The real estate industry is playing a constructive role in addressing today's energy and global warming challenges. Developing buildings that use energy, water and other finite resources efficiently has essentially become the new normal in real estate markets for Class A commercial construction, be it office, industrial, multifamily residential, retail or lodging/hospitality properties.

A variety of companies and organizations are leading the way, with the results evident across the nation. Highlighted here are examples of companies, industry groups, and specific properties and portfolios that demonstrate the industry's commitment to real change and real results.
