Optimum lighting in the work area

Optimum lighting is essential for the effective development of the workspace. Light is one of the most important forms of energy that human beings can use, since it is an essential element for the ability to observe, and necessary to appreciate the shapes, color and perspective of the objects that surround it.
In the workplace, where people spend most of the day, lighting is a fundamental factor because it not only influences the well-being and health of staff, but also has an impact on employee motivation and performance, given the that if the lighting is poor it can cause visual fatigue, neck pain and nausea, while if it is very bright it can cause headaches, stress and vision problems.
Adequate lighting in the work area promotes:
  • Increased job performance.
  • Greater concentration and precision at work.
  • Reduced risk of accidents and health problems.
  • A more comfortable and clean workplace, which results in a more active and joyful environment.

Por lo anteriormente descrito, las instalaciones requieren de un sistema de iluminación que no sólo satisfaga las necesidades visuales del usuario, sino que también le brinde ambientes saludables, seguros y confortables, minimizando el impacto ambiental (y la consecuente huella de carbono) mediante un uso eficiente de los recursos energéticos empleados.

Diseño para obtener Iluminación Óptima en el área de Trabajo

Al diseñar un sistema de alumbrado óptimo, la iluminancia requerida del lugar dependerá del tipo de tareas y del medio ambiente en el que se realice el trabajo. Por ejemplo, si el trabajo es detallado, como la inspección, montaje de piezas pequeñas o dibujo técnico, se necesita una gran cantidad de luz. Por el contrario en obras gruesas, como carga y descarga de materiales, manejo de materiales o envasado, requiere menor cantidad luz.

The considerations that must be taken for the lighting design of any workplace are: the dimensions of the place, the colors and textures of the walls, floor and ceiling, windows, door, objects in the place that could cause shadow to the user, the number of day and night hours of work and the balance between artificial and natural light.

It can be said that a lighting system is adequate when it complies with the illuminance levels recommended by the Occupational Safety Standard on the matter, which in Venezuela is governed by COVENIN 2249-93 – “Illuminance in tasks and work areas” , but also that in the work area there is a glare index (UGR) less than 30, since higher values ​​cause the sensation of discomfort in the eyes.Finally, it must be verified that the proposed solution does not lead to excessive energy consumption. This is achieved by accounting for the Energy Efficiency Value of the Installation (VEEI), which accounts for the lighting produced vs. energy consumption. The designer must guarantee that this is less than what is established by the Technical Building Code (CTE), depending on the purpose of the lighting in the premises.

Office Simulation in DIALUX EVO 3

In the RGA office of 20 m 2 , a lighting study was carried out through the following steps:

  • Survey of illuminance levels present in the premises, using a Luxmeter at different points of the premises and on work surfaces.
  • Validation of what is reported by the DIALUX EVO 3 software with the measurement on site.
  • Development of a lighting system optimization proposal based on the requirements of the COVENIN 2249-93 Standard.

The improvement proposal complied with the lighting levels required by the standard for this work area (300 lux), as well as with a UGR on the work surface below 19. Combining these variables was complicated, since Despite the fact that the lighting levels were met, the UGR index was above the maximum parameters required, especially on surfaces close to the wall, since being white presents a high degree of reflection. As a solution, the levels of general illuminance were decreased and this was complemented with localized illuminance in those places with UGR problems.

Finally, the VEEI was another important parameter that was taken into account for RGA’s lighting proposal, achieving a 65% improvement in the Energy Efficiency of the Facility.

In conclusion, good lighting in the workplace is essential for the well-being of employees and collaborators, since it is an important factor in increasing productivity and work performance. For this, a lighting design is required which complies with the illuminance levels of the place, the activity carried out, the UGR index, and the VEEI established in the standard and auxiliary codes, and thus provide security and visual comfort to users, without this implying increases in the carbon footprint of the company’s operation and its environmental impact.
