High and low light transmittance of solar glass

4 FAQs about [High and low light transmittance of solar glass]

Is high transmittance glass better than low energy glass?

The results showed that high transmittance glass transmitted approximately 4.5% of the outside natural UV-B light, while it was completely blocked by the 3-layered low energy glass. The study found statistically significant differences in self-reported health.

What is visible light transmittance (VLT)?

Visible light transmittance (VLT) is a percentage of the visible portion of the solar energy spectrum coming through the glass. It is expressed as a figure between 0 (no light) and 100 (all light). This value measures the ability of the glass to transmit light and facilitate daylighting.

Do glass types affect Daylight transmittance?

Results: The results showed that the glass types differed significantly in measured daylight transmittance. The two-layered high transmittance glass transmitted 15% more visual light (380–750 nm) and 20% more light in the spectral range (460–480 nm), stimulating ipRGCs and circadian rhythm, when compared to three-layered low energy glass.

Are ''high-transmittance low-emissivity'' windows a problem?

The pursuit of ‘high-transmittance, low-emissivity’ windows encounter two primary challenges. First, conventional glazing materials with high transmittance, such as soda-lime glass, inherently have high thermal emittance (∼0.84), which leads to significant energy losses .
