SolaVeil® working with natural available daylight1. What are the components of sunlight?

SOLAR SPECTRUM

• Ultraviolet Radiation 3%

• Visible Light 44%

• Infrared Radiation (solar heat gain) 53%

2. Performance of technologiesTotal Solar Energy Rejected (TSER)

• Total of all radiation rejected

• What % of each wavelength?

• Maximise Visible radiation (VLT)

• Minimise Infrared

Luminous Efficacy

• VLT / Shading Coefficient

• True measure of Spectral Selectivity

Note: The higher the Luminous Efficacy, the better you are rejecting the IR heat and transmitting visible light.

SolaVeil® - Methods for mitigation of Glare1. Types of Glare• Distracting glare• Disability glare• Discomfort glare• Blinding or Reflecting glare

2. Minimising effects• Remove the source• Reduce the level• Diffuse and flatten• Redirection• Improve contrast ratio• Orientation• Managing people

Note: Different people will have different reactions to glare and exposure to light.
