Building performance consulting,
from first principles to policy.
A2 Efficiency bridges MEP engineering, building energy modeling, and energy policy, delivering analysis that's constructible, not theoretical.
Three offerings.
One engineering lens.
Architects and owners come to us before the MEP engineer is hired. California design teams come to us for Title 24. Agencies and utilities come to us when they need to figure out what to incentivize next.
We define what your building's systems need to do, before the MEP contractor is hired. Used across design-build, design-assist, and traditional delivery.
- MEP Basis of Design
- Building Loads Modeling
- Electrification Strategy
- Peer Review + Bid Support
- Daylighting & Envelope Analysis
Code strategy from early design through permit submission.
- Code Strategy Review
- Preliminary Evaluation
- Full Permit Package
- AHJ Support
We help define how building performance is measured, incentivized, and scaled, from technology assessment to compliance pathway design.
- Technology Research
- Code Change Development
- Program Ideation
- Energy Efficiency Analysis
- Workforce Education
Built for early-stage decisions.
Two lightweight tools for architects and designers working through early design. No login, no paywall. Just useful answers, fast.
Enter building type, size, and California zip code to get your predicted EUI benchmarked against the AIA 2030 Challenge target for your building type.
Input 10 early-design attributes, including climate zone, HVAC type, and glazing ratio, and get the prescriptive standard design baseline for each building system.
Projects
Major retrofit eliminating on-site combustion from natural gas, piloting phase change thermal energy storage, and targeting Washington State Clean Building Act compliance.
Comprehensive MEP Basis of Design across four SF campus locations supporting design-build delivery, electrification planning, and Title 24 compliance.
NZE risk assessment and five-measure remediation plan for a high-performance SF office transitioning to a new innovation center tenant with higher energy loads.
Insights
Articles, research, and guidance on building energy performance, from code compliance to all-electric design strategy.
California's 2025 Title 24 Part 6 energy code took effect January 2026. What changed, compliance requirements, and impact on architects.
Right-sized systems are simpler to build, cheaper to operate, and easier to maintain. We model actual occupancy, schedule, and climate, not compounding safety margins.
All-electric buildings aren't a regulatory exercise. They're an opportunity to simplify systems and future-proof against utility volatility.
