LEED-AP-O+M Exam Dumps : LEED AP Operations + Maintenance (LEED AP O+M)

According to the LEED v4.1 Building Operations + Maintenance Guide, for a campus project using a Group Approach to comply with the Water Efficiency Prerequisite, Building-Level Water Metering, it is necessary to meter water use for all buildings aggregately with a single meter and also meter outdoor water use for the associated grounds1.

The LEED AP O+M Reference Guide states that “If a meter fails during the performanceperiod, the project team must extend the performance period to obtain the required three months of data.” Therefore, the best advice is to extend the performance period to gain the full three months of weekly water meter readings.

For compliance with the Sustainable Sites Credit, Site Management, when submetering of the irrigation system is not available or difficult to implement for an existing building, the recommended strategy is to use automated leak detection systems, such as those that use pressure sensors. The guidance for irrigation management under the LEED for Operations and Maintenance (O+M) rating system includes monitoring irrigation systems manually or with automated systems at least every two weeks during the operating season for appropriate water usage, system times, leaks, or breaks. Automated systems, particularly those employing pressure sensors, are effective in detecting leaks and irregularities in water use,thereby contributing to efficient water management and maintenance of the irrigation system.References:LEED v5 O+M: Existing Buildings beta version
