QUESTION: 13

When tracking waste data during the performance period for Materials and Resources Credit, Solid Waste Management - Ongoing, which strategy may be used to document total and diverted waste?

Measure and document waste in weight or volume
Use replacement value as the metric for ongoing waste
Extrapolate data from one month of the performance period
Do not allow tenant waste outside the building's waste program to be included

Answer(s): A

Explanation:

For the Materials and Resources Credit, Solid Waste Management - Ongoing, it is essential to accurately measure and document the amount of waste generated and diverted from landfills. This can be done by tracking the waste in terms of weight (pounds or kilograms) or volume (cubic yards or cubic meters). This method provides the most accurate accounting of waste management efforts and is a requirement for documenting performance for this credit. It allows for the calculation of diversion rates and effectiveness of waste reduction strategies.

Reference:

The LEED for Building Operations and Maintenance Reference Guide details the requirements for waste tracking and documentation. This process is key to achieving the Solid Waste Management - Ongoing credit, which is aimed at reducing the amount of waste sent to landfills and incineration facilities, as emphasized in LEED AP O+M training materials.

QUESTION: 14

Which of the following is the most appropriate use of untreated stormwater?

Irrigation
Boiler water makeup
Drinking fountain
Cooling water makeup

Answer(s): A

Explanation:

Untreated stormwater, due to its potential contaminants, is not suitable for potable uses but can be effectively utilized for non-potable applications such as irrigation. It provides a viable alternative to using treated water for landscape irrigation, thereby conserving potable water resources. This use aligns with sustainable water management practices encouraged by LEED, which promote the reduction of potable water usage for landscape irrigation.

Reference:

The LEED Reference Guide for Green Building Design and Construction and the LEED O+M Reference Guide both encourage the use of untreated stormwater for irrigation as part of an integrated water management approach. This conservation strategy is covered under the Water Efficiency category and is a common topic in LEED AP O+M training sessions.

QUESTION: 15

An equipment upgrade requires an initial investment of $1,500.00 USD with a total annual savings of $500.00 and a 33% rate of return.
What is the Simple Payback Period for this improvement?

120 days
495 days
Two years
Three years

Answer(s): C

Explanation:

The Simple Payback Period is the time it takes for an investment to pay for itself through savings. To calculate the Simple Payback Period, divide the initial investment by the annual savings. In this case, $1,500.00 USD divided by $500.00 equals 3. To find the exact payback period, consider the rate of return. With a 33% rate of return, the actual savings per year would be $500.00 plus 33% of $500.00, which equals $665.00. Dividing the initial investment of $1,500.00 by $665.00 gives a payback period of approximately 2.26 years, which is closest to two years.

Reference:

The concept of Simple Payback Period is a fundamental financial calculation discussed in the LEED AP O+M documentation. It is part of evaluating the cost-effectiveness of energy and water efficiency improvements, particularly under the Energy and Atmosphere and Water Efficiency categories. This metric is commonly used in sustainability projects to assess the viability of efficiency upgrades.

QUESTION: 16

A 1,500 ft2 (139 m2) mobile home is built in the downtown area of a major city. 90% of the project's gross floor will be completed by the time of occupancy. LEED certification is being sought.
Which rating system would be the most appropriate one to use?

LEED Interior Design and Construction
LEED Building Design and Construction
LEED for Homes
No rating system

Answer(s): C

Explanation:

For a mobile home, especially one built in a major city, the most appropriate LEED rating system to use would be LEED for Homes. This is because ASHRAE 90.1 and associated LEED rating systems typically exclude low-rise residential buildings, which include single-family houses, multifamily structures of three stories or fewer above grade, and manufactured houses (modular or mobile homes). Since the mobile home in question falls under the category of manufactured houses, it would be more fitting to pursue LEED for Homes certification, which is designed to cater to residential projects.

Reference:

Information derived from the ASHRAE 90.1-2013 User's Manual indicates the exclusion of low-rise residential buildings, including manufactured houses, from the standard's scope .
