Overview

Topic status: In progress

Lighting in office buildings is designed according to standards that relate to the conduct of visual tasks, and codes that mandate energy efficiency. There is little or no consideration given to the lighting required to maintain circadian health or to promote quality environments (gloom-free). This project will collect data on light dose and lighting quality recorded for occupants in typical office spaces in order to evaluate the magnitude of the problem in buildings designed for tropical and subtropical regions.  The results will highlight the shortcomings in current lighting standards with regards to daytime circadian stimulation of building occupants and lighting quality.

Research activities

The research activities undertaken include:

  • data collection using personal light meters (Daysimeters) to measure light dose at the eye and digital cameras to measure interior luminances, and survey tools to indicate lighting quality (user response)
  • data analysis of luminance measurements using different predictive models of visual comfort
  • analysis of lighting dose relative to known levels of circadian response.

Expected outcomes

This project will be part of a larger pilot study on the quality and health implications of office lighting in tropical and subtropical regions. This initial project work will inform subsequent data collection and some of the methods developed may be used for future data collection. The results of the broader pilot study (including work form this project) may form the basis for a publication and then future work on the development of lighting standards for health, visual comfort and quality.

Duration of project

This project is of 3 weeks duration. In this time (approximately) 3 days will be spent on preparation for data collection, 8 days will be spent on data collection, and 4 days on analysis of luminance results. Ideally this project would be scheduled so that data collection occurs during times when the subject offices are occupied (i.e. not the December and early January holiday period). The preferred time for offer of this project is late January to February. However, it may be possible to offer the project earlier or later if the need arises.
