Design strategies to alleviate negative psychological and physiological effects in underground space.

This paper summarizes negative psychological and physiological effects associated with underground buildings, identifies design strategies to alleviate them, and evaluates the effectiveness of some of these design techniques. The focus of the paper is on deep underground space with limited connection to the surface environment. A case study of design strategies used in deep underground office space is presented, and two proposed projects that further illustrate design techniques for deep milled space underground environments are described.
