Aspectos a considerar en el manejo de la luz natural

• Cambio:

“The most obvious and certainly the most important aspect of daylighting is its capacity for change. Change is at the heart of daylighting, the human body has a capacity for adaptation, particularly in vision, and the need to exercise this response.

First there is the natural change from day to night, from first light until dark and the need for artificial sources to take over when daylight fades.
Then there are the changes associated with changes of the weather; from bright sunny days to dark and cloudy or rainy days, there is little doubt that the human spirit soars when rising in the morning on a bright day, an experience which is less likely to happen when it is dark and gloomy outside. Closely associated with changes in the weather are those of the changes of season, from the winter snows to summer sunlight; each season will have its own character.”

• Modelado:

“Modelling of a shape derives from its physical form, whether round, square or otherwise, coupled with the way in which light plays on its surfaces. This is referred to as its modelling and when this derives from daylight or sunlight, giving light from a single direction, this provides a form which is perceived by the eye as having meaning, unambiguous

The most usual daylight modelling is that derived from vertical windows at the side of a room, giving light from a single direction; this may be helped by windows from an adjacent wall which adds to the modelling; as the light will still be from the same overall direction, but adding to the total modelling.

Example of this is the original David statue by Michelangelo seen in its setting in the art gallery in Florence, lit from daylight above, where the form changes in time as
the day goes by. A more modern example of the use of overhead daylight to light a
statue is the Charioteer in Delphi”

• Orientación:

“The importance of orientation in a building must be considered at the outset, when the architect is planning the location of the building on the site, the aim being to ensure the maximum availability of useful natural light and sunlight to the interior.”

• Efecto de la luz solar:

“Sunlight adds to the overall level of light when it is available, and adds to those other environmental factors such as variety and change, modelling and the creation of delight.

There is a different level of experience when getting up in the morning to a sunlit world, as experienced from the interior of a building, and it is important that an element of sunlight is available for some part of the day.

There is of course the obverse side associated with heat gain and glare,
depending upon the orientation of the glazing, and whether people working in a building are confined to a fixed position.

The effects of direct sunlight can be a disadvantage. Some control may be required in certain circumstances at certain times of year, and as far as heat gain is concerned this is best done beyond the window, and is of a sufficiently”

• Color

“Whilst the colour of daylight will vary from morning to evening, and with changes in the sky and weather patterns; it is always regarded as the reference by which colour is judged . . . daylight is regarded as ‘real colour.’”
