The green building movement and arguably the larger discussion about sustainability have progressed in scope and understanding over the last three decades. Terrapin staff have been at the heart of this journey. In retrospect, this progression can be understood as three distinct levels of sustainability, each with their own focus, and with direct and indirect benefits that help to paint a picture of local, regional, global and industry priorities and trends.
Lowered Environmental Impacts
The coalescing of concerns about energy efficiency, indoor air quality and building construction impacts led to the formation of the AIA Committee on the Environment in 1990 and three years later the US Green Building Council. The mindset was focused on reducing harm to the environment. Rating systems such as LEED, BREEAM, and Green Star were developed as a way to validate environmental performance improvements. The scope and stringency of these systems has increased over the years and the broad adoption of these systems worldwide has had a profound impact on the commercial real estate industry.
This approach to project sustainability focuses on energy efficiency, water efficiency, renewable energy, indoor air quality, material sourcing, stormwater, site habitat and other environmental strategies. Examples of Terrapin’s contribution at this level of sustainability include the Jones Beach Energy & Nature Center, the California Academy of Sciences in San Francisco (LEED Platinum), and Merdeka PNB-118, a megatall tower in Kuala Lumpur (LEED Platinum anticipated).

Health and Well-being
The next stage of thinking began with the realization that while the focus of green building strategies leads to significantly reduced environmental impact and improved conditions for the occupants, it might be possible to concurrently focus on the health and well-being of the occupants. This approach looks at avoiding toxins and at providing high quality air, light, drinking water and food offerings, and has inspired certification systems including Fitwel and WELL.
From thinking about buildings as human habitat, and how to create conditions most supportive of productivity and well-being, came the desire to reconnect people to experiences of nature in the built environment; biophilia. Biophilic Design is a form of evidence-based design that draws on neuroscience, environmental psychology, and various sub-fields such as visual preference studies, alliesthesia, and psychoacoustics, to create spaces that measurably reduce stress, improve cognitive performance and enhance perception, mood and emotion. This approach encourages design teams to prioritize design interventions that optimize the environmental experience according to space and user type, as well as project goals. Examples of Terrapin’s work in biophilic design include Google’s biophilic design framework, the WELL certified headquarters of Interface Base Camp and the American Society of Interior Designers (ASID), the Westin GEN-5 hotel guest room prototype, the PDX Airport Terminal Core Redevelopment in Portland, OR, and Clif Bar’s industrial bakery in Twin Falls, ID.

Getting to net-zero is an important goal, however just putting a stop to carbon emissions in the atmosphere, or effluents in waterways, does not undo the existing damage to the environment. This type of thinking, which has inspired building standards like Living Building Challenge and the 2030 Initiative, rests on the realization that reducing environmental impacts are in the long run insufficient. This level of sustainability is evolving to encompass emerging priorities in health equity, environmental justice and community vitality, as well as urban planning considerations beyond the confines of a building’s walls.
This highest tier of sustainability focuses on recreating the services that healthy ecosystems provide, such as storing carbon, cleaning water, cycling nutrients, maintaining biodiversity and doing it in a way that supports equity and the dignity of people. This approach also enables a property or community to adapt to climate change and be resilient in the face of public health crises and geophysical events. This is regenerative design. Terrapin’s approach asks what the intact ecosystem of a development site would be doing, and then determines site-specific performance metrics for the design and long-term operation of the building or campus. This strategy includes both ecological and social engagement with/by the local community. Examples of these aspirational efforts are sustainability tools for Google’s 111 Eighth Avenue in New York City, Interface’s Factory as a Forest effort, and Buffalo Niagara Riverkeeper’s Blue Economy Framework.

These approaches form a cumulative progression—a regenerative strategy includes both environmental performance improvement and health and well-being. Ultimately, though a project team could choose to engage at any of these levels to create buildings that are better than conventional performance, the regenerative approach holds the greatest hope for achieving holistic and long-term benefits for people, their community and the ecosystem.
