What is LEED?

A DESIGN TOOL Masterplanning

Schematic Design

Design Development

Construction Documents

Construction Administration

Post Construction Evaluation

Occupancy Monitoring of Systems

Encourages a high level of integration in the design process from the

very beginning of a project.

What is LEED? • environmental performance rating system of the U.S. Green Building Council

(USGBC), based partly on existing green building rating systems from Europe. – Evolving Benchmarking Tool

• voluntary, consensus-based, market-driven building rating system based on existing technology.

– Building Product Manufacturers; Building Owners, Managers, Users, and Brokers; Financial and Insurance Firms; Professional Societies; Design, Architectural, Engineering and Technical Firms; Contractors and Builders; Environmental Groups; Utilities; Universities and Technical Research Institutes; State, Local, and Federal Governments; Building Control Service Contractors and Manufacturers

• measurement system designed for rating new and existing commercial, institutional, and high-rise residential buildings.

– Other LEED systems are available for Homes, Existing Buildings, Commercial Interiors, Core and Shell, and Neighborhood Development

• performance-oriented system where credits are earned for satisfying each criterion.

• first released in 1998 with the first projects certified in 2000

From LEED Reference Guide 2.0, USGBC

Why LEED? An Owner’s Perspective…

Advantages to Owners:

• Government

– Federal, Military, State, Local

– One of the primary backers and a significant reason this push toward responsible design will

take hold

– Life Cycle cost is the primary selling point – the government tends to look further down the

road than most developers

• Colleges and Universities

– Advantages include:

• student and faculty recruitment

• quality of campus life / atmosphere

• fostering a learning environment

• putting the cash behind the teaching – learning labs

• Life Cycle costs - adaptability
