How do we create buildings that use energy efficiently? Traditionally, efforts to green the built environment have centered on the physical infrastructure, often overlooking the relationships between people and space. The emergence of the technological era has ushered in "Smart Buildings." that employ machine learning and automation. These innovative structures are designed to operate with impressive energy efficiency, however, they are largely disconnected from their occupants. What if buildings could be made smarter and more sustainable by engaging with their occupants?
Architects of today face a common task that defies intuition – how to balance building performance and strict carbon targets against cost. Sustainability in design is certainly a worthy and necessary goal, but the amount of options can be overwhelming and the costs prohibitive, especially in the eyes of owners. How can designers best convince their clients to integrate sustainability into a project? Keeping costs low and backing up decisions with fact-based analysis are solid first steps.
In a study recently published by AIA, less than 13% of architectural firms have incorporated building performance as part of their practice. With buildings contributing 40% of total carbon emissions leading to climate change, just 25 projects are roughly equivalent to planting 1 million trees each year. In addition to that, teams that are able to showcase data-driven and performance-driven decision-making and feature an energy analysis in every pursuit are able to increase fees and generate more revenue. Although integrating building performance sounds like a no-brainer, it proves to be difficult at many firms, because in addition to the practical changes, it requires a culture shift. That culture shift can only happen if the tools are easy to use, accurate, and mesh well with current workflows. Right now is the perfect time to tackle these culture changes due to a few reasons:
It’s a topic that cannot be avoided for any longer. The ongoing Paris Climate Conference has seen an unprecedented amount of participation - even before the summit began, over 150 countries submitted national plans of action to the United Nations - and there seems to now be a global consensus that we must cut back on our energy use and reliance on carbon polluting fossil fuels, or risk causing irreversible damage to our planet. By the end of the conference, an agreement will likely outline energy-reducing strategies by which all countries must abide. For architects, this means fundamentally changing the ways we design buildings and determine their success. Traditional building and construction methods consume large quantities of natural resources and account for a significant portion of the greenhouse gas emissions that affect climate change. In the United States, the building sector accounts for 41 percent of the country’s energy usage, according to the U.S. Green Building Council.
But this information is hardly new, and thankfully, our profession has been preparing for this change for some time. In 2006, the American Institute of Architects became the first adopters of the 2030 challenge, a call for all new buildings, developments, and major renovations to reach carbon-neutrality by 2030, with milestone goals of reduced dependence at 10-year intervals along the way. Each year, the AIA releases a progress report outlining the current standing of energy consumptions and take-aways from their findings. This year’s key conclusion? We must start integrating energy modeling techniques earlier into the design process.
