Beyond the science and art of the healthy buildings daylighting dynamic control's performance prediction and validation

摘要

Further advance of the healthy building's energy efficiency and sustainability is inextricably linked to the building's envelopes/facades physics study, particularly fundamentals of the dynamic control of sunlight and optimal control of solar heat gains. Based on the improved understanding of mechanism which physically control specific materials intensity, e.g. absorption, reflection and transmission of solar radiation, are to be improved strategies to dynamically control separation of the daylight admittance from the solar heat gains. Relevant dynamic control mathematical models and algorithms, as well as infrastructure/hardware and software integrated performance prediction and validation are to be further developed. This paper reviews the most recent research and development results, the current state of the science and art, as well as some of the ongoing R&D at the edge of new breakthroughs of the healthy buildings daylighting dynamic control's performance prediction and validation. Finally defined is a challenging future research goal-tuning control of buildings glazing's transmittance dependence on the solar radiation wavelength to optimize daylighting and building's energy efficiency.
