When green power is not Green-e certified, the project team can still pursue the Energy and Atmosphere Credit for Green Power by demonstrating that the purchased green power meets equivalent standards. This involves providing documentation that verifies the green power’s quality and production process align with the criteria set by Green-e certification.

References: The LEED v4 Reference Guide for Interior Design and Construction includes provisions for using green power that is not Green-e certified, as long as the project teamcan substantiate its equivalence. This can be done through third-party verification and ensuring that the energy source meets the requirements for renewable resources detailed in the current version of the Green-e standard123.

The Water Efficiency Prerequisite for Indoor Water Use Reduction in LEED aims to minimize water consumption within a building through efficient plumbing fixtures and fittings. The prerequisite encompasses a range of fixtures that significantly contribute to a building's overall water usage. Urinals and showerheads are standard fixtures addressed in this prerequisite, reflecting their common use in both commercial and residential settings and their potential for water savings. Commercial kitchen pot filling faucets are also included as they can have high flow rates and thus a significant impact on water use in settings where they are used. Toilets are also a critical component of water use calculations, but pre-rinse spray valves and dishwashers are more specifically addressed in other LEED credits focusing on process water use or the Energy and Atmosphere category due to their energy implications.References:

According to LEED requirements, the commissioning process is a critical part of verifying that building systems are installed and perform according to the owner’s project requirements, the basis of design, and construction documents. For a PV system installed after the initial commissioning, the commissioning agent (CxA) must return to conduct or oversee the additional commissioning activities to ensure the system is integrated properly and performs as intended123.

To comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance, the design must include mechanical outside air systems that meet the requirements of ASHRAE 62.1-2010. This standard specifies the minimum ventilation rates necessary to maintain indoor air quality. The project must document compliance by showing that the mechanical systems provide the appropriate amount of outdoor air to the occupied spaces.

References: The LEED v4 reference guide for Interior Design and Construction includes the Minimum Indoor Air Quality Performance prerequisite, which requires adherence toASHRAE 62.1-2010 for mechanical ventilation1. Additionally, the Minimum Indoor Air Quality Performance Calculator is a tool provided by USGBC for projects using ASHRAE 62.1 to comply with this prerequisite2.

The primary role of a LEED AP during the LEED certification process is to assist project team members in understanding the LEED rating system. A LEED AP possesses advanced knowledge in green building practices and expertise in a specific LEED rating system, which enables them to facilitate the project’s certification process by guiding the team through the requirements and credits of the LEED system1.

• Information about the role of LEED AP can be found in the LEED professional credentials section on the U.S. Green Building Council website1.
• Additional details on the responsibilities and benefits of being a LEED AP are available in resources provided by the Green Building Certification Institute and other green building education platforms23.

Renewable Energy Certificates (RECs) represent proof that energy has been generated from renewable sources. These certificates can be used by organizations to offset emissions from purchased electricity, which is considered scope two emissions. RECs are specifically designed for this purpose and are not applicable to non-electric energy use or electricity produced on-site.

References: This information aligns with the LEED v4 Reference Guide for Interior Design and Construction, which provides guidelines for achieving credits related to energy and atmosphere, including the use of RECs12.

For the LEED Location and Transportation Credit for Bicycle Facilities, providing at least one on-site shower and changing facility for employees is a minimum requirement to earn the credit. This is to encourage cycling as a mode of transportation by offering amenities that support cyclists1.

The WaterSense label, or a local equivalent, is a requirement for the Water Efficiency Prerequisite, Indoor Water Use Reduction in LEED v4 ID+C. This label ensures that eligible newly installed plumbing fixtures are both water-efficient and high-performing. The use of WaterSense labeled products is part of the strategy to reduce aggregate water use by 20% from the baseline12.

When a project’s installed water fixtures do not exceed WaterSense maximum levels, the appropriate compliance path under the Water Efficiency Prerequisite for Indoor Water Use Reduction is Compliance Path 1: Prescriptive Achievement. This path requires product cutsheets as documentation to demonstrate compliance. The product cutsheets serve as verification that the installed fixtures meet the WaterSense labeling requirements and do not exceed the maximum flow rates established by WaterSense standards.

References: The LEED v4 reference guide for Interior Design and Construction outlines the requirements for the Water Efficiency Prerequisite, Indoor Water Use Reduction, including the need for product cutsheets to document compliance with WaterSense maximum levels12.

 For projects aiming for prescriptive compliance with the Water Efficiency Prerequisite in LEED v4, public lavatory faucets must have a maximum flow rate of 0.4 gpm (1.5 lpm). This is in line with the LEED v4 Indoor Water Use Reduction Calculator and the LEEDuser’s guide, which provide the baseline requirements for various fixtures to meet the LEED certification standards12.

• LEEDuser’s guide on Commercial Interiors Water Efficiency Credit2.

In the context of LEED, particularly for projects pursuing prescriptive compliance for the Water Efficiency Prerequisite, the maximum flow rate for public lavatory faucets is set to encourage water conservation. A flow rate of 0.4 gallons per minute (gpm) or 1.5 liters per minute (lpm) is often the standard for these types of faucets in order to balance water efficiency with functional performance in public restrooms. This rate is sufficient for handwashing while significantly reducing water usage compared to higher flow rates. The decision to cap the flow rate at this level aligns with LEED's goals of reducing water consumption and promoting sustainable water management practices within buildings.References:

• LEED v4 for Building Design and Construction Reference Guide, specifically the section on Water Efficiency Prerequisite: Indoor Water Use Reduction

The Water Efficiency Prerequisite for Indoor Water Use Reduction in LEED AP ID+C V4 focuses on reducing the aggregate indoor water consumption by 20 percent from the baseline. This includes water usage by appliances such as residential clothes washers and dishwashers, which are common contributors to indoor water use.

References: The LEED v4 Indoor Water Use Reduction Calculator provides guidance on the baseline water consumption for various fittings and fixtures, including residential appliances1. Additionally, the LEED v4: Interior Design + Construction Guide outlines the requirements for achieving the prerequisite, emphasizing the reduction of indoor water use through efficient appliances2.

In the Water Efficiency Prerequisite for Indoor Water Use Reduction, the focus is on reducing potable water usage through efficient fixtures and appliances. The eligible appliances that fall under this prerequisite are residential clothes washers and dishwashers, as they are commonly used appliances within buildings and contribute to indoor water use. These appliances must meet certain efficiency standards, such as being ENERGY STAR certified or equivalent, which ensure they use less water than conventional models.
