The programs are compared based on their ability to calculate the daylight factor on a working plane and the depth of daylight penetration.
Danish Building Research Institute, Aalborg University Energy and Environment September 2013 Søren Aggerholm Research Director 4ħ Main findings This report investigates the performance and accuracy of nine different simulation programs commonly used by professionals and researchers in the field of architecture and engineering. A special thanks to the speakers Nanet Krogsbæk Mathiasen from the School of Architecture Copenhagen, Francesco Anselmo from ARUP London, Glenn Elmbæk from Arkitema, Steffen Petersen from Alectia/AU-ASE and Mette Hvass from COWI. The participants came from ARUP London, the School of Architecture in Copenhagen, Rambøll, Grontmij, Esbensen, DTU, Niras, Alectia, Danske Ark, CCO Architects, Schmidt Hammer Lassen Architects, Aarhus University, VHR Holding and the Danish Centre for Light. The core group would like to thank the participants in the two workshops held in relation to the project. The report describes an investigation of the ability of nine simulation programs to calculate the daylight factor on a working plane in five typical rooms.

Furthermore the aim was to provide knowledge of how to build up the 3D models that were to be daylightanalysed. The aim of the project was to obtain a better understanding of what daylight calculations show and also to gain knowledge of how the different daylight simulation programs perform compared with each other. The following persons formed the core group: Kjeld Johnsen, SBi Aalborg University Anne Iversen, SBi Aalborg University Mette Hvass, COWI Michael Jørgensen, COWI Nicolas Roy, VELUX Jens Christoffersen, VELUX Glenn Elmbæk, Arkitema Werner Osterhaus, Aarhus University Steffen Petersen, Aarhus University/Alectia Christian Anker Hviid, DTU/Alectia The COWI foundation and VELUX supported the project.
The project focused on daylight calculations in practice and was conducted by researchers from SBi, Aarhus University (AU-ASE) and the Technical University of Denmark (DTU) as well as consultants and architects from COWI, VELUX, Alectia and Arkitema. 9 Workshop Content Participants The work of the core group Daylight demands Danish Building Regulations Danish Working Environment Authority Definition of daylight factor Methods for analysing the daylight factor Calculation methods Accuracy of daylight calculation Split flux formula Radiosity Ray tracing Photon mapping Sky types The model Surface properties User expertise Description of simulation programs Radiance Daysim Desktop Radiance IESve DIALux Relux Ecotect VELUX Daylight Visualizer LightCalc Graphical presentation of the results Simulations and analysis Room types Simulation parameters Guidance to result sheet simulations ROOM 1 SIMPEL ROOM Simulation sheet ROOM 1 - SIMPEL ROOM Analysis sheet ROOM 2 DEEP ROOM Simulation sheet ROOM 2 DEEP ROOM Analysis sheet ROOM 3 ROOM WITH OBSTRUCTIONS Simulation sheet ROOM 3 ROOM WITH OBSTRUCTION Analysis sheet ROOM 4 ROOM WITH LIGHT SHELF Simulation sheet ROOM 4 ROOM WITH LIGHT SHELF Analysis sheet ROOM 5 ROOM WITH BORROWED LIGHT Simulation sheet ROOM 5 ROOM WITH BORROWED LIGHT Analysis sheet Assessment of the nine daylight simulation programs ReferencesĦ Preface This report presents the results of a project initiated by COWI and the Danish Building Research institute (SBi), Aalborg University.
