PROJECT OBJECTIVE
This project proposes to bridge the gaps between lighting in today’s buildings and lighting in future buildings through improved design guidelines and processes, installation and commissioning practices, and sensor and control algorithms. Specifically, the project team will focus on developing common metrics for daylighting and lighting.
The results of this project are intended to advance alignment between the implementation of building lighting systems and the needs of future buildings and building occupants. After an initial planning phase, the project will proceed through two main phases of work: simulation studies and validation research. The planned simulation work for this project extends the prior knowledge in several important ways:
- Spectral modeling: This project will simulate the spectral interactions of light sources (using previously published spectral data for daylight and electric light sources), building surfaces and objects across a full range of narrow spectral bands (e.g., 5 nm widths), using new tools such as the Adaptive Lighting for Alertness (ALFA) software.
- Calculating metrics for occupant needs: This project will address metrics related to both visual and non-visual impacts of light on building occupants.
The goals of this project are to transform the way that daylighting and electric lighting systems are designed and implemented in buildings, and to inform the development of next-generation connected lighting technologies so that they are optimized for future buildings. The final outputs of this project will be new lighting system design and installation guidelines, and technology recommendations based on engineering research combining detailed simulation studies with laboratory and field validation research.
PROJECT IMPACT
The result of accomplishing this goal is to reduce lighting energy use in buildings, with energy savings estimated at over 210 TBtu relative to a 2030 baseline condition, and to provide light of the desired spectrum, amount, distribution, timing, and duration for the overall health, comfort, and satisfaction of building occupants. The proposed project will provide important design guides and recommendations for technology developers, building designers, and installers for consideration by industry standards-setting committees.
