LiQuID is an analytical tool for evaluating a comprehensive set of lighting data to
account for the complex nature of daylight. The program is designed to generalize large
collections of lighting data by performing automatic classification, lighting quality
analysis, and a summary component. Automatic classification is a data-driven method for
identifying and organizing sets of data, based on similarities in light intensity and
distribution. Lighting quality analyses are based on the normative lighting characteristics
defined in industry standard handbooks (e.g.(Illuminating Engineering Society et al.
2000; Benya et al. 2001)). These sources contain guidelines on evaluating architectural
models for factors like direct glare and light distribution. A summary module integrates
with a user interface for a building designer to review.
