Willdan Selected by the City of Seattle to Implement Energy Design Assistance Program

Willdan Group, Inc. (NASDAQ: WLDN) announced today that the City of Seattle has awarded Willdan a four-year contract to implement its Seattle City Light Energy Design Assistance Program. Under this contract, Willdan will provide technical assistance that supports energy-efficient design decisions in the development of new multifamily and commercial buildings. Willdan will also partner and subcontract with qualified, local women- and minority-owned businesses, sharing knowledge and its NEO® software – a simplified energy modeling tool – to demonstrate ways to enhance the businesses’ current skillsets and broaden their impact in the industry.

“To achieve our vision of a shared energy future as a city, the next generation of buildings will need to be designed with electrification and energy efficiency in mind,” said Patrick Campbell, Program Manager for Seattle City Light. “This program moves us closer to these goals by giving design teams access to the tools and knowledge needed to effectively evaluate energy-efficient options.”

“We’re pleased that Seattle City Light is an early municipal adopter of energy modeling to advance decarbonization,” said Mike Bieber, Willdan’s CEO. “Our tech-enabled approach allows utilities of all sizes to cost-effectively meet growing demands for new construction while also addressing energy goals and following strict energy codes.”
