Human Centric Lighting/3. HCL in learning institutions

1. Why is Human Centric Lighting (HCL) so important in schools?

The possibility to study in a comfortable, pleasant and well-illuminated environment increases academic performance. Several researches have demonstrated that the ability of students to focus in the classroom is influenced by a number of factors, such as the amount of daylight available in the room, adequate ventilation, the colour of walls, floors and furniture, and the absence of noise.

This is why, in schools too, it is important that lights follow Human Centric Lighting principles, putting users – teachers and students – at the centre of the lighting design. In other words, this means that fixtures installed in classrooms, laboratories and corridors, should be chosen not only to meet viewing needs, but also to create a study and work environment that is pleasant and functional, while also being energy-efficient and low-cost.

Quality lighting is also a fundamental element for the image and the prestige of a learning institution.  A school building fitting latest generation LED fixtures designed according to Human Centric Lighting criteria makes an excellent impression for a school that wants to have success, in an increasingly competitive market.

Human Centric Lighting is, above all, stable and evenly distributed, without glare and flicker, which not only has a negative impact on concentration, but also harmful for our eye health. Moreover, with the new LED fixtures, it is possible to provide different lighting levels according to different needs, such as reading, working at a computer, laboratory activity and for communicating with the teacher.

A very important advantage is the dynamic element of lighting that can be introduced in all the rooms of the school, like class rooms, labs, auditorium, and transit zones in order to prevent energy waste and increase the quality of light.

A dynamic light, in fact, can provide the right balance with the daylight coming from the windows and help teachers work better. During the first hours of the school morning, for example, a cold light helps keep students attentive and focused; with the passing of the hours a warmer light can have a relaxing effect on an agitated and hyperactive class, making students calmer and more willing to follow the lessons.

2. How to exploit the advantages of HCL in schools?

A lighting system that follows Human Centric Lighting criteria will take into account of the visual effects of light (lighting of the work area, of walls and rooms and average cylindrical illuminance), in accordance with applicable legal criteria, as well as emotional effects (impact on humour, attention and concentration) and biological effects (circadian rhythm).

All these factors play a key role when it comes to choosing the right lights.

3. How does it comply with lighting regulations?

There are two standards that govern the lighting levels in schools: UNI 10840 (Light and lighting – School rooms – General lighting for artificial and natural lighting) and UNI EN 12464-1 (Light and lighting – Lighting of work places – Indoor work places).

Standard UNI EN 12464-1 (see HCL in the workplace) is based on three fundamental criteria

  • Visual comfort (perceived sensation)
  • Visual performance (students can carry out their tasks in the most effective way possible)
  • Safety (lights don’t harm users’ eye health).

The other standard, UNI 10840, is more specific to school buildings and takes into consideration different aspects such as:

  • Luminance distribution
  • Lighting and uniformity
  • Glare and its reduction
  • Light colour
  • Maintenance
  • Energy saving
  • Lighting in the presence of video displays
  • Integration of daylight

4. Which lighting fixtures can be used to apply HCL in schools?

To obtain results above, we can choose LED fixtures with different characteristics and functions.

Ceiling/recessed lamps to illuminate the room with a wide luminance distribution

  • stable and well-distributed general lighting
  • good balance with daylight in all seasons
  • improve concentration (with or without computers, tablets)
  • ease communication (teacher’s lessons, students’ interventions)

Suspended lamp for direct/indirect lighting of desks

  • optimal lighting amount on a defined area (desk, blackboard, lab)

Direct/indirect lighting for wall washing or indirect lighting

  • decorating light for improved visual perception
  • lighting on the walls to highlight posters and other teaching media
  • optimal cylindrical illuminance

Dimmable systems, colour variations, lighting scene management
