LEED Certification
The Reason Why…
It is quite imperative that we as Americans decrease our fossil fuel consumption in efforts to sustain our beautiful world. Many elements of the Earth are being stripped away and not replaced or renewed, which can lead to significant negative effects on our environment.
Many negative effects on the environment are due to greenhouse gas emissions which pollute our atmospheres and result in the production of acid rain.
Efforts to mitigate the human footprint have led to important developments in sustainable building design and construction.
Green buildings are more efficient and employ a variety of both construction techniques and renewable materials that contribute to less environmental harm and an increase in energy efficiency.
According to the USGBC website:
Past research has focused on the impact of green design and construction on the health and productivity of the final occupants of a facility.
Literature indicates that green building concepts, applied to the design, construction and operation of buildings, can enhance both the economic well-being and environmental health of a buildings final occupants.
There are several Green Building initiatives and programs but above all, the United States Green Building Council (USGBC) is the country’s largest and most well-known.
The USGBC created LEED-Certification as a way to rate green buildings as well as encourage project managers to become certified and receive several benefits from doing so.
What is USGBC?
The USGBC is the United States Green Building Council and its purpose is to promote a prosperous and sustainable future for our nation through the construction of cost-efficient and energy-saving green buildings.
Their Mission: To transform the way buildings and communities are designed, built and operated, enabling an environmentally and socially responsible, health, and prosperous environment that improves the quality of life.
Their Vision: Buildings and communities will regenerate and sustain the health and vitality of all life within a generation.
What does the USGBC comprise of?
The USGBC is comprised of 78 local affiliates, more than 18,000 member companies and organizations, and more than 140,000 LEED Professional Credential holders.
The organization is projected to contribute nearly $554 billion to the U.S. gross domestic product from 2009-2013.
USGBC Programs
USGBC Programs include:
LEED Green Building Certification
The USGBC’s preeminent green building certification rating system.

What is LEED?
LEED stands for Leadership in Energy and Environmental Design.
LEED is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies intended to improve performance in metrics such as energy saving, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
Why Build Green?
According to the USGBC website –
Buildings in the United States are responsible for:
Greater building efficiency can meet 85% of future U.S. demand for energy and the potential to generate 2.5 million American jobs.
It is important that all consumers understand the statistics surrounding our nation’s carbon footprint in reference to energy and water consumption.
There are simple ways for our nation to be proactive about the reduction of the usage of fossil fuels. LEED buildings provide several benefits regarding sustaining an environmentally-friendly architectural building.
Many benefits besides a step towards environmental sustainability, include an overall decrease in energy costs per year, an overall decrease in water costs per year and an achieved mindset among the community and one’s self that the earth is a main priority to be addressed by all.
By using less energy, LEED-certified buildings:
-
Save money for families, businesses, and tax-payers.
-
Reduce greenhouse gas emissions.
-
Contributes to a healthier environment for residents, workers and the community
LEED Green Building Rating Systems
The LEED green building certification system is the preeminent program for rating the design, construction, and operation of green buildings. 35,000 projects are currently participating in the LEED system, comprising over 4.5 billion square feet of construction space in all 50 states and 91 countries.
LEED is a voluntary certification program that can be applied to any building type and any building lifecycle phase.
It is important for the LEED Rating Systems to serve all types of architecture and community buildings so that everyone can be included in the efforts to become a sustainable nation. As you can see below, there are 9 different areas in which LEED certification can be issued.
LEED Version 3
LEED V3 was launched on April 27, 2009 and it is the latest system of green building certification. LEED V3 builds on the fundamental structure and familiarity of the existing rating system, but provides a new structure for making sure the rating system incorporates new technology and addresses the most urgent priorities.
LEED V3 consists of 3 components:
-
LEED 2009: technical advancements to the LEED rating systems’ credits and points.
-
LEED Online: an upgrade to LEED Online that is faster and easier to use.
-
New Building certification model: an expanded certification infrastructure based on ISO standards, administered by the Green Building Certification Institute (GBCI) for improved capacity, speed and performance.
LEED-Certified Buildings are designed to:
-
Lower operating costs and increase asset value
-
Reduce waste sent to landfills
-
Conserve energy and water
-
Be healthier and safer for occupants
-
Reduce harmful greenhouse gas emissions
-
Qualify for tax rebates, zoning allowances and other incentives in hundreds of cities
-
Demonstrate an owner’s commitment to environmental stewardship and social responsibility
The following are the LEED Rating Systems:
Basically, the certification system is in the form of a checklist, in which points are rewarded, that reflects the potential of the structure as well as the environmental impact that it will achieve overall.
LEED points (credits) are awarded on a 100-point scale and credits are weighted to reflect their potential environmental impacts.
Additionally, 10 bonus credits are available, four of which address regionally specific environmental issues (Regional Priority). A project must satisfy all prerequisites and earn a minimum number of points to be certified.
