Track A - HVAC Grading by Rater is a collection of requirements built upon ANSI / RESNET / ACCA / ICC Standard 310 that can be used to satisfy many of the HVAC design and functional testing components of the ENERGY STAR Multifamily New Construction (MFNC) program. This technical bulletin highlights its key benefits, outlines how to use it, and compares it to the original set of requirements, now named Track B - HVAC Testing by Functional Testing Agent.
Track A - HVAC Grading is a collection of requirements built upon ANSI / RESNET / ACCA / ICC Standard 310 that can be used to satisfy many of the HVAC design and commissioning components of the ENERGY STAR Single-Family New Homes program. This technical bulletin highlights its key benefits, outlines how to use it, and compares it to the original set of requirements, now named Track B - HVAC Credential.
ENERGY STAR certified LED lighting products use 90% less energy and can last 25 times longer than traditional incandescent lighting. LEDs (short for “light-emitting diode”) also outperform CFLs (compact fluorescent or “spiral” light bulbs) in terms of energy efficiency, versatility, and durability, not to mention their appeal to energy-conscious consumers who have concerns about mercury gas in CFLs.
Demand water heaters - also known as tankless, instantaneous, or instant-on water heaters - are growing in popularity. These water heaters offer numerous advantages over traditional storage water heaters and are available for all major fuel types: electric, natural gas, and propane. Not only can demand water heaters improve convenience and comfort for the homeowner, they can make it easier to achieve the HERS Index Target for ENERGY STAR certification.
The average American household spends nearly half of their annual energy bill on heating and cooling. ENERGY STAR certified smart thermostats automatically adjust a home' temperature settings for optimal performance. This Technical Bulletin will offer tips and considerations for incorporating smart thermostats into ENERGY STAR Certified Homes and promoting their benefits to home buyers and renters.
The ENERGY STAR Certified Homes program regularly receives partner questions and comments and often makes improvements in response to this feedback. The Current Policy Record catalogs these issues and their resolution. You can review this document to stay up to date between revisions. This Technical Bulletin highlights key changes since the release of Revision 08.
Earlier this year, RESNET added an Index Adjustment Factor to the ANSI/RESNET/ICC 301-2014 Standard. While the Index Adjustment Factor (IAF) sounds a lot like ENERGY STAR’s Size Adjustment Factor (SAF), it actually serves a different purpose.
The two most commonly used residential HVAC design programs, Wrightsoft Right-Suite Universal and Elite RHVAC, can now automatically generate the ENERGY STAR HVAC Design Report. Before, HVAC designers laboriously copied design information onto the HVAC Design Report manually. With this major step forward, the HVAC Design Report is completed fast and accurately, standardizing the exchange of information between the HVAC and HERS rating industry.
ENERGY STAR had long offered two ways to certify modular homes: a plant-certification path and a Rater-verification path. With the introduction of Revision 09, the infrequently used plant-certification was eliminated to reduce potential marketplace confusion. Going forward, all modular homes permitted after January 1, 2019 should be verified using the same Rater-based process and program requirements as site-built homes.
