Abstract: The highly glazed building envelope currently dominates building design in the industry. While this provides better views and daylighting, the increased solar radiation can be problematic for occupant thermal comfort. This paper examined the peak operative temperature, peak solar gain, and exceedance hours as quantitative thermal comfort metrics to assist decision-making at the design stage. Using a highly glazed and densely occupied atrium as a case study, an occupant thermal comfort design workflow was developed for engineering practice using long-term building simulations. The integrated design approach in building envelope and mechanical system strategies helped achieve a design solution which reduced the number of exceedance hours in dissatisfied zones by 70-95%.
