Healthier space need not be new space. In fact, some new buildings are extremely unhealthy as chemicals leach out into the air from glues, carpets, concrete and paint. There is no reason this must be the case. The cost to provide healthier environments is modest compared to the benefits. Healthier buildings reduce sick time and increase productivity, making it easier to recruit and retain employees. The results provided in this paper are based on a survey of over 500 tenants who have moved into either LEED or Energy Star labeled buildings managed by CBRE. This is part of a much larger study that includes details on operating expenses, leasing and management available from the authors or www.josre.org.
