Wisconsin Energy Codes

Building a Strong Foundation for Wisconsin Energy Codes

About us

Welcome to the Building a Strong Foundation for Wisconsin Energy Codes program an initiative aimed at strengthening the resilience and sustainability of buildings throughout Wisconsin. We focus on the adoption and integration of building energy codes that promote energy efficiency, reduce environmental impact, and ensure safety in the face of natural disasters and climate change.

About us

Slipstream and a team of state and regional partners have received a U.S. Department of Energy (DOE) award to advance the development, adoption, and compliance of energy codes in Wisconsin. The award is part of the DOE's Resilient and Efficient Codes Implementation awards, funded by the Bipartisan Infrastructure Bill, to ensure the nation's buildings meet the latest standards for energy efficiency.

Slipstream, the Wisconsin Department of Safety and Professional Services (DSPS), Clean Wisconsin, the Wisconsin Local Government Climate Coalition (WLGCC), Midwest Energy Efficiency Alliance (MEEA), and New Buildings Institute (NBI) link arms to strengthen Wisconsin’s ability to enact residential and commercial energy codes that reduce energy use and bring the state closer to meeting its clean energy goals.

Wisconsin has gained momentum toward climate action since the state released its ambitious Clean Energy Plan in 2022 and has amassed a network of local governments eager to adopt policies that can make an environmental impact. This project will build on this traction to accelerate building performance in Wisconsin, which has lagged other Midwest states in the energy performance required of its buildings.

This project is supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) under the Building Technologies Office—DE-FOA-0002813—Bipartisan Infrastructure Law Resilient and Efficient Codes Implementation.
