Home My Public Portal Aboutresentation on Article #19, Stretch Energy Code, Massachusetts Green Communitiesand Brewster Community Network Forum March 21, 2019 What Is Green Communities (GC)? A Massachusetts Department of Energy Resources (DOER) program, created by the Green Communities Act of 2008, that provides financial grants, technical assistance and local support to help municipalities reduce energy use and costs by implementing clean energy projects in municipal buildings, facilities, and schools. 2 What Is Green Communities? Currently 240 Massachusetts cities and towns are designated as Green Communities. Including Provincetown, Truro, Wellfleet, Orleans, Harwich, Yarmouth, Mashpee, Tisbury and West Tisbury. Chatham, Dennis and Nantucket currently pursuing designation. Almost $2.2M of Cape and Islands grants to date. 3 Why Is GC Good For Brewster? Supports Article 33 of the 2017 Annual Town Meeting – “Resolution To Address Climate Change By Setting Goals And Supporting Green Aggregation”. Establishes goals and policies to reduce municipal energy use. Increases the energy efficiency of new construction in Brewster. Provides funding for Town energy efficiency projects. Initial designation funding estimated to be $150,000. Additional grants available up to $250,000 / cycle 4 What Does Brewster Have to do? Green Communities Qualification Criteria 1.Adopt as-of-right siting for Renewable / Alternative energy generation or R&D or manufacturing. 2.Adopt expedited permitting process for #1 3.Create an Energy Reduction Plan to reduce energy use by 20% in 5 years. 4.Adopt Fuel Efficient Vehicle Purchase Policy. 5.Minimize life cycle cost in new construction - adopt the Stretch Code. 5 Where Is Brewster In The Process? Qualification Criteria 1.Adopt as-of-right siting - 2.Adopt expedited permitting process - 3.Create an Energy Reduction Plan –In progress through Cape Light Compact and DOER grant 4.Adopt Fuel Efficient Vehicle Purchase Policy – Select Board action needed 5.Adopt the Stretch Code –On May Town Meeting Warrant 6 Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth7 Criteria 5 –Minimize Life Cycle Costs Require all new residential construction and all new commercial and industrial real estate construction to minimize, to the extent feasible, the life- cycle cost of the facility by utilizing energy efficiency, water conservation and other renewable or alternative energy technologies. The DOER recommended way for cities and towns to meet this requirement is by adopting the BBRS Stretch Code (780 CMR 115.AA) an appendix to the MA State Building Code. •In a town, the Stretch Code must be adopted as a general bylaw by its Town Meeting. •https://www.mass.gov/files/documents/2018/08/10/guidance-5- criterion.pdf Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth8 Stretch Code Communities Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth9 Stretch Code •The Stretch Code ONLY applies to: •NEW residential construction and •NEW commercial construction > 100,000 sq. ft. or > 40,000 sq. ft. for conditioned spaces = Labs & Supermarkets •Additions, Renovations & Repairs are EXEMPT from the Stretch Code Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth10 The Stretch Code is No Longer Much of a Stretch •Base Energy Code (IECC 2015) and Stretch Code adopted by Massachusetts on 1/1/2017 •Current Base Code allows builders two options for residential and commercial new construction: Prescriptive •Checklist of Compliance Measures •Inspections During and Post Construction Performance •Pre & Post Construction Energy Modeling •Inspections During and Post Construction Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth Prescriptive •Checklist of compliance measures •Inspections during and post construction 11 •Major differences between the Base & Stretch Code are: •Removal of the prescriptive path option •HERS Rater needs to provide an Energy Model. •The cost to perform the modelling required by the Stretch Code can be covered by utility incentive. The Stretch Code is No Longer Much of a Stretch Performance •Pre & Post construction energy modeling •Inspections during and post construction Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth12 What is a HERS Rating? (Home Energy Rating System) Annualized energy analysis Heating, Cooling, Water Heating, Lighting and Appliances…. On site power generation-renewable energy Reference Home Based on IECC 2006 Code (International Energy Conservation Code) Defined as 100 Points 1 percent change in consumption = 1 point HERS 55 means about 45% more efficient than reference home Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth Why Test Performance? Prescriptive codes don’t guarantee good installation, air and water tightness, or that thermal insulation is effective. Small air gaps can reduce insulation R- values by 50% or more. HERS Raters provide third party verification 13 Creating a Clean, Affordable and Resilient Energy Future for the Commonwealth14 What is the HERS Process? 1. Review Building Plans via Computer Energy Modeling 2. In-process inspections –First inspection • Duct tightness test (if applicable)* –Second Inspection (usually combined with 1st) • Insulation –Final Inspection • Blower door test* 3.
