Building Science

Congressional lawmakers passed a $1.3 trillion omnibus spending bill that was signed into on Friday, March 23. The omnibus will increase the Department of Energy's (DOE) budget to $34.5 billion (almost $4 billion more than FY 17). This includes additional funds to the following programs:

Aerosol-based duct sealing proves more effective and produces a faster return on investment compared to traditional sealing methods, according to a new study.

Most home buyers focus on price and payments, however, factoring in a home’s energy consumption costs could save tens of thousands of dollars over years of ownership.

Here’s a look at the three key mistakes builders make that foster mold and rot and how to avoid them.

Dense-blown cellulose is an important problem-solver for high-performance builders and remodelers. In a retrofit situation, when you blow the material into a leaky wall cavity, you can reduce infiltration losses at the same time you boost insulation values.

When Dow and DuPont merged to create DowDuPont, it brought together two science-based companies that were positioned at the leading edge of the agriculture, materials science and specialty products industries.

According to Pembina Institute, the average construction cost premium of Passive House projects is just 6 percent. Data from Pennsylvania Housing Finance Agency suggest that this premium could be as low as 2 percent for multifamily buildings.

Various types of insulation have been used in masonry cavity walls: rigid foam boards, spray polyurethane foam (SPF) and mineral wool. Among these, two rigid foams predominate: extruded polystyrene (XPS) and polyisocyanurate (polyiso).

This project has forced our team to focus on the energy-efficient side of home building. We realized early on we could not expect to achieve Net-Zero without also paying close attention to build quality, engineering and architecture.

Making sure that your home is properly insulated is an important step to ensure that your home remains comfortable year round and avoids wasting energy. Understanding the most common signs that your property is under-insulated can determine the best steps to improve the overall energy efficiency.
