About the Event

Expected Course outcome

The course is designed to aid students/ professionals in the building field to be able to design a building/ space to be well daylit. As daylight is an integral part of the physical and mental wellbeing in one’s life, an Architect must incorporate daylight designing in a building, and the engineer understands the intent behind the design. At the end of the course, participants will have good knowledge of daylighting and its fundamental qualification through daylight performance metrics using Lightstanza.
