Industry Response: Green, High Performance Buildings
What is Green Building? The creation and maintenance of a healthy built environment based on resource efficient and ecological principles.
Also referred to as High Performance buildings And sometimes referred to as Sustainable
Construction Architects refer to the process as Ecological Design or
Ecologically Sustainable Design.
Principles of Green Construction
1. Minimize resource consumption (Conserve)2. Maximize resource reuse (Reuse)3. Use renewable or recyclable resources
(Renew/Recycle)4. Protect the natural environment (Protect
nature)5. Create a healthy, non-toxic human
environment (Non-Toxics)6. Apply Life Cycle Cost Analysis (Economics)7. Pursue Quality in creating the built
environment (Quality)

Resources
Green Buildings (1) Energy
Passive Design: energy, lighting, envelope (skin, windows, door)
Renewable energy: solar HW, PV High efficiency: lighting, HVAC, transformers,
appliances Water
Low flow fixtures, greywater, rainwater harvesting, reclaimed water
Indoor Environmental Quality Zero emission finishes, properly sized HVAC,
attention to details (moisture control)
Green Buildings (2)
Materials Zero emissions Deconstructable, DFE Renewable, Recyclable, Recycled Content,
Reused Landscaping
Native and adapted species, low water use Construction Process
Low waste, protection of natural environment Contracting Process
Based on performance
Greening Movement in Construction
The U.S. Green Building Council is the major US force in greening the built environment
LEED: U.S. Green Building Rating System NAHB chapters engaged in green building New Urbanism and Sustainable Architecture are
rapidly increasing in influence Green Materials are becoming more prevalent Energy efficiency is increasing Healthy interior environments are critical
City Programs
Austin, Texas: A voluntary program that certifies green homes on a scale of one to four stars, with more stars being awarded to homes with more green features. The program also provides assistance to building professionals, such as architects, engineers, and builders, in exchange for offering and promoting green building practices.
Portland, Oregon: An integrated, conservation-based effort to promote resource-efficient building and sustainable site design practices throughout the City. Coordinating the expertise and resources of six City bureaus, this intiative sets aggressive goals and recommends a carefully selected set of strategies to leverage local expertise and develop cost-effective solutions for builders, developers, and building owners and users.
Concluding Thoughts Green building is a recent phenomenon and
movement (1993 in the U.S.) The main proponent in the U.S. is the USGBC
which created the LEED standard There is a rapidly emerging demand and market
for green buildings and products and services that support this new direction for construction
Federal, state, and local governments are creating a good percentage of the demand.
The private sector is rapidly coming on board, especially software, telecommunications, and aircraft industries.
