  1. ENERGY STAR Certified Homes 101 Jennifer James, ICF International on behalf of EPA March 12th , 2013

  2. What you will learn • Basics of ENERGY STAR • The new value of an ENERGY STAR certified home. • The sales support that ENERGY STAR brings to building partners. 2

  3. The Value of ENERGY STAR 3

  4. ENERGY STAR Certified Homes Build Better Homes Sell More Effectively 4

  5. How to build better homes Build Better Homes Core Efficiency Measures System Inspection Checklists 5

  6. Core efficiency measures • Guarantees that efficiency measures are included in every certified home. • Prescriptive Path • Performance Path Core Efficiency Measures 6

  7. System inspection checklists • Enable a “systems” approach for every certified home. • Set standards for often-overlooked details that have a critical impact on efficiency, comfort, quality, & durability. • Reflect 15 years of experience from EPA, researchers, industry, and thousands of partners. System Inspection Checklists 7

  8. Mix and match 8

  9. The risk of incomplete systems 9

  10. Value of a Complete Thermal Enclosure System 10

  11. Why Complete Thermal Enclosure System? 1 • A well-insulated and air-sealed home, with good windows and doors, reduces the amount of energy needed to keep the home comfortable. Thermal Enclosure System 11

  12. Thermal Enclosure System Checklist • Less than two pages, verified by the Rater. • Benefits: • Reduction in hot/cold spots. • Less heating and cooling energy. • Potential for HVAC downsizing. 1 Thermal Enclosure System Checklist 12

  13. FIBROUS NSULATION = AIR BARRIER Section 2: Quality-installed insulation • Defines minimum insulation levels and minimum installation standards Poorly installed insulation Quality-installed insulation 13

  14. Section 3: Fully-aligned air barriers Air barrier.. ..aligned with insulation Section 3: Often overlooked areas Section 3: Complete air barrier aligned with insulation 14

  15. Thermal enclosure system • In an ideal energy world… Space Constrained Area 15

  16. Section 1: High-performance fenestration • Defines U-value and Solar Heat Gain Coefficient requirements 16

  17. Section 4: Reduced thermal bridging • Addresses thermal bridging – places in the home where insulation is missing due to framing or space constraints. Studs conduct heat more easily than insulation 17

  18. Sections of the Thermal Enclosure System Rater Checklist • Section 1: High-performance fenestration. • Section 2: Quality-installed insulation. • Section 3: Fully-aligned air barriers. • Section 4: Reduced thermal bridging. • Section 5: Air sealing. 18

  19. Value of a Complete HVAC System 19

  20. Why a Complete HVAC system? • Heating and cooling equipment that is: • High efficiency. • Properly designed and installed. • Combined with a duct system that’s insulated, sealed, and balanced. • … maintains comfort with less energy. • Ventilation systems that remove low-quality air, provide outdoor air, and filter contaminants to improve indoor air quality. 2 Heating, Cooling, & Ventilation System 20

  21. HVAC system Checklists • Two checklists; one verified by Rater and one verified by the HVAC designer and contractor. • Benefits: • Less heating and cooling energy. • Improved comfort. • Improved indoor air quality. • Process control and quality assurance. 2 HVAC System QI Checklists 21

  22. Heating & Cooling Systems: Putting the “H” and “AC” in “HVAC” 22

  23. Basic heating & cooling system design • The amount of heat transfer can be quantified in British Thermal Units (Btu’s). • 1 Btu is approximately equal to the energy in a single match. 23

  24. Basic heating & cooling systems design • Adding & removing Btu’s impacts the temp. inside the home. 73F 72F 105F 24

  25. Three major steps to design an HVAC system 1) Calculate the heating & cooling load. 2) Select equipment to meet those loads. 3) Design ducts to get air from equipment to rooms, and then back to equipment, to offset loads. 25

