This, the fourth article in our series on green (sustainable) buildings focuses on the twin subjects of energy efficiency and water efficiency two fundamental areas of importance for green buildings. These are important not only because they reduce usage of and promote reuse of these precious resources, but because in so doing to minimize the building environmental impact. A well designed green building, can not only reduce its own environmental impact, but can improve a surrounding environment.
For new projects where the building site is not already decided, an important green consideration is the selection of a location for the building that fits into the existing urban fabric, especially the existing mass transit network of the city. Prospective sites should also be selected based on how easily they can integrate into the existing electric, gas, water, and sewage utilities. Fitting into a city’s existing infrastructure so that a project has the smallest impact on the existing energy, water, sewage and road systems is the first point at which the green decision making process comes into play. In addition to siting a green building should be oriented and landscaped to make the most of its site ant to integrate into the urban fabric so that it organically fits into it and enhances its surroundings. Orientation and landscaping can have major impacts on a buildings water and energy efficiency as well as on its environmental impact.
