ARCH 3311 - Fall 2009


Buildings account for 48 of all greenhouse gas emissions
Buildings account for 48% of all Greenhouse Gas Emissions

Chlorinated Fluorocarbons (CFCs) that escape into the atmosphere to degrade the protective ozone layer around the earth


In a culture that has developed a problem of obesity,

our buildings have also become obese.


48%

U.S. CO2 Emissions by Sector

U.S. Energy Power Consumption by Sector

76% of all power plant generated electricity is used just to operate buildings !!

What is sustainable design

Sustainable Design

What isSustainable Design?

a system of development that accommodates human needs without diminishing natural resources for future generations to meet their own needs.


Perpetual Natural Resources

Virtually inexhaustible on a human scale

Solar, Wind, Tidal, Gravity

Renewable Natural Resources

Resources that can be replenished through natural processes in a relatively short time:

Water, Timber, Grasses

Non-Renewable Natural Resources

Resources that require thousands of years to replenish:

Coal, oil, natural gas

How do we verify these claims of green buildings?

The need for an evaluating matrix:

LEED

What is LEED?

Leadership in Energy and Environmental Design

US Green Building Council

started in 1993 is non-profit organization of Architects, Builders, Realtors, Building Owners, & Environmentalists working together to establish Green Building standards

Product life cycle assessment
Product Life-Cycle Assessment

The process that investigates the energy impact of a product at every stage of it’s life, from development to obsolescence.

Cradle to Cradle Certification

provides a company with a means to tangibly, credibly measure achievement in environmentally-intelligent design and helps customers purchase and specify products that are pursuing a broader definition of quality. This means using environmentally safe and healthy materials; design for material reutilization, such as recycling or composting; the use of renewable energy and energy efficiency; efficient use of water, and maximum water quality associated with production; and instituting strategies for social responsibility.

If a candidate product achieves the necessary criteria, it is certified as a Silver, Gold or Platinum product or as a Technical/Biological Nutrient (available for homogeneous materials or less complex products), and can be branded as Cradle to Cradle.

Building life cycle costs
Building Life-Cycle Costs

  • First cost

  • Maintenance cost

  • Energy Consumption cost

  • Replacement costs

Most Europeans buildings have a far different paradigm on life cycle costs than buildings in the United States.

Buildings in the United States are typically built for investment or sale


Architects know firsthand that most buildings can be designed to operate with far less energy consumption than the average U.S. building does, at little or no additional upfront cost by proper…

  • building geometry

  • glazing location and properties

  • material selection

  • configurations for natural

The rampant growth of the green building movement has brought with it the unsavory practice of “greenwashing.” Greenwashing typically refers to the practice of making unsubstantiated or misleading claims about the environmental benefits of materials, finishes, or systems. This has also resulted in the inaccurate perception that sustainability/green design can merely be an add-on to our buildings rather than through an integrated design approach.
