FAQs About Sustainable Building Practices

How Do You Know if a Building Is Sustainable?

The simplest and most reliable way to gauge a building’s sustainability is by checking whether it has achieved LEED certification and, if so, at what level it has been certified. LEED certification serves as a clear and widely recognized indicator of a building’s environmental performance and sustainability. LEED building certifications are scored on a point scale and are as follows:

  • 40-49 points: LEED Certified
  • 50-59 points: LEED Silver
  • 60-79 points: LEED Gold
  • 80+ points: LEED Platinum

The higher the score, the more sustainable the building is.

How Does a Building Get LEED Certified?

To obtain LEED certification, a building project must undergo a structured process. It begins with project registration and the selection of the appropriate LEED rating system. The project team, comprising architects, engineers, and other experts, develops sustainable design strategies and collects documentation to demonstrate compliance with LEED criteria and credits. A third-party reviewer assesses the documentation, and if the project meets the necessary requirements, it can receive preliminary LEED certification.

What Is The Difference Between LEED and Green Building?

LEED is a structured and standardized certification program that falls under the umbrella of green building practices. Green building represents a broader commitment to sustainability in the construction and operation of buildings and can encompass various sustainability strategies, including those recognized by LEED.
