As energy prices increase, there is a great deal of focus on switching to more sustainable solutions. LED luminaires with lighting control is one of those – and it is an investment that brings immediate benefits.

High-quality LED lighting is energy-efficient, producing a lot of light in relation to the energy used. Compared to fluorescent luminaires, not only is the energy consumption significantly lower, but the lifetime of LED luminaries is longer as well. By adding CLO (Constant Light Output), your lighting solution can then be further optimised.​

This lighting solution recipe fulfills all rules and regulations but does not reach our HCL requirements at Fagerhult.

This lighting solution recipe reaches level 3 on the biological or emotional scale and therefore fulfills our HCL requirements at Fagerhult.

When we create electric lighting we are inspired by daylight. The result is healthy indoor environments that influences the visual, biological and emotional effects of light. The biological and visual aspects of light also have the ability to affect our emotions. The minimum requirements of these visual and room-creating effects are clearly regulated today through the lighting standard and legal demands.

Human Centric Lighting, or HCL, is light that balances the visual, biological and emotional effects in humans. It requires tailor-made solutions that are based on the specific environment and needs of the people who live and work in it. It requires an approach that takes into account all aspects of the human relationship to light: the visual task as well as our physical, psychological and emotional needs.

In this tool, all lighting solutions that reaches level 3 on either the biological or emotional scale in the recipe, fulfills Fagerhults demands for a Human Centric Lighting solution.

Energy savings compared to equivalent luminaire without CLO

Luminaires with Constant Light Output (CLO) contribute to more optimised and sustainable facilities by reducing over-illumination. In turn, this means less installed output and it can, in some cases, even require fewer luminaires. The ultimate result is, of course, the energy saved – a benefit for both the environment and your finances.

With LEDs, the luminous flux decreases over time as the diodes are being used. This light depreciation is more or less linear across the diode’s service life. However, the luminaire itself can compensate for this loss using a programmable driver. This is known as Constant Light Output (CLO).

Do you wonder why you can't tweak your own presence level in this example? It's all about the EN 15193-1 standard Energy performance of buildings – energy requirements for lighting. This standard takes a real-world approach, assuming an average occupancy of 60 % in individual offices, calculated over 2500 hours per year, for an individual office.

Why then the 60 % number for presence? The default absence factor of 40 % accounts for example for meetings, breaks, and those times your office is empty. The idea is to make your lighting as practical as your office life. So, while you can't change your presence level settings, it's all in the name of smarter, more efficient lighting that matches how your space is really used. Of course, different types of lighting control settings and individual presence levels in a specific project also affect the end result.

The energy consumed during operation contributes to the greatest environmental impact of luminaires. On the other hand, if you use lighting controls so the light is only turned on where people actually are located, you can save a great deal of energy - and use the earth’s resources more sustainably.

Organic Response is a wireless plug-and-play system developed for entire buildings. The sensors integrated into each luminaire are easily connected – and without commissioning or programming, you get a smart and energy-efficient lighting control system based on presence detection.

Our examples illustrate the amount of daylight equivalent to that of southern part of Sweden. These calculations take latitude into account, but not the direction of the windows. The amount of daylight is project specific and influenced by geographic position, the building's orientation, the size/type of windows, and other factors.

There are different ways to control the light. Here’s a brief summary.

You have now created your own lighting solution for an individual office. The result is a room enabling focused work and stillness. It provides an optimised environment throughout the day – and is the ideal spot for creative minds to find solutions for a sustainable future.

In any lighting solution, every choice has an impact and comes with advantages as well as disadvantages. The solutions you can create in our tool contain archetypes of lighting products such as recessed, pendants, wallwashers, and spotlights. Your choices are evaluated by a set of well-calculated parameters.

This Recipe of Light has been created together with a Fagerhult sales representative. If you are pleased with your results, you can share your solution with your colleagues. Enjoy your Recipe of Light!

Increased levels of light at the right time of day makes us more alert and less tired. A boost of light in the morning, for instance, raises your cortisol production and suppresses your melatonin, giving you a balanced energy level lasting the entire day and creating the base for a good night’s sleep. This can be measured by the melanopic lux level that reaches the eye.

