Green roof What is building density? Building density evaluates a building's total floor area as compared to the total area of the site and is measured in square feet per acre. What are the factors affect the amount of solar radiation that reaches a particular spot on earth The length of day The angle of sunlight on the ground Local landscape and weather The amount of atmosphere traversed by the sun radiation Increase impervious surfaces such as above ground parking should be minimalized. List the reasons. Impervious surfaces may increase storm water runoff. Impervious surfaces may contribute to the pollution in runoff water How is the earth's atmosphere heated? From the ground and objects that are warmed by solar radiation What are some factors regarding evaluating of a sustainable building site? Site Selection
Site design and management Transportation Stormwater management Transit Oriented Development is not just development near transit. What else is true regarding transit oriented development?

Ability of a material to give up heat in the form of long wave radiation How much are vehicles responsible for green house gas emissions? 20% from vehicles Which of the following is the best landscape design strategy to implement to reduce heat island effects? Increased albedo, or high SRI (Solar Reflective Index) At an individual building site, the effects of the sun's radiation and air temperature vary according to
Which of the following street grid density descriptions promotes a more pedestrian friendly community? A higher street grid density with narrow streets interconnecting On clear and dry nights, there is more night sky radiation, which allows the heat of the earth to radiate to the cool sky Which of the following are effective and sustainable strategies to address transportation for a green building project? Choose a site near a bus stop Limit parking Encourage carpooling What are some sustainable strategies for site design and management when designing a sustainable site? Reduce the size of a building's footprint Reduce light pollution Minimize water usage What are some good strategies for brownfield site remediation? Air sparing
Bio plugs Solar detox How many percent of energy use do buildings and transportation together account for in the United States? 70% What is the foundation for sustainable design for individual buildings or entire neighborhood? Location Which of the following is true regarding Brownfield Site remediation strategies Choose a remediation technique that minimizes the impact of cleanup on natural features Treat contaminants in place rather than off-site whenever possible Monitor the site after remediation to ensure that complete contaminant removal has occurred Developing a site that is a greenfield site disrupts the ecosystem by removing trees, native plants, animal habitats, and soil. In order to mitigate this ecological damage, how should sites be designed? Use native plant landscaping Minimize site grading What is floor-to-area ratio?
People living and working in outlying areas tend to drive greater distances, spend more time driving, own more cars, face a greater risk of traffic fatalities, and walk less. Which of the following types of properties is best suited for sustainable site development? Urban infill Graded site Half of the sunlight radiation is Visible solar wavelengths What are some negative aspects of heat island effect? Increase peak energy demand Increase air-conditioning cost Increase air pollution level What are some environmental benefits of using open grid paving with vegetated cells instead of black asphalt? Stormwater management Optimize energy performance
Which of the following is true regarding Solar Reflectance Index (SRI)? SRI is used to measure the amount of solar heat a surface can reflect What are some sustainable strategies than can be applied when selecting a site for new development? Increase building density Protect habitat Redevelopment and smart linkage Which of the following can be used to reduce stormwater runoff? Green roofs Pervious pavers Bioswales What material options would be best roofing materials for reducing heat island effect? White cement tile with an SRI of 90 What is true regarding Floor-to-area ration (FAR)? An increased FAR increases the density and therefore increases the open space A reduced FAR reduces the density and therefore reduces the open space.
Which one of the following is correct regarding Northern Hemisphere: The sun rises in the south-east and sets in the south-west in the winter What are some steps developers should take when they are considering using brownfield site for development? Determine the appropriate and feasible level of cleanup, and find out whether there are federal, state, or local requirements for cleanup Evaluate how long the cleanup will take, how much it will cost, and the effects of the cleanup Evaluate community concerns about the impact on resident's health during cleanup and reuse of the site What type of assessment is used to determine brownfield sites? ASTM E1903-97 Phase II environmental Site Assessment What are some sustainable strategies for stormwater management? Increase pervious surface Reduce stormwater runoff by using rain gardens, bioswales, wet or dry ponds Harvest rain water Xeriscaping A landscape design that requires little or no irrigation or no maintenance
Eutrophication A reduction in overall water quality due to an increase in the concentration of chemical nutrients Which of the following can be considered as sustainable strategies for indoor water use? Use efficient plumbing Install submeters to track consumption and monitor leakage Use nonpotable water for flush functions for toilets and urinals Which of the following strategies might contribute to water efficient landscaping? Planting of hardwood trees to provide shades Planting of native or adapted plant species Combining vegetated swales and cisterns to capture rainwater What are some sustainable strategies to increase process water efficiency? Use efficient equipment and appliances such as boilers, chillers, and cooling towers Use nonpotable water for process water, such as captured rainwater, graywater, and municipal reclaimed water Install submeters to track consumption and monitor for leakage Which of the following water source must be contained and treated before it may be used to irrigate landscaping?
Bottle water extraction and distribution uses more energy and has other environmental impacts How does water efficiency help to reduce building energy consumption and therefore building operation costs? By reducing the amount of water that must be treated, heated, cooled, and distributed. If an existing building seeks water efficiency strategies but has a limited budget, installing which of the following would be economically viable options? Aerators Flush valves Can more water consumption use more energy and in turn cause more pollution? Yes What is an infiltration system? A swale that is designed to capture rainwater and allow it to percolate into the ground to the groundwater aquifer A surface retention basin that is designed to capture rainwater above the ground. An underground storage system consisting of perforated pipes and tanks with gravel backfill that allow stored water to escape and soak into the ground What can be counted as greywater?

Municipally supplied reclaimed water Captured rainwater Graywater What is the water consumption rate of a conventional urinal? 1 gpf Which one of the following is a flow fixure? Kitchen faucet Showerhead How is the water consumption measured in a flush fixture?
Where does most of the water from a building go after we are done with it? Sewage treatment plants What is the largest use of household water? Flushing toilets If I live on hill, can water get to my house from a public water supplier? Yes, through pumps How many gallons of water does a conventional water closet use per flush 1.6 gpf Wastewater factor 80% or 0. Faucet water usage 0.5 gallons per minute (gpm)
