According to U.S. Department of Energy 20 percent home’s energy is wasted because the home is under insulated and improperly air sealed.[1] For builders, this can wreak havoc on productivity, resulting in call backs, jeopardizing code compliance, reducing HERS scores, and resulting in homes that are less energy efficient and comfortable for consumers.

Home buyers and owners aren’t just concerned about energy efficiency, they’re increasingly interested in the water efficiency of homes as well, due in part to double-digit increases in water costs over the past few years in many areas of the country. Growing interest in water efficiency has prompted Residential Energy Services Network (RESNET) to partner with the International Code Council to develop a national consensus standard for home water efficiency dubbed HERSH20. The standard will define how to calculate a rating index for home water efficiency.

Custom home buyers have very discriminating requirements when it comes to designing and constructing their homes. Increasingly, those needs incorporate the desire to be sustainable and energy efficient. When sustainable architectural firm SUSTAINABLE.TO Architecture + Building and Greenbillt Homes, a leading Canadian custom home builder teamed up design and construct a home in North York, Ontario, they were directed to deliver a tall order to their clients: designing a home that would “sip energy, endure for generations and remain comfortable at all times.” The result was a striking residence that incorporates mineral wool insulation and delivers some impressive energy performance results.

Since 2013 the U.S. Department of Energy’s (DOE) Housing Innovation Awards has recognized the top builders of zero energy ready homes. Housing Innovation award winners represent the top one percent of builders across the country who meet the most rigorous specifications for High-performance Homes. Among this year’s 24 winners is production builder Charles Thomas Homes.
Founded in 2009, Charles Thomas Homes constructs High-performance Homes that typically command a higher price than competing builders, but also deliver on energy efficiency and comfort, which is important in frosty climate zone 5. Part of the company’s winning approach to constructing energy-efficient homes includes blown fiberglass insulation in the attic and walls, demonstrating that high-performance doesn’t have to mean high price.

There’s all kinds of potential for smarthome devices, from better security to an easier way to turn off the lights. But one of the greatest benefits—at least, environmentally-speaking—is the ability to provide more insight into a home’s energy consumption. Stand-alone smartphone apps can offer suggestions for how to incorporate greener habits into a homeowner’s daily routine. And then there are the device-centric apps, which integrate with existing smart products in the home—such as the utility meter or thermostat—to give homeowners a better readout of their energy use and saving.

Ask any builder around the country about top challenges and you are pretty likely to hear three things:
A report released recently by E4 The Future, which promotes residential clean energy and sustainability, examines the body of research supporting the considerable benefits of home performance/energy efficiency measures. The report concludes that not only do energy efficiency measures, such as increased insulation and air sealing, improved heating, and ventilation increase the comfort of the home, but also provide considerable occupant health benefits.

A collection of national, state and regional organizations are driving building energy efficiency through advocacy, research, policy analysis and action
There’s no shortage of information on the economic, energy security and environmental benefits of energy efficiency and new statistics emerge every week. But, while information on the myriad advantages of energy efficiency is abundant and accessible, lesser known are the organizations that are quietly taking a leading role in advancing building and home energy efficiency. This week, we highlight just four of the many organizations driving building energy efficiency at the national, state and regional level:

In a blog post last month, we posed the question: do consumers want energy efficiency upgrade options? Since then, we’ve received feedback from high performance building advocates, builders and architects – one in particular who offered guidance on selling energy efficient home options to today’s homebuyers.
Antonio de la Carrera of ADLCL Architecture is a Dallas-area architect with experience in sustainable, energy efficient and Net Zero custom homes in cities including Dallas, Boston, Chicago and Mexico City. His experience has led him to identify three crucial tips that builders of all types and sizes should use to better sell energy efficiency.

Back in December we wrote about a change in the 2018 IECC that laid out a new, prescriptive path for the use of buried ducts in standard vented attics. This practice offers the potential to save significant energy over typical vented attic designs, and can even rival the savings of an unvented attic done with ccSPF under the roof deck, at much lower cost. However, like much of the building code, actually understanding and applying the language is not always easy. To help, we contracted with Home Innovation Research Labs (HIRL) to create a “TechSpec” that lays out how you undertake the practice in a simple, straightforward manner. In addition, HIRL also provides both construction and energy costs of different attic design approaches, including variants of buried ducts. The document speaks for itself, but since our first communication on this new practice we have heard feedback on some areas of confusion that need to get cleared up. Here are the answers to 5 common questions about buried ducts.
