BOULDER, Colo.--(BUSINESS WIRE)--Green building certifications from programs such as Leadership in Energy and Environmental Design (LEED) and the Building Research Establishment Environmental Assessment Method (BREEAM) are quickly becoming the standard for the construction industry in many countries. While green building certification programs are well-known for their importance in new construction projects, a recent report from Pike Research forecasts that by 2020, nearly half the total certified footprint – 25 billion square feet – will comprise certifications for existing buildings. Pike Research’s study, “Green Building Certification Programs”, analyzes the current market and regulatory conditions related to green building certification programs and provides forecasts for the growth of this industry. The report includes an in-depth examination of green building drivers, barriers, and likely shifts in the underlying construction market. It also features profiles of major industry players including commercial real estate companies, trade associations, and green building councils as well as detailed descriptions of dozens of green building certification programs in operation around the world.
