GREEN BUILDING TIMELINE Ένα ιστορικό της "αντίληψης των Πράσινων Κτιρίων", στις ΗΠΑ Πηγή: http//www.greenbuilding.com • Pre-20th Century – structures were designed and built by builder-architects who had an ability to understand the entire building from design through construction and lifetime operations. They incorporated enduring passive design and simple mechanical systems to heat, cool and light buildings. Architects in the 21st Century will look back upon these ideas to relearn the basics of climatic design. • 1930s – new building technologies began to transform urban landscape. Advent of air conditioning, low-wattage fluorescent lighting, structural steel, and reflective glass made possible enclosed glass and steel structures that could be heated and cooled with massive HVAC systems, thanks to availability of cheap fossil fuels. These technologies began a sadly regressive movement in architecture in which architects began to ignore climate issues and their effect on buildings and occupants. Increasing complexity in the industry also brought about specialization in professionals, leading to the loss of the generalists, the builder-architects. This specialization led to an increasing lack of communication between the professionals and therefore of lack of whole systems thinking in designing the various parts of the building. This problem will only begin to be addressed by the start of the 21st Century through the integrated design process. • 1970s, a small group of forward-thinking architects, environmentalists, and ecologists inspired by work of Victor Olgyay (Design with Climate), Ralph Knowles (Form and Stability), and Rachel Carson (Silent Spring), began to question the advisability of building in this manner. • 1973 – in response to energy crisis, American Institute of Architects (AIA) formed an energy task force, later the AIA Committee on Energy • 1977 – The Department of Energy was created to address energy usage and conservation • 1977 – Solar Energy Research Institute was founded (later National Renewable Energy Laboratory) in Golden, CO • 1980 - The Sustainable Buildings Industry Council (SBIC) was founded by the major building trade associations as the Passive Solar Industries Council...
