With ever higher and more precise building performance requirements, justifying the choice of systems and materials used becomes a real challenge. Starting from the declarative values announced by manufacturers, architectural integration and then implementation can lead to results that are quite far from the objectives initially targeted.
We choose to put our systems to the test and study in order to offer specifiers, design offices and companies an estimate of their real impact on the luminosity of buildings.
We are associated with ArchiWIZARD, 3D modeling software based on ray tracing technology, and we provide the e-catalog of our translucent systems.
The Controlite® is a unique product perfectly in line with the RT2012. Equipped with internal and external light sensors, it automatically directs its integrated sunshade slats so as to maintain a constant level of lighting inside the building.
Can be used as roofs and facades, its capacity for dynamic regulation of solar gain contributes effectively to the energy performance of buildings.
We have developed a dynamic model compatible with ArchiWIZARD.
Example of results of a study where the performance of 3DLITE is scrutinized through a simulation study of light inputs. They are based on RT2012 weather data from the Trappes station (78).
Type : Gymnase
Localisation : 78
usable floor area : 1796 m²
studied surface : le terrain de jeu de 800 m²
The study carried out assesses the impact of the 3DLITE rooftop system on the brightness available at the playground level. ArchiWIZARD software simulates direct and diffused light flows throughout the year. Illuminance maps show the fluxes measured in March, June and October, at three times of the day: morning, noon and late afternoon.

The curve illustrates those flows where direct light, which can be the cause of glare, is largely blocked by the opaque cells of the 3DLITE, in favor of a diffused light which spreads through the cells translucent 3DLITE, propagating a homogeneous light.
Thus, the light supply remains sufficient and regulated throughout the day without dazzling the players.
Brightness difference, between the incidences of the beginning and the end of the day and the maximum incidences of midday, is well controlled . For example, for our day of June 14, we observed a difference in flow, on the playing field between the center and the less exposed areas, of 400 to 700 lux.
We find that the light flux measured during the 3 periods oscillate between 437 lux (darkest period, in March at 4:00 p.m.) and 2733 lux (brightest period, in June at 12:00) or a difference of 2296 lux between these two extremes.
This ArchiWIZARD study demonstrates the effectiveness of 3DLITE in regulating light on a playing surface and justifies the choice of a system that would meet the natural light needs of this type of sports building.
