Integrating “sustainable” or “green” building practices into the construction of state buildings is a solid financial investment. In an analysis of the financial costs and benefits of green building, this report finds that an upfront investment of less than two percent of construction costs yields life cycle savings of over ten times the initial investment.
There is now a large body of research, reviewed in this report, which demonstrates significant and causal correlation between improvements in building comfort and control measures, and worker health and productivity. However, these studies vary widely in specific measured correlations. Further, there has been relatively little work completed to evaluate specific, measurable benefits from green building design in California. The benefits are significant and not zero, but the data supports a broad range of calculated benefits – in contrast to the more precisely measurable energy, water, and waste savings.
