Lighting project for a WELL-certified kindergarten
Located in the city of Schwelm (Germany), the kindergarten has been entirely designed by the architectural team "Wilde + Wehnau" with
the reduction of the carbon footprint in mind during the design, construction and use process.
Different factors influence a building to obtain WELL certificates: correct ventilation, air and water quality, ergonomics of furniture and materials, thermal and acoustic comfort, family reconciliation policies, contact with nature, energy efficiency and, of course, correct lighting.
We will comment on the first points in passing, although it is not the subject to be dealt with, it is worth mentioning them, at least those visible in the images. Wood can be seen in all the installations as a constructive element, a good insulator, very necessary given the location of the work, which also arranged in slats as in the case of the ceiling, works as an acoustic insulator. In the case of the windows, of large dimensions, they contribute to illuminate the rooms in a natural way while preventing heat loss thanks to the double glazing that acts as a thermal barrier.
The illumination of the kindergarten, in charge of ONOK Lighting
, represents one of the relevant points. The different factors to take into account when we talk about a correct lighting, which complies with the regulations for buildings of this style, is:UGR index
A correct level of glare to avoid eyestrain or visual fatigue, this is achieved thanks to luminaire factors such as microprismatic diffusers, recessed points of light in the luminaire, linear lighting that distributes the luminous flux, various points of light distribution, and a wide variety of lighting points.
light per room and also to environmental factors, such as the presence of large windows and matte or low-gloss walls.In this particular case 2 types of luminaires are installed DRONE y LINER both can achieve a UGR level below 1
Color rendering index CRI
This factor depends entirely on the LED device and the ability of the light it emits to faithfully reproduce the colors in objects, being in this case high values, CRI >95 in both luminaires, very necessary for the type of construction,
un jardín de infancia.
Energy efficiency
No doubt a very important value, especially for the winter months in which, due to the geography of the kindergarten, there will be many days when artificial lighting will be needed. The LED efficiency of the Drone is almost 180 lm/W and in the case of the LINE R between 170 and 180.
lm/W depends on the color temperature, figures that will no doubt reduce the energy cost due to illumination.
Life cycle of the luminaire
Last but not least. As we mentioned at the beginning, a zero carbon dioxide emissions construction was proposed, and therefore the origin of the materials and their subsequent processing, once their useful life is over, acquires special relevance.
In this aspect, the different materials that make up the luminaires are mostly of recycled origin, as is the case of aluminum, up to 70% recycled, and of course recycled paper and cardboard for packaging and shipping documentation.
Our designs with electrical and electronic product components extend the life of the luminaire, we offer warranty
. extendable up to 5 years, and once it ends we ensure that its impact on the environment is mitigated.
