Question
Which label or certification indicates reduced water consumption for appliances?
A. GREENGUARD
B. ASHRAE 90.1
C. ISO 14001:2015
D. ENERGY STAR
Answer
D. ENERGY STAR
Explanation
ENERGY STAR is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy that promotes energy efficiency. Products that earn the ENERGY STAR label meet strict criteria for energy efficiency and often for water efficiency as well, helping consumers save money on utility bills and protect the environment through energy-efficient products and practices.
The ENERGY STAR label is used to certify appliances and products that meet strict energy efficiency and water consumption standards set by the U.S. Environmental Protection Agency (EPA). Appliances such as dishwashers, washing machines, and water heaters that have earned the ENERGY STAR label use significantly less water compared to standard models.
For example, an ENERGY STAR certified dishwasher uses 12% less energy and 30% less water than standard dishwashers. ENERGY STAR washing machines use around 45% less water than conventional washers. By reducing hot water usage, ENERGY STAR appliances also help save energy needed to heat the water.
The other certifications listed are not primarily focused on water efficiency:
A. GREENGUARD – an indoor air quality certification for low-emitting products and materials
B. ASHRAE 90.1 – energy standard for buildings, not a product label
C. ISO 14001:2015 – environmental management system standard, not a product water efficiency label
Therefore, ENERGY STAR is the label that specifically indicates reduced water consumption in appliances, making it the best answer for this LEED Green Associate Exam question.
