As you are well aware, natural light varies from one season to the next, whether we refer to brightness, slant or radiant periods.For instance, does your staff need to add more luminaires, or extra light sources to work well in their environment during shorter days of the year? At home, do you close your curtains against the onset of intense radiance at other times of the year? So, why not adapt artificial lighting to harmonize with Mother Nature’s fluctuations?

Why Adjust Lighting Systems According to Each Season?

To ensure that lighting remains comfortable, welcoming and energy-efficient throughout the year, we must adjust our artificial light to meet the distinctiveness of each season.

As the days of winter are markedly shorter than those of the summer, we should arrange artificial light in such a way that our surroundings are visually comfortable and safe during darker days. And even though the sun goes down, we need to be able to continue our work without any trouble!

Also, we must also consider that light streams through the windows at varying slants; this creates variable lighting needs throughout a space. For instance, a surface that receives no light during the afternoon in summer months might be very brightly illuminated at that same time during the winter. This natural light stream must be toned down in order to avoid excessive glare on the occupants of the space.

How do we go about adjusting our lighting systems from one season to the next?

Adapting Lighting Systems According to the Seasons

Firstly, light sensors are practical devices, as they serve to adjust lighting levels when and where it is needed. As illumination periods fluctuate from one season to the next, these devices send a signal that activates artificial light sources when sunlight is no longer adequate. Thus, artificial light systems operate only when necessary. Light sensors will then illuminate the space of the occupants, yet save energy costs.

By the same token, it might also be strategically sound to install motion sensors that control lighting according to user needs. These systems will turn lights on in a space only when that space is occupied. This way, people can safely circulate throughout a well-lit space, and the administration can benefit from substantial energy savings.

Controlling shade is also a major procedure. Thus, programming the movement of window blinds allows people to remain comfortable in their all year long, no matter when the sun rises or goes down. Moreover, we can regulate the lowering of window shades when the slant of sun rays creates visual discomfort for the occupants on shorter days of the year, for instance, by creating a glare on one’s computer screen.

In addition, when a surface is too brightly lit, control systems may activate the downward slope of shade screens to regulate the brightness level on a given surface while allowing light to penetrate into the rest of the space.

We can therefore take advantage of various light sources (LED, traditional, compact incandescent and fluorescent lighting), dimmers, sensors, control devices, and lighting management systems to achieve the desired effect and compensate for the absence of light during the cold months of winter.

And so, our lighting system should be formulated to adapt to the fluctuations of each season with respect to natural light. Furthermore, lighting should always be subtle and pleasant; it also needs to blend seamlessly with the existing natural light.
