No later than two years after the project’s substantial completion.
What are LEED Addenda?
Changes and improvements incorporated into the LEED rating systems and reference guides to help clarify, correct, interpret, or provide alternative language. Addenda are subject to USGBC committee review and are published as frequently as quarterly.
Which components of a building are covered under the LEED BD+C: Core and Shell Rating System?
Structure, envelope, and building level systems, such as the HVAC.
How is a LEED Project boundary determined if there are multiple buildings onsite?
The project team determines the boundary.
How should a project team proceed when addenda is published after a project’s registration date?
Recommended to follow addenda published after their registration date. It is not mandatory. Must follow addenda published before project’s registration date.
What is the purpose of LEED Pilot Credit Library?
The pilot credit process allows project to test future credits and prerequisites before they are proposed to be included int he next versions.
What is “gerrymandering” in terms of LEED?
Project teams excluding land for the purpose of complying with a credit or prerequisite.
How can a project team ensure success prior to submitting LEED documentation?
Proofreading.
Checking numerical values for consistency across credits.
Checking the application for completeness.
What is the next step to take if the team learns they are a single point away form the achieving LEED Gold certification after they receive LEED reviewer’s response from the preliminary review.
Accept the preliminary review results as final if they are satisfied.
Submit new or revised documentation
Attempt additional credits before submitting the project for final review.
What should a project team do when experiencing difficulty determining a LEED Project Boundary due to project conditions
Review the minim program requirements (MPRs).
What are the 3 goals of the MPRs
Give clear guidance to customers
reduce complications that occur during the LEED certification process.
major trade-off of increasing glazing in a building’s façade to maximize daylight and views?
less insulation compared to exterior walls, increasing demand for heating and cooling.
LEED professional who can be included on team for 1 point on Healthcare Project?
LEED AP with the appropriate specialty for the rating system being pursued can earn a point through IN Credit - LEED AP
Most suitable rating system for a mixed-use project that has two stories of retail space and four stories of hotel space?
LEED BD+C Hospitality - 60% of floor area falls under hospitality rating system adaptation.
What are LEED Interpretations?
Official precedent-setting answers to formal technical inquiries about implementing LEED on a project.
Difference between LEED Interpretations and CIRs?
LEED Interpretations are precedent-setting, which means all projects must adhere to all LEED Is. Also reviewed by LEED committees. CIRs are project specific.
Mixed use project that includes office space building, two residential buildings, and hotel on master site owned by the same owner. What program can save the team time and streamline LEED certification process for each building to have it’s own certificate?
LEED Campus program.
Role of a project administrator?
Manages team and oversees the certification documentation.
Role of LEED Technical Advisory Group?
recommend technical solutions to rating system development and maintenance issues.
Purpose of Alternative Compliance Path?
Provide additional options and approaches that address unique circumstances and accommodate advancements in science and technology.

Tradeoff for increased ventilation of an office building?
increased consumption for heating and cooling additional outdoor air, negatively impacting energy use reduction goals.
