European countries are facing healthcare challenges demanding significant improvements in the efficiency and effectiveness of healthcare delivery. Consequently, primary care is being strengthened by developing new facilities. As the design of healthcare facilities inevitably entails a delicate balance between various needs and requirements (functional, spatial, environmental, etc.), alongside economic constraints, it is important to determine which elements should be prioritised in the design of new primary care facilities. For this reason, building performance evaluation (BPE) has become a critical aspect of the design, construction and operation of buildings. BPE tools may provide a rational basis to guide designers and local public authorities in decision-making and in prioritising design objectives to optimise primary care facility design as well as to verify design quality in post-occupancy phases. The aim of this chapter is to analyse validated evaluation tools for healthcare-built environments to provide a comprehensive understanding of their main characteristics (target audience, aspects investigated, application phases, data collection methods, expected outcomes and impacts), thereby developing a guideline framework to streamline the adaptation or development of tools specifically tailored to primary care facilities.
