The RESNET 2020 conference held in Phoenix this week, included a live demonstration session on getting Grade I installation with batt insulation. For anyone tasked with reviewing batt insulation jobs, this hands-on, open forum training offered a chance to review what a Grade I job looks like — and what it doesn’t.

Energy efficiency is indisputably essential to addressing global climate change. At the forefront of organizations promoting strategies to tackle the climate crisis is the Natural Resources Defense Council (NRDC). Insulation Institute spoke with David Goldstein, Co-Director of Climate and Energy at NRDC, about how the building sector in America can more aggressively pursue a comprehensive energy efficiency initiative to address climate change. Goldstein is a heavy hitter in the energy efficiency arena, having worked since the 1970s on energy efficiency and energy policy (and also founded Residential Energy Services Network). Goldstein offers the following four-point blueprint for achieving an active decade of progress on climate goals.

Leadership in Energy and Environmental Design (LEED) is the most widely used green building rating system in the world, and the number of LEED-certified buildings in the United States continues to grow. The U.S. Green Building Council (USGBC) recently released the top 10 states for LEED Green building in 2019, a year in which the total number of certified projects reached 1,181.

Sealing common air leakage pathways is key to achieving a tight thermal envelope. Often, hidden holes in new construction homes can make achieving an airtight envelope very difficult. Knowing where these hidden holes tend to occur can help builders avoid a massive air leakage issue. Our 10 Hidden Air Leaks in New Construction Homes guide covers the most common areas where these holes occur and offers solutions to fix the holes during the construction process.

The number of HERS-related homes in the United States continues to expand, according to new data released by Residential Energy Services Network (RESNET). In 2019 a total of 241,909 homes in the United States were HERS-rated compared with 236,116 in 2018. That is an increase of 5,793 homes in one year. To date, 2.7 million homes have been HERS-rated.

Home Sellers Must Prove Energy Efficiency
As we reported in last week’s blog post, “Five Promising Developments for Decarbonization,” a growing number of state and local governments are targeting building emissions to reduce their carbon footprint. This push for decarbonization will only accelerate. In the move toward decarbonization, targeting buildings – both commercial and residential – is low-hanging fruit. It’s not just new construction, but existing construction as well, with home sellers in one jurisdiction now required to measure their home’s energy efficiency before putting it on the market.

As a new decade begins, there are promising developments on the horizon for building decarbonization and greenhouse gas (GHG) emission reductions in residential and commercial construction. While federal support for decarbonization to address climate impacts is at a standstill, non-governmental organizations, state and local governments, and industry are all focused on sustainability and building decarbonization actions that may ultimately lead to real progress. Here are five promising developments for decarbonization that have the potential to shape an active decade of progress.

Like last year, some of our best-performing blog posts focused on air sealing and proper installation and application of fiberglass and mineral wool insulation, which is no surprise, since we’re the Insulation Institute. However, other topics like energy efficiency design trends and the prioritization of energy efficiency over energy generation ranked highly as well.

Residential building energy code adoption and implementation have expanded steadily in the U.S. in recent years, with roughly 40 percent of states having a residential energy efficiency code that is equivalent to or higher than the 2015 IECC. With all the progress that’s occurred in recent years, is the building industry reaching peak efficiency? If not, what more can be done to spur states to adopt and enforce building energy efficiency codes, and how does the industry support home builders still struggling to understand new codes? Insulation Institute spoke with Matthew Cooper, Senior Vice President of PEG LLC, about the current state of code adoption, implementation, and enforcement and what measures could improve energy-efficient construction in the U.S. today and in the future.

Getting accurate estimates for insulation installation jobs in new construction homes sounds like a relatively simple undertaking, but for some contractors, getting precise material quantities for jobs can be a challenge. Do you use software to estimate materials, or do you have an estimator review the construction plans? Is it necessary to “walk the house” to get the materials estimates? What’s the best approach? Insulation Institute talked with three building industry professionals about providing accurate estimates for batt and blown in insulation jobs and why it matters to get it right the first time.
