What It Is
LEED (Leadership in Energy and Environmental Design) is a voluntary, performance-based green building certification framework developed by USGBC and verified by GBCI. It provides a holistic standard for sustainable design, construction, operations, and communities, using prerequisites, credits, and points across building lifecycles.
Key Components
- Core categories: Sustainable Sites, Water Efficiency, Energy & Atmosphere (highest weighted), Materials & Resources, Indoor Environmental Quality.
- Prerequisites (mandatory baselines, no points); elective credits (up to 110 points total).
- 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
Organizations pursue LEED for operating savings (20-30% energy reduction), market premiums (5-7% higher rents), ESG reporting, risk mitigation, and tenant attraction. It builds credibility via third-party verification, aligning with climate goals and incentives.
Implementation Overview
Phased approach: register, scorecard, design/commission, document, submit via Arc/LEED Online. Suited for all building owners/developers globally; requires integrated teams, modeling, commissioning. Certification demands rigorous documentation and audits. (178 words)
CSA Details
