Building performance and compliance expertise, built over more than a decade.

Since 2012, our work has centered on helping commercial and multifamily building owners navigate increasingly complex requirements affecting their properties. Over the years, that experience has grown across two disciplines that now intersect more than ever—energy efficiency and building performance, and hands-on regulatory compliance.

That combination matters.

Some firms approach Building Performance Standards primarily from an energy and engineering perspective. Others focus largely on satisfying regulatory requirements. Our experience brings both perspectives together. We understand the importance of evaluating how a building uses energy, identifying practical opportunities to improve efficiency, and ensuring that every aspect of the process—from planning and documentation to reporting and ongoing requirements—is properly managed in accordance with applicable regulations.

That experience forms the foundation of MullProp Advisors. We bring together building performance and regulatory compliance expertise to help commercial and multifamily building owners navigate Washington and Oregon's evolving Building Performance Standards. From benchmarking and building assessments to Energy Management Plans, O&M programs, and compliance reporting, we manage the process with a practical, hands-on approach and clear communication every step of the way.

We understand the challenges owners and property managers face as requirements continue to evolve. By managing the complexity of building performance and compliance, we allow you to stay focused on your day-to-day operations—knowing your building's requirements are being handled by a trusted partner committed to responsive service and dependable support.

Our goal is simple: advance building energy efficiency, simplify compliance, deliver exceptional service.
