Despite several existing wavelength-dependent models to predict spectral-effectiveness of light, none includes user behavior into this equation for maximum exposure. These methods only partially can predict the health potentials of the lighting with assumption of static building occupants on fixed pre-defined points. The dynamic human behavior to light exposure has been addressed in fewer studies where photometric measurements and eye-tracking methods have been coupled for observation on gaze responses to light.
Using the principles of the aforementioned method, here we propose a proof of concept pilot study to tackle the shortcomings of the existing healthy lighting solutions. The proposed pilot study will run in a representative environment. The selected case study is undergoing an intervention for better daylight access. Three months of experimentation will be performed where performance and user assessments methods developed at DTU will be coupled with orientation tracking using cutting-edge technologies. All environmental parameters will be
monitored using advanced sensor technologies. Combining methods and techniques, we propose two work packages: Firstly, we will focus on the performance rating for different interior layouts. Secondly, we will do an exposure characterization where the dwell and track data will be used to define exposure ranges to spectral effectiveness of the space. The results will be communicated through student work, publication and two seminars.
