You can usually name your best building without pulling a report. Requests get handled fast. Vendors show up prepared. The mechanical rooms look orderly. Your team knows what to do when something goes wrong, and the building feels easier for tenants to live in and work in.
Then there is the other building. The one that seems to generate emergencies out of thin air. The one where small issues turn into big ones, and where your team spends too much time chasing the same problems. That difference is your operational gap.
The gap is not just stressful. It can become a material cost problem. Energy is a big line item for commercial buildings, and at a national level the U.S. Energy Information Administration[1] reports that U.S. commercial buildings spent about $141 billion on energy in 2018. [2] Across a portfolio, even modest differences in schedules, controls, and upkeep can add up across square footage, months, and years.
You can also see that buildings can improve when operations improve. The Commercial Buildings Energy Consumption Survey highlights that commercial buildings overall used less energy per square foot in 2018 than in 2012. [3] The biggest upside often sits where you focus the most attention. In that same survey summary, buildings over 100,000 square feet were only 2% of buildings, yet they accounted for 39% of total energy consumption. [4] When a large building runs poorly, the money leak is bigger. When a large building runs well, the savings and stability can be bigger too.
The operational gap rarely sits in a single, obvious failure. It hides in dozens of small decisions that repeat every day. One site has tight start and stop schedules for heating, cooling, and lights. Another runs longer than it needs to, or drifts over time because setpoints get changed during a complaint and never get set back. One site has clear rules for how fast issues get acknowledged and resolved. Another has a backlog that grows because everything feels urgent and nothing feels planned.
Maintenance strategy is one of the cleanest dividers. In its Operations and Maintenance Best Practices Guide, the U.S. Department of Energy[5] shows a referenced breakdown where more than 55% of maintenance resources and activities in an average facility were still reactive, with smaller shares devoted to preventive maintenance. That matters because reactive work tends to bring unplanned downtime, overtime, and more costly repairs, and it can shorten equipment life when systems are run to failure instead of maintained on purpose. [6]
Risk exposure is another place the gap shows up fast. Water and escaped liquids are a strong example because the outcomes can be sudden and expensive. FM[7] reports that liquid damage was responsible for 58% of losses in finished facilities in its data from 2012 through 2022. [8] It also frames liquid damage as more likely to cause loss than fire and more likely than many natural hazards. [9] That is a useful reminder that “small” building risks can be frequent and disruptive.
If your worst building is the one with the most leak surprises, treat that as an operations gap, not bad luck. Walk high risk areas on a schedule. Open and close key valves so they work when you need them. Put leak detection in places where liquids collect or where piping runs near critical equipment. [9] Even simple steps like these can reduce the odds that a hidden leak turns into a major event.
Tenant experience is where all of this becomes real. Tenants do not care whether a task was labeled preventive or reactive. They care about whether the dock door works, whether the temperature is stable, whether the elevators are reliable, and whether communication is clear when something breaks. When your best building makes those moments smooth and your worst building makes them chaotic, you are paying a hidden tax in renewals, referrals, and reputation.
You do not need a perfect financial model to see the size of the problem. You need a simple approach that is directionally right and easy to repeat. Start with electricity, since it is widely used and measured cleanly. In the CBECS tables, the distribution of site electricity use intensity for all buildings that used electricity shows a 25th percentile of 3.8 kilowatt hours per square foot, a median of 8.7, and a 75th percentile of 17.2. [10] The point is not that every building should hit the 25th percentile. The point is that a wide spread exists, and your portfolio likely has its own spread too.
Now put simple numbers to it as a reality check. If two similar buildings in your portfolio are far apart, and the gap looks like the difference between 17.2 and 3.8 kilowatt hours per square foot, that is 13.4 kilowatt hours per square foot of swing. [10] On a 500,000 square foot building, that is about 6.7 million kilowatt hours per year. Using the national average commercial electricity price for 2025 of 13.41 cents per kilowatt hour, that electricity gap alone comes out close to $900,000 per year. [11]
Where the “millions” show up is the portfolio math. If you have several large sites, and even a few are operating far from your best building, you can carry multiple six figure gaps at the same time. Add in natural gas, add in reactive repairs, add in after hours labor, and add in the cost of damage events. The total can move from “annoying” to “big enough to change your budget plan.”
The good news is that you do not always need big capital projects to capture value. An operations and maintenance guide developed under the Federal Energy Management Program[12] highlights that O and M programs targeting energy efficiency are estimated to save 5% to 20% on energy bills without a significant capital investment. [13] That range gives you a practical way to think about potential upside before you spend a dollar on new equipment.
One of the most repeatable ways to close the gap is commissioning, which is a structured check up that finds issues in how a building is actually running. In a large analysis of commissioning project outcomes, Lawrence Berkeley National Laboratory[14] reported median whole building energy savings of about 6% for existing building commissioning in the more recent data set it analyzed, with a typical range from the 25th percentile to the 75th percentile of about 3.4% to 12.4%. [15] That same analysis reported a median project cost around $0.26 per square foot for existing building commissioning in its combined data set. [16] If one building in your portfolio is drifting away from your standard, commissioning can be a targeted way to bring it back in line.
