Sustainability Strategy
Materiality, baseline, and target-setting work that ties carbon and energy goals to operational realities and capital plans — not a slide deck that gathers dust.
Strategy + Compliance
Building Performance Standards Consulting
We help organizations build a sustainability strategy that survives contact with operations — and then we help execute it. That means measured baselines, defensible disclosures, decarbonization roadmaps, and compliance programs that keep your portfolio under cap across every active US and EU building performance standard, with submetering as the connective tissue.

US Building Performance Standards
Where the caps already bite — and how submetering keeps you under them
Every active US BPS scheme penalizes the same thing: emissions or EUI you cannot prove you have controlled. Submetering converts that risk into evidence — at the building, fuel, and end-use level the administrators actually accept.
Local Law 97 — New York City
Buildings over 25,000 sq ft face hard carbon caps that tighten in 2030 and again in 2035. Penalties are tiered rather than flat: the headline rate of $268 per tCO₂e applies to emissions over a building's annual cap, while separate schedules apply to failure-to-file and misrepresentation, and alternative pathways can change the effective exposure. Confirm your building's applicable schedule with DOB.
Submetering role
Tenant and end-use submetering separates landlord-controlled emissions from tenant loads, supports the GHG-emissions reports DOB requires, and proves the load reductions credited against the cap.
BERDO 2.0 — Boston
Boston's emissions standard sets declining carbon intensity limits through 2050 with alternative compliance payments of roughly $234 per tCO₂e for any building that misses its trajectory.
Submetering role
Fuel-level submetering (gas, steam, electric) lets owners isolate fossil loads scheduled for electrification and document the emissions reductions BERDO's reporting portal requires each year.
BEPS — Washington DC
DC's Building Energy Performance Standards require buildings over 10,000 sq ft to meet ENERGY STAR or site EUI thresholds each five-year cycle, with civil penalties and an Alternative Compliance Pathway for under-performers.
Submetering role
End-use submetering identifies which systems are dragging EUI above the threshold and quantifies the savings from each ACP-eligible retrofit — required evidence for the Performance or Prescriptive pathways.
Local Law 84 / 88 — NYC Benchmarking & Submetering
LL84 mandates annual ENERGY STAR Portfolio Manager benchmarking; LL88 requires non-residential tenant submetering with monthly statements for any tenant space over 5,000 sq ft.
Submetering role
LL88 is, in effect, a submetering law. Compliant electric submeters with monthly tenant statements are the deliverable — and the same data feeds LL84 benchmarking and LL97 reports without rekeying.
Energize Denver — Colorado
Denver's BPS sets interim site EUI targets in 2024 and 2027 and a final target in 2030 for buildings over 25,000 sq ft, with fines of $0.30–$0.70 per kBtu over the gap.
Submetering role
Interval electric and gas submetering pinpoints whether HVAC, plug loads, or process equipment are driving EUI overage, so owners can model the most efficient route to each milestone.
St. Louis BEPS — Missouri
St. Louis was the first Midwest city to adopt a BPS, requiring buildings over 50,000 sq ft to hit site EUI standards by 2027 with civil penalties for non-compliance.
Submetering role
Submetering data establishes a defensible baseline ahead of the 2027 deadline and supports the Alternative Compliance Plans the city accepts for buildings that need extra time.
Maryland BEPS — Statewide
Maryland's BEPS applies to buildings over 35,000 sq ft, requiring direct GHG emissions reductions of 20% by 2030 against a 2025 baseline and net-zero direct emissions by 2040.
Submetering role
Fuel-specific submetering proves direct-emissions reductions — exactly what Maryland's standard measures — and separates them from grid-decarbonization gains.
Washington State Clean Buildings Act
The Clean Buildings Performance Standard covers commercial buildings over 50,000 sq ft (Tier 1) and over 20,000 sq ft (Tier 2) with EUI targets and penalties up to $5,000 plus $1 per sq ft per year.
Submetering role
Energy Management Plan and Operations & Maintenance documentation both lean on metered interval data; submetering shortens the audit and shrinks the conditional-compliance window.
EU & UK Building Performance Standards
EPBD, Décret Tertiaire, MEES, GEG — and the metering layer underneath
European standards moved from disclosure to enforcement faster than most owners expected. The common denominator across every member-state regime is granular, audit-ready energy data — exactly what a properly designed submetering deployment delivers.
EU EPBD Recast (2024)
The recast Energy Performance of Buildings Directive requires zero-emission new buildings from 2030 and forces deep renovation of the worst-performing 16% of non-residential stock by 2030 and 26% by 2033.
Submetering role
Member states are transposing EPBD's metering, sub-metering, and EPC requirements into national law. Granular submetering is the path to evidencing both whole-building EPC ratings and individual unit performance.
France — Décret Tertiaire (Éco Énergie Tertiaire)
Tertiary buildings over 1,000 m² must cut final energy consumption 40% by 2030, 50% by 2040, and 60% by 2050 versus a chosen reference year, reported annually through the OPERAT platform.
Submetering role
OPERAT submissions require energy use by fuel and, increasingly, by usage type. End-use submetering produces the per-usage breakdown ADEME expects and prevents the default penalties applied when data is missing.
UK MEES & ESOS
Minimum Energy Efficiency Standards make it unlawful to let most commercial properties below EPC band E, with band C targeted for 2027 and band B for 2030. ESOS Phase 3+ mandates four-yearly energy audits for large undertakings.
Submetering role
Submetered end-use data feeds both the EPC modelling that drives MEES ratings and the 90%-of-consumption metering coverage ESOS auditors now require for high-quality submissions.
Germany — GEG (Gebäudeenergiegesetz)
Germany's Building Energy Act sets primary-energy and renewable-heat requirements for new and existing non-residential buildings, with stricter thresholds tied to the 65%-renewable heating rule that took effect in 2024.
Submetering role
Heat, gas, and electric submetering quantifies the renewable share of heating loads and documents the efficiency gains needed to satisfy GEG's reference-building methodology.
Ireland — NZEB & EPBD Transposition
Nearly Zero-Energy Building requirements apply to all new and major-renovation non-domestic buildings, with BER (Building Energy Rating) disclosure on sale or lease.
Submetering role
Interval submetering supports the operational-rating data SEAI is moving toward and gives owners the evidence base to defend BER ratings during disputes.
Netherlands — Energy Label C & Information Obligation
Office buildings over 100 m² must hold at least Energy Label C, and the Information Obligation (EML) requires reporting on energy-saving measures with payback under five years.
Submetering role
Submetered consumption data is the cleanest way to prove that EML-listed measures were implemented and operating as intended — the threshold for closing out the Information Obligation cycle.
CSRD & EU Taxonomy
The Corporate Sustainability Reporting Directive (ESRS E1) and EU Taxonomy alignment require audit-grade Scope 1, 2, and 3 emissions disclosures from a rapidly expanding set of in-scope companies.
Submetering role
Asset-level submetering is the only path to defensible location- and market-based Scope 2 figures — the same data underpins Taxonomy alignment screening for the Climate Change Mitigation objective.
Why Submetering Is the Common Thread
One dataset. Every framework.
Owners that try to comply jurisdiction-by-jurisdiction end up with parallel spreadsheets, conflicting numbers, and audit findings. Owners that comply from a single submetered dataset report once and reuse everywhere.
Defensible Baselines
Every BPS scheme — from LL97 to Décret Tertiaire — starts with a baseline. Interval submetering by fuel and end-use builds that baseline once and reuses it across every framework.
Tenant vs. Base-Building Separation
Tenant submetering isolates landlord-controlled emissions from tenant loads — critical for LL88, BERDO tenant disclosures, EPBD individual-unit metering, and green-lease cost recovery.
Measurement & Verification
Pre/post submetering proves the savings claimed in compliance pathways, ACP filings, and 179D deductions — the M&V evidence that auditors and program administrators actually accept.
Multi-Jurisdiction Reporting
One metered dataset can feed LL97, BERDO, BEPS, OPERAT, EPC, and CSRD submissions — eliminating the duplicated, error-prone spreadsheets that triggered most penalty letters last cycle.

Quick Wins
No- and low-cost measures that move the meter
Long-horizon roadmaps work best when the first year already delivers. These are the measures we look for first because they pay back fast and build momentum for everything that follows.
Lighting & Controls Tune-Up
Schedule changes, occupancy sensors, and setpoint discipline that cut consumption within a billing cycle — usually no capital required.
HVAC Setpoint & Schedule Review
Right-size deadbands, eliminate simultaneous heating and cooling, and recover the savings BMS drift quietly erased.
Tariff & Rate Optimization
Re-evaluate rate class, demand windows, and time-of-use exposure against your actual interval data to find money already on the table.
Compressed Air Leak Audit
Ultrasonic leak surveys and pressure-band tightening typically pay back in months on any plant running rotary screws around the clock.

Building performance standards questions
What is a building performance standard?
A local or national requirement that an existing building meet a performance target — usually an emissions or energy-use intensity cap — by set compliance dates, with penalties for exceeding it. Unlike energy codes, which apply at construction or major renovation, these standards apply to buildings already in operation and tighten over time.
Which jurisdictions currently have one?
In the US, Local Law 97 in New York City, BERDO 2.0 in Boston, BEPS in Washington DC, Energize Denver, St. Louis BEPS, Maryland's statewide BEPS, and the Washington State Clean Buildings Act, among others. In Europe, the EPBD recast, France's Décret Tertiaire, UK MEES and ESOS, and Germany's GEG operate on similar logic with different metrics.
How do we know whether we are over the cap?
By benchmarking measured consumption against the applicable cap for your building type and compliance period. That requires knowing what the building actually consumes, split correctly between base building and tenant loads — which whole-building utility bills usually cannot do on their own.
Why does submetering matter for compliance?
Caps are enforced against measured performance, and most disputes come down to attribution: which load belongs to which party, and what the baseline was. Circuit-level and utility-level interval data separates tenant from base-building consumption, supports the measurement and verification behind any improvement you claim, and produces the same dataset across multiple reporting frameworks.
What are the penalties for non-compliance?
They are set by each jurisdiction and typically scale with the amount by which a building exceeds its cap, assessed per compliance period. Because they recur rather than being one-time, the cost of staying over the cap compounds — which is what usually drives the capital case for acting before a deadline.
Can renewable energy credits be used to comply?
In some jurisdictions and within specific limits, yes; in others RECs address only market-based Scope 2 reporting and do nothing for the local cap. The rules differ by program and change as standards are revised, so eligibility has to be confirmed for the specific building and compliance year before it is counted on.
Where should a portfolio start?
With a defensible baseline: know current performance per building, which standards apply, and which compliance dates come first. From there, no- and low-cost measures — lighting controls, HVAC schedules, tariff review, compressed air leaks — usually move the meter before any capital project is approved.
Can compliance work be combined with rebates or tax incentives?
Frequently. Efficiency measures undertaken for compliance may qualify for utility rebate programs, and improvements meeting the relevant efficiency thresholds may support the 179D deduction — a deduction, not a credit, and a question for your tax advisor. We model incentives alongside the compliance path so the sequence is right.
