REQUIREMENTS EXPLAINED
This credit promotes spaces that are designed to enhance the occupant experience through multisensory experiences, connections with nature and natural systems, spatial variability and opportunities for personalization, as well as a broader view of thermal, sound, and lighting design. Though there are multiple options to achieve the credit — and strategies — will (and should) look significantly different between projects. All approaches should aid in catalyzing enjoyment and memorability of the space, in turn, increasing the likelihood of sustained satisfaction and ongoing stewardship of the building. [122]
Option 1. Biophilic Environment
PATH 1. INDOOR BIOPHILIC DESIGN
Biophilic design is based on the ethical imperative to promote human and environmental health and well-being by reconnecting people to nature and to each other within the built environment. Incorporating nature, both directly or indirectly, can offer significant benefits to physical, mental, and social health. [123] Biophilic design can also be a tool to improve how we connect with others to enhance a sense of community. [124] Effective biophilic design considers cultural, geographical, and ecological contexts. Refer to IPp2: Human Impact Assessment findings for relevant contextualization .
Strategies must contribute to an integrated experience and should not exist in an individual or fragmented manner. As such, there is no minimum threshold for the number of required biophilic design strategies. Instead, projects must demonstrate compliance with each of the five principles adapted from The Practice of Biophilic Design. [125]