The fastest way to shrink the gap is to stop guessing which buildings are healthy. You can do that with a small scorecard that is consistent across every site. It should be simple enough to update monthly, and strict enough that it keeps conversations grounded in facts. You are not building a research project. You are building a tool that helps you spend time and budget where it matters.
A useful scorecard usually has three layers. The first is reliability. Track preventive maintenance completion rate, repeat work orders on the same asset, emergency calls after hours, and downtime on systems that disrupt operations. The second is cost control. Track total maintenance spend per square foot, overtime hours, and how often vendor work turns into change orders. The third is responsiveness. Track time to acknowledge a request, time to close, and the share of tickets that require more than one visit.
Once you have the scorecard, use it to compare buildings that should behave similarly. Compare like with like, such as one warehouse to another warehouse or one suburban office to another suburban office. Then look for drivers, not blame. When one building is always worse, it is often a process gap, a staffing coverage gap, an asset condition gap, or a vendor network gap. Your scorecard helps you see which one it is so you can act with confidence.
If you want a simple starting point, run a two week baseline. In week one, capture what you already have: utility bills, work order counts, overtime hours, and your list of critical assets. In week two, add one consistent operational walk at each site. Check for basic signals: are schedules clear, are filters and belts on a real cadence, are shutdown procedures posted, and are recurring issues documented with a cause, not just a quick fix. A consistent baseline beats a one time deep dive that never repeats.
Your best building is your blueprint. The goal is not to make every building identical. The goal is to make your operating system consistent so the basics get done well everywhere. Start by documenting what the best building does that the worst building does not. Focus on what is repeatable: how work is triaged, how vendors are dispatched, how preventive maintenance is planned, and how decisions are communicated.
Then convert those habits into a short playbook. Keep it concrete and short enough that people will actually use it. Write down what happens in the first hour after a critical issue is reported. Define when a problem gets escalated. Define what information must be captured before a vendor is called. Define what a good closeout looks like, including photos, notes, and the cause of the failure. The payoff is fewer repeat visits and fewer surprises.
Use the playbook to shift the mix of reactive versus planned work. The DOE guide describes preventive maintenance as actions performed on a schedule that detect or mitigate degradation, and it cites estimated 12% to 18% cost savings over a reactive maintenance program. [17] The same guide describes predictive maintenance as condition based maintenance and lists estimated 8% to 12% cost savings over a preventive maintenance program. [18] You do not have to change everything at once to benefit. Pick a small set of critical assets, tighten the preventive cadence, and add basic condition checks where they make sense.
You can also close the gap faster by standardizing vendor scope, not just vendor names. When one building gets a tight scope with photos and clear acceptance criteria, and another gets a vague call that starts with “it is not working,” you invite inconsistent outcomes and pricing. A basic scope template helps: symptom, location, recent history, access instructions, safety requirements, deliverables, and a clear definition of done. Your best building likely already does some version of this. Your worst building probably does not.
Even if you never run a formal tenant survey, you still live in a satisfaction economy. Tenants notice how fast you respond, how clean and safe the building feels, and whether recurring issues come back month after month. Those experiences show up later as renewal friction, concessions, and the reputation that follows a property.
You also have research support for the idea that satisfaction links to leasing decisions. A large study funded by the Real Estate Research Institute[19] reported that a one point higher overall tenant satisfaction score on a one to five scale was associated with an 8.36% higher willingness to renew, an 11.52% higher likelihood to recommend the property, and a 15.80% lower probability of moving out. [20] In plain terms, smoother operations are not just a service goal. They can protect occupancy and reduce churn risk.
You do not need to chase perfection to benefit from this. You need consistency on the moments that matter most. If you make response times predictable, close the loop clearly, and reduce repeat failures, you create a calmer tenant experience. That calmer experience supports renewals, and renewals protect cash flow. When your building is competing against similar space nearby, operational consistency can be the difference between a quiet renewal and a costly reset.
If you want a practical next step, pick one building that represents your “best” and one that represents your “worst.” Run the same scorecard for both for one month. Then do a focused gap review with your team using three questions. What does the best building do every week that the worst one does not. Which two processes would reduce the most repeat pain if they were consistent. What asset or risk item could create the biggest surprise if it fails. Your answers will give you an operations plan you can act on right away.
Closing that gap gets much easier when your operations, data, and workflows live in one place instead of being scattered across systems and spreadsheets. That is where Cove comes in. Cove brings building operations, work orders, preventive maintenance, and portfolio reporting into a single platform so your team can standardize how work gets done across every property. Instead of relying on memory or inconsistent processes, you create a repeatable system that makes your best building the baseline. And because Cove continues to evolve alongside your team, you are not just fixing today’s gaps. You are building a more consistent, efficient portfolio over time.
