Leadership in Energy and Environmental Design (LEED) LEED-AP-ID+C Reddit Questions

To meet the requirements for Indoor Environmental Quality Credit, Interior Lighting, Option 1, the design team should specify lighting controls that enable adjustments to suit individual tasks and preferences. This includes providing controls that allow for on, off, and at least one intermediate light level, such as 50%. Overhead lighting with these controls for the open-office space would meet this criterion.

References: The LEED reference guide for Interior Design and Construction provides detailed information on the requirements for lighting controls under the Indoor Environmental Quality Credit, Interior Lighting, Option 1. Specifically, it states that for at least 90% of individual occupant spaces, there must be individual lighting controls that enable occupants to adjust the lighting to suit their tasks and preferences, with at least three lighting levels or scenes (on, off, midlevel) 1.

To earn the Innovation Credit, LEED Accredited Professional for an Interior Design and Construction project, a LEED AP with ID+C specialty must submit their credentials as a principal participant of the project team. This is because the ID+C specialty credential signifies technical knowledge specific to the design and construction of environmentally conscious commercial interiors, which is essential for the project’s certification process1.

• LEED v4.1 ID+C updated guidance on the LEED Accredited Professional Innovation point, which allows for the LEED AP ID+C credential to count towards this point1.
• The LEED credit library and the LEED v4: Interior Design + Construction Guide, which provide detailed information on the requirements for earning Innovation credits23.

For the Water Efficiency Prerequisite, Indoor Water Use Reduction, cooling towers and evaporative condensers must have makeup water meters to measure the amount of water used, conductivity controllers to optimize water quality and minimize consumption, and overflow alarms to prevent excess water use.

References: The LEED v4 Indoor Water Use Reduction Calculator is a tool that includes assumptions for baseline water use and helps in documenting water use reduction strategies, which would involve the use of makeup water meters and conductivity controllers1. Additionally, the LEED v4 reference guide for water efficiency credits outlines the need for water use reduction and the strategies to achieve it, which align with the requirements of makeup water meters and conductivity controllers2.

 The Construction and Demolition Waste Management Calculation requires information about the waste stream (the different types of materials being disposed of), the total amount of waste generated, the amount of waste diverted from landfill through recycling or reuse, and the amount of waste that is actually sent to the landfill.

References: This information aligns with the LEED AP Interior Design + Construction (LEED AP ID+C) V4 guidelines, which emphasize the importance of waste management planning in sustainable building practices1.
