Office Owner Standardizes Operations Across Its Portfolio and Beats Projected Savings by 3.9x

The client owns, develops, and operates office assets across multiple markets. With lease terms, structures, and utility profiles that differ from one market to the next, recovering tenant utilities meant a lot of lost time and uncertainty.

Each property was also managed as an independent entity, which made it hard to compare performance, standardize engineering practices, and turn what worked at one asset into a repeatable process.

That is what brought the owner to Enertiv in 2021. Once tenant billing was deployed across the portfolio, invoices were accurate and generated in under 48 hours, with no manual reconciliation and no time lost between the read and the bill. The rollout worked well enough that the owner decided to expand into the rest of the platform, and today runs reporting, maintenance, carbon planning, and equipment efficiency optimization on one standardized system.

Key Results

• $86,012 in verified annual savings at two of the portfolio's assets, 3.9x the original projection
• Energy Star scores that improved from 91 to 94 at one asset and from 67 to 72 at another
• $0 in capital investment, with every measure delivered through BMS control changes
• 43,092 lbs of CO2e avoided annually

Reporting and Energy Management

Billing turned out to be the harder half of the problem. Once provider bills, submeter reads, and utility accounts were flowing into one validated system, the data underneath was already doing most of the work that reporting requires.

The owner moved reporting onto the same platform, with 217 utility accounts syncing automatically to Energy Star and GRESB submissions built from data that had already been verified.

In markets with benchmarking mandates, that shift is worth more than convenience. Some assets report to both the city and the state on separate deadlines, against a data quality checker that rejects any billing period longer than 30 days. Utility providers routinely bundle three months into a single read date and reissue bills with credits after the fact, so every one of those records had to be split by cost and consumption, cleaned, and re-uploaded by hand before a third-party engineer could validate the submission. That work now happens in the platform.

Equipment Monitoring

By 2024 the relationship had a track record, and the conversation moved from what Enertiv could report on to what it could improve. The owner added equipment monitoring with BMS integration at two assets, connecting equipment-level data to the platform alongside the utility data already flowing.

Enertiv modeled the operational savings opportunity at $22,000 a year. Verified savings came in at $86,012, or 3.9x the projection, with no capital investment and no facility downtime.

Some of the findings:

• Fourteen supply and return fans ramping to full speed simultaneously at morning startup
• Chilled water circulating at a 2.74°F delta-T, a signature of poor heat transfer
• Major HVAC equipment running roughly 16 hours each weekend day in buildings that are largely empty
• Mechanical cooling engaging at outdoor temperatures where it had no business running, because the outdoor air sensor feeding the BMS was reading high and the system was responding accurately to bad information

All of it was addressed through BMS control changes, without buying equipment or taking anything offline. Enertiv's engineering team worked directly with the property teams on biweekly calls, walking through each finding, agreeing on the sequence to write, and staying with it until the change was made and the savings turned up in the data. Those same calls are what kept the measures in place over the following months, since a control change that nobody revisits tends to drift back.

Other wins along the way:

• One asset reached an all-time-high Energy Star score of 94, while the other improved from 67 to 72 and moved closer to certification
• More than $200,000 in data-driven energy procurement opportunities identified
• A further $1.8M in potential savings surfaced across the portfolio, now in validation and implementation

Maintenance Management

After the results across the other modules, the owner, which had been running maintenance in a legacy system, decided to test Enertiv there too.

Bringing it into the same system changes what maintenance can see. Faults surfaced by equipment monitoring generate work orders directly, and preventive schedules get built against what the equipment is actually doing rather than a generic interval. Prior maintenance history and parts replaced sit alongside the equipment they belong to, so all of it lives in one place instead of being reconstructed from memory or from a binder.

Preventive schedules are now configured on monthly, quarterly, and semiannual cadences across the two assets, and the owner is moving off the legacy system as the platform extends across the portfolio.

One System Across the Portfolio

Every layer the owner tested came back the same way. Billing got faster and more accurate. Reporting stopped being rebuilt by hand every year. Equipment monitoring returned nearly four times what was modeled, and held. Maintenance moved into the same system as the data that drives it.

The owner is now rolling the full platform out across the rest of the portfolio in phases, adding sites as each deployment proves out. When it finishes, the entire operation runs on one system covering billing, reporting, maintenance, equipment monitoring, and capital planning, with one team accountable across all of it and one set of numbers that compares any asset against any other.

That is the part worth sitting with. The owner's results did not come from buying better software. They came from putting operations under one partner accountable for the outcome, then working each layer until it produced something measurable. For an owner, that is not a technology decision, it is NOI, capital planning built on verified conditions, and less risk carried on assumptions nobody has checked.
