insideout Green building
Green building (also known as green construction or sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. This requires clo cooperation of the design team, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.

est building is the building that doesn't get built. New construction almost always degrades a building site, so not building is preferable to building. The cond rule is: every building should be as small as possible. The third rule is: do not contribute to sprawl (the tendency for cities to spread out in a disordered fashion).

Goals of green building
wareThe concept of sustainable development can be traced to the energy (especially fossil oil)
crisis and the environment pollution concern in the 1970s. The green building movement in the . originated from the need and desire for more energy efficient and construction practices. There are a number of motives for building green, including environmental, economic, and social benefits. However, modern sustainability initiatives call for an integrated and synergistic design to both new construction and in the of existing structures. Also known as , this approach integrates the building life-cycle with each green practice employed with a design-purpo to create a synergy among the practices ud.
Green building brings together a vast array of practices, techniques, and skills to reduce and ultimately eliminate the impacts of buildings on the environment and human health. It often emphasizes taking advantage of, ., using sunlight through , , and techniques and using plants and trees through , , and reduction of rainwater run-off. Many other techniques are ud, such as using wood as a building material, or using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water.
While the practices, or technologies, employed in green building are constantly evolving and may differ from region to region, fundamental principles persist from which the method is derived: , , , , , , and . The esnce of green building is an optimization of one or more of the principles. Also, with the proper synergistic design, individual green building technologies may work together to produce a greater cumulative effect.
