Appliance Energy and Water Efficiency Standards

State policy that sets energy and water efficiency standards for appliances.

An Act Creating a Next-Generation Roadmap for Massachusetts Climate Policy was signed by Governor Baker on March 26, 2021.  Energy and water efficiency standards for 15 new products were a key policy adopted in this bill.  Massachusetts had standards for other products prior to the passage of the act, but the earlier standards were preempted by federal government regulations. 

Appliance efficiency standards are the best energy and climate policy you’ve never heard of.  They drive large savings of energy and water for a very low cost by barring the statewide sale of less efficient products.  The result is a transformed market where more efficient products are all that may legally be sold.  

Covered Products

The Climate Act added new energy and water efficiency standards for the following products: 

  1. commercial hot-food holding cabinets 

  1. computers and computer monitors 

  1. state-regulated general service lamps 

  1. high CRI (color rendering index) fluorescent lamps 

  1. plumbing fittings 

  1. plumbing fixtures 

  1. portable electric spas 

  1. water coolers 

  1. residential ventilating fans 

  1. commercial ovens 

  1. commercial dishwashers 

  1. commercial fryers 

  1. commercial steam cookers 

  1. spray sprinkler bodies 

  1. electric vehicle supply equipment
