All of the costs in the Green Building Square Foot Costbook have been carefully adjusted for 2012. Included are government projects, commercial buildings, schools and libraries, medical facilities, residential buildings and recreational facilities. These projects all reflect the vast array of "green" materials and technologies being used today.

For each building, the Sweets Green Building Square Foot Costbook 2012 provides a detailed narrative describing the major features of the building, and what steps were taken to minimize the environmental impact both in its construction and its operation. All costs are clearly broken out on a cost-per-square-foot basis, along with the primary specifications and full details about the construction team.
