ENERGY STAR Portfolio Manager

What Portfolio Manager does

Portfolio Manager takes your building's characteristics and twelve months of utility data and produces comparable performance metrics: energy use intensity, water use intensity, greenhouse gas emissions, and — where the building type is eligible — an ENERGY STAR score benchmarking it against a peer population.

In Ontario it is also the mechanism through which EWRB reporting is filed. If your building is 50,000 square feet or over, you are using Portfolio Manager whether you intended to or not.

Why owners outsource it

Setting up a single owner-occupied building is a straightforward afternoon's work. The difficulty scales sharply with tenancy.

• Meter mapping. Every meter serving the building must be included and no meter serving other premises may be. On multi-building sites and campuses this is rarely obvious.
• Tenant data aggregation. Where tenants hold their own utility accounts, whole-building consumption has to be assembled — through utility aggregation services, tenant consent, or lease provisions requiring data sharing.
• Use type classification. The peer group your building is scored against depends on it. A misclassified building is compared against the wrong population, sometimes for years.
• Data integrity. Estimated reads, meter changes, account transfers and billing-period drift all corrupt the record quietly.
• Annual maintenance. Twelve months of clean data, every year, on a deadline.

What we do

• Property set-up, or a full audit and correction of an existing record
• Meter inventory and mapping, including multi-building sites
• Tenant data aggregation, including utility aggregation requests and lease-based data collection
• Twelve-month data entry, gap identification and reconciliation against source bills
• Annual submission to Ontario and, separately, to the City of Toronto where applicable
• Score interpretation — what the number means, and whether an audit is warranted
• Annual retainer, so the deadline is ours rather than yours

Beyond compliance

Portfolio Manager benchmarking has quietly become a due-diligence document. Lenders financing commercial property, institutional tenants signing long leases, and purchasers assessing a building all increasingly ask for it. Several Canadian funding programs use it as an eligibility screen.

A building with three years of clean benchmarking history and a defensible score is in a materially better position in any of those conversations than one that has never measured. That is true whether or not reporting is legally required at your size — and Toronto's threshold drops to 10,000 square feet in 2027.
