Event description

Description

Total lifecycle carbon impact includes two primary considerations: operational carbon and the embodied carbon of materials used to construct the building. With Passive House, we have a proven approach to minimize operational carbon; however, embodied carbon is not a required consideration with Passive House. This is an additional opportunity if the goal is indeed to mitigate the climate crisis.

Recent research has shown embodied carbon is a higher percentage of the total lifecycle carbon impact by 2050 in the Pacific Northwest (PAE Engineers 2018). This is especially true as we move towards a decarbonized grid and all-electric buildings. Embodied carbon also becomes an even larger percentage of total lifecycle carbon as we decrease operational carbon through the Passive House approach. To summarize the urgency of this issue, a Passive House built with foam insulation has over three times the total lifecycle carbon impact of a code building (Magwood 2017).

On the positive side, if we use carbon negative insulation materials, and sustainably harvested wood framing, we have the opportunity to deliver carbon negative buildings from day one. In addition, these carbon negative materials also help us improve comfort and health while maximizing the durability of the building.

Four learning objectives:

1. Outline known challenges and advantages in the design and construction of a low-carbon building.

2. Measure embodied carbon value of common building materials and their impact on building lifecycle.

3. Provide critical analysis of total lifecycle carbon impact.

4. Describe cost-effective strategies to minimize embodied carbon while also maximizing health, comfort, and durability.

Speakers:

Lucas Johnson from 475 High Performance Building Supply will be our main speaker. Lucas is a building scientist who has worked as a builder, utility program manager, enclosure systems consultant, and cleantech venture capital consultant to deliver Zero Net Energy, Passive House, Living Future, and even two of his own standards: SUN Buildings and Active House. He holds a degree in Physicochemical Biology as well as a Master of Environmental Science and EcoEntrepreneurship. His position at 475 is his dream job since he gets to share his experience by collaborating with architects, engineers, and builders to make their projects cost-effective, carbon negative, healthy, durable, and enjoyable.

Mike Horgan is a Certified Passive House Consultant; zero-energy design-builder licensed in both MA and CA living in San Luis Obispo; founder of Cairn Collaborative Construction Consulting. Mike will discuss transitions needed from builders and architects away from conventional practice in order to achieve higher-performance homes and the ease with which these transitions are made.

Beate Kirmse is a Certified Passive House Consultant and your host. Beate and her husband Bern Galvin just finished the first step of a step-by-step EnerPHit project of their 1948 Ranch-style home. She will discuss her motivation behind the project, lessons learned and how the implementation of air tightened walls, exterior insulation, and a ductless heat recovery ventilation system has improved their comfort and thus the quality of their life!

After the workshop ends at 5 PM, we will have plenty of time to chat over snacks and drinks. We will conclude the event at 7 PM.
