Proposed Session Description
It is no longer sufficient to provide high-performance envelopes without considering their broader impacts. Design teams must address the immediate impact envelope materials have on our planet. Thankfully, we have the tools needed to design enclosures using low carbon and biogenic materials.
This session investigates two academic projects in MA that employed double stud framing at scale to provide high-performance envelopes that are durable, vapor open, built of carbon-storing materials, and elegantly detailed. We will present both modeled and measured data for life cycle, energy performance, moisture content, and even beauty while discussing the design process that supported the final designs.
Diversity and Inclusiveness
This session does not address these equity issues directly.
Learning Objectives
Define divergent objectives and priorities for developing enclosure design responding to criteria of durability, cost, and climate impact.
Measure and compare exterior wall assembly durability, cost, and climate impact
Understand the vapor movement within a double stud cellulose wall in the New England climate
Identify tools for measuring the embodied carbon of a building, and of wall assemblies.
Has this session been presented before?
Yes
When and Where?
A drastically abbreviated version of this study has been presented at the Wadgy Anis Building Symposium.
Session Format
Interview or structured conversation among panelists
Presentation followed by facilitated discussion or breakout groups
Session Format Details
There's a lot of building science and collected data to share, but we're open to brainstorming how to make that more engaging and interactive if that's appealing.
Recommended Length
90-minute session

Diana is an international Ph.D. student from Mexico at the University of Massachusetts Amherst. She is in her third year of doctoral studies in the Building and Construction Technology Program (Department of Environmental Conservation) with an area of concentration in sustainable building systems. Her interests and research are concerned with high-performance and energy-efficient buildings with special emphasis on the building envelope of both residential and commercial structures. Diana’s experience in the energy sector and renewable energy technologies, coupled with the imminent threat of climate change, motivated her to focus on not only contributing to greener ways to produce energy but to contribute to its conservation and more efficient use in buildings. Low-carbon, durable, and high-performance buildings, as it relates to the above, have been the recent and primary focus of her work.
Christopher is an associate with Bruner/Cott Architects. He uses architecture as an act of environmentalism, innovating sustainable and low-carbon approaches for both new buildings and historic structures to address climate change. It is Christopher's goal to make a positive impact on the built environment, while sharing his experience with future designers.

Full Description
While building professionals are becoming more aware of the importance of embodied carbon in our overall climate crisis, it still falls secondary to operational performance goals in most design conversations. Frankly, carbon offsets still offer cheap (read: undervalued) solution. Deep wall cavities filled with cellulose offer affordable strategies for high levels of insulation with low carbon, or carbon-storing materials; however, durability issues related to the control of inter-wall moisture persist. Hygrothermal simulation tools have been helpful in understanding the physics of these walls; however, internal (occupancy) and external (weather) factors have huge impacts on real performance. Data collection and analysis is critical to increasing our collective knowledge on this subject and is critical to addressing our low-carbon building future.
