How does LEED define energy-efficient appliances?

LEED defines energy-efficient appliances as those that consume less energy compared to standard models. This definition aligns with the program's goal of promoting sustainability and reducing overall energy consumption in buildings. Energy-efficient appliances are designed to use advanced technology to minimize energy use while still delivering the same level of performance as their conventional counterparts. This includes items such as refrigerators, dishwashers, and washing machines that bear energy efficiency certifications like ENERGY STAR, which indicates that they meet or exceed certain energy-saving criteria.

The other choices do not fit the definition of energy-efficient appliances. For example, appliances made exclusively from renewable resources or those that operate solely on solar energy describe sourcing and operational modalities, rather than energy consumption standards. Additionally, larger-sized appliances do not inherently imply energy efficiency and may actually use more energy. Thus, the focus on reduced energy consumption as defined aligns closely with LEED's mission to enhance energy performance.
