The WaterSense labeled homes program is designed to encourage the construction and purchase of water-efficient, high-performing homes. In 2020, EPA is rolling out Version 2.0 of the WaterSense labeled homes program. Version 2.0 minimizes mandatory requirements and transitions to a more performance-based efficiency requirement. EPA aims for these changes to remove many of the technical and administrative barriers many builders have encountered in building WaterSense labeled homes. WaterSense labeled homes Version 2.0 will increase flexibility, adapt to changes in the building industry, and expand the reach of the program so that a broader range of builders and professionals can participate.

Whole-house mechanical ventilation plays a critical role in the ENERGY STAR Single-Family New Homes program. It helps ensure that efficiency is not achieved by sacrificing indoor air quality. Delivering an effective system is a three-step process that involves the HVAC designer, the HVAC contractor or electrician, and the Rater. This technical bulletin is designed to reinforce the responsibilities of each party with regards to the whole-house ventilation airflow rate.
