LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

LEED Interior Design and Construction (ID+C) is a rating system that applies to projects that are a complete interior fit-out or renovation1. Data centers are one of the project types that can use this rating system, as they have specific requirements for energy efficiency, cooling, and reliability2.

LEED Rating Systems Overview

The increase in air temperature in a developed area resulting from the dark surfaces of roadways, parking lots, and tarred rooftops is known as heat island effect. Heat island effect is a phenomenon whereby urban areas experience higher temperatures than rural areas due to the absorption and re-emission of solar heat by man-made surfaces. Heat island effect can have negative impacts on human health, energy consumption, air quality, and climate change. Some strategies to reduce heat island effect include increasing vegetation cover, using reflective or green roofs, using cool or permeable pavements, and enhancing natural ventilation.

vocs are volatile organic compounds that can evaporate from paints, solvents, adhesives, and other building materials. They can cause health problems such as eye irritation, respiratory distress, headaches, and cancer. Limiting the concentration of vocs in the air protects the health of construction personnel by reducing their exposure to these harmful substances12.

LEED defines Life Cycle Assessment (LCA) as:

“Life Cycle Assessment (LCA) analyzes the environmental impacts of a service, material or product through its entire life cycle.”

This makes LCA distinct from Life Cycle Costing (LCC), which evaluates economic impact.

Lighting controls are devices or systems that can regulate the amount and quality of light in a space according to various factors, such as user preferences, natural light availability, occupancy, and time of day. By doing so, lighting controls can improve occupant comfort and save energy throughout the building. Lighting controls can enhance the visual comfort, well-being, and productivity of the occupants by providing them with appropriate and adjustable light levels for different tasks and moods. Lighting controls can also reduce the energy consumption and environmental impact of the lighting system by avoiding unnecessary or excessive lighting, which can waste electricity, generate heat, and contribute to greenhouse gas emissions.Lighting controls are an essential component of green building design and certification, such as LEED v4, which has adopted ASHRAE Standard 90.1-2010 as the baseline for energy performance and lighting requirements. LEED v4 also recognizes and rewards various lighting control strategies, such as automatic shutoff, light-level reduction, daylight harvesting, exterior lighting control, and plug-load control. References: [LEED Link: Minimum Energy Performance], section “LEED v4 BD+C: Minimum Energy Performance”; [LEED Link: Lighting Controls], section “LEED v4 BD+C: Lighting Controls”

Water Efficiency is the only credit category that does not have a prerequisite in LEED v4 for Building Design and Construction. Prerequisites are the minimum requirements that all projects must meet to be eligible for LEED certification. They are mandatory and non-weighted, meaning they do not contribute to the project’s score. The other credit categories have at least one prerequisite each, as shown in the table below:

Strategies for improving building occupants’ comfort and control may consist of installing operable windows, giving occupants lighting control and providing ergonomic furniture. These strategies can enhance the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants. Installing operable windows can allow occupants to adjust the natural ventilation, temperature, and fresh air intake of their spaces. Giving occupants lighting control can allow them to adjust the artificial lighting levels, color, and direction of their spaces. Providing ergonomic furniture can support the physical comfort, posture, and well-being of the occupants12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

 Flush out process is performed to remove volatile organic compounds (VOCs) from the indoor air after construction or renovation12. VOCs are chemicals that can evaporate at room temperature and cause health problems, such as headaches, nausea, and irritation3. Flush out process involves supplying 100% outdoor air to the building for a certain period of time or until a certain amount of air changes are achieved12.
