The donation of the Nuthatch Hollow site to Binghamton University added another beautiful, natural environment to the University campus. But more importantly, it added a diverse ecosystem within which to do research and teaching in environmental sciences. The University has a deep commitment to advancing our understanding of how humans can be better stewards of our communities and the environment. During early discussions about how best to utilize this site, the idea of a Living Building Challenge (LBC) certified facility quickly took hold. The LBC embodies many aspects of the mission and aspirations of the University as a whole and provides many opportunities for faculty and student involvement in the design of this new facility. This post provides an overview of the LBC while later posts will dive more deeply into specific imperatives within the LBC.

At its core the Living Building Challenge is the most aspirational building standard in use today. It works to explore what the future of the built environment should look like in a world where humans not only live within the limits of the carrying capacity of our planet, but actually enrich the environment and the communities within which they live. As such, the standard touches on a broad range of sustainability concepts from environmental to economic to social.

The requirements of the LBC are structured around the metaphor of a flower with 20 Imperatives organized within 7 Petals. In order to receive certification, the Imperatives must all be achieved and proven after one year of occupancy.

The following is a quick overview of the Petals:

  • Place: Construct only on previously developed land and avoid sensitive areas; incorporate urban agriculture; offset developed land with permanent habitat offsite; encourage human powered movement.
  • Water: Use only the water that falls on site and process waste water on site, both in sync with the site’s hydrologic cycle.
  • Energy: Create 105% of energy needed on-site through renewable energy; no on-site combustion (no fossil fuels); battery storage to provide resilience.
  • Health and Happiness: Provide operable windows in all occupied spaces; excellent indoor air quality; incorporate biophilia into design.
  • Materials: Avoid products that contain chemicals and materials from an extensive “red list”; quantify, reduce and offset the embodied carbon in the building; use more regional materials; reduce or eliminate waste.
  • Equity: Provide human-scaled spaces accessible to people of all abilities.
  • Beauty: Provide a beautiful building and environment to enhance well-being.