The program envelops the growing efforts of sustainability by recognizing 9 key areas:
-
Sustainable Sites
-
Water Efficiency
-
Energy & Atmosphere
-
Materials & Resources
-
Indoor Environmental Quality
-
Locations & Linkages
-
Awareness & Education
-
Innovation in Design
-
Regional Priority
For a better understanding, each of the key areas will be discussed in detail within the following:
Sustainable Sites
The Sustainable Sites category is broken down into the following several functions:
-
Discourages development on previously undeveloped land
-
Minimizes a building’s impact on ecosystems and waterways
-
Encourages regionally appropriate landscaping
-
Rewards smart transportation choices
-
Controls storm-water runoff
-
Reduces erosion, light pollution, heat island effect, and construction-related pollution.
Water Efficiency
Due to the fact that large buildings are major users of our potable water supply, it is crucial to incorporate water efficiency as a main focus when designing a LEED Certified building.
Water reduction is typically achieved through more efficient appliances, fixtures, fittings inside of the building and water-wise landscaping outside including rainwater harvesting, green roofs, incorporation of native plants, etc.
The Water Efficiency category is very important because it encourages smarter use of water, both inside and outside of the building. This proactive mindset will hopefully be recognized and passed on; and consequently, water-sustaining habits will then be seen within a person’s daily life.
Energy & Atmosphere
The Energy & Atmosphere category addresses and encourages the following energy-saving strategies:
-
Commissioning
-
Energy use monitoring
-
Efficient design and construction
-
Efficient appliances
-
Systems & lighting
-
The use of renewable and clean sources of energy, generated on-site or off-site
Energy is a crucial factor to take into consideration when designing GREEN plans for building, renovation and demolition. Energy consumption is extremely high within the United States and this particular LEED certification category rigorously rates the efficiency of a building’s energy use.
It is very important for buildings to be tested for the amount of energy consumption that they acquire in order to establish a clear rating of the building within this category.
A great deal of time should be spent choosing the correct energy-efficient appliances and systems for the home if you are looking to decrease costs associated with energy and utility bills.
Materials & Resources
The Materials and Resources category encourages the selections of sustainably grown, harvested, produced and transported products and materials.
It promotes the reductions of waste as well as reuse and recycling, and takes into account the reduction of waste at a product’s source.
This particular category includes several different areas of recycling and sustainable waste management. Sustainable waste management is very important within our nation because the amount of waste being produced is too much for our designated landfills to hold and as a result cause varying amounts of pollution and harm to the environment.
It is also important to purchase materials that are sustainably made or acquired because after all, you are looking to build a LEED certified sustainable building and to be passive with the materials used to do so is only a step back in the race for environmental change.
Indoor Environmental Quality
Indoor air quality can be significantly worse than the quality of the air outside and most people spend their entire day indoors. This raises a pertinent concern that the indoor environmental quality of one’s home, school, and job may have negative consequences.
The Indoor Environmental Quality category promotes strategies that can improve indoor air quality as well as providing access to natural sun-light and views and improving the acoustics of the area or building.
Locations & Linkage
The Locations & Linkages category promotes that homes be built away from environmentally sensitive places and instead encourages homes to be built in infill, previously developed and other preferable sites.
The rating system rewards homes that are built near:
And encourages:
Awareness & Education
The Awareness & Education category encourages home builders and real estate professionals to provide homeowners, tenants and building managers with the education and tools that they need to understand what makes their home green and how to make the most of those features.
It is important to understand Green Building and LEED Certification in order to successfully take advantage of the many qualities provided by the building, inside and out.
Innovation in Design
The Innovation in Design category provides bonus points to projects that use new and innovative technologies and strategies to improve a building’s performance that exceeds the requirements of Green Building or LEED Certification.
It rewards projects for including a LEED Accredited Professional on the team to ensure a holistic, integrated approach during the design and construction phase.
It is important to have this particular category because it provides another reason to be innovative and use creative designs that can potentially advance the green movement.
Regional Priority
Dependent upon the state, up to four extra credits can be earned by any project that earns a regional priority credit.
Meaning, that depending on the state where the location or building in question resides, credits will be given in the situation when the construction of the building will greatly improve the quality of life in the surrounding communities.
LEED RATING
LEED rating is simplified into four levels of accomplishment in the nine key areas stated above. Those levels are:
- Certified
- Silver
- Gold
- Platinum
The USGBC website lists 9,812 projects that have been LEED certified and nearly half of the projects were homes.
-
Certified: 663 projects -- 779 homes
-
Silver: 2215 projects -- 4071 homes
-
Gold: 1001 projects -- 2770 homes
-
Platinum: 694 projects -- 2192 homes
The following chart shows the comparison between the numbers of LEED certified projects and LEED certified homes.

As you can see, designing homes that promote sustainability is an emerging phenomenon within our society that should be praised and more homes should become sustainable, if not physically, then at least by the family inside of the home.
