Effect of VLT in Daylighting

What is VLT of glass? VLT stands for Visible light transmission. It is the amount of visible light that can pass through an optical or sun lens. It can also be called visible light transmittance or VLT%. This is measured as a percentage which indicates the darkness of a lens within a sunglasses frame. The […]

Daylight is merely the visible part of the radiant energy that enters through windows. Furthermore, the bulk of the daylight energy that enters a space is converted into thermal energy after just a few reflections. Many office buildings in moderate climates now have air conditioning largely due to the high internal gains. In warmer climates […]

Importance of Daylight simulation in Green building Certification

What is Daylight Simulation?A computer-based calculation of the amount of daylight available inside or outside of a building under one or several sky conditions. Simulation outputs may be discrete numbers (illuminances and luminances) under selected sensor points within a scene or visualizations of a scene. Daylight is merely the visible part of the radiant energy […]
