Daylight in adjacent spaces of atrium buildings

Guest author: Pushkin Passey
This dissertation investigates the main characteristics of different atrium geometries and their influence on the daylight condition on the adjacent spaces. The form of the atrium, well reflectances, transmittance of the atrium glass and the size of the windows facing the atrium are important parameters in the daylighting design of the atrium buildings. The level of effectiveness of these parameters is discussed through this dissertation.
The 1-sided, 2-sided, 3-sided and the 4-sided atrium building form are tested on changing the factors mentioned above using Radiance v2.0 Beta as a lighting analysis tool. The results are compared to each other and the 2 shapes which respond best to in terms of fulfilling the requirements for an interior office floor for being uniform with daylight factors of 2-5% (CIBSE 2006) inside the office space are the 3-sided and the 4-sided atrium buildings. These were subjected to the second test investigating the effect of splayed walls as a function of the well index. The results from these tests are analysed to gauge the level of daylight factors in the adjacent spaces and the effect these factors have on the various atrium geometries.
