California’s largest net-zero-energy housing development is coming next year to the Central Valley.

The Superior Walls Xi Plus wall systems selected by the Hermitage Club construction team include one-inch foam insulated concrete studs and one-inch foam insulation on the bond beams to help ensure energy efficiency in the townhomes.

Two ASHRAE certification programs, the Building Commissioning Professional (BCxP) and Building Energy Assessment Professional (BEAP), have been recognized by the U.S. Department of Energy (DOE) as meeting the Better Buildings Workforce Guidelines (BBWG).

With 2016 having been the hottest year on record, sustainable technologies like cool roofs are becoming more mainstream among facility managers and architects.

It used to be that high-performance building was a niche market. Achieving energy efficiencies seemed a hurdle too high to get over and too costly to afford. Not anymore.

One solution could come in the form of eco-building materials that utilize natural substances known to have a positive effect on indoor air quality, Greenovate! Europe said.

Maine’s glut of softwood fiber created by closed paper mills makes the state an ideal location for a factory that can produce insulation board from wood.

Doug McMullen, technical sales of DatapointLabs, said the company runs a test laboratory where it characterizes materials, which he said lets injection molders get better simulation.

Both U-factor and R-value are measures of a material’s insulating performance. The former is a measurement of heat transfer; the latter measures heat resistance.

The Passive approach boils down to five building science principles that provide homeowners with predictable performance, unmatched comfort, superb air quality, and resiliency in the face of power outages due to winter storms or summer blackouts.
