Increasing urbanization throughout the world, the depletion of fossil fuels and concerns about global warming have transformed the city into a physical problem of prime importance. This book proposes a multi-disciplinary and systematic approach concerning specialities as different as meteorology, geography, architecture and urban engineering systems, all surrounding the essential problem of solar radiation. It collects the points of view of 18 specialists from around the world on the interaction between solar energy and constructions, combining territorial, urban and architectural scales to better regulate energetic efficiency and light comfort for the sustainable city. The main subjects covered are: measures and models of solar irradiance (satellite observations, territorial and urban ground measurements, sky models, satellite data and urban mock-up), radiative contribution to the urban climate (local heat balance, radiative-aerodynamics coupling, evapotranspiration, Urban Heat Island), light and heat modeling (climate-based daylight modeling, geometrical models of the city, solar radiation modeling for urban environments, thermal simulation methods and algorithms) and urban planning, with special considerations for solar potential, solar impact and daylight rights in the temperate, northern and tropical climates, and the requirement of urban solar regulation.

Thanks to the availability of energy, materials and technologies, the level of comfort in buildings is increasing around the world. However, today we are also facing buildings and cities that are responsible for a high percentage of global energy consumption. Pollution, heat island effect, climate change and global warming are just a few of the challenges that the human race, as well as other living matter on earth, will have to deal with in future. Moreover, as time goes by, we may not necessarily live in healthier conditions with better life styles. Within a limited period, this global and complex situation will need thorough, integrated and local surgery. This book is designed to draw greater attention to the sun and how a solar-climatic vision can influence and improve architectural design and urban planning. It may not have been discovered yet how small our planet is and how big the effect of a simple decision can be, but it is nevertheless important to be reminded of the sun not only as a powerful and perpetual actor in our dynamic atmosphere but also as a basis for figuring out a variety of adaptive solutions that must be identified and followed. In addition to the changes made by architects, clients and builders as well as planners, municipalities and all other persons who make decisions on plans, the role of those who live inside buildings and cities, not as users, but as producers and maintainers, also bear a certain degree of responsibility. Therefore, the optimization of new constructions, the modification of existing buildings and urban fabric should be considered on a global scale in regard to the sun as well as our future needs. The aim should be to improve energy-efficiency, health, comfort and safety in all living spaces, whether indoors or outdoors. In this respect, the analysis of the current situation, forecasting future scenarios and the development of intelligent alternatives are fundamental steps. In terms of energy efficiency, daylight provision and internal comfort, the use of advanced building materials and technologies as well as simulation tools can improve the building envelope and its performance. However, it is important to understand when, where and how they should best be applied to achieve an intelligent form as well as a responsive layout with a high level of performance for other essential aspects, too (e.g. structure, view, operation). Although today many consider “solar architecture” the attaching of solar thermal collectors and PVs to building roofs and facades, this is only one of the complex tasks which should be integrated in the design. In fact, solar architecture incorporates all the complexities of architecture on different scales. Besides, it has to respond accurately to certain issues resulting from the currently low price of other energy sources in many locations. In addition to the reduction of payments, other valuable improvements associated with solar-climatic considerations in the design should be clarified and compared. During the design process, an optimization (i.e. re-arrangement, re-orientation, re-sizing) of different elements, namely solar surfaces (i.e. transparent/opaque surfaces, shading/reflecting