Abstract
Electricity consumption is the highest energy drainer when it comes to artificial lighting used in offices even though maximum office-hour coincides during the day time. Although few simple design inclusions in the initial phase of designing can reduce electricity consumption as well as add bonus effects such as physiological and psychological improvement through use of daylight, it is still neglected due to lack of awareness and negligence. Even if not included in the design phase, simple design modifications might change the scenario altogether. Proper daylight use can be of economic and health benefit. The author aimed to evaluate on the use of solar panel louvers in existing buildings to avoid glare from excessive daylight and its optimum utilization in open plan offices in context of Dhaka. To achieve this, it required field survey, questionnaire survey, user satisfaction interviews, background study and software simulation. Daylight simulation has been performed by producing the virtual urban environment based on the survey of a true site urban office building located in Dhaka, Bangladesh. Through software simulation Climate based daylight modelling has been done using Ecotect, RADIANCE- based DAYSIM. It was made possible to assess possible solar panel louver options with varying angles, that would provide optimum Daylight use and help reduce unwanted glare as a more sustainable option. ECOTECT is used as a modelling interface to launch the DAYSIM program. For a sustainable building design, general methodology and information provided in this paper will accompany in future scope of research and implementation.
