Featuring: Nat Coughlin, L.D. Russo - Presenting lessons learned from the Waring School in Beverly and the Hillsdale Center in Newburyport. Ed Sople, Dellbrook JKS - Presenting a case study of a multifamily project, the Loop at Mattapan Station. Aaron Gunderson, PHMass - Presenting on principles, features, and common construction details of Passive House projects. Read More

This session will review the Passive House building standard and certifications, highlight design and construction principles, showcase examples and case studies of built projects, and explain the available incentives from Mass Save for projects and training.  All experience levels welcome for this introductory course covering various building types including mid to high rise multifamily, low rise and single family, affordable housing, and commercial offices. Great for architects, builders, contractors, developers, and policy makers who are either new to Passive House or looking for a refresher on the up-to-date standards and incentives as of 2021. Live virtual session with audience Q&A.   Read More

Proper ventilation is essential to making Passive House buildings work and providing high levels of air quality and comfort. This presentation discusses integrating comfort control systems with variable refrigerant flow (VRF) systems.  Presented by: Mike Woolsey, Certified Passive House Designer and building systems expert at Swegon North America JS Rancourt, Principle at DXS New England, VRF HVAC specialist   Read More

  Electrification is the buzz word du jour for decarbonization, and it’s pushing policymakers to rethink how they structure everything, from local codes, to energy models, to how they incentive programs focused on high performance buildings. Passive House has always provided a more careful accounting for ‘source energy,’ looking closely at which fuels power which appliances and HVAC equipment, noting that not all source energy is equal. This presentation will delve into how the Passive House standard is structured to support both electrification and decarbonization. We’ll delve into the back end of the Primary Energy Renewables framework. We’ll look at how these renewable source energy factors are derived, how they’re applied to the various active components in buildings. Lastly, we’ll look at how these work for New England using a specific project in PHPP. Presented by: Bronwyn Barry, North American Passive House Association Board President Dylan Martello, Senior Building Systems Consultant, Steven Winter Associates Read More

Presented by Bronwyn Barry, North American Passive House Network Board President This presentation will take a macro view of policies applied to building development, highlighting opportunities available to policymakers to accelerate decarbonization using the Passive House standard. Ms. Barry will look at where and how the Passive House development process fits (or doesn’t fit) within conventional code frameworks. This macro view of the development journey typical for most buildings will identify specific leverage points available to policymakers, highlighting how and where Passive House may be leveraged to drive higher performance, not just for projects targeting Passive House, but for all buildings. She’ll close by reviewing specific policies and programs currently being utilized in North America as onramps to Passive House, sharing why they’re working and how these programs may be adapted for similar local success.

This interactive online four-session workshop series draws on project experience to demonstrate cost-effective planning and design of affordable, low-emission, mid-rise, multifamily, wood-framed housing. Featuring regional case-studies and strategies for Massachusetts and New England.  The solutions presented in this workshop are drawn from the hundreds of affordable multi-unit buildings constructed to the Passive House standard worldwide, because this is the largest cohort of affordable, low-emission, mid-rise, multi-unit housing. While these solutions are taken from multi-unit Passive House buildings, they are equally applicable to buildings constructed to other low-emissions standards. Likewise, while affordable housing projects dominate the case studies presented in this workshop, the patterns apply equally to market- and luxury-housing projects. The curriculum has been prepared by the Energy and Sustainability team at RDH, a team that is consulting to more than five million square feet of Passive House projects, in consultation with Passive House Massachusetts and Mass Save. The workshops will be presented by Monte Paulsen, a veteran Passive House trainer and leader of the RDH Passive House team. Recordings of all workshop sessions are available for a limited time. Register to watch now.  Workshop 1: Guide to a Pattern Language, Form Patterns, Costs, Discussion Workshop 2: Embodied Carbon, Assembly Patterns, Thermal Bridging Patterns, Incentives Workshop 3: Summer Comfort, Shading & Window Patterns, Cooling Patterns, Open Discussion Workshop 4: Ventilation Patterns, Electrification Patterns, Planning Process & Timelines, Wrap-up Discussion   Read More