devices, collectors), building volumes and trees, does not necessarily increase the construction costs but can help identify deficient or over-designed elements. Alongside improving the energy efficiency aspects of individual buildings, a solar-climatic vision in planning can lead to other qualities for the benefit of small and large-scale living spaces, whether indoors or outdoors. Around the world, we must be prepared for more shocking news and annual records if many continue to build buildings, whether cheap or expensive, with little attention to the sun. In neighborhoods on an urban scale, the insufficient analysis and inaccurate decisions regarding building volumes and orientation can affect the potentials and performance of both internal and external spaces in terms of energy production, energy demand, daylight, health, comfort and safety for long periods of time. This book includes a decade of SOLARCHVISION practices on how architectural design and urban planning can be adapted by the constant path and variable effects of the sun in each location. Sharing such a vision can help architects, urban planners and clients to make more accurate decisions concerning energy and climate-related matters. After presenting fundamental diagrams in different cities around the world (e.g. the sun paths, solar radiation and temperature models), the role of an intelligent design for the building skin is described and analyzed in terms of finding a good relation between outside and inside as well as the direct and indirect collection of solar energy on different building surfaces. This research can bring about new appearances and structures for the creation of smart buildings and responsive cities. Aufgrund der Verfügbarkeit von Energie, Materialien und Technologien erhöht sich der Wohnkomfort in Gebäuden weltweit. Jedoch stehen wir auch vor dem Problem, dass Gebäude und Städte für einen hohen Anteil des weltweiten Energieverbrauchs verantwortlich sind. Umweltverschmutzung, Wärmeinseleffekte, Klimawandel und globale Erwärmung sind nur einige der vielen Herausforderungen, mit denen die menschliche Rasse, ebenso sowie alles weitere Leben auf der Erde, in Zukunft umgehen muss. In absehbarer Zeit wird diese komplexe globale Situation gründliche, ganzheitliche und örtliche Eingriffe erfordern. Dieses Buch richtet die Aufmerksamkeit auf die Sonne und dadurch auch darauf, wie ein solarklimatisches Konzept die Architektur und Stadtplanung beeinflussen und verbessern kann. Es ist vielleicht noch nicht entdeckt worden wie klein unser Planet doch eigentlich ist und wie groß der Einfluss einer einfachen Entscheidung sein kann, aber vor allem ist es wichtig, dass die Sonne eine wichtige und immer währende Rolle in unserer dynamischen Atmosphäre spielt und dies als Grundlage bei der Suche von Lösungsansätzen erkannt und angewandt wird. Neben Architekten, Kunden und Bauherren sowie Planern, Kommunen und allen anderen Personen die Entscheidungen über die Planung treffen, spielen die in den Gebäuden und Städten Lebenden auch eine Rolle, nicht als Nutzer, sondern als Erzeuger und Betreuer, und auch sie haben eine gewisse Verantwortung. Daher sollten alle Optimierungen neuer Bauten, Modifikationen von Bestandsgebäuden und Stadtstrukturen auf globaler Ebene Bezug auf die Sonne und auf zukünftige Bedürfnisse nehmen. Das Ziel sollte es sein, die Energieeffizienz, Gesundheit, Komfort und Sicherheit in allen Lebensräumen, ob drinnen oder draußen, zu verbessern. In dieser Hinsicht sind die Analyse der aktuellen Situation, die Prognose zukünftiger Szenarien und die Entwicklung intelligenter Alternativen grundlegende Schritte. Der Einsatz von modernen Baustoffen und Technologien sowie Simulationswerkzeugen kann die Energieeffizienz und Leistungsfähigkeit eines Gebäudes verbessern. Es ist jedoch wichtig zu verstehen wann, wo und wie sie am besten in der architektonischen Gestaltung angewendet werden können, um ein ansprechendes Layout mit einer hohen Leistung für eine Vielzahl von architektonischen Aspekten zu erreichen und in Bezug auf Energieeffizienz, Tageslichtversorgung und internen Komfort ein optimales Ergebnis zu erzielen. Obwohl heute viele schon das Anbringen von Solar-Kollektoren und PV-Modulen auf Gebäudedächern und Fassaden als "Solararchitektur" betrachten, ist dies nur eine der komplexen Aufgaben in diesem Feld der Architektur. Tatsächlich beinhaltet die Solararchitektur die gesamte Komplexität der Architektur auf unterschiedlichen Ebenen. Außerdem hat sie sehr genau auf bestimmte Sachverhalte zu reagieren, welche aus den vielerorts aktuell geringen