• Minimum Energy Performance Prerequisite Information1.

The use of plug-in devices can have a significant impact on a building's energy profile, especially when considering the Indoor Environmental Quality Credit for Thermal Comfort within the LEED AP Interior Design + Construction framework. The Energy and Atmosphere Prerequisite, Minimum Energy Performance, is affected by the use of plug-in devices because these devices contribute to the building's overall energy consumption. This prerequisite requires projects to establish a minimum level of energy efficiency for the proposed building and systems. Plug-in devices can alter the thermal load and energy usage patterns within a space, thereby influencing the strategies employed to meet thermal comfort requirements. For instance, excessive use of personal heating or cooling devices might indicate inadequacies in the HVAC system's ability to provide comfortable conditions, which could affect the energy modeling and performance metrics required tocomply with this prerequisite. It's crucial for the design team to account for the energy impact of plug-in devices in their energy modeling and ensure that the building's systems can meet occupants' thermal comfort needs efficiently.

Best practices for ensuring that minimum program requirements (MPRs) for LEED certification are met involve confirming these requirements early in the project lifecycle. Specifically, this confirmation should occur during the discovery phase, which is the initial stage of a project. The discovery phase involves beginning initial research and analysis, and when sufficient information has been gathered, a goal-setting workshop is held to discuss findings. Part of these findings should include checking that the project complies with the MPRs for the applicable LEED rating system. Confirming MPRs during this early phase helps in setting a clear direction for the project and ensures that all subsequent work is aligned with LEED's fundamental requirements, facilitating a smoother certification process.

For the Materials and Resources Prerequisite, Storage and Collection of Recyclables, the project team must demonstrate that they can effectively manage and divert waste from landfills. Extending the waste stream study to a minimum of 24 hours will provide a more accurate representation of the waste generated and the recyclable streams. This is essential to identify the top five recyclable waste streams, which is a requirement for this prerequisite.

References: The LEED v4 reference guide for Interior Design and Construction specifies that a waste stream audit must cover a representative time period to accurately identify the project’s waste streams1. Additionally, the LEEDuser website provides guidance on how to conduct a waste stream audit and the importance of identifying the main types of recyclable waste1.

For LEED Indoor Environmental Quality Credit concerning Interior Lighting, Option 1, the requirement is for 90% of building occupants to have individual lighting controls. Given that the tenant space includes 100 workstations and 10 enclosed offices intended for individual use, this means that a total of 110 workspaces require lighting control. To achieve one point, at least 90% of these occupants must have control over the lighting in their space. Therefore, the minimum number of occupants that would need individual lightingcontrols is 90% of 110, which calculates to 99 occupants (rounded down). However, as individual controls cannot be split between occupants, the actual minimum number would be 99 occupants. Option B is the closest answer to 99 without going under the required percentage.
