The building enclosure and construction community is becoming increasingly cognizant of its contribution to global carbon dioxide emissions and has started taking large steps towards reducing the impact of the built environment on the natural environment. These steps are reflected in programs like the 2030 Challenge, the Living Building Challenge, Passive House design, and in legislation through national energy code standards and individual state code adoptions.

This presentation will explain the science behind the building enclosure and how seemingly small changes in the building enclosure design can have out-sized impacts on the long-term energy efficiency of a building. We will also discuss recent progress in the International Energy Conservation (IECC), changes in the 2022 California Title 24 which came into effect January 1, 2023, and how these changes will impact building enclosure design.

A well-designed building enclosure is a foundational part of any energy efficient building. We hope that after this presentation you will have a better understanding of the building science principles that inform energy efficient enclosure design. This will include a discussion on common assemblies, materials, and interfaces.

About Our Speakers

José Estrada PE is a principal with 4EA Building Science and has more than a decade of experience in enclosure consulting. His project portfolio varies in type and budget, including multi-million-dollar single buildings to multi-billion-dollar full block redevelopments. His experience includes projects in the USA, Canada, Mexico, Israel, and China.

José is passionate about building science, unitized facade systems, and sustainability. When not working on a project, he enjoys researching global trends in the design and construction industry, writing articles on trending topics, and presenting at conferences and industry events.

Clarissa Binkley P.ENG., B.A.SC., M.A.SC. is the Office Director of 4EA’s Oakland operations and has more than a decade of experience in building enclosure work.
Her building science experience began from the energy perspective, studying trends in building energy use and correlations ranging from the form of the enclosure, to efficacy of retrofit and rehabilitation projects, to occupant comfort and behavior.

Clarissa’s consulting experience includes both new construction and existing building projects in climate zones across North America. She has been involved from the conceptual stage up to project closeout, providing building envelope design and design reviews, construction field reviews and in situ testing, forensic investigations and monitoring, and building enclosure commissioning.
