Let There Be Light: Key Indicators To Describe And Design Visual Comfort

Natural lighting -and how it should be complemented with artificial lighting- is an essential factor to consider for the visual comfort of interior spaces. Important changes in light levels or sharp contrast can cause stress and fatigue as the human eye is permanently adapting to light levels. When designing a new project, take full advantage of the orientation of the site and provide users with the best natural light possible through the correct design of openings. To evaluate the quantity of light, the distribution of light in space and the Illuminance should be measured at specific and relevant points for the functions that will be carried out in the room. The WFR value must be multiplied by the value of the Visible Light Transmission of the chosen glass, explained below, to ensure that the design moves within the thresholds that ensure certain effective levels of visual comfort. Decide the amount of light that must pass through the glass: Visible Light Transmission. As described above, the relationship between the openings and the space must be complemented with the Visible Light Transmission, which corresponds to the amount of visible light that passes through the glass.
