Test your skills in Seal or No Seal: The Building Envelope Challenge! This fast-paced, interactive competition uses Menti’s quiz platform to tackle airtightness, insulation, and thermal performance dilemmas. Compete individually, climb the leaderboard, and gain actionable insights on high-performance building envelopes—all while having fun!

We all agree that everyone deserves to breathe healthy air inside their home. But are current HVAC practices delivering healthy air to occupants? Join us for an insightful Town Hall discussion as we explore the state of mechanical whole-house ventilation. With over nine decades of combined experience in home performance and construction, three industry leaders […]

When it comes to improving a home’s Energy Rating Index (ERI), upgrades like continuous insulation, triple-pane windows, and heat pump water heaters are common go-to solutions. But what if a more cost-effective path to significant ERI reduction has been hiding in plain sight? In this session, we’ll compare the ERI impact of traditional energy efficiency […]

Amongst the many challenges of building tight, energy-efficient homes is integrating and properly sizing HVAC and hot water equipment that balance the heating and cooling energy needs against dynamic indoor and outdoor thermal fluctuations. With the drive to limit energy losses through the building envelope, maintaining optimal indoor comfort and air quality requires more advanced […]

Improved filtration is becoming more recognized as an essential part of overall indoor air quality. HVAC filters can be an important factor in lowering indoor air particulates.  This hands-on session will consist of a short lecture followed by measuring pressure drops of various filters and various airflow volumes.

Join Dan in his return to the Northwest for a lively demonstration on the options, pros, cons, and considerations with different ventilation strategies. Dan will address what happens in homes with positive pressures vs negative pressures. We’ll discuss the processes and equipment, code compliance and cost, and finally what we can market and what will appeal to residents. Attendees […]

When sized and commissioned right, a heat pump spends most of its time running at a fraction of its total capacity. Variable-speed heat pumps operate over a wide range of speeds to adjust their capacity but are 10-50% MORE efficient when running at less than full output. This session will give insights on how heat […]
