The Center for Health Design has published two good papers:
Wayfinding: Design for Understanding, written by Barbara J. Huelat, explores ways that wayfinding promotes healing, fiscal health and efficiency. In addition, other benefits of a strong wayfinding system are discussed.
Health and Nature: The Influence of Nature on Design of the Environment of Care, written by Jerry Smith, ASLA, LEED AP, reviews the impact of nature on healthcare environments. Smith also discusses the needs of various user groups within these spaces as they relate to nature.
Both are “Best Practices Papers”:
Based on the work the ESC did in 2005 for the “Environment of Care” chapter, individual members are drafting position papers on a variety of topics, including nature and wayfinding. They are available for download at: http://www.healthdesign.org/advocacy/adgroups/escouncil.php.
