On the one hand, the great winter darkness is coming, on the other, high bills are expected due to expensive energy.
Carlotta de Bevilacqua, president and CEO of Artemide, and Paolo Brambilla, design curator of Flos, they explain how to best illuminate domestic environments, with attention to visual comfort, respect for natural balance and saving energy.
Patented anti-waste optics
"For Artemide the optoelectronic innovation to improve the efficiency of the luminaires is increasingly central, not only thanks to a constant update of the sources, but above all through the development of patented solutions that do not waste the emitted flux and maximize it, such as the technology of refractive optics now applied to many products", explains Carlotta de Bevilacqua, president and CEO of Artemide .
"This has led to concrete improvements in the new collections, even over 30 percent of the amount of light emitted with the same consumption, on many more technical lighting systems, but also on iconic products such as Tolomeo".
Light, only where and when it is needed
"In the lighting project, light must be increasingly free to be dosed, moved, modified", continues Carlotta de Bevilacqua.
"Light must be easily controllable through intelligent management, but also simply touched, oriented, adjusted with dynamic products such as Ixa by Foster + Partners, or brought where it is really needed with solutions such as Unterlinden by Herzog & de Meuron, which can be adjusted in height for reading or leave the freedom to distribute light points in the space in the chandelier version.
The product must have perfect and measured light parameters, but it must also leave the user free to interpret the lamps as needed. Calibrating the light in spaces with attention to waste is not penalizing, it can help to create more varied and dynamic light landscapes.
The good light that points to a contained energetic commitment can give back a lot, not only perception but also well-being, emotion, and today also support our health with Integralis sanitizing technology".
Lights in & amp; out for the well-being of man and nature
"Domestic light can also be interpreted with transversal solutions between internal and external spaces", continues Carlotta de Bevilacqua.
"Se | eS , for example, is a system free to be used outdoors or at home, it is a presence of light that does not disturb nature and also interacts when switched off with the environment thanks to the mirrored surface.
Or Funivia, a welcoming, minimal and light structure to bring light where it is needed, without distinction between indoor & outdoor".
Saving means first of all buying an indestructible lamp: "Sustainability does not only mean low consumption, but also the long life of the product, with a low environmental impact throughout its life cycle".
How to light interiors to feel comfortable (and save money)
"There has been a great change in the last ten years with the transition to LED sources, which are much more efficient than traditional light sources, but whose energy consumption still needs to be calibrated", says Paolo Brambilla, design curator of Flos with the Calvi studio Brambilla.
"It is always good to have the right light in the correct quantity and modality. Too often we see a waste of light, lighting used in an uncomfortable and non-ecological way, in the sense that it moves away from the physiological needs of our bodies and the environment.
Indoor, for example, it is important to be able to recreate an illumination that follows and respects our biological rhythms of wakefulness and sleep.
This mainly concerns work environments, for which we are studying systems with Flos that can meet the needs of comfort luminous, which also means saving energy.
Another context on which we are working a lot with Flos is outdoor lighting: outdoors there is a huge waste of light, which causes different types of problems. Artificial light used indiscriminately in the night interferes with the biorhythm of plants, insects and animals.
Outdoor lighting must also be calibrated for the well-being of our eye, which must continually balance the excessive contrast between the darkness of the night and artificial light".
Diffused light and accent lighting
"In general, an environment must be illuminated with a diffused light sufficient to be able to walk and orient oneself in the space, to be integrated with accent lights, which can have a decorative or functional value, when for example lights up a work surface", adds Paolo Brambilla.
"There must always be this balance between diffused light and accent light". Furthermore, visual comfort is achieved by calibrating the contrasts: "If you watch TV it is always good to have a small light that balances the brightness emitted by the screen".
The (every) presence of smartphones, computers, tablets and TVs has changed the way of lighting spaces: "For example, if you are at your PC, the work lamp is no longer necessary, but that's enough a pet light that illuminates the keyboard and helps define the area we are in. The only time in the house when we really need a full light is when you cooking".
Light temperature and color fidelity
"One of the parameters to choose the most suitable sources is the temperature of the light, measured in Kelvin degrees. At home we always suggest a warm light around 2700 degrees Kelvin", he continues Paolo Brambilla.
"Another interesting parameter is the CRI (Color Rendering Index), the color rendering index; the closer it is to 100, the more the light maintains its fidelity of colors.
A value therefore to be taken into consideration, for example, when designing a clothing store, but it also becomes crucial in the kitchen so as not to alter the colors of the food, or in the walk-in closet".
How to adjust the light: dimmer and turnable white
"Some lamps are equipped with dimmer to adjust the intensity, that is the amount of light emitted. Some models also have the turnable white control, to modulate the light temperature, and have a colder or warmer white depending on the activity.
The advice is to not mix cold lights with warm lights, it is not aesthetically pleasing, it is good to have all the light sources on the same Kelvin degrees, around 2700", concludes the design curator of Flos.
