Lighting How much blue light is needed? Research indicated 40 lux for 80 minutes Since the shift workers were already awake We designed the Circadian Lighting to provide 80 lux to the eye Time suggested is 20 minutes All images and copyright belong to original owner and are reproduced here for the purposes of training and education only Original work by Rick Morrison
Conclusion. • Light has been shown to be vital or primary to human wellbeing. • Natural circadian rhythm response to short wavelength light can be used in design to successfully create a space able to provide the stimulus described by the various publications of circadian research. • Each Circadian Space in the Hospital Project is designed to provide an ambient light level onto the observer’s eye of approximately 80 lx, which is comfortably above the minimums described. (1, 3, 4) • The Circadian Spaces described are being built for the Queensland Children’s Hospital Project, which opens for business in 2014. • Once the rooms are in use, the proposed survey (refer to appendix A) will be instigated, and the survey results collected on a weekly basis. • Every six months the survey results will be collated into data and the design will be reviewed accordingly. It is planned to publish subsequent follow-up papers with the progressing results.
