ENERGY STAR Certified Homes 101 Jennifer James, ICF International on behalf of EPA March 12 th, 2013
What you will learn 1.Basics of ENERGY STAR 2.The new value of an ENERGY STAR certified home. 3.The sales support that ENERGY STAR brings to building partners. 2
The Value of ENERGY STAR 3
ENERGY STAR Certified Homes Build Better Homes Sell More Effectively 4
How to build better homes Build Better Homes 5
Core efficiency measures Guarantees that efficiency measures are included in every certified home. Prescriptive Path Performance Path 6
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. 7
Mix and match 8
The risk of incomplete systems 9
Value of a Complete Thermal Enclosure System 10
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. 11
Thermal Enclosure System Checklist 1 Less than two pages, verified by the Rater. Benefits: – Reduction in hot/cold spots. – Less heating and cooling energy. – Potential for HVAC downsizing. 12
Section 3: Fully-aligned air barriers 14 Section 3: Often overlooked areas Air barrier....aligned with insulation Section 3: Complete air barrier aligned with insulation
Thermal enclosure system 15 Space Constrained Area In an ideal energy world…
Section 1: High-performance fenestration 16 Defines U-value and Solar Heat Gain Coefficient requirements
Section 4: Reduced thermal bridging 17 Addresses thermal bridging – places in the home where insulation is missing due to framing or space constraints. Studs conduct heat more easily than insulation
Sections of the Thermal Enclosure System Rater Checklist 18 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.
Value of a Complete HVAC System 19
Why a Complete HVAC system? 2 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. 20
HVAC system Checklists 2 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. 21
Heating & Cooling Systems: Putting the “H” and “AC” in “HVAC” 22
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
Basic heating & cooling systems design 105F 73F 72F 24 Adding & removing Btu’s impacts the temp. inside the home.
Three major steps to design an HVAC system 25 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.
Step 1: Calculate heating & cooling loads 26 Cooling load is the maximum Btu’s added in one hour.
Step 1: Calculate heating & cooling loads 35°F 72°F 27 Heating load is the maximum Btu’s lost in one hour.
Step 2: Select equipment that meets loads 72°F 73°F 28 Select equipment that removes Btu’s to meet cooling load.
Step 2: Select equipment that meets loads Select equipment which adds Btu’s to meet heating load. 72°F 71°F 29
Step 3: Design the duct system Design ducts to properly distribute air through house. This offsets the loads. 30
Value of heating & cooling systems Two components of a complete system: 31 Proper design Proper installation
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
Ventilation Systems: Putting the “V” in “HVAC” 33
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 high-quality indoor air! This home has low-quality indoor air! 34
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
Radon VOC’s Pests How are the ENERGY STAR & Indoor airPLUS programs related? Both are voluntary labeling programs run by EPA. For more information, visit HVAC Filtration Moisture HVAC Filtration Moisture IAQ Improvement Complete IAQ Protection 36
1.Build the home tight to improve efficiency & comfort. 2.Remove contaminants using occupant-controlled exhaust fan in kitchens & bathrooms and a filter in HVAC system. 3.Bring in outdoor air in a controlled way to dilute contaminants. 4.Include key durability details relating to water management. ENERGY STAR HVAC approach 37
Value of a Complete Water Management System 38
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. 39
Water Management System Checklist 3 One page verified by the builder during construction. Benefits: – Increased durability. – Improved indoor air quality. 40
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. Key Points about the Water Management System Checklist 41
The value of checklists You can only expect what you inspect: – Checklists promote consistency. – Ensure full value from investments. 42
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
