  • Submit to Professor/ Kelly by Tuesday evening
  • Most of the Life Cycle Cost is put into Heating and Cooling. In New England this is an important factor because of the freezing temperature in winter and oscillating hot summers.
  • Prescriptive- Specified brand names for materials and methods for execution well defined.Performance-Define performance of end result and identify testing methods
  • The current IECC 2009 Building Code performance requires a HERS rating of 100 or lower. Energy Star Program provides builder incentives and rebates like $1250 per home for HERS 65 index, and on appliances, fluorescent light etc.

  • Transcript of "Stretch Building Code"

    1. 1. Stretch Building Code Green Communities ActJennifer Henriquez • Deborah Silva • Joe Szafarowicz
    2. 2. Green Communities Act• Ambitious energy legislation passed in 2008• First state in the US to pass something like this• Creates the Green Communities Program
    3. 3. Green Communities Program• There is $10 million per year in funding to towns & cities• Consists of 5 Criteria –All these requirements aim to reduce energy consumption –At a commercial, residential, and municipal level
    4. 4. The Five CriteriaCriteria 1: As-of-Right Siting – Renewable Energy/Alternative EnergyCriteria 2: Expedited PermittingCriteria 3: Energy Base Plan/ 20% Energy Reduction PlanCriteria 4: Purchase only Fuel-Efficient VehiclesCriteria 5: Minimize Life-Cycle Costs Adoption of “The Stretch Code”
    5. 5. Green Communities Sutton Millbury• July 19, 2011 • July 19, 2011 • $143,050 • $167,025
    6. 6. Green Communities Marlborough • December 16, 2010 • $217,125• To fund energy conservation measures at several municipal buildings, a hybrid vehicle, a site evaluation for a solar PV system, and to fund an Energy Efficiency Manager position
    7. 7. Green Communities Palmer • May 25, 2010 • $169,103• To fund energy conservation measures at Town Hall; a boiler and chiller replacements
    8. 8. The Stretch Code• An appendix to the Massachusetts Building Code• 780 CMR Appendix 120 Stretch Energy Code• Targets largest uses of energy in buildings – Heating, appliance usage, lighting, etc.• Purpose – reduce energy use in buildings by roughly 20%

    11. 11. Test Performance • Prescriptive codes don‟t guarantee good installation, air and water tightness, • Air gaps can reduce effective thermal insulationImage Source: Environmental Protection Agency
    12. 12. Home Energy Rating System (HERS) • Stretch code: performance – 70 or less <3,000 sq ft. – 65 or less >3,000 sq ft. • Used by the Housing Mortgage Market to value homes • Requires a certified HERS rater • RAM software • Energy Star Program
    13. 13. Residential New Construction• Performance only „stretch‟ option – Uses Home Energy Rating System (HERS) – 70 or less < 3,000 sq ft. – 65 or less > 3,000 sq ft.• Requires a certified HERS rater – Review building plans – Check insulation installation – Blower-door and duct testing – Thermal bypass Checklist
    14. 14. Residential Additions• 2 options – Performance or Prescriptive – HERS index on just addition (often not possible) or whole house – Treated as new construction – 70 or less < 3,000 sq ft. – 65 or less > 3,000 sq ft.• Most Additions will use Prescriptive Path – Energy Star Builders Option Package (BOP) – Includes Thermal Bypass Checklist
    15. 15. Commercial ‘Stretch’ Appendix• Only for New Construction over 5,000 sq ft• Performance option for all Buildings• Utility program & incentives to help• Prescriptive option includes 3 choices – Heating and cooling equipment improvements, – Improved Lighting efficiency (LPD) – 3% + of electric needs from on-site renewable
    16. 16. Town Benefits• Stretch Code is an optional appendix to IECC 2009 code – Once IECC is updated, stretch code will be integrated• Promotes Energy Efficiency & Collaboration – Gives flexibility to both builders and homeowners – 20-35% energy reduction provides savings in utility bills – Promotes awareness of sustainability
    17. 17. Town Benefits• Opportunity to apply for grants – Can use grant to install energy-efficient appliances and/or systems – Grants will be competitive in the future• Publicity – Society is turning more green – “Green Communities” status a noticeable factor for Charlton
    18. 18. Incentives for Homeowners• Long-term energy savings – Higher upfront costs, but reduction in utility bills – Energy Star utility sponsored savings: National Grid, NSTAR, etc. – Larger structure = More proportionate savings• Tax incentives and credit – Up to $1,250 for homes with HERS of <= 65 – $2,000 in Federal tax credit
