VCA Green Enhances Sustainability Practices Through Green Econome Acquisition

On November 5, 2025, VCA Consultants (VCA) announced a significant step forward for its sustainability division, VCA Green. The firm successfully acquired Green Econome, a Los Angeles-based consultancy specializing in sustainability strategies. This acquisition marks a pivotal expansion of VCA Green's service offerings and underscores both companies' commitment to driving sustainability across the entire building lifecycle.

Green Econome has built its reputation around lifecycle strategies and performance reporting in the building sector. Their focus on efficiency consulting complements VCA Green's established strengths in energy modeling and project management—creating a synergistic union that promises to enhance the overall resilience and sustainability of buildings. The combined expertise aims to equip clients with robust sustainability solutions that adhere to recognized standards, including ENERGY STAR®, LEED®, CALGreen, and Title 24.

Bridging Expertise for Comprehensive Solutions

The integration of Green Econome offers VCA Green the ability to serve not only new construction projects but also the existing building stock, which is increasingly important given the growing emphasis on sustainability in urban environments. As Marika Erdely, the founder and former CEO of Green Econome, now a principal at VCA Green, noted, “This acquisition enables us to provide lifecycle services—from code compliance through long-term cost reduction strategies.” This dual approach means clients can expect continuous support from project inception to long-term operational efficiency.

Both companies share a “People First” philosophy, valuing the individuals within their teams as much as their projects. This culture of collaboration is anticipated to drive innovation and foster an environment ripe for developing cutting-edge solutions that meet the evolving needs of building owners and operators.

Robyn Vettraino, a principal and co-leader at VCA Green, acknowledged the monumental addition that Green Econome brings to their workforce: “Green Econome brings extraordinary talent and visionary expertise into the VCA family. Our shared culture, values, and purpose position us to deliver enduring value for our clients—and to lead the industry in sustainability, innovation, and operational excellence.”

A Bright Future for Sustainable Practices

As sustainability becomes an essential element in construction and real estate, the combined capabilities of VCA Green and Green Econome will cater to a broader client base looking to enhance their environmental impact. This partnership represents a significant milestone in the field of sustainability consulting, as the unified team will leverage their complementary expertise to provide innovative sustainability frameworks.

With over 40 years of experience, VCA is committed to advancing sustainable engineering practices and offering comprehensive services that include structural designs, public sector building safety, and a commitment to sustainability across all projects. Meanwhile, Green Econome has dedicated its expertise to helping building managers enhance operational performance and navigate compliance with emerging energy and water efficiency standards.

The merging of these two firms not only enhances their service platforms but also fosters a collaborative environment focused on collective success and sustainability impact. As industries worldwide continue to grapple with environmental challenges, this acquisition is a testament to the commitment of both VCA Green and Green Econome towards a sustainable future.

In conclusion, VCA Green's acquisition of Green Econome positions them as a formidable player in the sustainability consulting landscape, ready to meet the demands of modern building performance management while championing environmental responsibility. Clients can look forward to a unified approach that amalgamates the best practices from both firms, ensuring high-quality outputs and a measurable impact on sustainable development in the years to come.
