Daylight Factor

In order to calculate the natural illumination that enters to an enclosure or building we occupied to measure the Daylight Factor. The Daylight Factor is the quotient expressed like percentage of the internal illumination in a place with respect to the external illumination without obstructions. The use of this factor is because the natural light presents/displays great fluctuations in its intensity, and the absolute values (lux) are not useful to watch the luminance properties of an architectonic space.

This type of study allows to improve the visual comfort and is useful for corroborating if the minimum levels of natural illumination in a space are obtained.

In order to calculate this factor we use the CIE Overcast Sky model(Commission International de L'Eclairage), that assumes conditions of a cloudy day sky design.


Luminance e Illuminance

By means of the calculation of illuminance (lux) and luminance (cd/m2), we can measure the amount and distribution of lux of each relevant room and consider if possible problems of glare exist.



The solar path analysis uses the latitude where is the building located to throw the exact projection of shadows of that particular place. The advantage is that for being highly visual analysis, allows to understand very quickly how the solar radiation will affect the project in the different days of the year, being given the possibility of identifying spaces whose solar exposure is deficient or excessive. This analysis is also used for the effective design of solar protections.
