Session 5A - Cyrus Reed Session 5A - Cyrus Reed Presentation Transcript

  • 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]
  • Overview
    • What are building energy codes?
    • What are greenbuilding codes?
    • Why do energy codes matter?
    • Texas state process: new codes announced
    • How Texas Compares
    • What are Texas Cities doing on New Buildings?
    • Future Codes: What Happened with the 2012 IECC
    • What the state is doing: SECO, PUC and TDHCA
    • What is possible in El Paso area
  • What Are Building Energy Codes?
    • Model Energy Code amendment process occurs every three years
      • State & Local Officials Vote for Final ICC Commercial & Residential Codes
    • Guided by Model Energy Codes, State and Local Codes are then adopted and administered, enforced by Local Officials
    • Green Building Codes are codes or programs that go beyond these minimum codes, often with financial or non-financial incentives for developers
  • Green Building Standards
    • LEEDs
    • Global Green
    • Others, like Dallas/North Texas Green Building Standards
    • Homebuilders Green Home Standards
    • Energy Star homes (15% above base codes)
  • Green Building Aspects: water and renewables
    • Water conservation requirements can be included like rainwater harvesting, low-flush toilets, low water-use fixtures
    • Renewable aspects – solar water heaters, solar-ready homes, solar PV homes, geothermal heat pumps
    • Recent California Codes good example with both mandatory and voluntary measures
  • Overall Benefits of Stronger Building Energy Codes?
    • Save energy, stabilize homeowner & business costs, fewer utility shut-offs
    • Delays need for new municipal power plants
    • Quality homes/buildings = improved comfort, health
    • Generate immediate positive cash flow to building owners & occupants
    • Because buildings last for decades, improvements benefit future generations
    • Moves America closer to energy independence
  • Texas Air Quality Challenges
    • Measurable Benefits of Green Buildings
    • 26% less energy consumed 1
    • 33% fewer greenhouse
    • gas emissions 2
    • 13% lower maintenance costs 3
    • 8%-9% lower operating costs 4
    • 7.5% increase building value 5
    • 3.5% increase occupancy ratio 6
    • 7.9 million jobs over next 4 years 7
  • Energy Efficiency – 2x Benefit
  • EE/RE Air Quality Benefits Source: Texas A&M, Energy Systems Laboratory – eCalc 2006
  • Importance of Building Energy Codes, Pocket-Book Issue
    • The adoption of statewide minimum energy conservation codes in 2001 led to an average of 17% decrease in electricity demand ($245) in new homes according to ESL
    • The City of Austin adoption of 2009 IECC codes with local amendments found that average homeowners would save over $225 a year over 2006 codes according to Austin Energy
    • While new codes do increase cost of housing, overall savings compared to increased mortgage payments are four to one ratio
    • Economic development strategy to create local jobs
  • Texas State Process: Last 10 Years
    • 77th Legislature adopts energy codes from 2001 IRC for Single-family and 2001 IECC for all other construction in non-attainment areas
    • Energy Efficiency legislation (HB 3693) of 80th Session, established review process for ESL and SECO to raise minimum codes;
    • SECO and ESL take no action on 2003 or 2006 Codes
    • ESL recommends adoption of 2009 Codes in September, 2009
    • June 4, 2010 -- SECO adopted 2009 IECC and 2009 IRC, with April 1, 2011 effective date for IECC and January 1, 2012 for IRC
  • How Texas Compares: Residential
  • An ESL Chart
  • Notable Changes - 2009 IRC/IECC
    • Air sealing and insulation – demonstrated compliance
      • Testing option – blower door
      • Visual inspection option – approved independent party
    • Duct tightness tested at rough-in or post-construction
        • Exception: all ducts and air handler are in conditioned space
    • High-efficacy lamps in 50 percent of the permanent fixtures – CFL ’s qualify
    • Vertical fenestration
      • SHGC reduced from .40 to .35(IRC) and .30(IECC) in Climate Zones 2 and 3
