Passive House: The Path to (PHIUS) Certification

This presentation demystifies the certification process by introducing key players, mapping critical milestones and reviewing concepts and tools that come up along the way.

What to Expect When You're Expecting a Passive House

This two-part workshop focuses on the technical aspects of Passive House verification and shares lessons learned along the way.

Best & Worst Practices of Air-Sourced Heat Pumps

These two sessions go in-depth on designing, installing, and operating ASHP's in retrofits, new code buildings and Passive House buildings.

Passive House 201: A Technical Look

This course goes into greater depth regarding the challenges and successful strategies employed to achieve the Passive House design criteria.


Why Passive House is Essential for Net Zero Energy

Passive + Renewables = Net Zero Energy. It is a simple equation that is not well enough understood or utlilized. In this presnetation, we intrdouice the concept as a theme for 2021. Then guest speaker Ken Levenson (NAPHN) gives his take on the concept and shares lessons learned. Guest speaker Tim McDonald (Onion Flats) then showcases a Net Zero Passive House project of his. We then end with Q&A and discussion

Passive as the Platform for Net Zero and Healthy Buildings Roundtable

Join us for a roundtable discussion on the role of Passive House in achieving net-zero emissions, electrification, and improving indoor health and air quality, including ongoing policy initiations like the EZ Building Code and Net-Zero Roadmap Bill. Will discuss how Passive House provides a platform for these transitions and fuels our efforts to to dramatically reduce the climate impact of buildings. Learn what local groups are working on, how PHMass can support them, and how we can all work together to create a healthy, comfortable, and carbon-free built environment.

Passive House Incentives, Policy, and Code Changes in Mass

In our December meeting we discussed the ongoing update process to the state’s PH incentive programs as well as the effort to update the Stretch Building Code to include Net-Zero and Passive House.

Internal & Solar Heat Gain in Multifamily: Passive House Solutions

For our July Virtual Meeting we welcomed special guest Dylan Martello (Senior Building Systems Consultant, CPHD, Steven Winter Associates) for a presentation on Internal & Solar Heat Gain in Multifamily Buildings: Passive House Solutions. Watch now with Q&A sections included.

Passive House Incentive & Feasibility Study Overview and Case-Studies

Representatives and participants of the Mass Save Passive House Incentive Program discuss in detail the process of going through the program, including conducting Feasibility Studies, Charrettes, and Energy Modeling, as well as the certification and approval process and incentive payment and net performance bonus calculations.

Passive House Builders Workshop: Martha’s Vineyard

This workshop produced for the Martha's Vineyard Builders Association and the Island Housing Trust features Passive House Builder Mike Dutra discussing the ins and outs of constructing homes and buildings to the Passive House standard.

Cost-Estimating for Passive House

Recorded at our January member meeting, this presentation features Ken Neuhauser and Wes Stanhope of Building Evolution Corporation, Ed Sople of Dellbrook JKS, and Julie Klump of POAH, discussing their approach to estimating costs on a large Passive House project.

Innovations in Low Carbon Materials

This December we welcomed a collection of speakers presenting on Innovations in Low-Carbon Materials. Featuring:
Tom Chase, from New Ecology, providing an overview of embodied carbon in buildings (at 0:00).
Elise Strobach, from the Device Research Lab at MIT, discussing AeroShield, a super-insulating nano-glass material for use in energy efficient windows (at 13:30).
John Klein, founder of John Klein Design and a Research Scientist at MIT, presenting on Mass Timber at (at 24:00).
Rob Conboy, CEO of Glavel, discussing how they turn recycle glass into a cost-effective alternative to sub-slab foam insulation (at 37:30).

A Builder’s Approach to Passive House

Recorded at our November member meeting, this presentation features Steve DeMetrick discussing A Builder's Approach to Residential High-Performance and Passive House Construction. Steve is a Certified Passive House Builder and built the first PHIUS Certified Passive House in Rhode Island. He also an occasional contributor to the Journal of Light Construction and Fine Homebuilding as well as a former board member of PHMA. Find at more at DeMetrick Housewrights.

Passive House Affordable Design Workshop

This recorded session from Tim McDonald and David Salamon provides cost-effective strategies and a practical guide for affordable multi-family Passive House projects based on their experience leading the way on these types of buildings in Pennsylvania.

This video is available on the Mass Save Passive House Online Learning Center.

Passive House Training Tool

This new training tool was developed primarily for multi-family projects but may be helpful for other Passive House building types. The goal of the tool is to empower each project team to develop their own in-house trainings specific to their project and provide them with the resources to effectively deliver that training to tradespeople who may have never done a Passive House project previously.

An Introduction to MultiFamily Passive House

This one-hour webinar provides an overview of Passive House principles and how they relate to multifamily buildings. This presentation is designed for all members of the project team - general contractor, tradespeople and design team. We will review what's required for Passive House certification, characteristics of Passive House projects, recent multifamily examples from New England, and lessons learned from other project teams.

Multi-Family Passive House: Bringing Passive House to Scale

On May 13th, 2019, PHMA sponsored a discussion on the PHIUS standard and multi-family Passive House development with Katrin Klingenberg, Executive Director and Co-Founder of Passive House Institute US (PHIUS). The presentation covered a variety topics including Passive House within the larger context of Net Zero and Net Positive building, compatibility of the PHIUS Standard with multi-family building types, and review of PH principles.
