DISCOURSE FORM AND IMPRESSION At the VELUX Daylight Symposium in Bilbao in the spring of 2007, the insightBY into how America treats its children gave particular cause for reﬂection. In Cal- ifornia, pupils are forced into derelict, shabby, unattractive rooms with no day- light. You don’t need to be a professor of psychology to realise that depressingKIM environments of this kind, with a complete absence of experience, lead to prob- lems with unhappy and maladjusted children. The atmosphere is evidence of aDIRCKINCK- lack of welfare provision that appears to be contagious. It is not surprising that the performance and happiness of the children improves by up to 25% when daylight is let into the rooms (as architect and researcher Lisa Heschong dis-HOLMFELD covered) – and, importantly, through windows that the children are able to see out of. Lisa Heschong’s research has produced clear evidence that daylight and a view are imperative for physical and mental health. But what about all the other factors that contribute to a complete spatial experience? How does our environment affect us? The town, the building, the room, the landscape – even the last is designed by humans. When it comes down to it, our entire environment is the work of humans. But is it also humane? Space plus form equals impressions. But how are they created? We know very little about this, and science can help us little in understanding more about it. There are too many factors that work together here. We need to develop different methods to ensure that architects and builders build for people instead of jump- ing on the next mega-trend in the international ﬂying circus of architecture. There is not enough research that is able to qualitatively analyse building environments and consequently provide support for planners and constructors. There are various approaches to this, but there is no real research carried out about the mental and emotional effects of architecture. At least we do know something about human behaviour in different types of urban space and under different climatic and cultural conditions. Among others, architect Jan Gehl and a network of urban researchers addressed this subject, and for a genera- tion, it has been one of the basic principles for avoiding social planning errors. Even if, in building projects, many other objectives often elbow this informa- tion out, there are also already certain guidelines for humane urban develop- ment based on a behaviouristic approach. But we still know little about what exactly goes on inside people. In many ways, architecture has become removed from its origins, in other words, the intention of creating a stimulating framework for human life. Mov- ing in time with technological development (and assisted by helpful comput- ers) we are faced increasingly with newer, more fantastic and seductive designs, that sprinkle a builder’s glittering magic dust over projects.

MANKIND Mankind as the focal point of architecture: By Richard Hobday AND ARCHITECTURE interior views of a corresponding relationship. Kept to within reasonable limits, direct sunlight is the best thing that nature can do for our health. Some of its effects have been known for thousands of years. This makes it all the more astonishing that physicians and architects have long reacted to this knowledge LIGHT AND LIFE with ignorance or rejection. And, all too often, this reaction remains unchanged. FROM THE SUN Medical practice has often had a direct and very profound inﬂuence on the development of architecture; and nowhere is this more evident than in the guiding principles of the Modern Movement. The ideas which ﬁrst informed Mod- ernism were formulated at a time when the building profes- sions were in the vanguard of a battle against tuberculosis. Throughout Europe, hundreds of thousands of people were dying each year from the `white plague’, which, although in retreat, was still taking more lives than smallpox, typhoid, scarlet fever and all the other infectious diseases of the era combined. Many of the pioneers of modern architecture were involved in the construction of tuberculosis sanato- ria. They were familiar with the medicine of their day and sometimes worked alongside doctors who used sunlight to cure their patients. In , the Nobel Prize for medicine was awarded to Dr. Niels Finsen, the Danish physician and scientist who discov- ered that ultraviolet radiation could heal Lupus Vulgaris, a form of tuberculosis thought to be incurable. Finsen’s Nobel Prize followed the discovery by two British scientists in that the sun’s rays could kill bacteria, and could do so having PHOTO: ERICH LESSING / AKG-IMAGES passed through glass. Their work prompted other scientists to investigate the eﬀects of exposing bacteria to the sun’s rays, and it was not long before sunlight was being hailed as `nature’s universal disinfectant’ and an important weapon in the ﬁght against infectious diseases. Sunlit rooms were held to be hygi- enic, while those that did not admit the sun’s rays were not.

