What is the allowed maximum tenant space exclusion for Energy and Atmosphere Prerequisite, Minimum Energy Performance?
The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 guide specifies that for the Energy and Atmosphere Prerequisite, Minimum Energy Performance, the allowed maximum tenant space exclusion is 10% of the gross floor area. This means that when calculating energy performance, up to 10% of the total floor area of the building can be excluded. This could be due to various reasons such as spaces being unoccupied or not in use.
The Energy and Atmosphere Prerequisite, Minimum Energy Performance, allows for certain exclusions to accommodate diverse building types and uses. One such provision permits the exclusion of up to 10% of the gross floor area (GFA) from the energy performance calculations. This allowance is designed to provide flexibility for spaces that may not be fully occupied or operational during the performance period, such as tenant spaces undergoing renovation or spaces with atypical energy usage. By excluding a limited portion of the GFA, the prerequisite acknowledges the variability in building occupancy and use, ensuring that the energy performance assessment is both fair and representative of the building's typical operations.
The allowance for excluding up to 10% of the gross floor area from the energy performance calculations is detailed in the LEED for Building Operations and Maintenance reference guide, specifically under the Energy and Atmosphere Prerequisite, Minimum Energy Performance. This guideline is part of the LEED AP O+M training materials, which emphasize the importance of accommodating diverse building uses and occupancy levels in the pursuit of sustainable building operations.
Which of the following strategies improves cooling tower water efficiency?
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.
When a building owner is deciding whether to execute an ASHRAE Level 2 audit or commissioning for Energy and Atmosphere Credit, Existing Building Commissioning -Analysis, which of the following statements most appropriately explains the difference between an ASHRAE Level 2 audit and commissioning of an existing building?
An ASHRAE Level 2 audit focuses on a detailed analysis of the building's energy systems and their operation against predefined sequences of operation to identify energy conservation opportunities. It includes a thorough review of building energy use and a site survey to identify potential energy-saving measures. Commissioning of an existing building, on the other hand, is a more comprehensive process that involves verifying and documenting that all of the building's systems perform interactively according to the owner's current operational needs and the building's design intent. It often includes system testing, calibration, and adjustments to ensure optimal performance. Reference: The distinction between an ASHRAE Level 2 audit and commissioning is detailed in the Energy and Atmosphere section of the LEED O+M Reference Guide, emphasizing the different objectives and scope of these activities.
When tracking waste data during the performance period for Materials and Resources Credit, Solid Waste Management - Ongoing, which strategy may be used to document total and diverted waste?
For the Materials and Resources Credit, Solid Waste Management - Ongoing, it is essential to accurately measure and document the amount of waste generated and diverted from landfills. This can be done by tracking the waste in terms of weight (pounds or kilograms) or volume (cubic yards or cubic meters). This method provides the most accurate accounting of waste management efforts and is a requirement for documenting performance for this credit. It allows for the calculation of diversion rates and effectiveness of waste reduction strategies.
The LEED for Building Operations and Maintenance Reference Guide details the requirements for waste tracking and documentation. This process is key to achieving the Solid Waste Management - Ongoing credit, which is aimed at reducing the amount of waste sent to landfills and incineration facilities, as emphasized in LEED AP O+M training materials.
