When documenting compliance with Energy and Atmosphere Prerequisite, Minimum Energy Performance, for a manufacturing plant that is increasing units produced and the number of employees annually, it's crucial to use a normalization metric that accurately reflects the building's energy use in relation to its operational output. Relative production is the most suitable metric in this scenario as it accounts for the output or productivity level of the manufacturing plant, providing a fair and representative measure of energy performance as production scales.

Normalization against relative production allows for an equitable comparison of energy use as it adjusts for changes in production levels or operational intensity, ensuring that the energy performance metric reflects actual efficiency improvements or declines.

References:The approach to normalize energy use by relative production aligns with the guidelines and methodologies outlined in the LEED v4 and v4.1 for Building Operations and Maintenance (O+M) reference guide, specifically under the Energy and Atmosphere category. This document details how projects should account for variations in operational parameters that affect energy consumption to ensure accurate benchmarking and performance assessment.

For an office building with few visitors, the project team must survey the occupants to determine their transportation modes to comply with the Location and Transportation Credit, Alternative Transportation. This action is essential to understand and improve the transportation patterns of the regular building users.

References: The LEED v4.1 O+M guide outlines the requirements for the Alternative Transportation credit, which includes conducting surveys to gather data on the transportation habits of building occupants12.

This answer is correct because these are the two factors that affect the heat island reduction potential of the materials. The SRI is a measure of how well a material reflects solar radiation and stays cool in the sun. The higher the SRI, the lower the surface temperature and the less heat absorbed by the material. The unbound percentage of the open-grid pavement system is the ratio of the area that is not covered by the paving material to the total area of the system. The higher the unbound percentage, the more permeable the system and the more water infiltration and evaporation, which also reduce the surface temperature. The vegetated roof system does not need to have a specific SRI value, as long as it uses native or adapted plant species that provide shade and evapotranspiration. The open-grid pavement system does not need to have a specific SRI value, as long as it has at least 50% unbound area.
