Abstract
Transmitted external daylight through semitransparent type building integrated photovoltaic (BIPV) windows can alter the visible daylight spectrum and render different colors, which can have an imp...
Highlights
For a building, lowering energy consumption gets a higher priority, while the most neglected yet often pivotal requirement is visual comfort for dwellers.[1]
This predicts that correlated color temperature (CCT) and color rendering index (CRI) are not single transmittance dependent values but give spectral dependent parameters, and these include D65 and spectral power distribution of natural daylight
Ambient exposed Dye-sensitized solar cells (DSSCs) glazing was investigated for color comfort analysis 2 years after its fabrication
Summary
For a building, lowering energy consumption gets a higher priority, while the most neglected yet often pivotal requirement is visual comfort for dwellers.[1]. To evaluate the occupant comfort due to the color property of transmitted solar light, color properties include a suitable CRI > 80 whereas close to 100 is required for higher performance of glazing followed by the CCT variation in between 3500 and 7500 K.5. DSSC glazing higher than 50% transparent is a potential glazing system for new or retrofit window, as they possess allowable CRI and CCT as reported by Ghosh et al (2018).[17] the suitability of semitransparent DSSCs for fenestration integration was investigated in terms of clearness index and glazing transmission correlation.[10] In this work, less explored color properties of transmitted solar light such as CRI and CCT were analyzed for DSSC glazing.
