Adequate natural lighting is no longer a purpose to be fulfilled by the designer, is an obligation, and that was well known by the great architect Oscar Niemeyer in many of his works and constructions.
Used natural light indoors not only as a means of saving, of improving the health of the occupant or habitability of the space, but amplified its value to a tool for classifying spaces and forms, as a requirement of expression and meaning.
From what we can consider, the light nature has more importance in the architecture of the than most of us think. There are many secrets that we must discover, and we will explain it to you in detail…
As a prologue, we want to leave an interesting video that emphasizes the most essential points.

The concept of architectural lighting as
The natural lighting in buildings is one of the of the environmental factors that most condition the design architectural and constructive of any building. He lighting project in architecture must of being a resource that must be managed coherent.
The following image perfectly represents the emotions that can transmit architecture light , a work of the famous architect Tadao Ando.
Many architects throughout history have defended natural light as an essential complement in the architecture and interior design, what's more, many use different techniques to strengthen the design style interior taken in a home.
Although there are many architects who work with light in an exceptional way, like the previous naming, Tadao Ando or from the famous Gaudí with his famous phrase… «Architecture is the arrangement of light; the sculpture is the play of light» an example of luminosity palpable we can see it in this video of Casa Batllo. Even the one nicknamed “ the teacher of light ,” architect Henning Larsen .
We want to highlight two points that appear to us important based on two studies that have been carried out with reference to natural light:
Obviously the data showed energy savings, in this case between 16-20% but the novelty was found in the effects it produced on its inhabitants, an estimated increase by 55% the benefits on the non-visual effects of their inhabitants, directly affected the quality of well-being and sleep, improving them in a forceful .
We can also see the article on which are the best windows for home; PVC or aluminum, of interest to recognize the need from within the home.
Specifically, the types of light in architecture that we can find before a building or any construction are those listed below, regardless of the natural lighting systems artificial :
In the following graph we can better understand the types of natural lighting with reference to the types of light on a surface :
Given the weather here comes “temporary stability”, The exterior light level will vary according to solar time, although there can be large fluctuations with cloudy skies due to the sudden transit between clouds and clearings.
It is recommended to limit the fluctuation of the light level to a factor of 1/3 with respect to the average level (for example, 100 < 300 > 1,000 lux) in short periods (Seconds). For keep the natural light stable, it is convenient that the lux predominate diffuse captured from the celestial vault and avoid sunlight designing adequate sun protection.
To clarify the subject a bit and to be able to have a vision globally we have made a scheme – infographic of the points key in ranges and
You have to remember that light and color play an important role and that at the same time go hand in hand with symbiosis, so it is necessary to know the effects of lighting before the color and the effect of the light in a building according to colors .
In this sense, we made an article of interest color in architecture and buildings where an attempt is made explain the different color techniques to use.
This subject involves a series of concepts such as zoning of the lighting , spaces transit before the light and glare that it provokes before the eyes. Given the amount of information that these concepts represent, we have chosen to schematize those in the following image.
Remember that we have an excellent article on lighting with led lamps where we learn everything based on questions about the use of led bulbs.
A project that seems interesting to us is the “ Daylight design variations book ” which has been developed as a set of tools for design natural light openings with interior lighting relevant (windows, skylights, skylights, etc).
The goal is to show a large number of illuminations and their impact on the space of a local, a lighting natural direct. It is a very interesting tool and that provided us with different data of interest on the calculation of light:
In addition to visualization, it also offers us an analysis detail of the chosen hole, a comparison between types of holes and in some cases he reviews photographs of examples.
As a matter of interest, an article dealing with the natural lighting in rooms from HERE.
We are talking about optimizing and enhancing natural resources (sun or natural light, vegetation, wind, etc) that will bring about tangible benefits, sensations, forms and others gains that are adopted at cost relatively low, and should not be forgotten and wasted by the designers.
There are also projects or ideas with light that represents a milestone of change, of creativity natural and concept. We see an example from the article urban creativity, represented in the following image…
We have found a video that perfectly explains from a technical perspective what should we consider when We carried out a natural lighting project, very good!
To understand the scope and be able to "play" with the light of reasoned way we have compiled a series of manuals or guides in light that will help us to better understand of the pairing Natural light – Architecture:
Note: A colleague told us that a simulation of the sun would be missing throughout the day to complement the post, I leave you different free tools of positioning and calculation of the sun that I think are of interest:
On the other hand, another program of best known interest is SketchUp which has a Free version and a Pro version HERE .
