Orange, Calif. - November 5, 2025 - VCA Consultants (VCA) announced today that its sustainability practice, VCA Green, has completed the acquisition of Green Econome, a Los Angeles-based sustainability consulting firm recognized for its lifecycle strategies, building performance reporting, and efficiency consulting.

By integrating Green Econome's expertise in benchmarking, compliance, and building performance planning with VCA Green's strengths in energy modeling, project management, and field verification, the unified team will deliver comprehensive sustainability solutions spanning the entire building lifecycle. Clients will benefit from a single platform that supports recognized standards such as ENERGY STAR®, LEED®, CALGreen, and Title 24, while driving innovation, efficiency, and measurable long-term value.
