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

For the Sustainable Sites Credit, Light Pollution Reduction, fixtures with a minimum of 1,500 lumens must be partially or fully shielded. This requirement helps to minimize light trespass and sky glow, contributing to the reduction of light pollution.

References: The LEED v4.1 O+M reference guide specifies the need for shielding on outdoor light fixtures to control light pollution.The threshold for lumens is set to ensure that lighting is designed to conserve the night sky1.

For the Sustainable Sites Credit, Light Pollution Reduction, outdoor light fixtures that directly emit light into the night sky and have a minimum lamp lumens exceeding 1,500 must be partially or fully shielded. This requirement is aimed at reducing light pollution by ensuring that outdoor lighting fixtures are designed and installed in a manner that minimizes sky glow and light trespass, thereby preserving the natural night environment.

The LEED applicant must exclude the purchases of the other tenants from the Materials and Resources credit calculations, because they have not provided purchasing data and are not participating in the LEED project. The LEED applicant can only include the purchases that are under their control and can be verified.

The maximum allowed performance period for LEED O+M re-certification is five years from the date that GBCI initially certified the building. This means that the project team must submit the re-certification application within five years of the initial certification date, or the certification will expire. The performance period is the time frame during which the project team collects and tracks data to demonstrate compliance with the LEED O+M requirements.

The use of electric-powered equipment is a sustainable management method that can be included in a project’s site management policy. It helps reduce emissions and pollution associated with gasoline-powered equipment, aligning with LEED’s environmental goals.

References: The LEED v4.1 O+M Guide and Site Management policy template provide guidance on sustainable site management practices, including the use of electric-powered equipment to minimize environmental impact123.

In developing a site management policy, one effective management method is to use electric-powered equipment instead of gasoline-powered equipment. Electric equipment typically produces fewer emissions and is quieter, contributing to a reduction in air pollution and noise pollution on the site. This practice aligns with LEED's emphasis on reducing environmental impacts and improving the quality of the site and surrounding areas.

References:The use of electric-powered equipment as a preferred management method is consistent with the guidelines provided in the LEED AP Operations + Maintenance reference materials, particularly in the context of developing sustainable site management policies. These resources advocate for practices that minimize environmental impact and enhance sustainability.

The correct answer is D because maintenance equipment is not a topic that is required to be addressed in the Site Improvement Plan for the Sustainable Sites Credit, as stated in the LEED v4.1 O+M Reference Guide1.The Site Improvement Plan must include topics such as soils, hydrology, vegetation, and site management, and describe the existing conditions, goals, strategies, and performance metrics for each topic1. The other options are incorrect because they are topics that are required to be addressed in the Site Improvement Plan.

In order to comply with the Sustainable Sites Credit, Site Improvement Plan, addressing the topics of soils, hydrology, and vegetation is essential. These elements are crucial for ensuring sustainable site management, enhancing site ecology, managing stormwater, and promoting biodiversity. However, the topic of maintenance equipment, while important for operational considerations, is not directly necessary for compliance with this specific credit. The focus of the Site Improvement Plan is on the physical and ecological aspects of the site rather than the equipment used for site maintenance.References:LEED v4 for Building Design and Construction Guide, U.S. Green BuildingCouncil.

The compliant value of green cleaning products and materials for LEED v4.1 O+M is calculated using the cost factor. This method allows for a consistent and monetary-based comparison of compliant products and materials.

References: The LEED v4 Green Cleaning Calculator provided by the U.S.Green Building Council is used to track and document purchases for LEED v4 O+M EQ Credits Green Cleaning - Products and Materials, which uses cost as the basis for calculations1.

For the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor both humidity and air temperature. These two factors are crucial for maintaining thermal comfort within the building environment.

References: The LEED v4.1 O+M reference materials specify the importance of monitoring humidity and air temperature as part of the requirements for achieving the Thermal Comfort credit12.

To achieve the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor at least two key factors: humidity and air temperature. These factors are critical for maintaining thermal comfort within a building, as they directly affect the perceived comfort levels of the occupants. Proper monitoring and management of humidity and air temperature ensure that the indoor environment remains within comfortable ranges for occupants, contributing to their well-being and productivity.

References:This requirement is specified in the LEED AP Operations + Maintenance reference guide within the section on Indoor Environmental Quality Credit, Thermal Comfort. The guide emphasizes the importance of maintaining optimal levels of humidity and air temperature for achieving thermal comfort in indoor spaces.

A new office building that has been LEED Gold certified and occupied for one month is immediately eligible to certify the building under LEED for Building Operations and Maintenance: Existing Buildings. The previous certification provides a baseline for sustainability performance, allowing the property manager to pursue further certification under the Operations and Maintenance category without any mandatory waiting period.References:LEED v5 O+M: Existing Buildings beta version

Using on-site captured rainwater and municipally treated wastewater for both flush fixtures and irrigation can be applied towards the credits for both Indoor Water Use Reduction and Outdoor Water Use Reduction in LEED. These alternative water sources contribute to the overall water efficiency of the project by reducing the reliance on potable water sources for indoor and outdoor uses.

This includes waste from commerce, trade, office buildings, institutions and small businesses. The other options are incorrect because they are either too high or too low compared to the actual data.

Commercial and institutional buildings are significant contributors to municipal waste generation. These buildings include offices, schools, retail stores, and healthcare facilities. Waste from these buildings comprises paper, cardboard, plastics, metals, glass, and organics, among other materials. The range of 35% to 45% accounts for the diverse activities within these buildings that generate waste, from daily operational waste to periodic large-scale waste from renovations and refurbishments. Waste management strategies in these buildings, such as recycling and composting programs, can significantly impact this percentage.References:LEED Reference Guide for Building Operations and Maintenance, U.S. Green Building Council.
