USGBC Updated LEED-AP-BD+C Exam Questions and Answers by marley

For major renovation and new construction projects, the required energy and water-related system analyses should be the same except for plug and process load needs. Plug and process loads are the electrical loads that are not related to lighting, heating, ventilation, and air conditioning (HVAC)systems, such as computers, appliances, equipment, and machinery. Plug and process load needs may vary depending on the type and function of the building, and they can have a significant impact on the energy performance and demand of the building. Therefore, the project team should analyze the plug and process load needs for each project and design strategies to reduce or optimize them. The other factors, such as site conditions, massing and orientation, and building envelope performance, are common to both major renovation and new construction projects, and they should be analyzed in the same way for both types of projects.

According to the LEED v4 Reference Guide for Building Design and Construction, the Thermal Comfort credit requires providing individual comfort controls for at least 50% of individual occupant spaces, and group controls for 100% of shared multioccupant spaces1. Individual comfort controls allow occupants to adjust one or more of the following: air temperature, air speed, radiant temperature, or humidity. Group controls are shared by two or more occupants within a thermal zone.The credit aims to promote occupants’ productivity, comfort, and well-being by providing quality thermal comfort.References: EQ Credit Thermal Comfort, LEED v4 Reference Guide for Building Design and Construction123

Decreasing lighting power is a strategy that can be used to reduce the internal load of a building.Internal load is the amount of heat generated within a building by its occupants, equipment, and lighting1.Reducing lighting power can lower the internal heat gain and thus decrease the cooling demand and energy consumption of the building2.Other strategies to reduce internal load include using energy-efficient appliances, natural ventilation, daylighting, occupancy sensors, and shading devices3.References:

The correct answer is B. Provide for at least 10% of all regular building occupants, with no less than five storage spaces per building.

According to the LEED v4.1 Bicycle Storage Requirements1, commercial projects must provide long-term bicycle storage for at least 10% of all regular building occupants, with no less than five storage spaces per building. Long-term bicycle storage is defined as secure, enclosed, and weather-protected spaces that are intended for use by occupants who make regular trips to the project building.Examples of long-term bicycle storage include lockers, cages, rooms, or dedicated areas within buildings1. The purpose of this requirement is to encourage the use of bicycles as a sustainable mode of transportation and reduce greenhouse gas emissions and fossil fuel consumption.
