This paper describes an experimental study of the effect of atrium roof shape and atrium roof obstructions upon the daylight levels in atrium buildings. The work was carried out using physical models of atrium buildings under real sky conditions, and was divided into three stages. The first part of the study investigated the effect of the atrium roof on available daylight levels in the atrium. The second part examined how obstructions created by structural elements beneath the atrium roof…

Daylight optimization in an office building through atrium improvements
This thesis reviewed the studies that were developed in the field of daylighting in atria and proposed an investigation about the atrium parameters that affected the most the daylight conditions in a building project located in Gothenburg, where it demonstrated that shifting theAtrium characteristic from an enclosed one to a semi-enclosed can double the daylight quantity in the adjacent rooms.
Analysis of atrium's architectural aspects in office buildings under tropical sky conditions
This paper discusses atrium building typology by analysing the architectural aspects of existing atrium buildings. One hundred sixty commercial office buildings in Klang Valley were identified as the
Daylight in Atrium Buildings: A Critical Review
Abstract Using daylight as part of an integrated and controlled lighting strategy is a key component of a sustainable, environmental approach to architectural design. An atrium is potentially a major
Daylight Transmittance of Real Atria Roofs: Assessing a Novel Photoanalysis Technique
This study investigated a novel photoanalysis technique that would reveal transmission information without the need for physical illumination measurements about the transmittance of atrium fenestration systems.
Domesticating Daylight via Atria
Atrium is a semi-open space area that is located within a building. It usually includes a large space that was a distinctive part of ancient Roman dwellings are with providing natural daylight and
Potential Lighting Energy Saving for Top-lit Atrium
Atrium with roof lights is becoming a common feature for commercial buildings in Hong Kong. They bring dynamic lighting to the interior, ie the daylighting level changes from moment to moment and
