LEED-AP-O+M Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

The Indoor Environmental Quality Prerequisite for Minimum Indoor Air Quality Performance has a minimum occupancy requirement to ensure that indoor air quality (IAQ) assessments accurately reflect the conditions experienced by building occupants. This prerequisite focuses on achieving acceptable IAQ within the building by meeting or exceeding local codes or ASHRAE standards, ensuring the health and well-being of the occupants.References:The LEED O+M Reference Guide's Indoor Environmental Quality section detailsthe requirements for maintaining minimum IAQ performance, including the importance of considering occupancy levels in IAQ assessments.

The correct answer is B because the transportation surveys must be distributed across all tenants proportionately, according to their populations, as stated in the LEED v4.1 O+M Reference Guide1. This ensures that the survey results are representative of the actual transportation patterns of the building occupants and avoids sampling bias. The other options are incorrect because they either do not account for the population size of each tenant or are not relevant for the survey distribution.

The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 focuses on improving the sustainability of existing buildings that are fully operational and have been occupied for at least a year12. Administering an alternative transportation survey is appropriate when the daily average or typical peak number of visitors is at least 50% of the regular building occupants. This is because the survey aims to understand and improve the transportation habits of a significant portion of the people interacting with the building, which includes both regular occupants and visitors. By focusing on this group, the LEED AP can identify opportunities to encourage alternative transportation modes, thereby reducing the building’s overall environmental impact.

The environmentally preferable purchasing policy (EPP) required in the Materials and Resources Prerequisite, Ongoing Purchasing and Waste Policy, should address the criteria in the Materials and Resource Credit: Purchasing - Facility Maintenance and Renovation. This policy ensures that the purchased products and materials for facility maintenance and renovation meet established environmental criteria, contributing to sustainable procurement practices in the building.References:LEED AP Operations + Maintenance Reference Guide, Materials and Resources section.

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.

• 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 Energyand Atmosphere and Water Efficiency categories. This metric is commonly used in sustainability projects to assess the viability of efficiency upgrades.

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.References: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 .

This credit has exemplary performance because it allows projects to earn an additional point by reducing outdoor water use by 75% or more from the calculated baseline1.The credit requires projects to reduce outdoor water use by at least 50% from the calculated baseline, which is determined by the EPA WaterSense Water Budget Tool2. The credit encourages projects to use native or adapted plants, efficient irrigation systems, alternative water sources, or no irrigation at all.

When retail project teams administer the supply chain survey to meet the requirements of the Materials and Resources, Ongoing Purchasing and Waste Policy, one of the key topics that needs to be addressed is environmental best practices for supply chain decisions. This involves assessing suppliers' environmental policies, practices, and impacts, with the aim of promoting sustainability throughout the supply chain. This approach encourages responsible sourcing, waste reduction, and the use of environmentally friendly materials.References:The Materials and Resources section of the LEED O+M Reference Guide includes guidelines for sustainable purchasing and waste policies, emphasizing the importance of considering environmental best practices in supply chain decisions.

To meet the requirements of the Materials and Resources Prerequisite for Facility Maintenance and Renovation Policy, an organization must include provisions to protect indoor air quality during renovation activities. This includes implementing dust control measures, ensuring proper ventilation, and minimizing the release of pollutants. These requirements are essential for protecting the health and safety of building occupants during renovation projects.References:The Materials and Resources section of the LEED O+M Reference Guide discusses the components of a comprehensive Facility Maintenance and Renovation Policy, including the importance of safeguarding air quality during construction and renovation activities.

For the Materials and Resources Credit, Purchasing - Facility Maintenance and Renovations, there is no specified minimum amount of renovation or new construction work required. The project team determines what qualifies for this credit based on the scope of their project.

References: The LEED v4.1 O+M reference guide does not specify a minimum renovation requirement for this credit, allowing the project team to define the scope of work that meets the intent of the credit1.
