Major Study Shows ASHRAE 62.2 Ventilation Works!

A significant research report published in April of this year by the National Center for Healthy Housing (NCHH) found that subsidized multifamily housing with ASHRAE 62.2-compliant ventilation had better indoor air quality than housing without 62.2-compliant ventilation. This important research states: “Levels of four of the five indoor contaminants improved substantially with [continuous] mechanical ventilation."

Core Sampling Cellulose Insulation Density

It is often useful to be able to determine the installed density of dense-pack cellulose in a wall. Because the installer must work without the benefit of viewing the coverage or density, core sampling was devised many years ago to measure these important metrics. If the density is too low, the R-value and air leakage degrade. If the density is too high, insulation and labor are wasted.

Better Sleep Leads to Sweeter Building Science Dreams

Sleep is vital to our health, including our immunity from disease, heart function, and even reproductive vitality. A bad night’s sleep might contribute to poor performance at work and a sour emotional state the next day. It is difficult to assign a cost to a bad night’s rest, but I think most of us agree that it’s a cost we would rather avoid.
