Achieving a minimum of 10 cooling tower cycles by increasing the level of make-up water treatment is the way to obtain the maximum number of points for Water Efficiency Credit, Cooling Tower Water Use. This credit aims to conserve water used for cooling tower equipment by encouraging the use of non-potable water sources and increasing the cycles of concentration1. The cycles of concentration are the ratio of the concentration of dissolved solids in the blowdown water to the concentration of dissolved solids in the make- up water2. Increasing the cycles of concentration reduces the amount of make-up water and blowdown water, and thus saves water and energy2. The credit has two options: Option 1. Non-potable Water Source (1 point) and Option 2. Cooling Tower Water Use (2 points). Option 1 requires using at least 50% non-potable water for cooling tower make-up water1. Option 2 requires achieving a minimum number of cooling tower cycles based on the quality of the make-up water, as specified in Table 1 of the credit requirements1. The maximum number of cycles is 10, which can be achieved by increasing the level of make-up water treatment to meet the criteria for conductivity, silica, and alkalinity1. Therefore, Option 2 is the way to obtain the maximum number of points for this credit. References:

Peak-hour is a term used to describe the time period when the traffic noise is highest, usually during morning and evening rush hours. Peak-hour noise level is measured by the equivalent continuous sound level (Leq), which is an energy-average of the noise level over a specified sample time. For minimum acoustic performance, LEED requires projects to implement acoustic treatment and other measures to minimize noise intrusion from exterior sources for high-noise sites (peak-hour Leq above 60 dBA during school hours).

The referenced standard for Indoor Environmental Quality (IEQ) Prerequisite: Minimum Indoor Air Quality (IAQ) Performance in LEED AP ID+C projects is ASHRAE 62.1 - 2010. ASHRAE 62.1 specifies ventilation rates and air quality requirements for acceptable indoor air quality in commercial buildings, establishing the minimum standards needed to maintain health and comfort. ASHRAE 62.2 (A) is relevant to low-rise residential buildings, ASHRAE 90.1 (B) covers energy standards, and ASHRAE 55 (C) relates to thermal comfort rather than air quality.

Detailed Explanation:
For the Surrounding Density and Diverse Uses credit, LEED requires project teams to calculate residential and non-residential densities within a 1/4-mile (0.40 km) radius of the project boundary. This measurement ensures that projects are located in areas with sufficient infrastructure and services to reduce dependency on vehicles and promote walkability.

Revise the documentation and resubmit the form
If a project receives a review comment and technical advice on a prerequisite, it means that the documentation submitted was incomplete, inaccurate, or unclear, and that the project team needs to address the issues raised by the reviewer and provide additional information or clarification. The project team should revise the documentation and resubmit the form as part of the final review to demonstrate compliance with the prerequisite requirements. Abandoning meeting this prerequisite is not an option, as prerequisites are mandatory for LEED certification. Submitting an appeal to Green Business Certification Inc. is only applicable if the project team disagrees with the reviewer's decision or interpretation, and has additional evidence or arguments to support their claim. Asking the General Contractor to be more aggressive with recycling goals is not relevant to this prerequisite, as it does not address the documentation issue.
