Why we deal with buildings..
In the United States, buildings account for; �! 41 percent of total energy use �! 65 percent of electricity consumption �
! 30 percent of greenhouse gas emissions�
! 30 percent of raw materials use �
! 30 percent of waste output (136 million tons annually) �
! 12 percent of potable water consumption ��

What are the milestones in a building’s life?
What do the buildings consume?
ENERGY WATER MATERIALS § Clay § Rocks § Sand § Wood § Metals § Glass § Concrete § Fiber § Paper § Plas3cs § Ceramics § …
NATURAL RESOURCES § Soil § Air § Water § Forests § Fossil Fuels § Sun § Wind § Oceans § Lakes, rivers § Ecosystem services § Heavy metal ores § …
What are the effects of the built environment?
Environmental Effects • Waste • Air Pollu3on • Water Pollu3on • Indoor Pollu3on • Heat Islands • Stormwater Runoff • Noise
Ul3mate Effects • Harm to Human Health • Environment Degrada3on • Loss of Resources
.. So, what is the remedy?
Green Buildings��
Green building movement is the most successful worldwide environmental movement ever! �
What is a Green Building?
Compared to a conventional building, a green building; �! uses less energy, water and natural resources�
! creates less waste�
! is smartly located �
! is built with as little impact on the land it sits on as possible�
! is healthier for the people living/working inside�
What is a Green Building?
! Green buildings consider sustainable practices throughout their life cycle from site selection up until demolition �
! Sometimes also referred to as ‘high performance buildings’ or ‘sustainable buildings’�
! Green buildings and green neighborhoods support the principles of sustainable development�
Why do we need green buildings?
Do Green Buildings increase initial costs?
YES and NO ! �
It depends on; �! Owner’s commitment for achieving green building goals�
! Project phase in which the decision for green building is taken�Site selection? Pre-design? Construction? Post-construction? �
! Integrated design �! 2 - 10% increase in total construction costs�
�
Integrated Design? Conventional Design-Bid-Build Process
How can we assess the ‘greenness’ of a building?
‘Green Building Rating Systems’ are developed to define and measure green buildings��! BREEAM (United Kingdom, 1990, BRE Group) �! LEED (U.S.A, 1998, U.S. Green Building Council) �! GREEN GLOBES (Canada, 2000, ECD Energy and Environmental Canada) �! CASBEE (Japan, 2005, IBEC) �! DGNB System (Germany, 2008, DGNB German Green Building Council) �! LEED Canada, LEED India, LEED Brazil��… many counties have their own rating systems� �
LEED “Leadership in Energy and
Environmental Design” LEED rating system developed by the U.S. Green Building Council (USGBC) is the most widely used rating system around the world �
LEED
LEED Rating System is applicable to the following types of buildings; �! New Construction �! Existing Buildings �! Homes�! Healthcare�! Hospitality�! Schools�! Retail�! Commercial Interiors�! Core & Shell�! Warehouses and Distribution Centers�! Data Centers�
LEED rating system is also applicable on the neighborhood scale �
LEED Rating Systems
There are five rating systems that address multiple project types; �
q BD+C (Building Design and Construction) �q ID+C (Interior Design and Construction) �q O+M (Operations and Maintenance) �
q ND (Neighborhood Development) �
q Homes�
LEED Credit Categories
Each rating system is made up of a combination of credit categories; �
1. Integrative Process�2. Location and Transportation �3. Sustainable Sites�4. Water Efficiency�5. Energy and Atmosphere�6. Materials and Resources�7. Indoor Environmental Quality�

LEED Score
There are four levels of certification - the number of points a project earns determines the level of LEED certification that the project will receive. Typical certification thresholds are�
40-49 points %: Certified �
50-59 points %: Silver �
60-79 points %: Gold �
80-110 points %: Platinum�
LEED certification level demonstrates a certain quantitative performance for the building in terms of�
- Energy use�- Water use�- Material use�- Effects on human health �- Occupant comfort�- Site use�- Waste generation �
