Tuning control of buildings glazing's transmittance dependence on the solar radiation wavelength to optimize daylighting and building's energy efficiency

Further advance of glazed, healthy building's energy efficiency and sustainability is inextricable linked to the building's envelopes/facades fundamental physics study related to the dynamic control of sunlight and optimal control of solar heat gains. Relevant mathematical models and algorithms, as well as infrastructure/hardware and software integrated performance prediction and validation are studied. Reviewed is the most recent analytical and experimental research, current state of science and art, as well as some of the on-going R&D at the edge of new breakthroughs of the healthy buildings daylighting dynamic control's performance prediction and validation. It has been shown that, concerning the variability of the solar radiation spectra incident on the building's envelope, and also variability of outdoor and indoor air temperature differences, it is necessary tuning control of glazing's transmittance dependence on the solar radiation wavelength, with an aim to optimize daylighting with the reference to people needs (their health and comfort), and energy (thermal and electrical loads minimization). Finally, presented are elements of an analytical modeling approach, as initial results of study, aimed to reach a challenging research goal - Tuning control of buildings Glazing's transmittance dependence on the solar radiation wavelength to optimize daylighting and building's energy efficiency.
