In the small town of Montfoort, the first ten of millions of Dutch terraced houses have been converted into Active Houses. Their roofs harness the sun’s energy in three ways: to generate power, to supply heat, and as a source of light that significantly enhances the comfortable living conditions in these spacious but very deep houses.
Between 1945 and 1975, 2.5 million houses were built in the Netherlands, about 1.3 million of which were terraced houses. Many of these […]

Architectural design, ecological aspirations and a high standard of education enter into a close symbiosis in the Austrian federal state of Vorarlberg. For the young people who use it, the classrooms and corridors of the energy-efficient timber building offer plenty of room for movement and an abundant supply of daylight.
The secondary school in Klaus conceived by Dietrich | Untertrifaller set standards in this regard as long as 14 years ago. The architects have now supplemented the school with a […]

We all need a place to call home – a place to feel safe, sound and comfortable. However, feeling “at home” is not as straightforward as it used to be. The growing concern for global climate change has transformed the home into something much more complex and demanding. Today, the ability to be energy efficient while ensuring a healthy indoor climate has become the number one challenge in our building stock. And since we spend […]

How can we design buildings that stimulate our senses, follow our human needs and allow us to live in balance with nature? Buildings, which combine the use of daylight and artificial light and use the “double dynamic” potential of controlling daylight and artificial light, might stimulate our senses and human needs, as well as enhance the feeling of living in balance with nature.
Christina Augustesen presenting “Architecture for the Senses” at the 6th VELUX Daylight Symposium in London.
The Sense […]

Evolution has conditioned human beings to flourish in daylight. This is borne out by many involuntary functions we are unable to influence, such as the automatic adjustment of our eyes to brightness, distance and colour, our circadian rhythm of day and night, and, not least, the production of vitamin D through exposure of our skin to sunlight, an essential process for the regulation of bone growth and calcium levels in blood. Furthermore, the uplifting spirit that we all […]

In recent years, the interest in daylighting has experienced an unquestionable growth, not only among architects but also among the general public. At the same time, many people are also pursuing a healthier lifestyle, caring more about their bodies and their nourishment. If this weren’t true, how else could we explain the success of fitness centres and natural foods? In my opinion, this is a direct consequence of the saturation of the model that I call “artificial life”, […]

The question of successfully providing daylight to people has two distinct sets of solutions: We can try to get more people outside or more daylight inside of buildings. Ideally, we follow both approaches synchronously. In order to do so requires integrated urban design approaches that holistically address questions of creating comfortable outdoor spaces, providing sufficient amenities to accomplish high walkability levels (people have to do something outside) and finally accomplishing sufficient access to daylight within buildings. Such […]

Daylighting has always been an essential and irreplaceable resource in the field of architecture. It can be considered a resource from a design perspective, since it contributes significantly to the character and appearance of indoor spaces in buildings, due to such features as quantity, distribution and direction, through effects of light and shadow, and as a result of its variability in space and time.
It is a resource from an economic perspective, since daylight availability and the […]

It is desirable to design buildings with natural daylight and views to the outside, which can maximize passive solar heating, minimize electric lighting use and contribute to feelings of well-being and awareness. Unfortunately, the presence of daylight is not always a positive one. Excessive brightness, strong contrast or intense reflections from daylight can cause visual discomfort or the inability to perform tasks. Typically, the total amount of luminous flux […]

Can we imagine a house without windows? Probably not, yet we don’t seem to mind spending most of our lives in artificial environments, working, studying, meeting, shopping deep inside buildings where air and light are crafted by machines to create the most uniform and stable conditions.
We’ve strived to create the perfectly stable environment at work to avoid dis-tractions and enhance productivity. These conditions are sanctified by design recommendations, building regulations and energy […]

This weekend, remember to move your clock back and enjoy that extra hour of sleep on Sunday!
The last weekend of October is the time when we say goodbye to daylight savings time (DST) or summer time. The concept of daylight saving is dating back to 1895 and was first proposed by New Zealander George Hudson, and implemented for the first time by Germany and Austria-Hungary in 1916. Many more countries have started to use the concept […]

A starry night is one of nature’s most magical wonders. Yet in our artificially lit world, most of us no longer experience true darkness. In this talk based on his book THE END OF NIGHT, Paul Bogard seeks to restore our awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art. Using a blend of personal narrative, natural history, science, and astronomy, Bogard […]

This dissertation proposes a novel gaze-driven approach for dynamic discomfort glare assessments as a first step towards understanding human responsive comfort with respect to daylight. The objective was to observe the natural gaze behaviour in relation to glare for office spaces with the conditions implicitly constrained by real world luminous conditions. In the existing visual comfort models human behaviour is not sufficiently considered. These models employ only subjective assessments, which lack an […]
