8 FINAL SUMMARY 8.2 Discussion 8.2.1 Circadian lighting The CL hypotheses remain untested, but findings from the thesis suggest that it is correct to assume that patients with ED will benefit from the CL to some degree. Patients with seasonality and/or binge symptoms are to a high degree likely to experience some effect of the CL. One of the limitations in the upcoming study is the quality of the installed fixtures. Future measurements will determine if the proposed CL scheme can be applied 1:1 in the installed fixtures in PCBA ED 55. All installed fix- tures are tuneable white and can thus provide scenarios from warm white to cool white, of different span and illuminance levels. In the dining room, the installed fixture has the most limited span (3000-6000K), but Ra >90 and 3-MacAdams. This deprives the research project from tests with more exag- gerated CCTs in the dining section. In other areas of the building, the light levels can differ from 2000-2500K warm white to 6000-7000K cool white. One thing is to specify the exact CCT, CRI, intensity, brightness and re- flection, but the SCN reacts to wavelengths, which means that CL should not solely be based on CCT and illuminance levels. The spectral distribution within the variation of desired wavelengths should be taken equally into ac- count. Professional fixtures show high diversity of spectral distribution and CRI, when attempting to meet 2000K, 3000K or 6500K. One of the delimitations in the design process has been the delay on the finishing of the PCBA ED 55 building. This prevented the option for planned tests and measurements on location, including calculations of daylight in- take and daylight factor, material reflections, tests with hallway mirroring and evaluation of installed fixtures for flicker, glare, circadian stimulus and illuminance levels. 8.2.2 Healing According to vioss.dk (Ingen målbar forbedring i behandling af anorek- si og bulimi - ViOSS - Videnscenter om spiseforstyrrelser og selvskade, no date) more than 80.000 Danish teenagers (16-19y) are at risk of developing an eating disorder. AN is currently the most dangerous disease for young girls to develop, with mortality being 5.35% higher than average, because of severity, treatment obstacles and mortality statistics. (Interview E, 00:21:42) Current treatment of anorexia is personalised and very experimental hence the need for research in new treatment methods. Circadian lighting will not cure AN, but could quite possible have a positive effect on mood, energy levels and symptoms of seasonality and depression. As seasonality and disrupted circadian rhythm are dominant factors in binge behaviour, the circadian lighting, including bright light peaks, will pre- sumably have a higher effect on BN symptoms. The mortality in bulimia patients is much lower than anorexia, hence most bulimia patients will be Master thesis · MSc Lighting Design · Pernille Bech-Larsen · Fall 2017 111PDF Image | Healing with light
