Quality Assurance for Low-Pressure Disposable Foam Systems
Enclosure, Residential- Henri Fennell, Jr., HC Fennell Consulting, LLC
One and two-part portable foam systems ('kits and cans') are used by do-it-yourselfers, contractors, and spray foam installers alike. These versatile disposable products allow users to do small or intermittent applications where bulk foam installations are not cost effective, or in remote locations where using bulk foam is not possible. How these systems work and why they can be problematic is discussed in detail. Instruction about how to properly prepare and use kits and cans is provided, along with photos and demonstrations of accessories that improve their efficiency and effectiveness, while maintaining product quality and convenience.

The presentation will focus on explaining what’s involved in a dew point (condensation point) calculation in a proposed basement, wall, or roof system and the very basic practical approach for doing the calculation. More advanced methods will also be covered. The attendee should come away with a basic understanding of the risk of failure involved with constructing high-performance walls for cold climates and why careful consideration is needed if building science rules of thumb, or detailed code prescriptive standards, are not followed.

Construction Phase Carbon Impact
Commercial, Commercial- Megan Nedzinski, Vermont Integrated Architecture, PC
- Amy Sheldon, Landslide, Inc.
- Ashar Nelson, Vermont Integrated Architecture
Our region has made great strides in advancing high-performance, zero-energy building practices; however, construction projects rarely quantify, or even consider, carbon during construction. Current Vermont policy initiatives and programs continue to push projects to meet 2050 climate goals (Act 250, Tier III programs, etc.) while project delivery decisions remain blind to community and environmental impacts, staying focused on time and money. Presenters will share insights into current policy initiatives and programs, lead an interactive discussion of key construction phase carbon considerations, and demonstrate how greater consideration of these key elements could help shift owners’ construction stage decision making toward positive change in a more holistic way.

When Persistence Pays Off: A retrospective of early adoption of ASHRAE Guideline 36
Commercial, Commercial- Henry Stehmeyer, Cx Associates
ASHRAE's Guideline 36 standard HVAC sequences of operations reduce engineering time, increase energy savings, improve indoor air quality, and normalize terminology and concepts between trades. Three years ago, UVMMC implemented these sequences at their Fanny Allen building. Now they have the results from that implementation, the energy savings, and the lessons learned. Come listen to our story, see the results presented by ownership and implementers. Learn how HVAC controls sequence refinement is an efficiency measure with big potential to move the industry toward efficiency goals. We'll show you a new HVAC controls approach and how it produced persistent energy savings.

Fixing Existing Homes (Part 1)
Enclosure, Residential- David Keefe, Efficiency Vermont / VEIC
In 2008, Vermont adopted a goal to weatherize 80,000 homes by 2020, with average 25% savings. We are woefully behind. Currently we fix roughly 2,000 homes per year, with average savings of less than 25%. In this session, the presenter will outline how this work is done, what opportunities exist for doing more of it, and how we can do it better. We’ll start with some lessons about indoor air quality, carbon monoxide, ventilation, and moisture learned over the 30 or so years that the weatherization industry has existed. We will discuss the state of the diagnostics art, the tools and techniques we use to figure out what to do. Then we will move to the hands-on work itself, practical things we are doing in Vermont homes to make them work better. We will wrap up with some challenges that the industry faces, including staffing and sales. This session is appropriate for those already doing this work, those considering getting into it, and anyone who wants to better understand how it is done.

Solar Fire Investigation Analysis: The Unintended Consequence of Reflective Low-E Glass Technology
Crossroads, Commercial- Curt M. Freedman, CMF Engineering, Inc
Low-E glass windows are also referred to as insulated glass units (IGU). In this session, the presenter will explain how a combination of factors can result in the IGUs becoming concave and parabolic in shape. The reflective metallic coating causes the IGUs to reflect concentrated sunlight with focal lengths of 15–60 feet. It has been determined that the concentrated reflected light of three times direct sunlight could easily melt vinyl siding, and 12 times direct sunlight could ignite fires, with corresponding absorbed blackbody temperatures of more than 532 degrees F.

Ground source heat pump (GSHP) – or geothermal heat pump – systems are the most efficient heating and cooling systems available and an effective strategy for decarbonizing buildings. GSHPs can eliminate fossil fuel heating and domestic hot water systems, greatly reduce CO2 emissions and electric peak demand, and can help our state achieve the goals of our Comprehensive Energy Plan. Over the past decade, innovative new business models have emerged and hold out the promise to move geothermal from a boutique technology to an affordable HVAC solution for all. In Vermont, there are barriers to address to improve affordability and develop the supply chain. Can we scale geothermal in Vermont like we are seeing in other states and Canada?

Encouraging Building Airtightness: A New Five-Story Building in Maine
Enclosure, Commercial- Frederick McKnight, Turner Building Science and Design, LLC
In 2019, the presenters completed a building enclosure commissioning program on a five-story building in Bangor, Maine. The building is a new structure housing offices and a computer center. The design intent was to build a very energy-efficient building. The structure was tested for airtightness. The goal was 0.25 CFM/sq. ft. at 75 Pascal pressure difference, and the tested result was 0.04 CFM/sq. ft. The design included a modern wall structure, a roof with minimal penetrations, and a poured concrete basement (walls and floors). The enclosure assembly was composed of standard, readily available components. This session explains how these results were accomplished.

Healthy Homes & Home Performance: Making the Homeowner Connection
Enclosure, Residential- Peter Troast, Energy Circle
One of the greatest challenges the home performance industry faces is how to connect consumer demand for healthy homes with private market opportunities for home performance improvement. The demand for and awareness of healthy homes continues to grow, but few homeowners connect health issues with the systems that make up their home. The presenter will explain the trajectory of the healthy homes movement within home performance, and unpack how contractors can bridge this communication gap with homeowners, as well as cover the foundations of a healthier home business and marketing strategy.

The Ghosts Among Us – Reducing Air Infiltration from the Darkest Recesses to Dramatically Improve Comfort and Energy Performance
Enclosure, Residential- Mary Jane Poynter, VEIC
- Allison Ross, VEIC
- Karen Bushey, VEIC
Building air tightness is a 30-year-old concept but buildings have not always maximized the long-term benefits of focusing attention on air sealing details. Air tightness in multifamily and commercial buildings in Vermont has improved over the last 15 years. Both energy modeling and actual energy usage has shown that lower air leakage rates can have a bigger impact on building energy usage and system sizing than adding more insulation to the building walls and roof. This presentation will include blower door test data and demonstrate how buildings have achieved increasingly tighter envelopes. We will present energy modeling data to illustrate air sealing and insulation impacts on energy use and discuss the top five strategies to ensure tight building envelopes.
