This talk was co-presented by Daniel Glaser and Sydney Nelson.

With the increasing demand for, and execution of green-buildings through standards such as LEED, Architecture 2030, Net Zero Energy Building, and the WELL Building Standard, the need for proper integration of energy and daylighting tools is of critical importance. Unfortunately, many current energy and lighting tools in the marketplace are interoperable, and as a result, over-represent or misrepresent the effects of daylighting. Energy tools not only limit the geometric expressiveness of a lighting tool– stripping out mullions, wall thicknesses, and other essential details from daylight models, but also do not model occupant behavior or provide detailed lighting calculations. 

For the presentation, Daniel Glaser and Sydney Nelson addressed how to use daylight modeling tools with a focus on precision through annual metrics like Spatial Daylight Autonomy and Annual Sunlight Exposure, as well as the importance of blinds operation, daylight glare probability, and other details specific to daylight. Then they led an open discussion on interoperability among contemporary tools. Streamlining and sharing of daylighting analysis into energy tools is a missing link that has prevented energy modeling and simulation from providing both a more holistic and realistic understanding of energy use in building. By focusing on electric lighting and daylighting separately, designers, engineers, and architects are able to achieve true accuracy and all-encompassing analysis for vastly improved individual and collaborative outcomes.
