California's Building Performance Standards Strategy Signals a New Era for Real Estate Compliance
California has taken another major step toward transforming how large commercial and multifamily buildings are managed.
The California Energy Commission (CEC) recently released its draft Building Energy Performance Strategy in response to Senate Bill 48 (SB 48), outlining a statewide roadmap for Building Performance Standards (BPS). While the strategy is still in draft form, it provides the clearest picture yet of how California intends to improve building energy performance and reduce greenhouse gas emissions across existing buildings.
For owners and operators of multifamily housing portfolios, this isn't simply another policy announcement—it represents a fundamental shift toward continuous performance management rather than one-time compliance activities.
What the Draft Strategy Proposes
The CEC's recommendations build upon California's existing benchmarking requirements under AB 802 and propose a statewide Building Performance Standard for large existing buildings.
Key elements include:
Coverage for commercial and multifamily buildings over 50,000 square feet
Long-term building performance targets extending to 2045
Interim compliance checkpoints every five years
Performance measured using energy use intensity (EUI) and onsite greenhouse gas intensity (GHGI)
Expanded enforcement of benchmarking requirements, including stronger compliance oversight and third-party verification
Flexible compliance pathways for buildings with unique operational challenges
Strong emphasis on affordability, tenant protections, and equitable implementation throughout the program design.
Why This Matters for Multifamily Owners
California's strategy reflects a broader trend happening across North America.
Instead of asking owners to simply report utility data each year, regulators are increasingly expecting buildings to demonstrate measurable improvements in operational performance over time.
That creates new challenges:
Tracking multiple regulatory requirements
Understanding changing performance targets
Managing benchmarking accuracy
Coordinating capital planning with compliance deadlines
Monitoring portfolio-wide risk across dozens—or hundreds—of properties
Organizations that begin preparing now will be better positioned as regulations evolve.
Compliance is Becoming an Ongoing Operational Function
One notable aspect of California's proposal is its focus on long-term performance trajectories rather than one-time mandates.
This means owners will increasingly need systems that can:
Continuously monitor building performance
Identify regulatory changes early
Organize compliance documentation
Support capital planning decisions with operational data
Provide portfolio-level visibility across assets
For many organizations, spreadsheets and manual tracking will become increasingly difficult to maintain at scale.
How GreenT Helps Owners Stay Ahead
At GreenT, we've built HannaAI and our compliance intelligence platform around exactly this challenge.
Our goal is to help multifamily owners and operators move from reactive compliance to proactive portfolio management.
GreenT helps organizations:
Monitor evolving sustainability and building performance regulations
Centralize compliance information across portfolios
Automate regulatory research and reporting workflows
Improve visibility into energy benchmarking and ESG initiatives
Reduce the administrative burden placed on sustainability, operations, and asset management teams
As Building Performance Standards continue expanding across states and municipalities, having timely regulatory intelligence becomes just as important as collecting energy data.
Looking Ahead
California has historically influenced building policy nationwide, and many industry observers expect other jurisdictions to continue adopting Building Performance Standards in the coming years. While the SB 48 strategy remains in the public review process, it provides valuable insight into the direction of future building regulations.
For real estate owners and operators, the takeaway is clear:
The future of compliance is continuous, data-driven, and portfolio-wide.
Organizations that invest now in better regulatory intelligence, benchmarking visibility, and operational workflows will be better prepared for whatever comes next.
As California's regulatory landscape becomes more complex, success won't come from collecting more data, it will come from understanding what regulations mean, knowing what actions to take, and staying ahead of compliance deadlines. GreenT's HannaAI provides the regulatory intelligence and workflow automation that real estate teams need to navigate this evolving landscape with confidence.
