The U.S. housing market saw a record low supply of homes for sale at 1.16 million in April, down 25 percent from the prior year. With demand driven by the lowest fixed mortgage rates in 50 years, a current housing shortage at 4 million homes nationwide,[1] and higher costs for building materials, land, and labor, any home building option that promises to speed construction while reducing costs is attractive. Enter 3D printed homes – an efficient, cost-effective, and resilient option for new home construction.

The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy recently issued a preliminary analysis of the 2021 International Energy Conservation Code (IECC), noting that the code will improve energy efficiency in residential buildings. DOE’s technical analysis of the updated code (relative to the 2018 IECC edition) pegs national savings of approximately:

If you’ve been following our blog for some time now, you know that we write regularly about basic building science. In fact, we completed a primer, Building Science 101 with Building Scientist Allison Bailes a few years back. Dr. Bailes, a Georgia resident, recently wrote the state’s Department of Community Affairs to object to a proposal that would allow as little as R-20 spray polyurethane foam (SPF) insulation to be used on the underside of the roof deck in new homes built in the state when R-38 is required. You may ask why R-20 SPF at a blower door rating of 3ACH 50 was proffered as a substitute for R-38 and 5ACH 50. So did Bailes.

Trading Off Thermal Resistance is a Very, Very Bad Idea

A report released this week by E2 (Environmental Entrepreneurs) highlights the tremendous impact of the pandemic on clean jobs. According to Clean Jobs America 2021, for the first time since the organization began tracking clean jobs, employment fell across the sector in 2020. The pandemic, the resulting economic fallout, and the lingering impacts of policies of the previous administration all contributed to a decline of 11 percent in the total number of clean jobs, the report notes.

Fiberglass batts are commonly used to insulate flat ceilings and attic areas in both new and existing buildings. They offer performance, cost-effectiveness, and relative ease of installation, but that doesn’t mean they’re always installed properly. The performance of any insulation product is dependent not only on selecting the proper product but also on installing it correctly. So, how does one install batts in flat ceilings to maximize thermal performance?

NAIMA has released a new report that documents the acoustical performance of residential wall cavity insulation products. The report is based on research conducted by Intertek Labs that tested seven wall assemblies with variations in cavity insulation products, including fiberglass, mineral wool, open cell spray foam, closed cell spray foam, and flash and batt applications with spray foam and fiberglass insulation.

3 Pandemic Housing Trends to Watch

NAIMA/Insulation Institute frequently fields questions regarding various performance aspects of fiberglass and mineral wool insulation. One of the most common questions we receive is, “what is the typical lifespan of fiberglass and mineral wool insulation?” Other questions come up regarding settling and loose fill insulation. We know there are many misconceptions about fiberglass and mineral wool insulation products’ performance and longevity, so pointing out research that can help dispel myths is often necessary.
