Houston expert calls for more innovation within the construction industry
The construction industry has the opportunity to drive positive change through the development and deployment of technologies influencing the way we work and live, ultimately affecting our environment, communities, and personal well-being.
Carbon emissions come from a handful of broad categories, including transportation, electricity production, and industry. According to the International Energy Agency, more than a third of all global greenhouse gases come from the building and construction industry. Concrete production alone contributes an estimated 8 percent of global carbon emissions. As a result, in Houston, we are vulnerable to longer, hotter summers, stronger hurricanes and once-in-a-lifetime storms. But I'm optimistic that there is opportunity for our industry to come together and reverse the current trajectory.
We must continue developing and deploying new technologies and best practices to reduce emissions. By using data to understand the environmental implications of the materials we use, we can make adjustments that are beneficial to both our clients and the environment.
One such example is the Embodied Carbon in Construction Calculator, known as "EC3." Skanska USA developed the open-source, freely available software in collaboration with Microsoft and C Change Labs. The tool democratizes important building data and allows the construction industry to calculate and evaluate carbon emissions associated with various building materials.
Now hosted and managed by Building Transparency, a new 501c3 organization, the EC3 tool was incubated at the Carbon Leadership Forum with input from nearly 50 industry partners. Like the tech industry, we should promote knowledge-sharing among general contractors to drive innovation and sustainability.
The demand for this tool is growing because it's not only the right thing to do, but it also benefits our communities and drives stakeholder value. Now more than ever, clients want to be responsible global citizens and they know that adopting green building practices is attractive to their prospective workforce and their clients and customers.
In Houston, the current population of 7.1 million will double to 14.2 million by 2050. With that population growth comes the need for more housing, more office space and more transportation options. Last April, Houston enacted a climate action plan that sets goals aligned with those from the Paris accord — carbon neutrality by 2050.
Similar local plans have been and are continually being developed all around the world, a necessary step to address a global issue that impacts all of us. Like others, the Houston plan contemplates how to reduce carbon emissions that are the result of energy consumption which accounts for about half of Houston's greenhouse-gas emissions.
Innovations in energy efficiency can help drive down energy consumption. As conscientious global and local citizens, we also have to consider the emissions that are created by the raw materials that are used in construction. That's become a much easier process with the EC3 tool. Now architects, engineers and others involved in the design process can make data-driven decisions that can have significant impact on the carbon footprint — as much as a 30 percent reduction in embodied carbon — of a structure that are mostly cost-neutral.
Embodied-carbon reductions can be made simply by smartly using data. The EC3 tool is one of many steps toward innovative building practices and complements the important ongoing work done by the U.S. Green Building Council, which oversees LEED certification.
Opting for sustainable building practices is good for the environment, but it's also good for the people who will spend time in these spaces. Green building reduces the use of toxic materials, and studies have found that sustainable structures, such as schools, health care facilities and airports, have positive impacts on cognitive ability, seasonal affective disorder and overall happiness.
We are also seeing an influx of client requests for sustainable and healthy building upgrades, especially since the onset of COVID-19. These upgrades are changing the way we live and work while supporting infection control, from touchless elevators to advanced air filtration systems.
For example, innovation has been instrumental throughout the pandemic for the aviation industry's safe operation. Increased biometrics across airport touchpoints, flexible passenger gathering areas that include modifications to passenger hold rooms and departure lounges, and environmental monitoring and wayfinding technology to alert passengers of airport congestion points are a few new concepts airports are incorporating into builds to keep travelers healthy now and in a post-COVID world.
Overall, the construction sector will play an essential role in how we approach expanding the built environment over the next 30 years. Using data and striving for continual innovation, we have a great opportunity to come together as an industry and create real change that will benefit our collective lives and those of generations to come.-----
