What Is A Leed Certified Building?

LEED, an abbreviation for Leadership in Energy and Environmental Design, is a non-compulsory program which allows a building to achieve recognition as a “green” structure. To do so, it must manage its resources in a way that is friendly to the environment.

The program began in 1998, and since then almost fifteen thousand buildings have been so recognized. Current predictions are that 10 percent or more new construction projects in 2010 will seek to be certified. Buildings are classified as Certified (the minimum level), Silver, Gold, or Platinum (the highest designation). As the classifications increase, so does the difficulty in meeting the point totals. Points are awarded based on lists in different categories, which are sustainable sites, energy and atmosphere, indoor environment, water efficiency, materials and resources, and innovation and design. Points are earned in the category of sustainable sites for various reasons.

These include habitat protection, utilization of open space, and light pollution. Access to alternative transportation, such as public transportation access, bicycle storage, and utilizing low emission vehicles, also falls within this category. Parking capacity and design of storm water drainage are included as well. Water efficiency involves how efficient a building is in its use of water for landscaping, how it handles waste water, and reduction in water usage. Energy and atmosphere focuses on refrigerant control, using renewable energy sources, and optimizing energy efficiency.

In the category of materials and resources, points are earned based on optimizing reuse of existing building components, controlling construction waste, and using recycled materials.

There are prerequisites that must be met in the category of indoor environment.

These are the control of tobacco smoke and meeting minimum air quality requirements.

Then, evaluations are based on the monitoring of outside air admitted, and the quality of the ventilation. Materials used, like paints and glues, must be those types classified as low fume. Employee comfort is also rated, with points for daylight, temperature, and views.

Innovation and design covers the engineering and architecture of the building. Factors evaluated include the carbon footprint, the use of fossil fuels, and the greenhouse gases emitted.

If the architect or engineer is LEED accredited, extra points may be awarded. Each type of structure has its own criteria. Complete neighborhoods can apply, as can existing commercial structures which are being renovated. Other types included schools, homes, commercial construction, and retail construction. LEED certification is not compulsory. Should a building wish to be certified, an application is submitted detailing which points have been addressed.

The process requires payment of certain fees for registering and if certification is granted.
Having a LEED certification will be a great way to expand your opportunities in fields related to the environment.
