The WaterSense label, or a local equivalent, is required for all newly installed fittings and fixtures that are eligible for the label, as per the LEED v4 update.This label ensures that the fixtures used in a LEED building meet both water efficiency and high performance testing standards1.The WaterSense label is backed by independent, third-party certification and products bearing this label are verified to perform as well or better than their less efficient counterparts2.They are also certified to use at least 20 percent less water3.

The ENERGY STAR Portfolio Manager is a tool that helps measure and track the energy and water use, waste and materials, and greenhouse gas emissions of buildings. One of its features is that it requires the calculation and input of site energy usage.This is essential for assessing the whole building energy performance and tracking changes in energy over time12.

The Water Efficiency Prerequisite, Indoor Water Use Reduction, under LEED AP O+M V4.1, includes the reduction of water use in various indoor appliances. The appliances included in this prerequisite are those that contribute significantly to indoor water use. Among the options provided, residential clothes washers and dishwashers are included.These appliances use a significant amount of water and are therefore important targets for water use reduction1.

Installing and maintaining a conductivity meter is a strategy that improves cooling tower water efficiency. Conductivity meters help optimize the cycles of concentration, reducing water and chemical use by accurately measuring the water's mineral content.

Projects not eligible for the ENERGY STAR rating must demonstrate an energy efficiency of at least 25% better than the national average for typical buildings of similar type based on energy source. This can be done by using the ENERGY STAR Target Finder tool or a custom approved by USGBC.

For projects not eligible for the ENERGY STAR rating, an alternative path to demonstrate compliance with the Energy and Atmosphere Prerequisite, Minimum Energy Efficiency Performance, is to show that the building's energy efficiency is significantly higher than the baseline established for similar buildings. Demonstrating energy efficiency that is at least 25% better than the national average for comparable buildings, based on the type of energy used, provides a quantifiable metric that reflects the building's superior performance. This approach aligns with LEED's goal to encourage higher energy efficiency standards and reduce environmental impact through improved building performance.

This alternative compliance path for projects not eligible for ENERGY STAR rating is outlined in the LEED for Building Operations and Maintenance reference guide under the Energy and Atmosphere category. It provides a method for buildings to achieve the Minimum Energy Efficiency Performance prerequisite by exceeding the energy performance standards of similar buildings, promoting an advanced level of energy conservation in building operations as emphasized in LEED AP O+M training materials.

When retail project teams administer the supply chain survey to meet the requirements of the Materials and Resources, Ongoing Purchasing and Waste Policy, one of the key topics that needs to be addressed is environmental best practices for supply chain decisions. This involves assessing suppliers' environmental policies, practices, and impacts, with the aim of promoting sustainability throughout the supply chain. This approach encourages responsible sourcing, waste reduction, and the use of environmentally friendly materials. Reference: The Materials and Resources section of the LEED O+M Reference Guide includes guidelines for sustainable purchasing and waste policies, emphasizing the importance of considering environmental best practices in supply chain decisions.

This credit has exemplary performance because it allows projects to earn an additional point by reducing outdoor water use by 75% or more from the calculated baseline1. The credit requires projects to reduce outdoor water use by at least 50% from the calculated baseline, which is determined by the EPA WaterSense Water Budget Tool2. The credit encourages projects to use native or adapted plants, efficient irrigation systems, alternative water sources, or no irrigation at all.

When adding a new space within a facility to the ENERGY STAR Portfolio Manager, the required information includes the space floor area and hours of operation1.The tool helps building owners and tenants measure and track energy, water use, and waste, all in a secure online environment1.It is important to note that to receive an ENERGY STAR score in Portfolio Manager, you must enter 12 full calendar months of energy data for all energy types, in addition to complete data on property use details such as hours of operation and workers2.
