Buildings are where the majority people in modern societies spend most of their time, whether in homes, commercial buildings, industrial facilities or retail complexes. The design and construction of buildings require a large investment of time, money and other resources. Then they require additional resources for running costs and maintenance. Bad design can greatly increase energy consumption over the whole lifetime of the building. Fortunately, good building design can greatly reduce energy consumption during construction and ongoing throughout a building's life. - Description added by: David Lockie
