Section 1: Partnering with ENERGY STAR 4

Working with a Rater A critical element of partnering with ENERGY STAR as a builder is working with a Home Energy Rater*. Your Rater can work with you to: Evaluate home plans to pinpoint specific improvements needed to qualify your homes for the ENERGY STAR label Provide field verification including independent inspections and testing required for your homes to earn the ENERGY STAR Assist with program participation including helping you fully understand the ENERGY STAR for New Homes guidelines Provide training for your construction staff and subcontractors Provide marketing assistance including integrating ENERGY STAR tools and messages NOTE: *The term “rater" refers to the person completing the third-party inspections required for qualification. This party may be a certified HERS Rater, BOP Inspector, or an equivalent designation as determined by a Verification Oversight Organization such as RESNET. 5 Section 1: Partnering with ENERGY STAR

Reporting Qualified Homes to EPA Quarterly Updates Raters, through their Accredited Providers, submit quarterly updates to EPA for the number and location of ENERGY STAR qualified homes constructed by each builder. Only Accredited Providers can report ENERGY STAR qualified homes directly to EPA through an on-line reporting system. Inactive Partnership Based on Reporting At least one ENERGY STAR qualified home must be reported to EPA within 12 months to maintain an active partnership. If not, your partnership will be made inactive and you will be notified via (you will also receive a warning 3 months before). –If you receive an ‘inactive ’ from EPA and believe it to be in error, you should contact your rater to determine why your homes were not reported. –When a new ENERGY STAR qualified home is reported to EPA, your partnership will be automatically re-activated. 6 Section 1: Partnering with ENERGY STAR

7 ENERGY STAR Labels Labeling Requirement ENERGY STAR builder partners must ensure that an ENERGY STAR label is completed and affixed to the circuit breaker box (or other suitable location) on all qualified homes. This is the ‘proof’ that the home has earned the ENERGY STAR. Source of Labels EPA provides ENERGY STAR labels to Accredited Providers for free. The Provider will distribute the completed label to your Rater or directly to you to post in the home.

Section 3: ENERGY STAR for Homes Version 3 19

ENERGY STAR Version 3: Background Time for Change: In 2010, EPA released new guidelines for homes to earn the ENERGY STAR label (referred to as ‘Version 3’). These were developed in response to critical external forces: –As new national and regional energy codes were rapidly increasing, new guidelines were needed to ensure that ENERGY STAR qualified homes continued to represent a meaningful improvement in energy efficiency over homes built to code and standard building practices. –Augmenting the guidelines with cost-effective energy efficiency technologies and building science practices will help improve home efficiency, durability, and indoor air quality of ENERGY STAR qualified homes. 20 Section 3: ENERGY STAR for Homes Version 3

ENERGY STAR Version 3: Resources Technical Resources Field guides and technical presentations have been developed to help builders successfully implement the requirements of ENERGY STAR for Homes Version 3. Where to Find Resources All Version 3 documents are available at under “Guidelines and Technical Resources.” 21 Section 3: ENERGY STAR for Homes Version 3

22 ENERGY STAR Version 3: Major Changes Variable vs. Fixed HERS Score Instead of a fixed HERS Score, a variable HERS Index Target Score is calculated for each home by applying a set of specifications called the ENERGY STAR Reference Design. Renewables Unlike Version 2 of the guidelines, you can take credit for renewable energy systems, but only to help large homes meet the additional efficiency required by the Size Adjustment Factor. Section 3: ENERGY STAR for Homes Version 3

23 ENERGY STAR Version 3: Major Changes Size Adjustment Factor –Homes larger than the average size for a specified number of bedrooms (called the ‘Benchmark Home Size’) must apply a Size Adjustment Factor that will reduce the ENERGY STAR HERS Index Target. This will increase the energy efficiency requirements for larger homes. –Bedrooms and floor area in basements that are mostly below grade are excluded when determining a home’s Benchmark Home Size, comparing the home against the Benchmark Home Size, and calculating the Size Adjustment Factor. Section 3: ENERGY STAR for Homes Version 3

24 ENERGY STAR Version 3: Major Changes Section 3: ENERGY STAR for Homes Version 3 Variable vs. Fixed HERS Score Instead of a fixed HERS Score, a variable HERS Index Target Score is calculated for each home by applying a set of specifications called the ENERGY STAR Reference Design. Checklists To earn the ENERGY STAR label, all homes must now be inspected for compliance with a new set of checklists.  Two checklists are to be completed by the Home Energy Rater,  One checklist by your HVAC contractor, and  One checklist by you, the builder.

