Hope is ignited when solutions can be seen clearly and positive action taken immediately. We will ignite and fuel hope by presenting the very real and immediate carbon drawdown reservoir that exists in constructed or renovated buildings - the result of actions taken by everyday homeowners, builders, engineers, and architects. Surprisingly, some of the biggest impact solutions are found in the multitude of low-rise buildings, both residential and public/commercial, that are built and the many more that are renovated each year in North America. Builders for Climate Action, founded 2019, focuses on rapidly moving the building trades to apply the knowledge of embodied carbon and its impact on a building's net emissions, and to expand the use of carbon-storing materials for buildings. We can store atmospheric carbon in the buildings we create by the use of plant-based and other carbon-storing healthy materials (the topic area for this presentation), leading to carbon drawdown from the atmosphere and the reversal of climate change. This sea-change has already begun and must expand rapidly if we are to reverse the damage done to the climate.
40% of global carbon emissions are the result of constructing buildings. This staggering figure locates a critical pivot point in the construction sector that we can and must transform immediately. There was a total of approximately 2.1 billion square feet (198 million m2) of residential construction built in the US in 2016. By our intentional actions, buildings can become the planet's sixth carbon sink, and making such "drawdown buildings" is much less complicated than you might think. Builders for Climate Action is developing a carbon calculator tool for all to use, a specification/guide book, cooperative supply chains for biogenic materials, and carbon curriculum for trade education, among other initiatives. The democratic potential of making change at the level of low-rise buildings goes beyond simply making buildings that are drawdown reservoirs. It connects everyday tradespeople and residents to concepts like the planetary carbon cycle, and how we can and must come into positive interrelationship with soil, forests, grasslands, and agriculture to heal the damage we've done. The opportunity to develop networks of information, materials, and trade in a democratic, cooperative and socially-just manner mirrors the positive interrelationship approach on all levels - people with people, people with planet.
The presenters share diverse backgrounds. Representing both a cooperative design/build company and a sustainable building school, they are builders, designers, educators, and researchers, with decades of experience at the leading edge of high-performance natural building. They have been responsible for the design and construction of numerous carbon-storing buildings that are affordable, code-compliant, high-performance and healthy. Sharing both extensive research into embodied and operational carbon emissions, as well as key case studies, they will ground the theory of carbon capture and storage in buildings with practical, real-world examples that prove that the ability to store upwards of 50 tons of CO2 in the materials of relatively small buildings is something that can and has been done. Unlike more traditional panels, this dynamic presenting team builds off each others' strengths and enthusiasm, weaving voices and perspectives seamlessly throughout an energizing and engaging presentation.
To augment and support the theory, data, and case studies, the presenters will show examples of biogenic, carbon-storing materials, ranging from the easily accessible to the more cutting-edge. The presenters will share the knowledge they have developed for creating buildings that meet the highest goals of occupant health, affordability, appropriate sourcing and carbon storage. The audience will be able to see how materials selected to meet these goals can be assembled into building components (suitable for walls, roofs, and floors) that are both simple and effective. By addressing the Materials petal in the topic area of Healthy Materials, creating Living Buildings or Zero Carbon Certified buildings that store large amounts of carbon will seem altogether possible at the end of this session.
