LEED Details
What It Is
Leadership in Energy and Environmental Design (LEED) is a voluntary, third-party verified green building certification framework developed by USGBC. It provides a performance-based standard for healthy, efficient buildings across design, construction, and operations. Scope covers all building types and phases; key approach combines prerequisites, elective credits, and weighted points.
Key Components
- Core categories: Sustainable Sites, Water Efficiency, Energy & Atmosphere (highest weighted), Materials & Resources, Indoor Environmental Quality, Innovation, Regional Priority.
- Up to 110 points total; prerequisites mandatory (no points).
- Rating systems: BD+C, ID+C, O+M, ND, Residential, Cities.
- Certification tiers: Certified (40-49), Silver (50-59), Gold (60-79), Platinum (80+).
Why Organizations Use It
- Reduces operating costs (energy/water savings 20-40%), boosts asset value (5-7% premiums), enhances occupant health/productivity.
- Meets ESG goals, accesses incentives, mitigates climate risks.
- Builds market differentiation, tenant demand, regulatory alignment.
Implementation Overview
- Phased: gap analysis, scorecard, integrated design, commissioning, documentation via Arc/LEED Online, GBCI review.
- Applies globally to commercial/residential; requires multidisciplinary teams.
- O+M enables recertification for continuous improvement.
