9LEED Rating SystemsThese are the different LEED tools that exist at the moment or are in development. Mention that the LEED letter templates and LEED calculators are tools you can use to demonstrate compliance with the LEED rating system. As not every building can fit into the basic guidelines set by the LEED rating system, addendums are being developed to include those different sectors of the built environment. Here are the basics:LEED for new construction (or major renovation): for building owners and design teams that address the new building design and construction or major renovations process. Also referred to as LEED 2.0 or LEED 2.1LEED-EB: set of performance standards for the sustainable operation of existing buildings. The LEED-EB criteria cover building operations and systems upgrades in existing buildings where the majority of interior or exterior surfaces remain unchanged.LEED-CI: addresses the specifics of tenant spaces in office, retail, and institutional buildings.LEED-CS: Broadly defined, core and shell construction covers base building elements, such as the structure, envelope and building-level systems, such as central HVAC, etc. The CS product recognizes that the division between owner and tenant responsibility for certain elements of the building varies between markets. CS is used for buildings where the owner does not control interior design and fit-out.LEED-H:These are the different LEED programs that exist or are in development:LEED-NC: For building owners and design teams that address the new building design and construction or major renovations process.LEED-EB: Set of performance standards for the sustainable operation of existing buildings.

The program is applicable for commercial, institutional, and high-rise residential buildings. Major renovation is defined as major HVAC renovation, significant envelope modifications, and major interior rehabilitation. There are seven prerequisites and 26 points that must be fulfilled in order to be a part of the program and achieve LEED Certification. A project can achieve more optional points to get a higher Certification, and a higher performance building.
11LEED-NC Point Distribution Credit FormatEach credit identifies:IntentRequirementsTechnologies & StrategiesSustainable Sites: 14 ptsWater Efficiency: 5 ptsEnergy & Atmosphere: 17 ptsMaterials & Resources: 13 ptsIEQ: ptsInnovation & Design: 5 ptsTOTAL: 69 PtsWithin LEED New Construction and Major Renovation, energy makes up the most points, though other aspects that create a sustainable building are very important. Understanding the major components of the Rating System and what they encompass is important for passing the test. Each credit has an intent, requirements, technologies and strategies, as well as the submittal documents necessary to achieve points.
12Sustainable Sites Develop appropriate sites Use existing infrastructurePreserve natural areasReduce need for automobilesProtect endangered habitatsRestore polluted sites
13Water EfficiencyIn the U.S., about 340 billion gallons of fresh water are withdrawn daily from rivers, streams, & reservoirsWater treatment is municipality’s single biggest energy bill (water savings = energy savings)Power plants consume 3 gallons of water per kWh produced (energy savings = water savings)Explore Innovation points with non-regulated (process) water or exemplary performanceSouthern States Energy Board 3 gallons / kWh
14Energy & Atmosphere 17 possible points Buildings consume ~40% of U.S. energy (70% of electricity)Fossil fuels produce 3/4 of our energyCoal power plants emit more fine particulate material than any other U.S. activityNatural gas (CO2), nuclear energy (radiation), and hydroelectric power (habitat disturbance) all have negative impacts on ecological systemsEfficient buildings reduce pollution & cost and enhance comfort17 possible points
15Materials & ResourcesConstruction/Demolition waste makes up 40% of U.S. wasteReuse/Recycling saves production & transportation energy & landfill roomSalvaged/Recycled content materials minimize the use of finite, declining resourcesRapidly Renewable resources minimize impact of natural resource consumption for manufacturingDo not print hidden slides!
16Indoor Environmental Quality Americans spend 90% of their time indoorsInside pollutant levels may be 2 to 5 times higher than outdoor levels17 million Americans have asthma and 40 million suffer from allergiesBetter IEQ can improve worker productivity more than 15%15 possible points

The rating system is a condensed version of the guide that is a free downloadable .pdf file from the website which contains a credit checklist, followed by a brief summary for each credit criteria, including intent, requirements, and potential technologies and strategies.
