This technical bulletin highlights the differences and similarities between the three different ENERGY STAR Multifamily New Construction paths (ERI, ASHRAE and Prescriptive) and clarifies the Rater's responsibilities for each Path.
Americans are rapidly adopting plug-in electric vehicles (EVs). In fact, the Edison Electric Institute and the Institute for Electric Innovation estimate that 18.7 million EVs will be on U.S. roads by 2030. Because 80 percent of EV charging happens at home, consumer demand for homes ready for or equipped with EV charging is also growing. In addition, an increasing number of localities, such as Atlanta, Denver, and much of California, have begun to require that EV charging infrastructure be included in all newly-built single-family homes. Builders in other areas are starting to pre-wire or install charging units as a value added feature of their new homes as well.
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 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.
The transition to EPA's ENERGY STAR Multifamily New Construction (MFNC) program is fast approaching. Is your project team ready? Key participants for the Multifamily New Construction program include builders / developers, raters, functional testing agents, and ASHRAE path energy modelers. This technical bulletin highlights the key steps to complete before starting an MFNC project.
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.
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.
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.
