Indian Institute of Technology Delhi

Energy Efficiency Acoustics and Daylighting in Building

Indian Institute of Technology Delhi and NPTEL via Swayam

This course may be unavailable.


The objectives of this course is to expose the students to the concepts functional design of building for thermal aspects and energy efficiency; especially in tropical climates i.e. in Indian context. Further objective is to make the student capable of performing fenestration design for natural ventilation and daylighting & design of space for externaland internal noise control.
