“Creating a healthy built environment based on ecologically sound principles”
Can be viewed as a subset of industrial ecology, but with characteristics that link it back to social, political, urban systems.
Major subset: 8% of GDP, 40% of materials consumption and 30% of energy resources.
Potential “Factor 10” reduction
Some ancient societies have persevered for many centuries by living in equilibrium, and in a sense of harmony, with the environment.
More technologically advanced societies have committed ecological suicide.
Technology may not offer the best answers.
We may wish to pursue an understanding of:
Lessons From Natural Systems:Ecosystems maintain resilience through diversifiedfunctions. Separate niches provide non-competitivelifestyles among different species.

State and Local Green Building Initiatives Committee
15 local and state entities, developing tools to disseminate information and help governing bodies create mandates and incentives for green building.
Primary implementation is in Europe; aim is to shift costs and physical obligations of production of goods from municipalities and individuals to producers themselves. Focus is on assigning responsibility to producers for mitigating / minimizing environmental impacts, with an emphasis on “upstream effects.”
Partnering system between government and business, aimed at reducing energy consumption of facilities through upgrades of building components, systems, and appliances.
Federal Energy Management Program: Greening Federal Facilities, Second Edition
Buildings must conform to “a project-specific point system that accounts for factors such as local fuel costs, climate, and construction costs for energy efficiency measures”
“Leadership in Energy and Environmental Design: Voluntary, consensus-based, market-driven initiative based on existing, proven technology. Whole building, entire life cycle, performance-oriented. Definitive standard for “green” building in US.
200,000 members in 800 local chapters. Pamphlet “Building Greener, Building Better” gives an overview of green design strategies and energy consumption improvements in residential construction. Fact sheets on environmental issues published for contractor education.
Energy-conservation orientation, promotes efficiency upgrades rather than construction-oriented initiatives.
Green Points New Home Program: requires selection among acceptable options for receipt of a building permit for new construction and additions over 500sf.
Green Points Remodeling Program: voluntary program encouraging homeowners with small projects to seek green solutions.
“…the first comprehensive program to encourage using sustainable building techniques in residential, multifamily, commercial and municipal construction.”
Provides technical assistance, program membership for building professionals, rating system, education and outreach.
“Seattle Public Utilities (SPU) partners with other government agencies, businesses, educational institutions, and non-profit organizations to promote sustainable design and construction practices and technology in the building and landscaping industries.”
Nomadic life & sparse requirements drove the architecture of the past and made it sustainable
These castles in Europe use small fenestrations to minimize heat loss
Alarming number of industries, poor living conditions, deteriorating environment mark the industrial era
The early & mid 20th century is characterized by:
New York the city of skyscrapers
Commerzbank headquarters in Germany by Architect Norman Foster uses garden terraces every 12 floors
‘Menara Mesiniaga’ by Ken Yeang in Malaysia is a revolutionary high-rise building design using sustainable principles
All things are connected like the blood that unites us, We did not weave the web of life. We are merely a strand in it. Whatever we do to the web, we do to ourselves.
Methods to Achieve Sustainability
Thurgoona Campus at Charles Sturt University in Australia. Consists of the School of Environmental and Information Sciences, a herbarium, computer network center, and accommodation cottages.
Used/recycled library shelving from a donor
Structural steel and glass
Minimal use of PVC piping in plumbing and may use ‘plumbing seconds’
Wool roof insulation
Wool and linoleum flooring
Non toxic paints and timber finishes
Mesh guards on vents provides protection from termitesBuilding Materials Cont.
Through the methods and materials used at Thurgoona Campus, energy consumption is reduced by 61%