This is clear from the book he wrote in the s on one of his later buildings; L’Unité d’Habitation or Marseille Block: “Doling out cosmic energy, the sun’s eﬀects are both phys- ical and moral, and they have been too much neglected in recent times. The results of that neglect can be seen in ceme- tery and sanatorium.” L’Unité d’Habitation was the realisation of the mass hous- ing schemes that had exercised Le Corbusier since the s. He designed L’Unité to alleviate a severe post-war housing shortage in France. This milestone of modern architecture is arranged for sunlight and incorporates many of the features of a heliotherapy clinic. Balconies on both the east and west facades serve as sunscreens or ‘brise-soleil’ that shade the apart- ments in the summer months. They are also what Le Corbusier called an ‘open-air extension’ of each living room. In addition, L’Unité d’Habitation has a terraced roof that provides ameni- ties for the residents, including a solarium. the decline of the sun – again Until the middle years of the last century, natural lighting PHOTO: KLAUS FRAHM / ARTUR largely determined the plan of a building and the design of its external envelope. But with the advent of low-wattage ﬂu- orescent tubes in the s, and air conditioning, reﬂective glass and cheap energy, the urban landscape began to change. Daylight was no longer a critical design element, as these tech- nological advances made lighting deep-plan buildings a prac- tical proposition. Medicine was changing too. Improvements in living standards led to a decrease in tuberculosis and rick- ets; and the arrival of antibiotics in the s meant that infec- tious diseases were much more amenable to treatment. This isPHOTO: PETE TURNER / THE IMAGE BANK / GETTY IMAGES reﬂected in hospital design where sunlit, airy wards came to be replaced by structures that were more complex, and were closed to the elements. Gradually, the emphasis shifted from putting hospital patients in wards that supported healing and prevented infection, to ones that created a comfortable and more convenient environment for patients and staﬀ. Sixty years ago, it was well recognised that sunlit wards have fewer bac- teria in them. Today it is not. However, strains of tuberculo- sis have emerged that are resistant to antibiotics, and one of D&A AUTUMN 2007 ISSUE 06 13
A hot bath relaxes body and mind – and all the more so if it is combined with a spot of sunbathing. Luminous intensi- ties of around 2000 lux and more stimulate the circadian system and the human psyche. the so-called `superbugs’ that infect our hospitals is becoming established in the wider community. The mrsa bacterium, or methicillin-resistant Staphylococcus aureus, has long been a serious problem in wards and nursing homes where it infects patients weakened by disease or injury. But a strain has emerged that can infect healthy young people who have had no prior hospital exposure. With drug-resistant bacteria posing an ever- greater threat to public health, sunlight’s germicidal proper- ties merit rather more attention than they receive. So too do the therapeutic properties of sunlit spaces. bright light In Greece and Rome, physicians called the emotion associ- ated with gloom and darkness `melancholia’; and the idea that lethargy, sadness and despair can be triggered by low light lev- els is certainly a very ancient one. During the s, scien- tiﬁc evidence emerged of a link between depressive illness andPHOTO: MICROZOA LIMITED / PHOTONICA / GETTY IMAGES light deprivation. Based on this and other more recent ﬁnd- ings, it has become clear that building occupants do not get enough bright light to have a positive impact on their health and emotional stability. The light levels required for this are much higher than those needed to perform visual tasks. Elec- tric lighting developed under the assumption that the only sig- niﬁcant purpose of light for humans is to see. Until recently, the impact of artiﬁcial light on physiological and psycholog- ical well-being was not generally considered. A major breakthrough came in , when scientists dis- Sensitivity to light and the covered a new sensory system in the human eye.

Although bright light is known to have health beneﬁts, and has been used to treat conditions such as seasonal aﬀective disorder (sad) and non-seasonal depression for some time, no one knows exactly how, or why, it works. The discovery of this new photosensitive system explains a great deal about the ways in which light aﬀects our well-being. 14 D&A AUTUMN 2007 ISSUE 06 15
