In 2015, the Seattle Energy Code saw increased strictness in airtightness requirements with the maximum allowable leakage rate shifting from 0.4 to 0.3 cfm per square foot. That may not seem significant at first glance, but consider this: as of this post, multifamily buildings tested by RDH had a 92% pass rate at 0.4 cfm […]

New Construction

In the simplest terms, building airtightness refers to a building’s resistance to air leakage—air flowing both in and out of the building—through areas of the building enclosure not intended to allow air flow. The idea of air entering or exiting a building may not seem like cause for concern, but in reality, airtightness is an […]

Energy-efficient design in buildings is helping reduce the carbon footprint of our communities and manage future energy costs in North America. A key element in achieving energy efficiency is to measure and verify energy savings and emissions reductions, ensuring that low energy buildings continue to perform: enter RDH. In 2013 RDH was retained to undertake […]
