Benchmarking the ‘sustainability’ of a building project
Since the early 1970s there has been growing concern about the probability of humankind, not only consuming more resources than the planet can provide (Goldsmith et al., 1972), but also polluting the planet’s ecosystems to a point beyond which they can
no longer repair themselves (Meadows, 1972). Reinforcing these early concerns came the oil crisis of the 1970s, the emerging problems of ozone depletion and climate change in the 1980s, and the dawning realization that, far from being part of the solution, buildings are a large part of the problem (Roaf, 2004b). The scale of these problems is being exacerbated by the rapidly rising global population, and increasing consumer expectations.
