Track A: EMBODIED CARBON and CLIMATE, Co-Sponsored and Moderated by the EcoBuilding Guild

Quantifying the Carbon Footprint of Every Project - Stacy H. Smedley, Director of Sustainability Skanska USA Building - This session will describe the recent developments in tools and best practices for Whole Building Life Cycle Assessment and attaining Net Zero Carbon certification.

Refreshing RefrigerantsAllan Montpellier, PAE, David Mead, PAE & Thomas Schaer, SHED - What are refrigerants’ true carbon impact on the natural environment? A central component in current HVAC system design, refrigerants can be used as energy-saving tools. However, if released into the environment, many refrigerants have thousands of times the impact as CO2 and contribute directly to global warming. The presentation will draw from research done with Paul Hawkins’ Project Drawdown on the top solutions to reduce greenhouse gas emissions where refrigerant management came in as the number one solution.

Passive House in a Changing Climate - Eric Catania, RDH Building Science - Passive House buildings are finely tuned for the climate zone in which they are constructed. But how will these buildings perform when the climate changes? This presentation will introduce the study of future climate scenarios, will introduce sources of data for predictive future climate files, will review a procedure for creating predictive PHPP climate files, and will present an example of how the performance of a specific Passive House project may vary according to future climate scenarios.

Avoid The Carbon Rebound: How Passive House Can Create Higher-Carbon Buildings Than Conventional Methods - Lucas Johnson, 475 High Performance Building Supply - With Passive House, we have a proven approach to minimize operational carbon; however, embodied carbon is not a required consideration. This is a missed opportunity if the goal is indeed to mitigate the climate crisis.

 

Track B: BUILDER TRAINING

Envelope Workshop -Scott Kosmecki of Hinge Build Group & Josh Salinger of Birdsmouth will moderate this workshop style discussion of Passive House experts in our region to qualify the best assemblies in use for our climate zone that reach Passive House standards.   The criteria will be based on Price, Trade Buildability and Risk Reduction.  At the end of this workshop we should have a set of example assemblies to share with the Passive House community.

What to do with All Those Crappy Old Buildings? Learnings from a NEEA Pilot on Small Commercial Buildings in the Pacific Northwest - Christy Love, RDH Building Science - Investigating a multi-year pilot study sponsored by the Northwest Energy Efficiency Alliance (NEEA) that was undertaken to predict and measure the energy savings and air quality impacts from this conversion method in (8) small commercial buildings throughout the Pacific Northwest.

Passive House Inspired Codes and Policies: How Leading Jurisdictions are Shifting Their Approach in order to Meet Ambitious Energy and Carbon Reduction Goals - Mark Lyles - New Buildings Institute, Lisa Westerhoff - Integral Group (Vancouver) - Advanced energy codes and policies are one of the biggest opportunities for cities and states to reduce energy consumption and carbon emissions associated with the built environment. However, based on the current trajectory of currently adopted energy codes it is becoming increasingly clear that they are not requiring the levels of efficiency needed to meet many of the energy reduction goals adopted by leading jurisdictions and organizations such as Architecture 2030. A number of jurisdictions including Massachusetts, New York and British Columbia have incorporated passive house principles into their Stretch or Step codes as a more energy efficient alternative code pathway. This session will examine these principles and how they are are being applied through different energy and building policies to dramatically improve building performance and meet energy and carbon reduction goals.

 

Track D: MECHANICAL TRAINING

Educating the Next Generation - Alison G. Kwok, PhD, University of Oregon - This session will garner lessons learned from integrating the CPHC/passive house principles into the curriculum at three US universities (University of Oregon, Miami University [Ohio], and Prairie View [Texas]) and will describe exercises, activities, successes and challenges/hurdles.

Indoor Air Quality and HVAC Strategies for High Performance Healthy Homes - Greg Davenport, Mitsubishi Cooling and Heating - Homeowners, home builders, and HVAC contractors rarely put healthy indoor air quality and energy efficiency before the tangible elements of a home.
