(The project must be located in a region that offers this option) *Renewable energy certificates (RECs) can often be purchased even if the local utility does not offer renewable energy products. RECs aren't offered in all areas. *On-site renewable generation requires the purchase and installation of some sort of equipment that generates electricity. (Solar cells, wind turbines, steam turbine powered by burning biomass, fuel cells, or equipment that converts methane gas to electricity) *Off-site renewable energy is produced by equipment owned and operated by the utility company or its subsidiaries at a location other than the project site.

LEED for Core & Shell Development (LEED CS)- designed to complement the LEED for Commercial Interiors rating system (It covers core building elements such as structure, building envelope, and HVAC systems) LEED for Schools (LEED S)-used for certification of K-12 educational facilities and can also be used for prekindergarten or post-secondary buildings LEED for Healthcare (LEED HC)- used for inpatient, outpatient, and long-term care facilities LEED for Retail: New Construction (LEED R-NC)- adapted to the needs of the retail environment LEED for Commercial Interiors (LEED CI)- used for certification of tenant spaces in commercial and institutional buildings
LEED for Retail: Commercial Interiors (LEED R-CI)- interior retail spaces LEED for Existing Buildings: Operations & Maintenance (LEED EBO&M)- designed to encourage sustainable maintenance, cleaning, and operation of existing commercial structures. LEED for Homes (LEED H)- applies to single family homes and low-rise residential construction (fewer than 4 stories) LEED for Neighborhood Development (LEED ND)- emphasizes the elements of site selection, design, and construction that create vibrant, walkable, mixed-use neighborhoods What are the main advantages and disadvantages of using steel in building construction?
. - ANSWERS-Advantages: impervious to termites, added resistance to fire and earthquake, and they can span greater distances Disadvantages: conducts heat 300x faster than wood (they can create thermal bridges to the outside of the building) and by adding the additional insulation, it might reduce the cost-effectiveness. What are the seven credit categories of the LEED rating systems? . - ANSWERS-Sustainable Sites (SS) Water Efficiency (WE) Energy and Atmosphere (EA) Materials and Resources (MR) Indoor Environmental Quality (IEQ) Innovation in Design/Operations (ID or IO) Regional Priority (RP) What are the three components of the daylight that hits a work surface, and how can the balance of these components be enhanced? . - ANSWERS-The exterior reflected component The direct sun/sky component The internal reflected component Balance: a room with a higher ration of ceiling height to depth will have deeper penetration of daylight, whether that daylight enters through sidelighting (windows) or toplighting (skylights and clerestories). Raising the window head height will also result in deeper penetration and more illumination. A more even distribution can be achieved with horizontal strip windows.

A green rater? . - ANSWERS-Provider- In LEED for Homes, "an organization that recruits, trains and coordinates LEED for Homes Green Raters to serves as third-party verifiers of LEED homes. Providers are the official certifiers of LEED for Homes on behalf of USGBC." Green Rater- In LEED for Homes, "an individual that performs field inspections and performance testing of LEED for Homes measures for the LEED for Homes Provider. What is a TAG, and what is its role in the CIR process? . - ANSWERS-TAG- Technical Advisory Group The TAGs determine whether an action proposed by a project team fulfills the intent of the LEED credit requirements. The TAG chairs meet to debate the CIRs and finalize the rulings. What is a Trombe wall? . - ANSWERS-A trombe wall is a special type of masonry wall used for thermal storage in passive solar building. It consists of a masonry wall coated with a dark, heat- absorbing material and faces with a single or double layer of glass. HEat from sunlight passing through the glass is absorbed by the dark surface, stored in the wall, and conducted slowly inward through the masonry. What is characteristic of the design team when the whole-building design approach is being used? . - ANSWERS-It is essential that the design team be fully integrated from the projects's inception. What is distributed generation, and what are its advantages? . - ANSWERS-Distributed generation involves placing small, modular electricity generators close to where the power is used, which helps utilities defer or eliminate costly investments in transmission and distribution system upgrades while providing customers with better quality, more reliable energy supplies and a cleaner environment. What is LEED Online? . - ANSWERS-LEED Online is a repository for information and documentation gathered during the design and construction phases. The online tools can assist in performing
calculations, organizing the efforts of project team members, and summarizing the approaches that have been taken to earn points. What is the difference between post-consumer and pre-consumer recycled content? Give examples of each .
. - ANSWERS-Post-Consumer: Content that has already been used by a consumer (Example: water bottles that have been used) Pre-Consumer: Content diverted from the manufacturing process (Scraps from the manufacturing process of the water bottles) What is the Energy Star Portfolio Manager used for? . - ANSWERS-It allows facility managers to track and monitor energy and water consumption at all buildings in the company's portfolio. It can be used to evaluate building performance, set goals for improvement, or verify information for Energy Star building recognition. What is the heat island effect, and what are some strategies for reducing it? . - ANSWERS-Heat Island Effect: urban air and surface temperatures that are higher than nearby rural areas. Principal contributing factors include greater numbers of dark, non-reflective surfaces. Heat Island Effect reduction strategies: *Reduce the roof area by minimizing the building footprint *Plant trees for shade *Reduce or avoid the use of AC *Use less pavement (when needed, use paving that is at least 50% pervious) *Use paving and roofing materials with a high SRI value *Use a green roof or vegetated roof.
