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.

In a scenario where the existing HVAC system was not designed to accommodate the required filters for Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2, Filtration, but is otherwise efficient and operating well, replacing the existing HVAC system with an air handler that can accommodate the filters is a strategy to achieve credit. This option allows for the integration of higher efficiency filters without compromising the performance of the HVAC system.

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.

LEED v4.1 O+M Reference Guide, p.1132: LEED v4 - U.S.Green Building 3: What is Blowdown Loss in Cooling

Cooling tower blowdown is a process used to manage water quality in cooling systems. It involves discharging a portion of the water from the system to control the concentration of dissolved solids and minerals, which accumulate due to the continuous evaporation of water. These dissolved solids can increase the water's conductivity, leading to scale formation, corrosion, and biofouling, all of which can significantly decrease the efficiency and lifespan of the cooling system. By performing blowdown, the system maintains the water quality within acceptable limits, ensuring optimal performance and energy efficiency of the cooling tower.

References:

• The need for cooling tower blowdown due to the accumulation of dissolved solids is discussed within the context of water management practices in cooling systems in the LEED AP O+M documentation. This process is crucial for maintaining system efficiency and is covered under the Water Efficiency category, emphasizing the importance of water management in achieving sustainable building operations.

Low Impact Development (LID) practices manage stormwater by using natural or man-made systems to filter and recharge stormwater into the ground12. A rain garden is an example of a LID technique for rainwater management3. It is a planted depression that allows rainwater runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas, to be absorbed. This reduces rain runoff by allowing stormwater to soak into the ground (as opposed to flowing into storm drains and surface waters which causes erosion, water pollution, flooding, and diminished groundwater).
