Green Building

Green Building is the practice of increasing the efficiency with which buildings use resources - energy, water, and materials - while reducing building impacts on human health and the environment, through better siting, design, construction, operation, maintenance, and removal - the complete building life cycle. Effective green building can lead to: 1) reduced operating costs by increasing productivity and using less energy and water 2) improved public and occupant health due to improved indoor air quality, and 3) reduced environmental impacts by, for example, lessening storm water runoff and the heat island effect (metropolitan area which is significantly warmer than its surroundings). Practitioners of green building often seek to achieve not only ecological but aesthetic harmony between a structure and its surrounding natural and built environment, although the appearance and style of sustainable buildings is not necessarily distinguishable from their less sustainable counterparts. Visit the website for more information.

Green Business

Green businesses operate in ways that solve, rather than cause, both environmental and social problems. These businesses adopt principles, policies, and practices that improve the quality of life for their customers, their employees, communities, and the environment. Visit the website for more information.

GreenGuardª

Established performance-based standards to define goods such as building materials, interior furnishings, furniture, cleaning and maintenance products, electronic equipment and personal care products with low chemical and particle emissions for use indoors. The standards establish certification procedures including test methods, allowable emissions levels, product sample collection and handling, testing type and frequency, and program application processes and acceptance. Visit the website for more information.

Hazardous Waste

Byproducts of society with physical, chemical or infectious characteristics that pose hazards to the environment and human health when improperly handled. Visit the website for more information.

High Performance Green Building

These buildings include design features that conserve water and energy; use space, materials and resources efficiently; minimize construction waste; and create healthy indoor environments. Visit the website for more information.

Hydroelectricity

Comes from the damming of rivers and utilizing the potential energy stored in the water. As the water stored behind a dam is released at high pressure, its kinetic energy is transferred onto turbine blades and used to generate electricity. This system has enormous costs up front, but has relatively low maintenance costs and provides power quite cheaply. In the United States approximately 180,000 MW of hydroelectric power potential is available, and about a third of that is currently being harnessed. Visit the website for more information.

Inorganics

Being, or composed of matter other than plant or animal. Visit the website for more information.

LEEDª

The Leadership in Energy and Environmental Design (LEED) Building Rating System sets industry standards for green building design. Visit the website for more information.

LEED Certification

Different LEED versions have varied scoring systems based on a set of required "prerequisites" and a variety of "credits" in the six major categories listed above. In LEED v2.2 for new construction and major renovations for commercial buildings there are 69 possible points and buildings can qualify for four levels of certification:

  • Certified - 26-32 points
  • Silver - 33-38 points
  • Gold - 39-51 points
  • Platinum - 52-69 points

LEED certification is obtained after submitting an application documenting compliance with the requirements of the rating system as well as paying registration and certification fees. Certification is granted solely by the Green Building Council responsible for issuing the LEED system used on the project.
Recently the application process for new construction certification has been streamlined electronically, via a set of active PDFs that automates the process of filing the documentation. Visit the Wikipedia website for more information.

Life-Cycle Assessment
