Final results

An overview of results and overall business and possibly societal purposes of the project. 

Our sprouting project, Response-driven Environments for Appropriate Lighting (REAL) is finalized with clear steps forward.

The end results, in collaboration with VELUX A/S, Henning Larsen Architect, MOE, and LeapCraft, are a simulation framework and disseminations in form of a magazine article and a journal article submission. The project also diverged into four student projects involving six enthusiastic DTU students who were set out to investigate the effects of lighting on human performance through user-assessment experimentation at DTU library.

Our project sought to develop a pathway towards healthy indoor environments by creating frameworks that relate human objective orientation-reflexes to daylight towards informative outputs. A pre-validated simulation workflow was developed for digitalization of the building based on human responses and aligned with Build 4.0 goals. More importantly, the developed workflow coupled with occupancy sensors can give real-time information to the occupants regarding their light environment and achievable productivity levels. The effect of such solutions for the building occupant and owner are beyond the immediate needs of the society and towards continuous performing outcomes.

In the first part of our project, we created an experimentation protocol to investigate effects of (day)lighting on occupant performance. We monitored our randomly selected participants using questionnaires and occupancy sensors. We also monitored indoor environmental parameters using different measurement tools. The experimentation phase resulted in a questionnaire with three major parts beside demographics of the participants: Satisfaction, Mood, and Performance to be used in relation with indoor environmental parameters. We did a thorough literature review on research studies relating light and human performance in educational buildings where we depicted the need for standard protocols and frameworks for a refined understanding of light exposure on performance.

Based on the data and knowledge gathered in the first part we developed a simulation framework using visual scripting methods which uses state-of-the-art knowledge in the field of daylighting. The simulation workflow includes a preliminary mathematical model for estimation of performance rates as result of light exposure at any point in space.

We have gathered all the details related to the experimentation and the developed tool in a final report.
