Useful daylight illuminance: a new paradigm for assessing daylight in buildings
Lighting Research and Technology, 2005This paper introduces a new paradigm to assess daylight in buildings called ‘useful daylight illuminance’, or UDI. The UDI paradigm preserves much of the interpretive simplicity of the conventional daylight factor approach. In contrast to daylight factors however, UDI is founded on an annual time-series of absolute values for illuminance predicted ...

Useful daylight illuminances: A replacement for daylight factors
Energy and Buildings, 2006This paper describes the application of a new paradigm, called useful daylight illuminance (UDI), to assess daylight in buildings. The UDI paradigm is designed to aid the interpretation of climate-based analyses of daylight illuminance levels that are founded on hourly meteorological data for a period of a full year.

Below Useful Daylight Illuminance (BUDI): a new useful range measurement parameter
2019 SBFoton International Optics and Photonics Conference (SBFoton IOPC), 2019Light plays an important role in life cycle: light is a normative issue and a common use requirement which helps the perception and apprehension of formal and conceptual aspects. Specifically, in respect to the relationship between user and light, there are intrinsic physiological and psychological issues leading to an understanding between the ...

The first step in evaluating the visual performance and energy efficiency provided by daylight requires an accurate estimation of the amount of daylight entering a building. The actual daylight illuminance of a room is mainly influenced by the luminance levels and patterns of the sky in the direction of view of the window at that time.

The benefits of light shelves over the daylight illuminance in office buildings in Toronto
, 2016 Modern envelope technologies and architectural trends often encourage the adoption of large glazing surfaces. Light shelves are then proposed to reduce glare complaints, while providing better indoor daylight distribution.
