In this session, we will use case study examples to examine how daylighting performance can be integrated with thermal performance to achieve an optimized and balanced building design. Several simulation tools (DesignBuilder, Ecotect/Radiance, DIVA-for-Rhino) and sample projects will be presented to demonstrate a holistic design process that can be used to achieve this goal.

Title: Integrated Daylight and Thermal Analysis for optimized building envelopes - Early Stage Design Tools
Description: A building’s energy use and user comfort are directly linked to two critical parameters of its envelope design: enhanced thermal performance and daylight harvesting capability. A good foundation for optimum envelope design requires integrated daylight and thermal analysis, so that the many diverse building design components efficiently function together. Early in the design process, components such envelope, site-orientation and shading systems are often analyzed independently from a daylighting perspective without accounting for their thermal performance. This may lead to occupant discomfort (glare), lack of daylight (closed blinds), wasted construction costs, and poor energy performance. What is lacking is a process that integrates daylighting and electric lighting simulation data with whole-building energy analysis to achieve a truly integrated high-performance design.
