Within the residential sphere specifically, some standout projects were delivered to market this past year. One such home, the Jacobson House in Northern California, garnered the spotlight with its unique story and innovative energy solutions.


Justin Koscher, president of PIMA takes a close look at the many benefits of energy codes beyond energy efficiency and the resulting cost savings.

Continuous insulation (ci) and cavity insulation products are both sold with R-value ratings, but the way these two products are used in wall construction means they do not have the same effectiveness.

If you’re interested in insulation, you may be surprised to learn that researchers have found that by stripping away all the filler material in wood, leaving just their fibres, the resulting “nanowood” material outperforms just about all existing insulation.

RESNET announced that 13 builders will be added to the group of over 170 RESNET EnergySmart Builders who have committed to having all their homes rated to RESNET’s stringent energy efficiency standards.

The newest versions of IECC and ASHRAE Standard 90.1 call for one to four inches of exterior continuous insulation depending on the building location by climate zone, even in warmer zones where foam board insulation had not previously been required.

Hillcrest Residences has become the largest confirmed Passive House Institute U.S. certified (PHIUS) development in North America by square footage and number of units, according to a release from the developer.
