E2 has published new, interesting data on clean energy jobs by congressional districts. Clean energy employment[1] (jobs in renewable energy and energy efficiency) accounts for 3 million U.S. jobs, and the sector will likely grow following the passage of the massive infrastructure bill. E2’s searchable database allows users a closer look at where those jobs are.

Most home builders have a point-person responsible for ensuring that tradespeople are completing their work as specified. For some, that means there’s someone physically walking through homes after the insulation has been installed to ensure that the job is done properly. But do they know where to look? Our 25 checkpoints guide can help.

Each year since 2013, the U.S. Department of Energy (DOE) Housing Innovation Awards recognize forward-thinking builders who construct homes that are Zero Energy Ready (with net zero achievable with the addition of solar panels). Among the winners of the 2021 Housing Innovation Awards is Milwaukee-area builder Tim O’Brien Homes, which took a top prize for a 3,000 square foot high-performance custom home insulated with blown-in fiberglass insulation.

While some states have aggressive stretch energy code requirements, other states lag in their efforts. A new report from WalletHub, a personal finance company, analyzes data from various government agencies in 48 states and ranks each in their building, auto, and transportation efficiency. The report finds that Utah is the most energy-efficient state while South Carolina is the least. So how does your state rank?

Next Wednesday, October 6, marks the sixth celebration of Energy Efficiency (EE) Day 2021 (EEDay2021). EE Day is a collaborative effort including dozens of energy efficiency advocacy groups in the U.S., including the American Council for an Energy-Efficient Economy (ACEEE), Alliance to Save Energy, National Resources Defense Council, and regional energy efficiency organizations. The goal is to encourage consumers and organizations to save money, cut pollution, and create jobs by focusing on energy efficiency.

In home construction, getting great air sealing and insulation are the Holy Grail in delivering a high-performance home with an effective thermal envelope. The prevailing belief among many in the building industry is that only spray foam insulation can deliver the thermal performance and airtightness that is required but that simply isn’t true. Moreover, installed costs are a top consideration for most builders, thus finding products that can help builders meet thermal performance and airtightness targets for less is important. Insulation Institute looks this week at new case studies for residential construction that show even the most aggressive airtightness targets can be met cost-effectively without using spray foam.

For more than 25 years, the ENERGY STAR® Homes program has positioned itself as the market leader in cost-effective, energy-efficient new home construction. The Environmental Protection Agency (EPA) advertises that homes built to ENERGY STAR specifications are 10 to 20 percent more efficient than homes built to code1. But behind the advertising claim, what does an ENERGY STAR really demand from homes bearing its label? The ENERGY STAR Homes program reference designs for Versions 3 and 3.1 include 2009 and 2012 International Energy Conservation Code (IECC) envelope requirements, respectively. Oddly, the program’s inspection checklists only require the thermal envelope to meet 2009 IECC prescriptive requirements. ENERGY STAR also allows homes to go below 2009 IECC insulation2 levels if improved air sealing is achieved.

Man-made vitreous fibers (MMVFs) or synthetic vitreous fibers (SVFs), specifically glass, rock/stone or slag wools, have multiple end-use applications but are most commonly used as insulation. MMVFs have been studied by health and safety experts for decades. Most notably, the potential carcinogenicity (ability or tendency to produce cancer) of these fibers has been evaluated by toxicology studies in the form of large epidemiological cohort studies of MMVF manufacturing workers, in inhalation studies in experimental animals (in vivo), and in laboratory fiber solubility studies (in vitro).
