A lecture on leed that is an internationally recognized green building certification system

1. Leadership in Energy and
Environmental Design
LEED

2. What are Green Buildings ?
Green Building, also known as green construction or sustainable building,
is the practice of creating structures and using processes that are
environmentally responsible and resource-efficient throughout a building's
life-cycle: from site selection, to design, construction, operation,
maintenance, renovation, and deconstruction

3. Benefits:
• 15% of Gross Domestic Product or GDP per year
Green building is a source of significant economic and
environmental opportunity.
• Reduce CO2 emissions by 33 – 39%
• Reduce water usage by 40%
• Reduce Energy Usage by 24 - 50%

4. Leadership in Energy and Environmental Design LEED
is an internationally recognized green building certification system, providing third-party verification that
a building or community was designed and built using strategies aimed at improving performance
across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction,
improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

5. LEED – Leadership in Energy and Environmental Design Goals of LEED is to promote integrated, whole-
building design practices, recognize environmental leadership in the building industry, stimulate green
competition, raise consumer awareness of green building benefits, transform the building market.
An LEED building is rated based on :
• Sustainable Sites
• Water Efficiency
• Energy and Atmosphere
• Materials and Resources
• Indoor environmental quality
• Innovation and Design process

6. A project can be LEED certified .A product can’t be LEED certified. But a
product can contribute to achieve LEED certification for a project.

7. LEED Rating System
• LEED is a voluntary, internationally recognized green building certification system
• Offers third-party verification that a building or community was designed and built aimed at improving
performance and reducing environmental impact
• Provides building owners and operators a framework for identifying and implementing practical and
measurable green building solutions
• Can be applied to any building type and any building lifecycle phase
• LEED is flexible enough to apply to all building types – commercial as well as residential. Homes
Neighborhoods Commercial Interiors Core and Shell New Construction Schools, Healthcare, Retail Existing
Buildings, Operations and Maintenance

8. LEED system goals
The goal of LEED is to create better buildings that:
•Reduce contribution to global climate change
•Enhance individual human health
•Protect and restore water resources
•Protect and enhance biodiversity and ecosystem services
•Promote sustainable and regenerative material cycles
•Enhance community quality of life
LEED is a holistic system that doesn’t simply focus on one element of a building such as energy,
water or health, rather it looks at the big picture factoring in all of the critical elements that work
together to create the best building possible. In fact, 35% of the credits in LEED are related to
climate change, 20% of the credits directly impact human health, 15% of the credits impact
water resources, 10% of the credits affect biodiversity, 10% of the credits relate to the green
economy, 5% of the credits impact community and 5% of the credits impact natural resources.

9. Types of LEED projects Definitions
LEED is for all building types and all building phases including new construction, interior fit outs,
operations and maintenance and core and shell.
Existing Buildings: Operations & Maintenance (EB O&M)
LEED for Existing Buildings: Operations & Maintenance provides a benchmark for building owners and
operators to measure operations, improvements and maintenance.
New Construction (NC)
LEED for New Construction and Major Renovations is designed to guide and distinguish high-performance
commercial and institutional projects.

10. Commercial Interiors (CI)
LEED for Commercial Interiors is a benchmark for the tenant improvement market
that gives the power to make sustainable choices to tenants and designers.
Core & Shell
LEED for Core & Shell aids designers, builders, developers and new building owners
in implementing sustainable design for new core and shell construction.
Homes
LEED for Homes promotes the design and construction of high-performance green
homes.
Neighborhood Development
LEED for Neighborhood Development integrates the principles of smart growth,
urbanism and green building into the first national program for neighborhood
design.

11. Types of LEED projects Definitions
Schools
LEED for Schools recognizes the unique nature of the design and construction of K-12 schools and addresses
the specific needs of school spaces.
Retail
LEED for Retail recognizes the unique nature of retail design and construction projects and addresses the
specific needs of retail spaces.
Healthcare
LEED for Healthcare promotes sustainable planning, design and construction for high-performance healthcare
facilities.

12. Certification level for LEED
LEED has 4 levels of certification
Projects go through a verification and review process by
GBCI and are awarded points that correspond to a level
LEED certified: 40-49 points
Silver 50-59 points
Gold: 60-79 points
Platinum: 80+ points).

13. • The Green Building Certification Institute (GBCI)
oversees and manages LEED certification for projects
registered under any LEED Rating System. The
process include
o Choose a Rating System
o Project Registration
o Prepare Application
o Submit Application
o Application Review
o Certification

14. Why have a LEED certification ?
A rapidly-growing number of private sector organizations and governments are adopting LEED certification
in their policies, programming and operations, with the goal of achieving and demonstrating sustainability.
Also, a LEED certification may have a payback only by the cost saving in energy for a project when you
achieve the certification.

15. Advantages
• Resources are used more efficiently
• Creates healthier working environment for employees resulting in more
productivity and comfort
• Cleaner water and air
• Less Waste
Disadvantages
• Higher initial cost (that’s about it)
