9 What is ENERGY STAR? The national symbol for environmental protection through energy efficiency, recognized by more than 85% of all U.S. households A government-backed, voluntary program that helps businesses and individuals protect the environment through superior energy performance by providing energy-efficient solutions for homes, businesses, and institutions

10 ENERGY STAR Programs Products Certified Homes Multifamily High Rise Commercial Buildings and Plants

11 ENERGY STAR Residential Programs Guidelines apply to new or gut rehab: Single Family Homes (detached and attached) Factory Built Homes (manufactured and modular) Low Rise MF Residential Buildings Mid and High Rise MF Residential Buildings Buildings previously ineligible for ES Homes Launched in June 2011 Certified Homes MFHR

12 ENERGY STAR Residential Programs Eligibility ENERGY STAR Certified Homes, v3 All Multifamily buildings with 3 stories or 4 units; and 4 and 5 story multifamily buildings with heating, cooling and DHW separate from other units, and less than 20% residential associated common space ENERGY STAR Multifamily High Rise 4 and 5 story buildings with either Heating, cooling and DHW separate from other units, and more than 20% residential associated common space Central heating, cooling, and/or DHW All buildings with 6 stories

13 ENERGY STAR Commercial Buildings and Plants Recognition for superior energy performers Achieve Score of 75 or above (Multifamily score available as of September 16, 2014, for existing multifamily properties) Meet industry standards for indoor environmental quality Awarded each calendar year Buildings must re-apply annually Properties must have 20+ units and ALL bills 1 to 100 Score National Average Earn ENERGY STAR

14 Why pursue ENERGY STAR? = Energy Efficient Affordable Comfortable Durable Financing/Incentives Recognition

23 ES MFHR Certification Process Enter Developer Enter Partnership Agreement Project Application Design Prerequisites Energy Modeling Proposed Design Submittal Build Earn the ENERGY Earn STAR Perform

24 Proposed Design Submittal (Pre-Construction) Model output summary that shows at least 15% TDV energy savings compared to 2013 Title 24 ENERGY STAR MFHR Prerequisites Included in construction documents Documented using T&V Excel file Validation Form Signed and stamped by Licensed Professional

25 ES MFHR Certification Process Enter Developer Enter Partnership Agreement Project Application Design Prerequisites Design Energy Modeling Proposed Design Submittal Build Build to design Testing and Verification As-Built Submittal Earn the ENERGY Earn STAR Perform

26 Testing and Verification Protocols Ensure proper energy conservation measures installation Identify often-overlooked details that have a critical impact on efficiency, comfort, quality, & durability Identify and correct mistakes before they become problems ES MFHR includes some inspections/tests that may not be required by 2013 Title 24 or CMFNH

27 Testing and Verification Protocols 1. ENERGY STAR Certified Appliances 2. Domestic Water Heating (Central or In-Unit Systems) 3. Envelope Construction/Insulation, R-value/U-value/SHGC 4. Garage 5. Heating and Cooling (Central or In-Unit Systems) 6. Lighting (In-unit, common area, exterior, controls) 7. Pump Motors 8. Air-sealing and testing; Ventilation and testing 9. Metering

28 Testing and Verification Worksheets A central file to store/share building information with all members of the design team Document results of plan reviews, inspections, verification, and performance testing Organized for use in the field Submit Excel-based worksheets to ES MFHR Prior to construction to document results of the plan review After construction is complete, to document the results of testing and verification.

29 As-Built Submittal (Post Construction) Update energy model with as-built conditions Test and verify energy conservation measures Measures meet ENERGY STAR MFHR Testing and Verification Protocols Document results in Testing and Verification Worksheet Provide photo documentation in Photo Template Provide Validation Form Signed and stamped by Licensed Professional
