The Edge in Amsterdam, considered the greenest building in the world by BREEAM, the British sustainability rating agency, exemplifies how much better buildings can be. But there is a problem for green builders in this regard and that is the fact that they must build buildings in a place that allows them to take advantage of those natural resources (renewable energy). Katia Perini, architect, researcher and expert in green building in vegetative systems at the Urban Design Laboratory of the Earth Institute, said that green roofs are very effective in saving energy, improving air quality and helping to manage stormwater. Wind or solar energy upgrades allow facility owners to reduce electricity bills, which is crucial for large buildings that consume large amounts of energy.
Some practices, such as the use of local, renewable materials or passive solar design, go back thousands of years. The Anasazi in the southwest built entire villages so that all homes would receive solar heat during the winter. This, combined with the environmental movement of the 1960s and 1970s, led to the first experiments with contemporary green construction. Another green building strategy mentioned above is the construction of passive houses, whose standards were developed in Germany 23 years ago.
While a green building has been found to cost about 2 percent more than a non-green building, energy savings alone help recover the additional cost of the building in about six years. Green building is the practice of creating structures and using processes that are environmentally responsible and resource efficient throughout the life cycle of a building, from site to design, construction, operation, maintenance, renovation and deconstruction. The sensors collect data on how employees interact, building conditions and energy use, so that when there are fewer employees, entire sections of the building can be closed to save energy. The LEED (Leadership in Energy and Environmental Design), one of the most used certification systems for the design, construction, operation and maintenance of green buildings in the world, was developed by the U.
The WELL construction standard is a global program that focuses on the impact of the building environment on the well-being of occupants. Many building code offices also require that your zoning board grant you a conditional use permit or a modification of existing code before issuing you a building permit. Globally, buildings use 13.6 percent of all drinking water, so reducing water consumption is a key aspect of green building. To ensure that EPA buildings and practices reflect the mission of protecting human health and the environment, EPA continuously works to reduce the environmental impact of its facilities and operations, from building new, environmentally sustainable structures to improving the energy efficiency of older buildings.
