Lumière naturelle

Le rôle que joue la lumière naturelle dans nos vies ne peut être surestimé, ce qui nous a conduit à mener des études approfondies sur l'éclairage naturel ces dernières années. Ces études nous ont permis de découvrir comment l'utilisation de la lumière naturelle peut transformer l'intérieur d'un bâtiment et améliorer le bien-être des occupants.

The experience of light

A considerable body of research shows that people prefer daylit spaces to those lacking natural light. Why should this be? If there is sufficient light to see, why would people prefer one source to another? To answer this question, we need to understand the evolved relationship between humans and natural light.

Starry sky

When viewing the night sky, most of us feel an intimate connection to the universe. Yet starry skies and moonlit nights have become increasingly rare for city-dwellers today. Given the harm that too much light at night is inflicting on human beings and ecosystems, it is time to reconsider our relationship to the ‘nocturnal side’ of our lives and our culture.

Daylight in the built-up environment

Over the last one and a half centuries, artificial light and the restructuring of working times have seemingly ‘liberated’ us from the diurnal cycles of light and dark that nature imparts on us. Yet recent research has shown that this separation from nature comes at a considerable cost, causing health and social problems. A reconnection to the rhythms of nature is therefore needed – and this will also have a profound influence on architecture.

All over the world, natural daylight has been exchanged for artificial light forms at the expense of our health and even productivity. With better building design, though, we can reclaim the daylight and improve well-being and performance.

How do you design and operate a healthy building? Answers to these questions can be found in an increasing number of methodologies and rating schemes that have seen the light around the world in recent years. They all share the ambition to strengthen the health and well-being of building users. Yet, they vary widely in terms of their overall scope, the metrics they use as proof of performance, and the weight that they put on the different phases in a building’s life cycle. The following chronological overview presents a selection of the most important and forward-looking tools, as well as their underlying methodologies.

To truly enhance human well-being, building design needs to move beyond optimising single parameters such as temperature and humidity, to more holistic approaches that take their cues in health-supporting human behaviours. Based on the Five Ways to Well-Being that have recently been established by scientists, this article outlines the way architects can consider these aspects in their designs, in order to nudge building users into a healthier way of living.

Daylight & Architecture

While the science of well-being is relatively nascent, the UK Government’s ‘Foresight’ project sheds a great deal of light on five factors that have a proven effect on well-being¹, leading to the definition of the Five Ways to Well-Being (connect, keep active, take notice, keep learning, give).² The question remains, though, how do we design buildings that can positively influence these five factors?

Tageslicht im Vergleich mit Kunstlicht – gibt es Auswirkungen auf die Lernumgebung?

Saviez-vous que les classes bien conçues ont une influence significative sur les résultats scolaires ? Dans cet article, nous examinons le rôle joué par les lumières naturelle et artificielle.

La nouvelle norme européenne EN 17037 traite de la lumière naturelle dans les bâtiments. Publiée fin 2018, c’est la première norme européenne à se concentrer exclusivement sur la conception et l’apport de lumière naturelle.
