New Daylighting Metrics

Abstract

Traditional daylighting metrics are gradually replaced by metrics based on absolute photometric parameters that are applied over the whole year. This process is at the stage of implementation in the design practice. The move to more realistic measures of daylighting is associated with a number of theoretical and practical problems. This article brings information about family of newly climate-based daylighting metrics that were developed in the world recently. The article also highlights some of the problematic aspects of climate-based daylighting metrics.
