==History== [[File:Training meeting in an ecodesign stainless steel company in brazil.jpg|thumb|300px|right|The photo shows a training meeting with factory workers in a stainless steel [[ecodesign]] company from [[Rio de Janeiro]], [[Brazil]].]] <!-- Deleted image removed: [[File:i2amvaz.jpg|thumb|right|Reconstruction of an ancient house in the Greek city of [[Priene]]. {{deletable image-caption|Tuesday, 8 December 2009}}]] --> The first traceable concepts of environmental designs focused primarily on [[solar heating]], which began in [[Ancient Greece]] around 500 BCE. At the time, most of Greece had exhausted its supply of [[fuel wood|wood for fuel]], leading architects to design houses that would capture the [[solar energy]] of the sun. The Greeks understood that the position of the sun varies throughout the year. For a latitude of 40 degrees in summer the sun is high in the south, at an angle of 70 degrees at the zenith, while in winter, the sun travels a lower trajectory, with a [[zenith]] of 26 degrees. Greek houses were built with south-facing façades which received little to no sun in the summer but would receive full sun in the winter, warming the house. Additionally, the southern orientation also protected the house from the colder northern winds. This clever arrangement of buildings influenced the use of the [[grid pattern]] of ancient cities. With the north–south orientation of the houses, the streets of Greek cities mainly ran east–west. The practice of solar architecture continued with the [[Ancient Rome|Romans]], who similarly had deforested much of their native [[Italian Peninsula]] by the first century BCE. The Roman ''[[heliocaminus]]'', literally 'solar furnace', functioned with the same aspects of the earlier Greek houses. The numerous public baths were oriented to the south. Roman architects added glass to windows to allow for the passage of light and to conserve interior heat as it could not escape. The Romans also used greenhouses to grow crops all year long and to cultivate the exotic plants coming from the far corners of the Empire. [[Pliny the Elder]] wrote of [[greenhouse]]s that supplied the kitchen of the [[Emperor Tiberius]] during the year.<ref>{{cite journal|url=http://habitat.aq.upm.es/boletin/n9/amvaz.html|title=Una brevísima historia de la arquitectura solar|journal=Boletín CF+S|issue=9}}</ref> Along with the solar orientation of buildings and the use of glass as a solar heat collector, the ancients knew other ways of harnessing solar energy. The Greeks, Romans and Chinese developed [[curved mirror]]s that could concentrate the sun's rays on an object with enough intensity to make it burn in seconds. The solar reflectors were often made of polished silver, copper or brass. Early roots of modern environmental design began in the late 19th century with writer/designer [[William Morris]], who rejected the use of industrialized materials and processes in wallpaper, fabrics and books his studio produced. He and others, such as [[John Ruskin]] felt that the industrial revolution would lead to harm done to nature and workers. The narrative of Brian Danitz and Chris Zelov's documentary film ''[[Ecological Design: Inventing the Future]]'' asserts that in the decades after World War II, "The world was forced to confront the dark shadow of science and industry." From the middle of the twentieth century, thinkers like [[Buckminster Fuller]] have acted as catalysts for a broadening and deepening of the concerns of environmental designers. Nowadays, [[Efficient energy use|energy efficiency]], [[appropriate technology]], [[organic horticulture]] and [[Organic agriculture|agriculture]], [[environmental restoration|land restoration]], [[New Urbanism]], and ecologically [[sustainable energy]] and waste systems are recognized considerations or options and may each find application. By integrating renewable energy sources such as [[solar photovoltaic]], [[solar thermal]], and even [[geothermal energy]] into structures, it is possible to create [[zero emission]] buildings, where energy consumption is self-generating and non-polluting. It is also possible to construct "energy-plus buildings" which generate more energy than they consume, and the excess could then be sold to the grid. In the [[United States]], the [[Leadership in Energy and Environmental Design|LEED]] Green Building Rating System rates structures on their [[environmental sustainability]].
