PRLog -- Bobby Corgan, custom home builder, with Corgan Associates has always wanted to stay abreast of the new construction innovations for his clients. On June 4th 2014 he attended a Zero Energy Conference and completed the course requirements . The conference was held by , Building Savvy and titledU.S. Department Of Energy Zero Energy Ready Home Training presented by Armando Cobo MCGP, CGP, CGA, CAPS Green Building Designer, Consultant & Instructor DOE's Zero Energy Ready Home Program represents a whole new level of home performance, with rigorous requirements that ensure outstanding levels of energy savings, comfort, health, and durability. Topics covered were: The Thermal Enclosure and All Involved Systems Energy Star V3 Baseline ERV Balanced Ventilation Systems – Temperature, Humidity, Ventilation IAQ T-Stat Insulation- Foam, vs Fiberglass Alternative Energy Sources- Wind, Geothermal, Solar DOE Energy Ready Requirements. Bobby Corgan learned that to qualify as a DOE Zero Energy Ready Home, a home shall meet the minimum requirements specified below, be verified and field-tested in accordance with HERS Standards by an approved verifier, and meet all applicable codes3,4 that have their own heating, cooling, and hot water systems1. Builders may meet the requirements of either the Performance Path or the Prescriptive path to qualify a home.2 Buildings eligible for qualification are: single family detached and attached dwelling units; dwelling units in multifamily buildings with 3 stories or fewer above-grade3,4 ; dwelling units in multifamily buildings with 4 or 5 stories above-grade5 separate from other units and where dwelling units occupy 80% or more of the occupiable square footage of the building. Bobby Corgan explains that when evaluating mixed–use buildings for eligibility, exclude commercial / retail space when assessing whether the 80% threshold has been met. Homes may qualify for DOE Zero Energy Ready Home using either the Prescriptive Path or Performance Path in all locations except CA and WA, for which regional program requirements have been developed. Note that compliance with these guidelines is not intended to imply compliance with all local code requirements that may be applicable to the home to be built. DOE Zero Energy Ready Home Prescriptive Path The prescriptive path provides a single set of measures that can be used to construct a DOE Zero Energy Ready Home labeled home. Modeling is not required, but no tradeoffs are allowed. Follow these steps to use the prescriptive path: 1. Assess eligibility by using the number of bedrooms in the home to be built to determine the conditioned floor area (CFA) of the Benchmark Home, Exhibit 3. If the CFA of the home to be built exceeds this value, the performance path shall be used. 2. If the prescriptive path is eligible for use based on the prior step, build the home using the mandatory requirements for all labeled homes, Exhibit 1, and all requirements of the DOE Zero Energy Ready Home Target Home, Exhibit 2. The rigor of the specifications in Exhibit 2 shall be met or exceeded. 3. Verify that all requirements have been met using an approved verifier.6 All homes certified through the Prescriptive Path shall be submitted to DOE (email: doechallengehome@

. DOE Zero Energy Ready Home Performance Path While all mandatory requirements for labeled homes in Exhibit 1 shall be met, the performance path provides flexibility to select a custom combination of measures that meet the performance level of the DOE Zero Energy Ready Home HERS Target Home (Exhibit 2).Bobby Corgan says that modeling is required, but measures can be optimized for each particular home or builder. Follow the steps below to use the performance path with RESNET-accredited Home Energy Rating Software programs: 1. The HERS Index of the DOE Zero Energy Ready Home Target Home is determined. According to Bobby Corgan, the DOE Zero Energy Ready Home Target Home is identical to the home that will be built, except that it is configured with the energy efficiency features of the DOE Zero Energy Ready Home Target Home as defined in Exhibits 1 and 2. Note, any state energy code requirements that exceed those specified on Exhibit 2 take precedence for purposes of determining the DOE Zero Energy Ready Home Target Home7. The HERS Index of the Target Home is automatically calculated in accordance with the RESNET Mortgage Industry National Home Energy Rating Standards. 2. A size modification factor is next calculated using the following equation: Size Modification Factor = [CFA Benchmark Home / CFA Home To Be Built] 0.25, but not to exceed 1.0 Where: CFA Benchmark Home = Conditioned Floor Area of the Benchmark Home, using Exhibit 3 CFA Home to be Built = Conditioned Floor Area of the Home to be Built Since the Size Modification Factor cannot exceed 1.0, it only modifies the HERS Index score for homes larger than the CFA of the Benchmark Home. 3. The HERS Index of the DOE Zero Energy Ready Home Target Home is calculated next8: 4. Complete HERS software calculations for preferred set of energy measures and verify resulting HERS Index Score at or below DOE Zero Energy Ready Home Target Home HERS Index Score modified, as required, for house size. 5. Construct the home using measures that result in a HERS Index at or below the DOE Zero Energy Ready Home HERS Target, calculated above, and the mandatory requirements for all labeled homes, Exhibit 1. 6. Verify that all requirements have been met using an approved verifier. Bobby Corgan mentions that all homes certified through the Performance Path shall be submitted to DOE by submitting the compliance verification report to doechallengehome@
