Sustainable practices in the built environment are becoming a more common phenomona as market penetration of green buildings grow. Despite the reported benefits of green buildings, barriers to sustainability still exist. To motivate wider adoption of sustainable built environments, this research studies public policy and its impacts. The study aims to understand the links between public policy, construction playmakers' (e.g., organizations', institutions', business owners', and developers') motivation to build green, and growth of sustainable built environments in the United States. As a step forward in this direction, this paper focuses on the case of Michigan and explores construction playmakers' motivations to build and/or occupy sustainable buildings and how effective current public policy in Michigan is at addressing these motivations.There is little research on the links among legislation, construction playmakers' motivation to build green, and the growth of sustainable built environment in the United States. This article's findings show that: 1) green building costs are still the most frequently-reported barrier to green building, 2) property developers are significantly less likely to utilize green building practices than other construction playmakers, 3) single-family residential buildings were the least likely building type to receive green certifications, and 4) construction playmakers report low levels of green policy awareness and use despite the presence of relevant public policies. These findings will provide direction for policy makers and advocates in creating policy that will effectively promote green building construction.
