Recognizing the value of open-source research databases in advancing the art and science of HVAC, in 2014 the ASHRAE Global Thermal Comfort Database II project was launched under the leadership of University of California at Berkeley’s Center for the Built Environment and The University of Sydney’s Indoor Environmental Quality (IEQ) Laboratory. The ASHRAE Global Thermal Comfort Database II (as it is known) is intended to support diverse inquiries about thermal comfort in field settings. The...

Using the luminance adjustment procedure, we evaluated four discomfort sensation on a Hopkinson-like glare scale: (a), (b), (c) and (d), respectively. Two methodological factors that were beleived to influence the luminance adjustment procedure were investigated. One was the stimulus range bias effect. This describes how the influence of the available range of a variable stimulus (i.e., glare source luminances) influence the setting made to a subjective sensation (i.e., "just uncomfortable" glare). 42 test participants were...
