Optimizing indoor illumination quality and energy efficiency using a spectrally tunable lighting system to augment natural daylight

open access: yesOptics Express, 2015
This article demonstrates the benefits of complementing a daylight-lit environment with a spectrally tunable illumination system. The spectral components of daylight present in the room are measured by a low-cost miniature spectrophotometer and processed through a number of optimization algorithms, carefully trading color fidelity for energy efficiency.

Real-world validation of climate-based daylight metrics: mission impossible? [PDF]

open access: yes, 2016
One of the criticisms of metrics founded on climate-based daylight modelling (CBDM) is that they are unverifiable in practice. This criticism received some attention following the decision in 2013 by the Education Funding Agency to make CBDM and the ...
