Evaluation of daylight performance of classroom spaces in ahmedabad

Abstract

The study uses building energy simulation tools to analyze the conceptual models representative of existing classroom spaces in Ahmedabad, to study the daylight performance. The existing classroom spaces are documented with field studies, analyzed and the best representative classroom spaces are simulated to check the annual performance.Different dynamic and climate-based daylight metrics are evaluated. The data generated from parametric simulation run are analyzed.The approach is to check how the existing typical classroom space perform when tested in terms of various daylight metrics. Following this approach, we can conclude that from the cases that we tested, one of the case performs the best in terms of daylight factor and daylight autonomy but also faces glare issues. Uniform Daylight Index is the metric that will work best in case of classrooms if in future we wish to evaluate the space or design them as it defines a range of illuminances that can be said to constitute useful levels of illumination, however, the upper and lower limit illuminance values are incorporated, while also fixing compliance intervals integrating the concept of target ranges.
