Lessons From Brad Pitt’s Effort to Make It Right

What was a lofty philanthropic effort by actor Brad Pitt has morphed into a disastrous example of how poor construction of affordable, energy-efficient housing can negatively impact homeowners and put the builder and building designer in a precarious position.

NOLA.COM reported this week that in 2007, two years after Hurricane Katrina, Make it Right Foundation, organized by Pitt, set a goal of constructing 150 energy efficient, sustainable and affordable homes for residents of Louisiana’s devastated Lower Ninth Ward. The foundation constructed 109 homes, but just 11 years after the start of construction, reports say that some homes have issues including rotting wood, mold growth, dangerous air quality, and rusty sockets. The majority of the homes are currently unoccupied and some have been demolished.

Master the Training, Witness the Test

In the quest to meet new energy code requirements of the 2012/15 International Energy Conservation Code (IECC), some builders are finding that passing that all-important blower door test is their biggest challenge. As we’ve reported earlier this year, only 40 to 50 percent of new construction homes that must now meet the 3 ACH50 blower door target will pass the first test, but builders can increase the initial pass rate, according to Cosco Jones, owner of Jones Sustainable Solutions Group. Jones is a HERS rater who’s worked with more than a dozen builders to improve the energy performance of their new construction homes. He offered his advice to builders on how to not only increase the pass rate for blower door testing but also reduce their costs in the process.

Home Design with Wi-Fi in Mind

There are more Wi-Fi devices in use than there are people on Earth and about 50 percent of Internet traffic flows through Wi-Fi networks.[1] Wireless devices are everywhere, so it’s easy to understand why Wi-Fi connectivity is critical for homebuyers.  Virtually everyone has had that experience of being in a home or building that has weak Wi-Fi connectivity, and that can be a major headache for buyers who rely on Wi-Fi connections.

For builders, designing a home with connectivity in mind is essential to ensuring homeowners don’t have to keep asking, “is the W-Fi off??”

Don’t Park the Prius on the Roof!

Don’t Park the Prius on the Roof

In this age of technology, one of the great ironies of modern home shopping is that buyers more often than not consider resale homes first over new construction. In fact, in some markets, up to 90 percent of homes sold are lower priced, less efficient resale homes. Homebuilders can reverse that trend by demonstrating how and why newer homes outperform resales.

3 Commonly Missed Air Leakage Pathways

In our effort to help builders and contractors reduce air leakage in new construction homes, much of the focus has been on the building envelope. However, there are other areas outside of the building envelope that can prove problematic for air leakage. Bob Nelson of Ener-G Home Performance Consultants shed some light on three commonly overlooked areas that can contribute considerably to air leakage and often, help contribute to the 50 percent initial failure rate on blower door testing of new homes.

Eye on Fiber Glass and Mineral Wool Health and Safety

The Role of Data in Assessing the Potential Hazards of Man-Made Vitreous Fibers

The North American Insulation Manufacturers Association (“NAIMA”) occasionally gets questions about the health and safety of fiber glass and mineral wool insulation products.  To answer those questions, NAIMA is launching a new blog series.  Our first post is on the use of data in assessing possible fiber hazards.

Future-Proof Home Construction

In his more than 30 years as a residential building contractor, Jim Iredale focused much of his career on constructing code-built custom homes. That changed in 2012 when he had the opportunity to work on a very high-end project that was designed to meet passive haus (house) standards, and a devotee was born.

Want More of a Good Thing? Switch Your Trusses

By: Matthew Brown, CGP, APA Engineered Wood Specialist

Insulation can increase a home’s energy efficiency, but only if it’s properly installed. Batt insulation installed as per manufacturer instructions should perform at its stated value, but R-value can decrease if it’s compressed in tight spaces.

In roofing assemblies, conventional trusses can restrict insulation space above the exterior wall top plate, resulting in compressed insulation. Raised-heel trusses can provide a significant boost to the insulating power of a home.

Right-Sizing AC in High-Performance Homes

Some people think that the idea of a high-performance building is a new concept, but it has been around for some time now. As defined in the Energy Policy Act 2005, a building that “integrates and optimizes all major high-performance building attributes, including energy efficiency, durability, life-cycle performance, and occupant productivity” is a high-performance one.

Today, many builders have already applied the principles of a high performance into their homes, and homeowners are now enjoying the benefits of living in a place that sets the bar much higher for energy efficiency, comfort, durability, indoor air quality, and the use of sustainable products.

Energy Data Gains Traction in Home Listings

What impact will energy data for 110 million homes have on the energy efficiency industry?

By: Ryan Meres, RESNET Programs Director

For more than a decade studies have consistently shown that home buyers want energy-efficient features, but few are aware of the impact those features have on energy cost. The average U.S. homeowner spends more on energy than property taxes and insurance, but energy is the only one of those three common expenses not considered in the mortgage process. The announcement and report released by the Rocky Mountain Institute (RMI) that real estate platforms have begun including energy information in their listings is a significant step toward reducing the barrier to the transparency of energy use in the home-buying process.
