Q: What is green building?
A: Green Building is the practice of increasing the efficiency with which buildings use resources while reducing building impacts on human health and the environment.
Green building practices aim to reduce the environmental impact of buildings. As of 2006, buildings used 40 percent of the total energy in both the European Union and the United States. In the US approximately 54 percent of energy consumption was from residential buildings and 46 percent from commercial buildings.
Green building practice is a big step toward a stable and sustainable future. Utilizing green building practices on your next construction project will only cost approximately 5 percent more than conventional construction projects, but reduce the environmental impact of buildings significantly.
Examples of green building practices include using sunlight through passive solar, active solar and photovoltaic techniques and trees through green roofs and rain gardens- all of which emphasize taking advantage of renewable, natural resources. Materials commonly used in green building practices, such as bamboo and straw are from forests certified to be sustainably managed.
Not only will green building practices reduce negative affects on the environment, it will save homeowners and businesses owners' money in the long run by reducing energy and overall operating costs. Increasing the building's asset value along with tax rebates and zoning allowances are just a few of the incentives for people to incorporate green building practices into their next construction project.
Throughout the world, countries have developed their own standards of energy efficiency for buildings and implemented a green building rating system. The United States' rating system consists of LEED project certification and the Green Globes system, a revolutionary building environmental design and management tool.
Other examples of green building materials include, dimension stone, recycled stone, recycled metal, and other products that are non-toxic, reusable, renewable, and/or recyclable. As stated on the U.S. Green Building Council's website website, "LEED certification provides independent, third party verification that a building project meets the highest green building and performance measures."
Commercial buildings as defined by standard building codes are eligible for certification under the LEED standard include -but are not limited to- offices, retail and service establishments, institutional buildings, hotels and residential buildings of four or more habitable stories.
Behind the implementation of LEED is the U.S. Green Building Council (USGBC), a non-profit trade organization that promotes sustainability in how buildings are designed, built and operated. Best known for the Leadership in Energy and Environmental Design (LEED) rating system, USGBC promotes buildings that are environmentally responsible and profitable.
The New Orleans Chapter of the USGBC, also known as The Emerging Green Builders (EGB-NOLA) "promotes environmental awareness and sustainability in the built environment through leadership, policy change and education by organizing and supporting a network of students and young professionals in Post-Katrina New Orleans."
The Holy Cross project in New Orleans is a perfect example of green building with net zero electricity, solar power, recycled wood, low VOC paints, and LEED Platinum Certification. This particular project consists of 5 single family homes, an 18 unit apartment building and a community center. To read more about this project visit the Louisiana chapter's blog.
Across the country in Seattle, construction has begun on the $500 million Bill and Melinda Gates Foundation campus, a 900,000 -square -foot project. The campus will be one of the largest energy-efficient projects in Washington State. Even the campus garage will sport a one-acre "living" roof seeded with a hearty plant called sedum that will reduce rainwater runoff.
This project's estimated date of completion is 2010 and is just one of the many non-profit organizations tuning in to green building practices. The number of non-profit organizations focusing on green building practices is expected to increase as the government limits funding to those not building to LEED standards.

In urban settings, such as Seattle and New Orleans, green practices are becoming more important to the survival of our environment and the quality of life for those living in the areas. As New Orleans rebuilds and Seattle continues to develop at a rapid rate, green practices are going to become a standard for building.
The positive affect that green practices have on the environment is generally underestimated, while the cost of implementing these practices is overestimated. So whether you are building a new home or a new business, do your research- not only will you be saving the environment but saving on overall costs in the long run!
