Chlorofluorocarbons (CFCs) are a type of compound that was widely used in the 20th century in various applications, including as a refrigerant in air conditioning systems such as centrifugal chillers. CFCs are known to deplete the ozone layer when released into the atmosphere, and their use has been phased out in many countries under the Montreal Protocol. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The LEED minimum program requirements state that for LEED BD+C and LEED O+M rating systems, the LEED project must include a minimum of 1000 ft2 (93 m2) of gross floor area1.

LEED For Building Design And Construction (LEED BD+C) Rating Systems In Details

Building Automation Systems (BAS) are essential tools for managing and optimizing the energy performance of a building. According to the LEED v4 BD+C Study Guide under EA Prerequisite: Minimum Energy Performance and EA Credit: Optimize Energy Performance, BAS are primarily used to:

“Control and monitor mechanical, electrical, and plumbing (MEP) systems, ensuring the building operates as designed and maintains operational efficiency over time.”

“BAS are also used to monitor energy and water use and track functional performance, identify faults, and support commissioning efforts.”

BAS continuously collect real-time data from HVAC systems, lighting, and other building services to monitor functional performance, making adjustments automatically to maintain efficiency and comfort. This supports LEED goals for reduced energy consumption, occupant comfort, and building longevity.

Options C and D (life-cycle assessments and energy simulations) are typically conducted before system implementation using design software, not by BAS. Option A (efficiencies of scale) refers more to economic/business strategy, not building automation.

 Life-cycle costing is an economic analysis method that considers all costs associated with an asset over its entire life cycle, from acquisition and installation to operation, maintenance, and disposal. In this case, the building manager is comparing the total costs of owning and operating two different boilers over their respective lifetimes. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

A brownfield is a property that has been previously used for industrial or commercial purposes and may be contaminated by hazardous substances, pollutants, or contaminants12. Brownfields can pose environmental and health risks and require remediation before redevelopment3. Examples of brownfields include abandoned factories, gas stations, dry cleaners, etc

The Solar Reflective Index (SRI) is a measure of how well a material reflects solar radiation and releases absorbed heat. It is used to evaluate the performance of cool roofs, which can reduce the heat island effect by lowering the surface temperature of buildings and urban areas.

Paved surfaces absorb and retain heat, increasing local temperatures and contributing to the heat island effect. LEED encourages mitigating this effect by using materials with high Solar Reflectance Index (SRI) or implementing strategies like green roofs and shaded areas​​.

LEED promotes compact, transit-rich locations:

“Locating a project in an area that supports walking, biking, and mass transit... will result in lower GHG emissions from reduced car travel.”

Urban centers offer the best access to alternative transport and reduce reliance on fossil fuels.
