Daylight modeling unlocked the optimal balance of light availability, solar glare, thermal performance, and access to views for a state-of-the-art education facility.
A highly energy-efficient envelope was a key element of the brief for this all-electric, carbon-neutral, interdisciplinary education hub that is targeting LEED Platinum certification. KPF performed detailed in-house daylight analysis to demonstrate that simply minimizing the size of windows to save energy would have the unintentional side effect of cutting back on daylight access, especially in the center of the building, negatively impacting occupant well-being during Detroit’s long winters.
By modeling alternative façade solutions using a climate-based modeling engine that examines the hourly impact of solar and sky conditions, KPF iteratively tested each design option against potential energy savings. A parametric design space of varying glazing ratios and properties was evaluated for each individual educational space, quantifying hours of useful daylight, risk of solar glare, and need for interior shades. This empirical approach yielded an optimal façade solution that strikes a balance between interior daylight, visual comfort, and energy efficiency, integrating the priorities of all project stakeholders.
