When using the Integrative Process, the best way for the LEED AP to assess the impact of indoor and outdoor water consumption in a Building Design and Construction projectis to perform a preliminary water budget analysis before the completion of schematic design.This analysis should include the following steps1:

• Identify the project’s water sources and uses, such as potable water, reclaimed water, rainwater, graywater, blackwater, irrigation, cooling towers, etc.
• Estimate the baseline water consumption for each use based on the applicable codes, standards, and benchmarks.
• Identify potential water conservation strategies that can reduce the demand or increase the supply of water, such as low-flow fixtures, native landscaping, rainwater harvesting, graywater reuse, etc.
• Evaluate the feasibility, cost-effectiveness, and environmental benefits of each strategy using a life-cycle approach.
• Select the most appropriate strategies and document how they inform the design decisions and meet the project goals.
• Compare the projected water consumption with the baseline and calculate the percentage reduction.

Performing a preliminary water budget analysis before the completion of schematic design allows the LEED AP to identify opportunities for water efficiency and innovation early in the design process. It also helps to optimize the integration of water systems with other building and site systems, such as energy, materials, indoor environmental quality, etc.Moreover, it supports the achievement of other LEED credits related to water efficiency, such as WE Prerequisite 1: Outdoor Water Use Reduction, WE Prerequisite 2: Indoor Water Use Reduction, WE Credit 1: Outdoor Water Use Reduction, WE Credit 2: Indoor Water Use Reduction, WE Credit 3: Cooling Tower Water Use2.

According to the LEED v4: Building Design + Construction Guide, the document that allows a LEED AP to register a project and sign the Certification Agreement is the Owner Confirmation of Agent Authority. This form is used to validate the Certification Agreement when it is signed by someone other than the owner, such as a LEED AP.It provides proof that the owner accepts the conditions in the Certification Agreement and authorizes the LEED AP to act as the owner’s agent for the purpose of LEED project certification1.The other choices are not relevant documents for this purpose.References: LEED Certification Agreement and other legal matters1

Light Emitting Diode (LED) is an energy efficient lamp type that is free from mercury. Mercury is a toxic metal that can pose health and environmental risks when released from broken or discarded lamps.LED lamps do not contain mercury or other hazardous substances, and they also have longer lifespans and lower energy consumption than other lamp types12.References:No mercury Lights | LEEDuser;LED Lighting