The recipe has a very low biological impact since the vertical lighting levels meeting the eye are not high enough.​

The recipe has a low biological impact since the vertical lighting levels are insufficient and would need a longer exposure time.​

The recipe has a medium biological impact since the vertical lighting levels are sufficient but not more than that.​

The recipe has a high biological impact since the vertical lighting levels are sufficient, and the recommended exposure can be reached within a few hours.​

The recipe has very high biological impact since the vertical lighting can be precisely dosed when and where needed.

The impact on climate change in our tool is related to your solution’s energy consumption. This means that the embodied carbon of the luminaires themselves is not considered in your recipe of light. The LENI (Lighting Energy Numeric Indicator) number that indicates energy use is calculated, and the result displayed is in accordance with its contribution to greenhouse gas emissions.

The recipe has a very low impact on climate change. Way to go!

The recipe has a low impact on climate change. You have made insightful choices.

The recipe has a medium impact on climate change. This is good, but perhaps you could improve it?

The recipe has a high impact on climate change. Maybe you need to re-evaluate some of your choices?​

The recipe has a very high impact on climate change. The environment is of concern to any lighting solution, so perhaps you should consider more controls?

If the lighting in a room is not changing in terms of direction, intensity, uniformity or colour temperature, people will experience no differences during their day since they are only exposed to one constant, even lighting. From an emotional perspective, this is not a good thing. What successful lighting design should provide is also emotional values, helping to express how it should feel to be in the room.

The recipe has a low emotional impact since the even lighting will be tedious and give you the feeling of a rainy day.

The recipe has a fairly low emotional impact since the even lighting only has minor variations, similar to the feeling of rather a dull day.

The recipe has a medium emotional impact since it provides reasonably dynamic lighting – it feels like the sun is about to break through.

The recipe has a high emotional impact as we use varied task lighting, even ceiling luminance and bright vertical lights – here the sun is breaking through.

The recipe has a very high emotional impact, with its varied task lighting and ceiling illuminance that follows the rhythm of the day. It feels like taking a walk in the woods on a sunny day.

The energy use has a direct influence on your overall lighting quality, but also on your electricity bill and the environmental impact. Increased lighting comfort and additional lighting experiences ​increase the use of energy – and so there needs to be a balance between what is good ​lighting for people and what is good lighting for the environment. 

The recipe has a very low energy cost – great effort.

The recipe has a low energy cost. You have made conscious choices – well done.

The recipe has a slightly higher energy cost. This is good, but perhaps you could find some more energy-efficient alternatives?

The recipe has a high energy cost. Perhaps there are some choices that you should re-evaluate?

Our constant ambition is to offer premium solutions with value for money. A varied and dynamic lighting solution focuses on the well-being of the people being in an indoors environment. This naturally increases the luminaire investment, which includes the luminaires themselves, the controls, and the maintenance. Adding controls increases the initial investment, but over time, it also decreases the energy use and the environmental impact.​

The recipe has a low investment rate. Perhaps there are some elements you should consider further?

The recipe has a fairly low investment rate. This is good, but maybe there are some things being overlooked?

The recipe has a fair investment rate. You have taken many factors into consideration – well done.

The recipe has a fairly high investment rate. This is a well-balanced solution for increased well-being.

The recipe has a high investment rate. This is great as you have created an optimal light environment.

The visual aspects of light include traditional and fundamental values, such as the visibility of an object achieved through contrast, glare reduction through ambient lighting, and luminaires being correctly placed. Visual comfort is the most important lighting quality as it makes us able to effortlessly perceive the world around us.

The recipe has a low visual quality with unvarying light reducing contrasts and textures.​

The recipe has a fairly low visual quality, but the heightened glare reduction increases the balance between the light source and the background.

The recipe has a medium visual quality as the added ambient illuminance increases the visual comfort.​

The recipe has a high visual quality and comfort, enhanced by the added directionality and ambient lighting.​

The recipe has a very high visual quality, with sufficient task lighting and ambient lighting, plus some extra sparkle. Here you have a perfect solution.​