  26. Step 1:Calculate heating & cooling loads • Cooling load is the maximum Btu’s added in one hour. 26

  27. Step 1:Calculate heating & cooling loads • Heating load is the maximum Btu’s lost in one hour. 72°F 35°F 27

  28. Step 2: Selectequipment that meets loads • Select equipment that removes Btu’s to meet cooling load. 72°F 73°F 72°F 28

  29. Step 2: Selectequipment that meets loads • Select equipment which adds Btu’s to meet heating load. 72°F 71°F 72°F 29

  30. Step 3:Design the duct system • Design ducts to properly distribute air through house. This offsets the loads. 30

  31. Value of heating & cooling systems • Two components of a complete system: Proper installation Proper design 31

  32. Value of heating & cooling systems • Diagnostic requirements of proper installation include the following tests: • Static Pressure test at the air handler. • Refrigeration test at the outdoor unit. • Electrical Amperage testing. • Duct blaster test. • Room Balancing Test. 32

  33. Ventilation Systems: Putting the “V” in “HVAC” 33

  34. Value of mechanical ventilation & indoor air quality • Consumers place value on indoor air quality. • Shouldn’t have to sacrifice for energy efficieny This home has low-quality indoor air! This home has high-quality indoor air! 34

  35. EPA’s Indoor airPLUS program • Indoor airPLUS is a complementary label for ENERGY STAR certified homes. • It addresses consumer demand for healthier indoor environments and offers comprehensive protection against harmful indoor air pollutants - the ‘Gold Standard’ for indoor air quality in new home construction. • Indoor airPLUS specifications include contaminant controls, including radon controls, that when added to Version 3 requirements provide a complete energy and indoor air quality home package. • Verification can be completed within the ENERGY STAR inspection process. 35

  36. How are the ENERGY STAR & Indoor airPLUS programs related? • Both are voluntary labeling programs run by EPA. • For more information, visit www.epa.gov/indoorairplus/ HVAC HVAC Radon Filtration Filtration VOC’s Moisture Moisture Pests Complete IAQ Protection IAQ Improvement 36

  37. ENERGY STAR HVAC approach • Build the home tight to improve efficiency & comfort. • Remove contaminants using occupant-controlled exhaust fan in kitchens & bathrooms and a filter in HVAC system. • Bring in outdoor air in a controlled way to dilute contaminants. • Include key durability details relating to water management. 37

  38. Value of a Complete Water Management System 38

  39. Why a Complete Water Management System? 3 • A water management system that keeps the roof, walls, foundation, site, and building materials from getting wet improves durability and indoor air quality. Water Management System 39

  40. Water Management System Checklist • One page verified by the builder during construction. • Benefits: • Increased durability. • Improved indoor air quality. 3 Water Management System Checklist 40

  41. Key Points about the Water Management System Checklist • Helps prevent durability problems from moisture. • Based on code requirements, plus best practices. • Especially important in high performance homes, regardless of whether the home is ENERGY STAR certified. 41

  42. The value of checklists • You can only expect what you inspect: • Checklists promote consistency. • Ensure full value from investments. 42

  43. The value of checklists Example: • A simple medical inspection checklist was developed to reduce infections from intravenous lines. • The checklist included five steps; straightforward advice, no new science, nothing controversial. • The checklist was used by intensive care units in MI over 18 months. • It nearly eliminated intravenous line infections. • It saved ~1,500 lives. 43

  44. Build Better Homes Sell More Effectively • Your Sales Sidekick 44

  45. Selling more effectively • What consumer wouldn’t love to learn about checklists? FOR NOT YAWNING 45

  46. Selling more effectively • Equal or better performance. • Cost-effective. • Meaningful improvement in efficiency. 46

  47. Market recognized value Annual Market Share of ENERGY STAR Certified Homes ~20% Market Share 47

  48. Market recognized value • 100% Corporate Commitments: • Beazer Homes • KB Home • Meritage Homes • NVR, Inc. • Plus, over 4,000 builder partners. 48

  49. Marketing resources - brand • Logos • Press releases • Leadership in Housing • Partner of the Year 49

  50. Marketing resources - website • Consumer website • Partner Locator • Web Linking • Consumer Video 50
