For the Materials and Resources Credit, Purchasing - Facility Maintenance and Renovations, there is no specified minimum amount of renovation or new construction work required. The project team determines what qualifies for this credit based on the scope of their project.

References: The LEED v4.1 O+M reference guide does not specify a minimum renovation requirement for this credit, allowing the project team to define the scope of work that meets the intent of the credit1.

For a building that shares chilled water usage with other buildings on a campus, if the chilled water consumption is only measured at the campus level, additional meters would be required to comply with the Energy and Atmosphere Prerequisite for Building-Level Energy Metering. Individual metering at the building level is necessary to accurately track and manage the building's specific energy consumption, enabling targeted energy efficiency measures and compliance with LEED requirements.References:The Energy and Atmosphere section of the LEED O+M Reference Guide outlines the requirements for building-level energy metering, including the need for individual metering of significant energy uses such as chilled water in shared systems.

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 mercury content of the new T8 lamps remained the same; however, the average life of the bulb increasedJust Short Explanation: The decrease in the average picogram per lumen hour indicates an improvement in the environmental impact of the lamps. This can happen if the mercury content remains constant while the lifespan of the lamps increases, resulting in less mercury used over time per unit of light produced.

References: The information about T8 lamps indicates that newer models are designed to be energy-efficient with a longer lifespan while maintaining a low mercury content, which would contribute to a lower picogram per lumen hour ratio12.
