Promoting the well-being of building occupants is a critical part of ensuring the sustainability of the built environment (in the full sense of Life Cycle Sustainability Analysis, LSCA), pertaining to aspects such as air quality, view outlook, the sense of privacy, thermal comfort, and so on. We present the first prototype version of a new human-centred framework that captures key aspects of the underlying concept structure of qualitative social criteria that are found in popular building certification systems such as the Danish DGNB, WELL Building Standard, LEED, and BREEAM international. We are developing the framework using real human-centred principles taken from literature in psychology, architecture research, DGNB and interviews with architects. We demonstrate a proof-of-concept implementation of the framework on rules about spaciousness via embodied visibility.
