In the last decade there was a growing attention for the built environment in relation to health. A growing body of research in evidence-based design (EBD) demonstrates that elements of the physical environment do correlate with health-related outcomes.

The framework of this thesis is The International Classification of Functioning, Disability and Health (ICF) of the World Health Organization. The ICF model is adapted to a framework for health outcomes based on theories in the field of Corporate Real Estate Management. Several studies of Corporate Real Estate Management show how corporate real estate directly and indirectly adds value to the core business of the organizations. This PhD-project focuses on Corporate Real Estate aspects which are aligned with the concepts around healthy and sustainable environments. The purpose of this thesis is to provide evidence for indoor environmental aspects include light, acoustic and thermal comfort that influence work-perception of care professionals and/or client health outcomes to help CREM create added value. The outcomes of the PhD-project will underpin an integrate knowledge for building engineers, installers, consultants, facility managers, and the board of healthcare facilities through generating evidence of sustainable environments for healthcare facilities.
