--Question 1: Water Efficiency What landscaping strategy will best eliminate the need for irrigation? A. Micro-irrigation B. Mulching C. Xeriscaping D. Drip irrigation C is the correct answer. Xeriscaping is a landscaping method that employs drought-resistant plants to minimize or eliminate water use. --Question 2: Sustainable Sites Which of the following does a site assessment evaluate? A. Existing structures and Surrounding density B. Hydrology and Shading C. Hydrology and Geology D. Shading and Existing structures E. Surrounding density and Existing structures C is the correct answer. A site assessment is "an evaluation of an area's above ground and subsurface characteristics, including its structures, geology, and hydrology. Site assessments typically help determine whether contamination has occurred and the extent and concentration of any release of pollutants. Remediation decisions rely on information generated during site assessments." – USGBC --Question 3: Location and Transportation What is the impact of creating a dense, compact mixed-use neighborhood? A. Less pavement for roads and less infrastructure for utilities B. Increased in the travel time to work for occupants C. Increased in flooding from stormwater runoff and the heat island effect D. Decreased availability of alternative transportation A is the correct answer. If buildings are closer together and hold more occupants, less roads and utility infrastructure is required. This saves on materials which reduces demand for virgin materials and transportation of those materials.

--Question 10: Water Efficiency Which of the following would a landscape architect use to measure the outdoor water use of a project? A. EPA WaterSense Water Budget Tool B. Local historic records C. IPC and UPC codes D. EPAct 1992 A is the correct answer. The WaterSense Water Budget Tool is a free online tool to help calculate the percent of outdoor water use reduction in LEED. A water budget is a site-specific method of calculating an allowable amount of water to be used by the landscape and then designing the landscape to meet this budget. The budget considers plant type, plant water needs, irrigation system design, and applied water that the landscape receives either by irrigation or by precipitation. Water budgets must be associated with a specified amount of time, such as a week, month, or year. --Question 11: Indoor Environmental Quality What is the best design strategy for improving indoor air quality during operations and maintenance of a building? A. Use air filters with high Minimum Efficiency Reporting Value (MERV) ratings B. Orient the building for optimal sun exposure C. Use natural refrigerants D. Use soft surfaces on the interiors A is the correct answer. Minimum Efficiency Reporting Value (MERV) ratings are a standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient) and measures a filter's ability remove particles from 3 to 10 microns in size. The ratings were developed by ASHRAE. --Question 12: LEED Process What does LEED stand for? A. Leadership in Energy Efficient Design B. Leadership in Energy and Environmental Design C. Leadership in Energy and Efficient Design D. Leadership in Environmental Efficient Design B is the correct answer. Leadership in Energy and Environmental Design.

--Question 13: Sustainable Sites The Sustainable Sites category focuses on all the following EXCEPT which of the following: A. Restoring project site elements B. Integrating the site with local and regional ecosystems C. Preserving the biodiversity on which natural systems rely D. The ways in which community infrastructure affects occupants' behavior and environmental performance. D is the correct answer. This choice is the focus of the Location and Transportation category. --Question 14: Energy and Atmosphere What is lighting power density measured in? A. Number of luminaries per unit area B. Installed lighting power per unit area C. Footcandles per floor area D. The quantity of light trespass on adjacent sites, measured in watts B is the correct answer. Lighting power density is the installed lighting power per unit area (the amount of electrical power used to illuminate a space). It is usually expressed in Watts per unit of area. Reducing the lighting power density can reduce energy use. --Question 15: Indoor Environmental Quality Which of the following preventive maintenance tasks would a facility manager routinely perform to maintain indoor air quality? A. Conducting a flush-out and Replacing air filters B. Calibrating sensors and Replacing air filters C. Conducting a flush-out and Cleaning the ducts with UV light D. Dusting all blinds with electrostatic cloths and Calibrating sensors B is the correct answer. Checking the CO2 sensors and the outdoor airflow monitors are tasks the facilities manager could do periodically to make sure the system is functioning as designed. Replacing air filters should be done as part of a routine preventive maintenance schedule.

--Question 16: Materials and Resources Which of the following does NOT exemplify strategies of reducing harm to the environment over a building's entire life? A. Restoring a historic building B. Using salvaged flooring in a new building C. Conducting a life-cycle assessment to help reduce a building's environmental footprint D. Tearing down a building and putting up a more energy-efficient one in its place D is the correct answer. Studies show that most of the time an existing building can be renovated/reused and achieve the same energy savings as a new building would have, without demolishing and sending the old building to the landfill. --Question 17: Sustainable Sites A bioswale would be used to help earn credit in what LEED category? A. Water Efficiency B. Energy and Atmosphere C. Sustainable Sites D. Indoor Environmental Quality C is the correct answer. Bioswales are landscape elements designed to remove silt and pollution from surface runoff water during and after construction. They consist of a swaled drainage course with gently sloped sides and filled with vegetation, compost and/or riprap. Bioswales would be used to help capture and improve the quality of runoff. --Question 18: Water Efficiency If a project owner wants to create a landscape with plants that require watering, which of the following is the minimum outdoor water reduction from a baseline required for a new office project? A. 10% B. 20% C. 30% D. 40% C is the correct answer. 30%.
