2. 1. Experimental study of an intermittent ventilation system in high occupancy spaces

   Author : Alan Kabanshi; Patrik Sörqvist; Hans Wigö; Robert Ljung; Hazim Awbi; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. READ MORE

4. 2. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design

   Author : Anahita Davoodi; Myriam Aries; Peter Johansson; Thorbjörn Laike; John Mardaljevic; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lighting quality; visual comfort; lighting simulation; evidence-based design; field study; post-occupancy evaluation; Ljuskvalitet; visuell komfort; ljussimulering; evidensbaserad design; fältstudie; brukarutvärderingar;

   Abstract : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.
