Sustainability and Resiliency Journey Beyond LEED

Nathan Zeidler, Longfellow Real Estate
Jeffery Bottomley, Shepley Bulfinch
Jeff Cappelle, NV5

Longfellow's Triangle 54 project is envisioned as a vibrant, world-class science and technology campus for innovative companies in Research Triangle Park, North Carolina. The campus will include a variety of collaborative laboratory, office, and greenhouse facilities as well as unique amenity spaces and lifestyle services.

Triangle 54 will be one of the region's first large-scale life science development properties to consider integrated sustainable and resilient design beyond the typical LEED checklist. The team created project-specific processes, guidelines, and criteria to explore opportunities around carbon, water, people, biodiversity, and climate readiness to achieve the enhanced targets. These methods guided the exploration of new technologies and strategies to streamline the decision-making process and measure success during design.

Join us for a conversation about the lessons learned in analyzing, balancing, and prioritizing the multiple strategies related to central utility plant, microgrid, all-electric system, geothermal, photovoltaic, heat pump, next-gen refrigerant, waste infrastructure, and resiliency all while considering the potential health and wellness impact on occupants through passive strategies and improved environmental biodiversity.
