2023 Residential Laundry Field Study

NEEA is in process of publishing an updated version of this report, which will be posted here once available.

The Northwest Energy Efficiency Alliance (NEEA) contracted with Evergreen Economics to conduct the 2023 Laundry Field Study. This report serves as a supplement to the 2022 Residential Building Stock Assessment (RBSA), which provides building characteristics and energy usage data on residential buildings in the Northwest.  

This report details the field study effort to document typical home laundry equipment characteristics, record consumers’ laundry processing behaviors, and collect real-time clothes washer and dryer energy data. It also describes the analysis of consumer laundry processing patterns. Furthermore, it leverages NEEA’s End-Use Load Research (EULR) project’s continuous metering data from more than 350 Northwest homes to estimate the region’s annual washer and dryer usage patterns. Together, the findings will help NEEA identify opportunities for promoting new, more efficient types of laundry processing equipment in its Market Transformation efforts.