Energiekosten anderer Energiequellen resultieren. Neben der Reduzierung von Baukosten sollten andere wertvolle Verbesserungen, resultierend aus solar klimatischen Überlegungen, im Entwurf hervorgehoben und verglichen werden. In der Tat kann eine Optimierung verschiedener Elemente während des Design-Prozesses, wie z.B. Solarflächen, Baukörpern und Bäumen, nicht notwendigerweise die Baukosten steigern, jedoch dabei helfen unnütze oder überdimensionierte Elemente zu identifizieren. Neben der Verbesserung der Energieeffizienzaspekte einzelner Gebäude kann eine zuverlässige integrierte solarklimatische Planung zu weiteren Qualitäten der Lebensräume führen. Überall auf der Welt müssen wir uns auf mehr und mehr schockierende Nachrichten und jährliche Rekordwerte vorbereiten, wenn weiterhin viele Gebäude mit wenig Aufmerksamkeit auf die Sonne gebaut werden. In Stadtteilen auf urbaner Städteebene kann die unzureichende Analyse und unklare Entscheidungen über Baukörper und Orientierung die Potenziale und Leistung interner und externer Räume im Bezug auf Energieproduktion, Energiebedarf, Tageslicht, Gesundheit, Komfort und Sicherheit auf lange Zeit beeinflussen. Dieses Buch enthält ein Jahrzehnt SOLARCHVISION Praktiken darüber, wie die Architektur und Stadtplanung mit dem konstanten Weg und den variablen Auswirkungen der Sonne an jedem Standort angepasst werden kann. Das Teilen dieser Vision kann Architekten, Stadtplanern und Kunden helfen, zielgenauere Entscheidungen über energie- und klimarelevante Fragen zu treffen. Nach der Vorstellung grundlegender Diagramme zu verschiedenen Städten auf der ganzen Welt (z.B. die Sonnenwege, Sonneneinstrahlung und Temperaturmodelle), wird die Rolle eines intelligenten Designs für die Gebäudehülle beschrieben und analysiert im Hinblick auf die Suche nach einer guten Verbindung zwischen Außen und Innen, sowie die direkte und indirekte Nutzung von Sonnenenergie auf verschiedenen Gebäudeflächen. Diese Untersuchungen können neue Ansichten und Strukturen für die Erbauung intelligenter Gebäude und anpassungsfähiger Städte hervorbringen.

The concept of cities as potential photovoltaic power plants is rapidly gaining prominence, but until now there has been no large scale study of the impacts of such development on urban fabric and infrastructure, or on inhabitants. This book, based on wide-ranging studies supported by the European Commission and International Energy Agency, is the first to properly address these issues. It sets out by looking at the implications on planning policy of PV in the urban environment, and giving an overview of the implementation and occupation processes. It then moves on to present detailed case studies from a range of European cites, examining the role of large scale PV installations in urban renewal and new urban area development stretching back over 15 years. It ends with a review of technical guidelines for PV, and regulation/legalities surrounding planning, building and grid connection. The book will form an essential resource for planners and developers who are considering including large scale PV in their plans and who want to understand what has (or hasn't) worked, and why.

Both the number and percentage of people living in urban areas is growing rapidly. Up to half of the world's population is expected to be living in a city by the end of the century and there are over 170 cities in the world with populations over a million. Cities have a huge impact on the local climate and require vast quantities of energy to keep them functioning. The urban environment in turn has a big impact on the performance and needs of buildings. The size, scale and mechanism of these interactions is poorly understood and strategies to mitigate them are rarely implemented. This is the first comprehensive book to address these questions. It arises out of a programme of work (POLISTUDIES) carried out for the Save programme of the European Commission. Chapters describe not only the main problems encountered such as the heat island and canyon effects, but also a range of design solutions that can be adopted both to improve the energy performance and indoor air quality of individual buildings and to look at aspects of urban design that can reduce these climatic effects. The book concludes with some examples of innovative urban bioclimatic buildings. The project was co-ordinated by Professor Mat Santamouris from the University of Athens who is also the editor of the book. Other contributions are from the University of Thessaloniki, Greece, ENTPE, Lyons, France and the University of Stuttgart, Germany.
