According to the LEED v4 Minimum Program Requirements (MPRs), there is no minimum required number of occupants or full-time equivalents (FTEs) for which a building must be designed to be considered eligible to pursue certification1. However, the project must serve at least one FTE, which is based on an 8-hour day2. The other options are not part of the MPRs.

Graywater refers to wastewater that is not heavily soiled, typically from bathroom sinks, showers, tubs, and washing machines. It does not include water from toilets (which is considered blackwater) or kitchen sinks (which can contain food waste). Graywater can be treated and reused for purposes like landscape irrigation, which can save water and earn LEED points. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Pervious paving, also known as permeable paving, allows water to pass through it, facilitating the recharging of aquifers. This type of paving reduces runoff by allowing water to soak into the ground, which can help replenish groundwater supplies and reduce the impact on nearby water bodies. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

An occupant survey is the most efficient way for building users to rate the heating and air-conditioning and other aspects of work spaces. An occupant survey is a tool that collects feedback from building occupants about their satisfaction with various aspects of their indoor environment, such as thermal comfort, lighting quality, acoustic quality, air quality, and spatial layout. An occupant survey can help identify areas for improvement, monitor performance, evaluate design strategies, and inform future decisions. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “conduct occupant surveys on thermal comfort” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Occupant Surveys | Center for the Built Environment]

According to the Indoor Environmental Quality credit category of LEED, mechanical and electrical rooms are considered unoccupied spaces. These spaces are typically not intended for human occupancy, except for maintenance or operational purposes, and therefore do not require the same level of environmental control (such as ventilation or temperature control) as occupied spaces. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

 LEED is an acronym for Leadership in Energy and Environmental Design, which is the most widely used green building rating system in the world. LEED provides a framework for creating healthy, efficient, and cost-saving buildings that have positive environmental and social impacts. LEED certification is a globally recognized symbol of sustainability achievement and leadership12.

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”

Building orientation is the element of design that can be used to take advantage of natural ventilation, solar energy and daylight. Building orientation refers to the position and direction of a building in relation to the sun, wind, and other environmental factors. By orienting a building properly, it can maximize the benefits of passive design strategies such as daylighting, natural ventilation, and solar energy. For example, a building can be oriented to face the south or north in temperate climates to capture more sunlight for heating and lighting, or to face the east or west in hot climates to avoid excessive solar heat gain and glare. A building can also be oriented to align with the prevailing wind direction to enhance natural ventilation and cooling. Building orientation can also affect the shape, size, and placement of windows, doors, roofs, and other architectural elements that influence the performance and comfort of a building. References: Passive Design Strategies | Sustainability Workshop, section “Building Massing & Orientation”; Back to Basics: Natural Ventilation and its Use in Different Contexts | ArchDaily, section “Orientation”; Courtyard configuration to optimize shading, daylight and ventilation …, section “Introduction”

LEED impact categories are the environmental, social, and economic issues that LEED projects aim to address1. They provide an overview of the market transformation that technical requirements work to achieve, as well as a guide to where points should be assigned2. The categories focus on LEED’s social, environmental, and economic goals, and they assess each strategy based on its ability to achieve those goals3.

One of the values and benefits of building green is that it will enhance the health of the building occupants. Building green is a process that incorporates environmental considerations into every stage of a building’s life cycle, from design to construction to operation to end-of-life. Building green can improve 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. Building green can enhance IEQ by using low-emitting materials, providing adequate ventilation, controlling temperature and humidity, optimizing daylighting and lighting quality, reducing noise levels, and promoting occupant well-being12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2