25 ENERGY STAR Version 3: Overview Under the new guidelines, homes earn the ENERGY STAR meeting a combination of core energy efficiency measures and mandatory inspection checklists. Inspection Checklists The mandatory inspection checklists ensure that additional building science features are included in qualified homes. Section 3: ENERGY STAR for Homes Version 3

26 ENERGY STAR Version 3: Overview The core energy efficiency features can be met using either: Prescriptive Path –The home is designed and built to a pre-defined set of specifications (called the “ENERGY STAR Reference Design”) for the climate where the home will be built. No trade-offs are allowed. –The ENERGY STAR Reference Design provides efficiency requirements for the building envelope, HVAC and water heating equipment, lighting, and appliances. –Only homes the same or smaller than their corresponding Benchmark Home may use this path. Performance Path –A rater models the home to establish an ENERGY STAR HERS Index Target for the home. For homes larger than their Benchmark Home, this ENERGY STAR HERS Index Target will take into account the Size Adjustment Factor. –The builder then has the flexibility to select a custom set of energy-efficiency measures to earn the ENERGY STAR label for the home, so long as the home’s HERS Index Target threshold is met or exceeded. Section 3: ENERGY STAR for Homes Version 3

Qualifying Homes Under Version 3 1.Check eligibility. 2.Check Benchmark Home Size. 3.Select Version 3 energy efficiency measures. 1.Build the home using the ENERGY STAR Reference Design. 2.Complete the inspection checklists. Prescriptive Path 1.Model the home and create the ENERGY STAR Reference Home. 2.If the home is larger than the Benchmark Home Size, apply the Size Adjustment Factor to find the ENERGY STAR HERS Index Target. 3.Select upgrades that meet the mandatory requirements and achieve a HERS Index ≤ ENERGY STAR HERS Index Target. 4.Complete the inspection checklists. These steps are new and will be performed by your rater. These steps are the same as under Version 2. Performance Path

28 Homes can be qualified through the Prescriptive Path when: The home is the same size or smaller than the Benchmark Home Size; The home has been designed and constructed to the ENERGY STAR Reference Design with no trade-offs; and The home passes all required tests and meets the requirements of the Inspection Checklists. Section 3: ENERGY STAR for Homes Version 3 Using the Prescriptive Path

Using the Performance Path The ENERGY STAR Reference Home is used to set the performance threshold that each home qualified under the Performance Path must meet. This threshold is called the ENERGY STAR HERS Index Target. Your rater will configure a customized ENERGY STAR Reference Home for the home you want to build. Section 3: ENERGY STAR for Homes Version 3 29

Using the Performance Path If the home you want to build is larger than the Benchmark Home Size, they will apply a Size Adjustment Factor. The Benchmark Home Size is defined by the table below: Remember that bedrooms and square footage in basements that are mostly below-grade are not counted when finding the Benchmark Home Size. Your rater will use the ENERGY STAR Reference Home and the Size Adjustment Factor to create an ENERGY STAR HERS Index Target. This is the performance threshold that the home you want to build must meet to earn the ENERGY STAR. Section 3: ENERGY STAR for Homes Version 3 Bedrooms CFA1,0001,6002,2002,8003,4004,0004,6005,200 30

Select upgrades The builder has the flexibility to select a custom set of energy efficiency specifications, so long as the resulting HERS Index meets or exceeds the ENERGY STAR HERS Index Target and other requirements (e.g., minimum efficiency for windows, insulation) are met. Verification The home must be designed and constructed to the customized specifications and pass all required inspections and testing. Performance Path Compliance Section 3: ENERGY STAR for Homes Version 3 31

32 ENERGY STAR Version 3: HERS Rater Checklists Checklists to be completed by your Home Energy Rater: Thermal Enclosure System Rater Checklist –This checklist is designed to ensure that the exterior building shell/envelope of ENERGY STAR qualified homes are optimized for efficiency and durability. –This checklist replaces the Thermal Bypass Checklist that was part of the last ENERGY STAR for Homes guidelines. HVAC Quality Installation Rater Checklist –This checklist is used to verify that the home’s ductwork and ventilation system have been installed properly, and provides additional validation of HVAC contractors’ work. Section 3: ENERGY STAR for Homes Version 3

ENERGY STAR Version 3: HVAC Contractor Checklist Checklist completed by your HVAC Contractor: HVAC Quality Installation Contractor Checklist This checklist ensures that the heating and cooling systems in ENERGY STAR qualified homes are designed and installed according to industry-accepted quality installation practices. Only HVAC contractors who have demonstrated the requisite skills and capabilities to perform HVAC Quality Installations will be permitted to complete this checklist. To ensure that your HVAC contractor is credentialed, you can refer to a list provided through the ENERGY STAR Web site. 33 Section 3: ENERGY STAR for Homes Version 3

ENERGY STAR Version 3: Builder Checklist Water Management System Builder Checklist This checklist requires an inspection of key areas of ENERGY STAR qualified homes to help assure bulk moisture control, including water- managed foundation, walls, roofs, and building materials. This checklist must be completed by the site supervisor or other qualified individual on the builder’s staff. Your Rater may also verify items on the checklist; however, you as the builder are responsible for accuracy of all checklist requirements. Completed and signed checklist should be provided to your Home Energy Rater to keep with the home’s ENERGY STAR file. As an alternative to completing this checklist, the house can be qualified under EPA’s Indoor airPLUS programIndoor airPLUS program 34 Section 3: ENERGY STAR for Homes Version 3

Special Considerations When local codes or manufacturer’s guidance meet or exceed ENERGY STAR requirements, the more rigorous requirements must be met. When codes or manufacturer’s guidance conflicts with ENERGY STAR requirements, work with your rater to determine if there’s an alternate way to achieve the intent of the ENERGY STAR requirement. If there is no equivalent option, then the ENERGY STAR requirement can be waived and the home can still be qualified. 35 Section 3: ENERGY STAR for Homes Version 3
