Evaluating integrated lighting projects - A Procedure to Post-Occupancy Evaluation of Daylight and Electrical Lighting Integrated Projects

This report presents tools for post-occupancy evaluation (POE) to evaluate indoor lighting of commissioned projects (‘case studies’) under a common framework. In this report, POE includes technical environmental assessment (TEA) and observer-based environmental assessment (OBEA). The framework proposed in this report evaluates four key aspects of the case study: 1. Energy use (electrical lighting systems), 2. Visual effects (Indoor lighting environment /photometry) 3. Non-visual effects (circadian potential), and 4. The user (subjective/surveys and observations) The report targets industry professionals, building designers, lighting designers, building managers, researchers and/or owners wishing to evaluate projects where lighting is supplied by a combination of electrical lighting, daylighting systems (e.g., fenestrations) and assisted technologies (e.g., smart sensors). The framework in this report makes available methods and procedures related to the evaluation of integrated lighting performance in residential and non-residential buildings and its impact on users, and it summarises and categorize methods and procedures in an accessible and industry-oriented language. The content of this document is based on methods and procedures used by participating experts in IEA SHC Task 61 for monitoring twenty-five worldwide integrated daylighting and electric lighting case studies. Since integrated lighting projects are different in type and scopes, the methods and procedures included in the framework do not follow a rigid protocol. Practitioners should use the framework to define the scope of POE monitoring in terms of the aims of the project, context, and resources available. The document is thus a toolbox for planning and executing the monitoring of their integrated lighting projects
