For most of the history of commercial property, sellers knew more about their buildings than buyers did. Condition, performance, past problems: these were private until due diligence dug them up, and even then only partly. Information asymmetry was a source of profit for those on the right side of it.

That gap is narrowing. Across our three markets, rules increasingly require building information to be published, disclosed at transaction or reported to investors.

What is now visible

In Australia, most larger offices must disclose a NABERS Energy rating when sold or leased, and fire safety maintenance records are routinely requested. In Britain, Energy Performance Certificates are required on sale or letting and sit on a public register, and the minimum standards described in our British note turn them into a letting condition. In the United States, many cities require large buildings to benchmark energy use annually, and several publish the results; cities with performance standards publish compliance data.

Climate-related financial reporting in all three markets is bringing physical and transition risk into investor documents. And for shared buildings, reserve and inspection requirements, such as those introduced in Florida after Surfside, put capital planning on the record.

Disclosure at review

The direction is toward more disclosure, but not in a straight line, and the United States has moved backwards at federal level.

For building owners the federal retreat in the United States changes less than it seems. The building-level rules that drive capital, benchmarking and performance standards, are local, and they continue to spread.

From a number to a programme

Take a disclosed metric and ask what moves it. For an energy rating, the answer is usually a known list: controls and operation, lighting, heating and cooling plant, fabric, on-site generation. For a fire safety statement or essential safety measures record, it is the maintained condition of specific systems. For a reserve study, it is the remaining life of named components. In every case, the disclosed number is the output of physical elements that sit on a register.

An owner who holds that register can read the disclosure as a diagnosis and plan the works that change it. An owner who holds only the number can react to it. Over the next decade, as more of these numbers become public and more of them carry consequences for letting, finance and sale, the difference between those two positions will be worth a great deal.

Physical facts become price signals

When information is public, it gets priced. Tenants compare energy ratings. Lenders build them into credit terms. Buyers screen out buildings below thresholds. Insurers use condition and resilience data. What was once a technical detail discovered late becomes a visible attribute that shapes demand from the start.

Disclosure does not change a building. It changes how quickly the market notices it.

Disclosure is not a plan

Disclosure regimes publish outcomes: a rating, a benchmark, a compliance record. They do not say what to do about them, what it will cost, or in what order. A building with a poor rating has a problem everyone can see and a solution nobody has published.

That is where the advantage now lies. Owners who understand the capital path from a disclosed position to a better one, which systems, which sequence, what cost, what timing, can act before the market prices the gap against them. It’s Not About Owning Data makes the broader point: as raw information becomes more available, value moves to the ability to turn it into decisions.

Knowing first

The response that follows is to know your buildings at least as well as the market soon will: read disclosed metrics against the physical register, identify what drives each, and plan the works that would move them.

Disclosure also offers a screening layer across portfolios. It is a starting point, and the building behind each number still has to be read. Disclosure can contract as well as expand, and this note is reviewed every six months.

Questions

Does disclosure of energy ratings affect commercial property values?

It makes performance visible to tenants, lenders and buyers, which allows it to be priced. The effect depends on the market, the asset and how far the rating sits from thresholds that matter.

Is a disclosed energy rating enough to plan upgrades?

No. A rating shows an outcome. Planning requires understanding which systems and fabric drive it, what works would improve it, and in what order and at what cost.
