Abstract

This research explores the integration of nano-ceramic window films as a passive architectural strategy to improve both energy performance and occupant biological well-being in commercial buildings. The biological objective centers on enhancing health, comfort, and physiological stability by regulating thermal, optical, and radiative indoor conditions. Simulations on a three-story, 2,000 m² building demonstrated that high-performance films reduced indoor temperatures by up to 3.5°C, lowering thermal stress and core body heat load. Ultraviolet (UV) transmission was curtailed to as low as 1%, significantly decreasing skin damage doses below 0.2 MED/day. Select films maintained optimal Equivalent Melanopic Lux (EML) levels (up to 7,500 lux), supporting circadian regulation and cognitive function. Cognitive performance was further enhanced through improved thermal comfort and daylight modulation. These outcomes affirm the potential of nano-ceramic glazing to deliver a biologically informed, energy-efficient solution, aligning architectural design with thermoregulatory, dermatological, and neurobehavioral health requirements.
