For the Water Efficiency Credit, Indoor Water Use Reduction calculations, all fixtures within the LEED project boundary must be included, both new and existing. The baseline for the existing fixtures should be the same as the baseline flush/flow rates used for the new fixtures. This approach ensures a consistent and fair comparison between the current and proposed water use.

When selecting a LEED Interior Design and Construction rating system, the LEED AP should use the rating system that is appropriate for the majority of the project’s gross floorarea. If more than 50% of the project’s area can be appropriately rated under a particular system, then that system should be applied to the entire project.

When determining the most applicable LEED Interior Design and Construction rating system for a mixed-use project, such as one consisting of both retail and office space, the general guideline is to choose the rating system that is appropriate for the majority of the project's gross floor area. If a specific LEED rating system covers more than 50% of the project's gross floor area, it should be selected for the entire project. This approach ensures that the chosen rating system aligns closely with the predominant use of the project, facilitating a more relevant and effective sustainability strategy that addresses the primary functions and needs of the space.References:

Reusing existing materials from another building, like the raised flooring in this case, contributes to the LEED goal of reducing the demand for virgin materials and minimizing environmental impact. This reuse can be considered as part of the Building Life Cycle Impact Reduction credit, which falls under the umbrella of Materials and Resources credits. Specifically, Option 3 of this credit deals with building and material reuse. By refurbishing and reinstalling an existing raised floor, the tenant's actions demonstrate leadership in extraction practices because they are extending the lifecycle of existing materials, thereby reducing the need for new materials and the environmental burden associated with material extraction and processing.

The use of plug-in devices can affect the Energy and Atmosphere Prerequisite, Minimum Energy Performance, as this prerequisite requires the establishment of a building’s energy performance that includes the energy consumption of all plug-in devices. These devices can significantly impact the overall energy usage and therefore influence the strategies to meet the minimum energy performance standards1.

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.
