Incorporating a strategy where the tenant purchases energy from the building owner's campus facility that produces renewable power to Green-e standards can contribute towards earning a LEED credit. This is because it supports the use of renewable energy, which is a key component of LEED's sustainable energy criteria.

The Water Efficiency Prerequisite for Indoor Water Use Reduction in LEED v4 ID+C requires a reduction in aggregate water use by 20% from the baseline.This includes all newly installed toilets, urinals, private lavatory faucets, and showerheads that are eligible for labeling, which must be WaterSense labeled or equivalent1. While pre-rinse spray valves and dishwashers are not explicitly mentioned, commercial kitchen pot filling faucets are considered as part of the water use reduction calculations.

LEED v4 water efficiency credits: Do you know the new standards?1.

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.

In a hot and dry location, incorporating evaporative cooling into the HVAC system is an effective strategy to minimize ozone depleting potential and global warming potential. Evaporative cooling is a process that uses the evaporation of water to cool air, using much less refrigerant compared to traditional air conditioning systems, which often contain ozone-depleting substances.This method not only reduces the use of harmful refrigerants but also consumes less energy, contributing to lower global warming potential1.

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 floor area. 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.

LEED rating system selection guidance2.

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.