      • U-factor reduced from .75 to .65 in Climate Zone 2, and from .65 to .50 in Climate Zone 3
    • Pool covers required for heated pools
      • Exception: solar heated (IECC)
  • The Texas Leaders
    • Frisco: Adopted Energy Star minimum for residential
    • Plano: 15% above 2006 Residential Green Building Program
    • Waco, Beaumont, Laredo, El Paso: Adopted 2009 IECC
    • El Paso also created greenbuilding task force to begin looking at additional changes and incentives
    • Corpus will adopt 2009 IECC next month
    • Austin: Adopted 2009 IECC with local amendments, plus Green Building Program plus Net-Zero Home 2015 Goal --
    • Houston: Looking at 5% above 2009 IECC as base code
    • Dallas: 15% Above 2006 plus LEED provisions beginning this year-- Already meets codes
    • San Antonio: Mission Verde and Adoption of 2009 IECC plus Green Building Program
    • Arlington: looking at 15% above 2009 IECC as standard
  • What codes have cities already adopted
  • Code Changes Submitted Code Development Hearing Public Hearing Results Printed & Distributed Code Changes Printed & Distributed Public Comments Sought on Public Hearing Results Public Comments Printed & Distributed FINAL ACTION HEARING New Model Code Published ICC 2012 CODE DEVELOPMENT CYCLE
  • Final Action Hearing on 2012 IECC
    • October 25-November 1, 2010
    • Charlotte, NC
    • Final proposal adopted makes 2012 IECC some 10% to 15% more efficient than 2009 IECC and 30% more efficient than 2006
    • eliminated Chapter 9 of IRC and replaced it with a reference to IECC -- eliminates the problem of differing codes
    • Final code was published in July of 2011
    • Energy Systems Laboratory in Texas will begin analysis of new code soon and make some determinations by December of 2011 or January of 2012
  • What Options do Texas Cities Have?
    • Adopt 2009 IECC or 2009 IRC by January of 2012;
    • Adopt 2009 IECC with local amendments to go above code
    • ESL has produced an analysis showing how to get 15% above the code
    • Consider other greenbuilding provisions related to materials, energy and water either as mandatory or as incentives coupled with Centerpoint or other programs
    • Adopt the 2012 IECC or have timeline for 2012 adoption today to give developers advanced notice
  • Other State/Local Action on Energy Efficiency
    • PUC adopting rules to increase investor-owned utility goal to 30% of growth in demand for energy efficiency by 2013 as part of SB 1125; El Paso Electric and others will have to expand EE offerings, including potentially incentives for greenbuilding
    • Legislature passed HB 1937 in 2009, which allows municipalities to loan out money for energy efficiency and renewable energy upgrades, paid back through property taxes HOWEVER STICKY LEGAL ISSUES –will need to be solved at federal level
    • SECO through stimulus has grants and loans for public building upgrades for EE and solar -- some $300 million in all
    • Churches and homes of worship added to SECO revolving loan program through 2011 legislation
    • TDHCA spending more than $300 million in weatherization dollars. Houston has some $25 million –
    • City of Houston doing Better Building Program for commercial
  • The Future? What is possible in El Paso Area?
    • Base Energy Codes for New Buildings – El Paso already adopted the 2009 IECC
    • El Paso also adopted a resolution to look at green building issues
    • Non-financial and possibly financial incentives for Buildings that go above code with water, materials, energy improvements
    • Setting up process for 2012 IECC adoption sooner rather than later
    • Continue to require municipal buildings to meet higher building code standards
    • Loan programs -- on-bill or property tax assessments -- for existing buildings to upgrade;
    • Solar-ready requirements for new homes with ultimate goal of making zero-net energy homes
    • Robust solar PV and hot water incentives offered at local and state level such as third-party ownership, net-metering, and potentially performance-based rebates for new and old buildings.
