Rachel Carson – Biologist with U.S. Bureau of Fisheries – Silent Spring, 1962 – Effects of DDT on the birds and the environment
Launch of Modern Environment Movement in the West & Globally
Environmental Movement • Environmentalist – During the 1960s, reject the modern world of large scale technological systems (corporations, political) in favor of a simpler, more primitive, and environmentally conscious lifestyle
• Counter Culture – opposition to corporate greed and American political system • Protests in support of native species, plants and animals

Commerzbank by Norman Foster, Completed 1997 Atrium of the Commerzbank showing sky gardens, above. The exterior skin of the building is designed with a double skin glass faรงade as shown on right. Expanding the meaning and role of the double skin glass faรงade, the sky gardens can be thought of as the interstitial space of an even larger width cavity.

Why Energy Efficient Technology • Support for Green Initiatives – Part of a larger scope, sustainable design
• External Driving Forces – Depleting Fossil Fuel (oil, coal, natural gas) – High cost of energy and escalating
Debis Building, Berlin, Potzdamerplatz Renzo Piano, 1998
• Growing interest in energy efficient buildings – Energy Efficiency driving goal
• Harness power of wind & sun
Global Warming • Greenhouse gases • Americans will use 44,000 pounds of CO2 per capita this year – Over three times world average
• We should strive for zero carbon dioxide emissions for our buildings – – – –
Rainwater storage Thermal loops Reclaimed water Solar & wind generated energy
Global Warming • 40% of all energy consumed in the US is for commercial and residential buildings • Government regulations need to address energy conservation measures to a greater degree • As energy prices climb higher, Greening becomes more economically feasible
Within the Framework of Sustainable Building • Risks • Buildings Consume – Raw Material – Energy – Capital
• Buildings Exhume – Pollutants
• Architects have a specific and significant roll in reducing risk
Sustainable Building Design • Nature of Architectural Decision Making • Contemporary concerns about effects of human activity – pollutants caused by human habitation
• Energy consumption – concept of reducing reliance on natural resources and fossil fuels – Dependence on renewable energy – Solar & Wind
Value of Green Building • Green Building can add a premium to building value • Productivity in ‘healthy’ buildings can account for .5% to 5% higher productivity • Green construction costs range from 2% to 10% higher than total cost of standard construction • Greater Occupant Comfort using less energy

Greg Katz Study for The Sustainable Building Task Force, over 40 California state government agencies, 2001
Benefits of Green Thinking • Support of Healthy Buildings – Natural Ventilation – Indoor Air Quality
• Better Building Envelope Performance • Reduction of energy consumption • Measure towards LEED™ certification
GSW, Berlin, Sauerbruch & Hutton
Considerations for Greening • Higher up front construction costs, – Approximately 20% to 50% higher per square foot of glazing
• Higher design fees • More planning time • Lack of government support, (till recently) - legislation • About 5% to 25% higher maintenance costs than standard curtain walls

Net Present Value
Net present value is the “present” value of an investment’s future financial benefit over a defined time interval, minus any initial investment cost. Where: - “Co” is the value of any initial investment (usually a negative value). - “ratei” is the constant “cost of capital” per unit of time (x.x%/yr). - “n” is the number of time units (i.e. years) over which value is being calculated. - “valuei” is the constant investment return per unit of time (in dollars).
