CREATING BRIGHTER CITIES OF TOMORROW
By Jakob Schoof, Photography by Torben Eskerod
Daylight should always be considered when converting buildings. How can an approach of this kind be systematised? What new potential and synergies are created when we make daylight our starting point for the redevelopment of a building or district? A team of Danish architects has answered these questions in the recently published study ‘Hvad med Dagslys?’ (What about Daylight?).
The light of the sun contributes to human well-being and is an important source of energy [...]
DAYLIGHT MAPPING – PLANET EARTH
by Francesco Anselmo and John Mardaljevic
Astronomers and scientists have told us for some considerable time about the angle of the Earth’s axis to the sun, the direction and speed of rotation of our planet, the characteristic irregular distribution of land masses and oceans that defines our geographic knowledge.
Sixty years of space exploration and the images sent by a constantly increasing number of artificial satellites (there are more than 3,000 currently in orbit around the Earth) have strongly ingrained in our [...]
BIOMIMICRY IN ARCHITECTURAL DESIGN
by Michael Pawlyn
Most people now accept the case for sustainability and many wonder how the debate will move forward over the next few decades. Some commentators have asserted that biomimicry will be one of the main design tools that facilitate the shift from the industrial age to the ecological age of mankind. This rapidly emerging discipline draws on a sourcebook of solutions that have benefitted from a 3.8 billion year research and development period.
In this talk Michael Pawlyn will describe [...]

WHAT WINDOWS MEAN TO PEOPLE; INVESTIGATING PERCEPTIONS AND USES OF WINDOWS
by Bettina Hauge, DTU (Technical University of Denmark), MSc (anthropology), PhD (sociology), HD(A)-
Much research that involves windows has at its core daylight studies. This is natural, yet it may also reduce the properties and qualities of a window by indicating that all that matters in a window is daylight: the amount of solar influx. This, however, is not the only story. When people talk about their windows and express what the window means to them in their daily lives, it [...]

NEW BOOK ON THE DYNAMICS OF DAYLIGHT VARIABILITY
by Siobhan Rockcastle and Marilyne Andersen, EPFL, Switzerland.
Annual Dynamics of Daylight Variability and Contrast – A Simulation-Based Approach to Quantifying Visual Effects in Architecture
Daylight is a dynamic source of illumination in architectural space, creating diverse and ephemeral configurations of light and shadow within the built environment. It can generate contrasting levels of brightness between distinct geometries or it can highlight smooth gradients of texture and color within the visual field. Perceptual qualities of daylight, such as contrast and temporal variability, [...]
DAYLIGHT VISUALIZER NEEDS A LITTLE CORBUSIER
by Rasmus Brønnum, Arkitektens Forlag.
Software does not really need to be sexy and inspirational in itself, but the projects do. Maybe that is why until recently I have kept away from the free VELUX Daylight Visualizer programme. Even if you have developed a stable, well produced and process oriented tool, it is hard to get if off to a good start when it is only demonstrating projects without vision, looking like standard houses and prefabricated spaces.
We introduce it with Corbusier.

RAISE THE ORDINARY TO THE EXTRAORDINARY
by Will Bruder, FAIA, Architect in Phoenix
We often speak about daylight as a generic phenomenon rather than as a specific phenomenon tied to specific place and season. Many of my design colleagues work to amplify daylight’s seasonal scarcity at the latitude they build in while for our desert work daylight’s abundance is the challenge, its modest use the imperative. In any locale I see daylight as a dynamic sculptural material to be used to enliven space and enhance our experience [...]

MOMENTS IN ARCHITECTURE GENERATED BY LIGHT
by Anna Zagorec, Specialist in architecture and space planning
*Based on photos of architecture made during a stay in Portugal.
The buildings in Portugal are designed with great respect for the natural factors acting on the visual representation of the form, as good design is very much according to the typology. Thanks to this phenomena, architects can treat light as a factor creating moments in architecture.
Using the potential of daylight in architectural creation gives possibilities to forming shapes and bringing them to [...]

WE ARE DWARFS ON THE SHOULDERS OF GIANTS
by the VELUX Group
“We are dwarfs standing on the shoulders of giants”. This quote by Isaac Newton expresses the fact that each generation builds on the intellectual and material legacy of preceding eras. This is also the case in our cities, where the annual rate of new builds is less than 1%, and more than 65% of all buildings are more than 30 years old. We profit from this gigantic treasure of buildings and infrastructure while facing the challenge of [...]
DAYLIGHTING AT THE CROSSROADS
HEALTH AND WELL-BEING THROUGH RESIDENTIAL WINDOWS
by Dr. Jennifer Veitch, Senior Research Officer at National Research Council of Canada
Interest in daylighting and lighting design has never been higher since physiologists discovered a new type of cell in the human eye in 2001. These cells send information about light intensity to the brain centres responsible for controlling circadian rhythms to patterns of light and dark. This tells our bodies when to sleep (“It’s dark!”) and when to awaken (“It’s light!).
This discovery and related research led the Commission [...]
WHAT DOES IT REALLY MEAN TO DESIGN A HEALING SPACE?
by Vellachi Ganesan, Lighting Designer with Arup Singapore
What does it really mean to design a healing space? Not a clinical or medical space, but a healing space. This is a question that we recently asked ourselves as we embarked on the design for a community project- the Child Recreation Centre at the new Mae Tao Clinic.
The Child Recreation Centre is a space for all the children at the clinic, whether they are patients or children of patients, to come together, [...]
