USGBC LEED-AP-O+M Dumps

ASHRAE 55-2010 is the standard applicable for compliance with the Indoor Environmental Quality Credit, Thermal Comfort. This standard outlines the conditions for acceptable thermal environments and is used for the design, evaluation, and operation of buildings to meet thermal comfort requirements.

References: The LEED v4.1 O+M reference guide specifies that ASHRAE 55-2010 is the standard for thermal comfort, focusing on ensuring quality thermal environments conducive to occupants’ comfort and well-being1.

Increasing the treatment levels of potable makeup water is an allowable method to increase cooling tower cycles of concentration. This is because treating the makeup water can help control the buildup of minerals and other impurities, allowing the system to operate more cycles before requiring blowdown.

References: The LEED v4.1 O+M reference guide and other LEED resources emphasize the importance of water treatment to manage cycles of concentration in cooling towers.Proper treatment helps maintain water quality and efficiency, which is crucial for achieving higher cycles of concentration without causing scale and corrosion problems1.

The Water Efficiency Prerequisite for Indoor Water Use Reduction includes calculations for toilets, urinals, and pre-rinse spray valves. These fixtures are key contributors to water consumption within buildings and are therefore critical to achieving water efficiency.

References: The LEED v4 Indoor Water Use Reduction Calculator and the LEED v4.1 O+M reference materials provide guidance on the fixtures included in the water use reduction calculations1234.

For the calculations in the Water Efficiency Prerequisite Indoor Water Use Reduction in LEED, the plumbing fixtures that apply include toilets, urinals, and pre-rinse spray valves. These fixtures are critical components in reducing indoor water consumption and are therefore considered in the calculations for water efficiency and conservation.References:LEED v5 O+M: Existing Buildings beta version
