GREEN BUILDINGS Zeynep ÇAKIR, MSc, LEED AP BD+C November, 2014

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 �
