Building Energy Performance Standards: What Ontario Businesses Need to Know Now

An accessible guide to Ontario’s Building Energy Performance Standards. Learn what the new standards require, why they matter for building owners, and how to prepare for changing energy and emissions performance expectations.

Building Energy Performance Standards: What Ontario Businesses Need to Know Now

Building energy performance standards are arriving in Ontario—and they’re about to change how commercial buildings are evaluated, financed, and managed. While most businesses are focused on compliance, the real story is strategic: those who move early can reduce costs, boost asset value, and lead in sustainability performance. This blog explains what’s coming, who it affects, and what decision-makers should be doing right now.

Governments across Canada are no longer just encouraging energy efficiency—they’re requiring it. That shift is rooted in the country’s 2050 net-zero targets and the growing recognition that commercial buildings are among the top emitters.

These new performance rules are designed to:

And they’re doing more than shaping sustainability outcomes—they’re introducing accountability.

For CFOs, facility managers, and asset leaders, the impact is straightforward:

  • Reputation — Expect public benchmarking of energy performance
  • Valuation — Inefficient buildings could signal risk to investors
  • Deals — Leasing, refinancing, and insurance negotiations may soon include energy benchmarks

Energy use will no longer be hidden—it’ll be a measure of operational performance and strategic oversight.

Top-performing portfolios are getting ahead, not just to comply, but to compete. They’re treating building performance as a financial lever:

  • Cutting long-term costs through HVAC optimization and recommissioning
  • Showing ESG progress to attract investment and better financing terms
  • Positioning their assets to meet the future of tenant and investor expectations

And they’re doing it while incentive funding is still on the table.

Here’s what decision-makers should prioritize immediately:

Start with a professional energy audit to identify how your building performs compared to peers.

Recommission existing systems, optimize HVAC, and calibrate controls. These low-cost actions deliver fast savings.

Consider implementing solar onsite generation to offset grid use, reduce Global Adjustment (GA) costs, and lock in long-term price stability.

Use programs like the IESO Retrofit for electric efficiency, and Enbridge’s custom commercial incentives for gas-saving retrofits, to reduce upfront costs and accelerate ROI.

This isn’t about just compliance—it’s about building operational resilience and protecting margins.

Across 1.5M+ sq. ft. of Ontario facilities, Green Integrations uncovered:

  • Up to 38% energy use variance in similar buildings
  • 5–10% annual energy cost savings from basic measures
  • <4-year paybacks on key retrofits even before incentives

These aren’t theoretical savings – they’re being realized now by operators acting ahead of the curve.

Energy performance mandates are coming – and with them, a new lens on building value. Acting now means you’re not reacting later.

Frequently asked questions

Building Energy Performance Standards (BEPS) are Ontario regulations that require large commercial and institutional buildings to meet defined energy performance thresholds. BEPS is administered under the Ontario Green Buildings Statute Law Amendment Act and applies to buildings over a specified gross floor area. Buildings that do not meet the standard by the applicable deadline face compliance obligations that may include mandatory retrofits or reporting requirements.
BEPS applies to large commercial, industrial, and institutional buildings in Ontario above the regulated floor area threshold. The initial phase targets the largest buildings — those over 100,000 square feet — with subsequent phases expanding the scope to smaller buildings on a defined regulatory timeline. Building owners should confirm their specific obligations with a qualified energy advisor or review the Ontario Ministry of the Environment, Conservation and Parks guidance directly.
BEPS compliance is phased — specific deadlines vary based on building size, type, and energy use intensity. The regulation is active and Ontario building owners should treat BEPS as an immediate planning issue, not a future one. An energy baseline established now — through interval data analysis and an on- site assessment — gives building owners the documentation they need to understand their current position relative to the standard and to plan retrofits on a commercially sensible timeline.
BEPS compliance requires buildings to meet a maximum Energy Use Intensity (EUI) threshold specific to the building type. Buildings that exceed the threshold must implement energy performance improvements. The compliance process includes establishing a documented energy baseline, identifying the gap between current performance and the required EUI, and executing the measures needed to close that gap within the regulated timeline.
An integrated approach — reducing consumption through efficiency measures first, then adding solar generation — addresses BEPS from both sides: it lowers the facility's Energy Use Intensity (reducing consumption) and offsets grid electricity purchases (reducing the facility's carbon and cost footprint). Efficiency measures such as HVAC recommissioning, BAS optimisation, and LED lighting retrofits are typically the fastest path to EUI reduction, while solar provides the long-term generation offset that supports ESG and GHG reporting requirements.
