Companies, organizations, and firms working in the building, construction, and design space have a unique opportunity and responsibility. Collectively, we are contributing to nearly 40% of energy-related carbon emissions worldwide. While the goals, commitments, pledges, and promises around these challenges are a step in the right direction, no one entity alone will make major improvements to this daunting issue.
We need to come together, demonstrate courageous change leadership, and take collective approaches to address the built environment’s impacts on climate. Collectively, we have a unique opportunity to improve people’s lives and make positive, measurable changes to impact:
Buildings, homes, and hardscapes
Consumer, commercial, and public sector behavior
Our Collective Carbon Emission Challenge
According to many sources, including the U.S. Green Building Council (USGBC), the built environment accounts for 39% of global energy-related carbon emissions worldwide. Operational emissions from buildings make up 28% and the remaining 11% comes from materials and construction.
By definition, embodied carbon is emitted by the manufacture, transport, and installation of construction materials, and operational carbon typically results from heating, cooling, electrical use, and waste disposal of a building. Embodied carbon emissions are set during construction. This 11% of carbon attributed to the building materials and construction sector is something each company could impact individually based on manufacturing processes and material selection.
The more significant 28% of carbon emissions from the built environment is through the operations of building. This is a dynamic that no company can influence alone. Improving the energy performance of existing and new buildings is a must, as it accounts for between 60-80% of greenhouse gas emissions from the building and construction sector. Improving energy sources for buildings and increasing energy efficiency in the buildings’ envelope and operating systems are all necessary for future carbon and economic performance.
the more significant 28% of carbon from the building operations sector is something no company can influence alone. Our future progress depends on today’s actions.
This is an industry-wide issue, and we need an industry-wide solution that can be replicated in different communities and even different countries.
There are numerous collectives that are driving awareness, understanding, and action at the governmental and organizational levels, largely inspired by the Paris Agreement enacted at the United Nations Climate Change Conference of Parties (COP21) in 2015. The Architecture 2030 Challenge seeks to reduce climate impacts from carbon in the built environment; it inspired several commitment programs, including the AIA 2030 Commitment.
In recent years, narrow approaches to addressing carbon have prevailed, including the rampant net-zero carbon goals for individual companies, firms, and building projects. Though these efforts are admirable, many lack real roadmaps to achieve these goals. In light of this, the US Security and Exchange Commission has issued requirements for companies, firms, and others to divulge plans to achieve lofty goals and ultimately report to the government on progress in reaching targets. These individual actions will only take us so far.
Additionally, the regulatory environment continues to evolve and drive change. If we consider the legislative activity in Europe, which frequently leads the way for the rest of the world, we can all expect carbon taxes to become the standard. There are currently 15 proposed bills that would implement a price on carbon dioxide emissions. Several states have introduced carbon pricing schemes that cover emissions within their territory, including California, Oregon, Washington, Hawaii, Pennsylvania, and Massachusetts. Currently, these schemes primarily rely on cap and trade programs within the power sector. It is not a matter of if but when carbon taxes will become a reality in the US.
Lastly, and perhaps most significantly, the impacts of climate change and a warming Earth are present in our changing weather patterns. Weather around the world—especially during the summer of 2022 and the increasing severe storm activity through North America in 2023—is quickly convincing people that climate change resolution is needed immediately.
Theory of Change
Climate issues are immediate and immense. Our industry is so interdependent that we can’t have one sector delivering amazing results while another is idle. Making changes and improvements is an effort bigger than any one organization could manage. Working together, we can share resources and ideas in new ways. We can create advantages and efficiencies in shared R&D, supply chain, manufacturing, transportation, design, installation, and more.
Collaboration will bring measurable near-term positive change that would enable buildings and homes to become net-positive beacons for their surrounding communities. We can create a network where each building/home has a positive multiplier effect. The network is then compounded by linking to other elements that contribute to a community’s overall carbon footprint.
Proof of Concept: GAF Cool Community Project
An estimated 85% of Americans, around 280 million people, live in metropolitan areas. As the climate continues to change, many urban areas are experiencing extreme heat or a “heat island effect.” Not only is excess heat uncomfortable, but heat islands are public health and economic concerns, especially for vulnerable communities that are often most impacted.
Pacoima, a neighborhood in Los Angeles, was selected by a consortium of partners as a key community to develop a first-of-its-kind community-wide research initiative to understand the impacts various cooling solutions have on urban heat and livability. Pacoima is a lower income community in one of the hottest areas in the greater Los Angeles area. The neighborhood represents other communities that are disproportionately impacted by climate change and often underinvested in. Ultimately, the goal of the initiative is to reduce surface and ambient air temperatures throughout the community.
About the GAF Cool Community Project:
Community Engagement and research initiative to understand how cities around the world can address Excessive urban heat at a community level.
Multi-phase project launched in July 2022 across a 10-block area in the Los Angeles neighborhood of Pacoima.
Public-private partnership includes GAF, the Global Cool Cities Alliance, Climate Resolve, and the city of Los Angeles.
Additional contributors include a research team; local non-profits and community organizations; local leaders and organizations including Urban Semillas and Pacoima Beautiful; and Monica Rodriguez, Los Angeles City Councilwoman, 7th district.
Implementation: Phase one included the application of GAF StreetBond® cool, solar-reflective pavement coatings on all ground-level hard surfaces, including neighborhood streets, crosswalks, basketball courts, parking lots, and playgrounds. The project also includes a robust community engagement process to support local involvement in the project, measure qualitative and quantitative impact on how cooling improves living conditions, and ensure the success of the project.
Phase 2: After 12 months of monitoring and research, GAF and partners will evaluate the impact of the cool pavements with the intent to scale the plan to include reflective roofing and solar solutions.
This ongoing project will allow us to evaluate for proof of concept and assess a variety of solutions as well as how different interventions can work together effectively (i.e., increasing tree canopies, greenspacing, cool pavements, cool roofs, etc.). Through community-wide approaches such as this, it’s possible that we could get ahead of the legislation and make significant innovative contributions to communities locally, nationally, and globally.
With collaboration from leaders across the building space and adjacent sectors, we believe it is possible to drive a priority shift from net neutral to net positive. Addressing both embodied and operational carbon can help build real-world, net-positive communities.
We invite all who are able and interested in working together in the following ways:
Join a consortium of individuals, organizations, and companies to identify and develop opportunities and solutions for collective action in the built environment. The group will answer questions about how to improve the carbon impacts of the existing and future built environment through scalable, practical, and nimble approaches. Solutions could range from unique design concepts to materials, applications, testing, and measurement so we can operationalize solutions across the built environment.
Help to scale the Cool Community project that was started in Pacoima. This can be done by joining a collaborative and collective approach to climate adaptation for phase 2 in Pacoima and other cities around the country where similar work is beginning.
Collaborate in designing and building scientific approaches to determine effective carbon avoidance—or reduction—efforts that are scalable to create net-positive carbon communities. Explore efforts to use climate adaptation and community cooling approaches (i.e., design solutions, roofing and pavement solutions, improved building envelope technologies, green spacing, tree coverage, and shading opportunities) to increase albedo (reflection of solar light and subsequent heat) of hard surfaces. Improve energy efficiency to existing buildings and homes and ultimately reduce carbon at the community level.
