Pass LEED-AP-O+M Exam Guide

The correct answer is A because installing an on-site photovoltaic array is a strategy that is allowed under Energy and Atmosphere Credit, Renewable Energy and Carbon Offsets, and will help a project achieve Energy and Atmosphere Credit, Optimize Energy Performance, as stated in the LEED v4.1 O+M Reference Guide1.An on-site photovoltaic array can generate renewable energy for the project and reduce its greenhouse gas emissions and energy costs1. The other options are incorrect because they either do not helpthe project achieve Energy and Atmosphere Credit, Optimize Energy Performance, or are not allowed by the credit requirements.

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.

This answer is correct because it matches the requirement of the Energy and Atmosphere Credit, Optimize Energy Performance, which aims to reduce the environmental and economic impacts associated with excessive energy use. The credit requires projects todemonstrate an improvement in energy performance compared to a baseline building, using one of the three options available.For buildings eligible to receive an energy performance rating using the Environmental Protection Agency’s ENERGY STAR® Portfolio Manager tool, the option is to achieve a rating of at least 50, which corresponds to the median energy performance of similar buildings nationwide1. The other options are incorrect because they are either higher than the minimum rating or not applicable to this option.

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.
