Renewable aspects – solar water heaters, solar-ready homes, solar PV homes, geothermal heat pumps </li></ul><ul><li>Recent California Codes good example with both mandatory and voluntary measures </li></ul>
    6. 6. Overall Benefits of Stronger Building Energy Codes? <ul><li>Save energy, stabilize homeowner & business costs, fewer utility shut-offs </li></ul><ul><li>Delays need for new municipal power plants </li></ul><ul><li>Quality homes/buildings = improved comfort, health </li></ul><ul><li>Generate immediate positive cash flow to building owners & occupants </li></ul><ul><li>Because buildings last for decades, improvements benefit future generations </li></ul><ul><li>Moves America closer to energy independence </li></ul>
    7. 7. Texas Air Quality Challenges
    8. 8. <ul><li>Measurable Benefits of Green Buildings </li></ul><ul><li>26% less energy consumed 1 </li></ul><ul><li>33% fewer greenhouse </li></ul><ul><li>gas emissions 2 </li></ul><ul><li>13% lower maintenance costs 3 </li></ul><ul><li>8%-9% lower operating costs 4 </li></ul><ul><li>7.5% increase building value 5 </li></ul><ul><li>3.5% increase occupancy ratio 6 </li></ul><ul><li>7.9 million jobs over next 4 years 7 </li></ul>

    12. 12. Texas State Process: Last 10 Years <ul><li>77th Legislature adopts energy codes from 2001 IRC for Single-family and 2001 IECC for all other construction in non-attainment areas </li></ul><ul><li>Energy Efficiency legislation (HB 3693) of 80th Session, established review process for ESL and SECO to raise minimum codes; </li></ul><ul><li>SECO and ESL take no action on 2003 or 2006 Codes </li></ul><ul><li>ESL recommends adoption of 2009 Codes in September, 2009 </li></ul><ul><li>June 4, 2010 -- SECO adopted 2009 IECC and 2009 IRC, with April 1, 2011 effective date for IECC and January 1, 2012 for IRC </li></ul>
