Achieving energy efficiency is one of the objectives that we, as responsible citizens and society, must incorporate into our agenda if we want to enjoy sustainable well-being. There are tools within our reach, such as motion and presence detectors, which will allow us to easily reduce electrical energy consumption and provide our environments with the necessary comfort to adequately develop the activities for which they are designed.

According to the European Commission, 40% of total energy consumption in the EU corresponds to expenditure by residential buildings and the tertiary sector (or service sector). This is a very high percentage, so the potential energy savings to be found in these sectors are also very large. These savings can be realised through two types of actions:

  • Improvement of the electrical installation and materials used.
  • Installation of electrical devices that reduce consumption or provide the necessary information to do so.

ORBIS, since its beginnings as a manufacturer of energy efficiency solutions, has been developing devices to significantly reduce electricity consumption, because intelligent control of lighting and air conditioning systems allows us to make the most of natural resources and we can achieve savings of 35% (Source: IDAE- Contribution of electrical equipment to the energy efficiency of installations) in electricity bills.

Let’s see, in detail, how to introduce improvements in the electrical consumption of lighting.

Determination of the illuminance level

Illuminance or illumination level is the amount of light, measured in lumens, per surface area reached by that light.

We will use this measure to achieve the best visual performance.

This visual performance will depend on the activity taking place in the room in which we want to improve energy efficiency and should be set according to:

  • Visual acuity required according to the task to be carried out,
  • The environmental conditions
  • The duration of the activity.

It is worth carrying out a study of these needs, because we will create an optimal environment for work, for example, while saving on electricity consumption.

Introduction of saving mechanisms in lighting systems

Once the level of illuminance has been determined, it is a question of introducing efficient mechanisms in lighting management to adapt the lighting level according to the variation of sunlight and the presence of people in the different spaces (residential or tertiary), adjusting it to the needs of each moment.

These mechanisms can be divided into two groups:

  • Presence detectors
  • Movement detectors

Presence detectors

Presence detectors are solutions equipped with high-capacity sensors (ultra-sensitive lenses) that detect small movements while constantly measuring ambient brightness.

With the information obtained from this dual function, they switch off artificial lighting if natural lighting is sufficient, and switch it on if the level of sunlight is low.

Depending on the manufacturer and model, presence detectors are dimmable and can be programmed:

  • The detection area (area where the presence control will be carried out),
  • Timing (time in which the artificial light will be switched off once no presence is detected).
  • The light sensitivity.

Installation is very simple and can be carried out by embedding the device in the ceiling, on the surface (wall) or in a mechanism box, and some models even have the possibility of remote programming.

Where is it recommended to install presence detectors?

It is recommended to install presence detectors in places with long stays, for example: meeting rooms, offices, shops, hospitals, classrooms, warehouses, etc. where, thanks to their implementation, reductions in electricity consumption of between 13% and 50% can be observed.

Motion detectors

Motion detectors allow the selection of a minimum lighting level from which the artificial light must be switched on when it detects any type of movement, for example, the entry of a person into a room, and will switch it off once the desired time delay has elapsed.

There are devices for installation in ceilings, walls, corners or nooks and crannies; they can even replace existing manual switches in any room.

Where is it recommended to install motion detectors?

It is recommended to install motion detectors in transit or short stay areas, such as corridors, stairways, toilets, garages, courtesy lights, etc.

Incorporation of efficient light sources

Another factor to be taken into account to achieve energy savings is the selection of light sources or luminaires. Replacing the old ones with others with lower consumption will allow the functionality of the presence detectors and motion detectors to be used to the maximum, thus increasing the target savings.

How do I choose the most suitable system and model for my installation?

ORBIS manufactures a wide range of motion and presence detectors that allow us to have all the light we need when it is really necessary.  These products are easy to install and highly efficient, thus achieving the objective of savings, comfort and aesthetics in their design.

The motion and presence detectors have wide detection fields and the best quality lenses and other components, ensuring user comfort and the longevity of the product is guaranteed wherever they are installed.

The following comparative table allows, at a glance, to select the most suitable detector for each situation, taking into account: the angle and height of detection, the technology used, the timing range, light sensitivity, protection levels, maximum loads (luminaires) and remote management capacity.
