What Good ESG-Oriented Commercial Real Estate Actually Looks Like: David Rocker on the Signs That Separate Substance from Marketing
23 Sept 2026
A term that gets used loosely
ESG has become a label almost any commercial real estate deal can wear. A property with a recycling program and a solar panel on the roof gets pitched the same way as one built around real energy performance and long-term operating savings. Investors are left to guess which is which.
David Rocker, managing partner of NYSA Capital LLC, works in commercial real estate finance and capital markets, structuring deals across the Sun Belt where ESG claims show up constantly in pitch materials. His view is that ESG only matters if it changes the numbers on the deal. If it does not show up in the underwriting, it is decoration.
The test: does it change the pro forma
The simplest way to tell real ESG work from marketing is to ask what line item it touches. Good ESG-oriented real estate changes operating costs, insurance terms, tenant demand, or exit value. It shows up somewhere concrete.
Signs of substance:
- Utility costs that are actually lower, with data from a comparable property or a prior phase
- Insurance premiums that reflect resilience upgrades, not just a mention of them
- Water or energy systems sized to reduce a specific recurring cost, not just installed for appearance
- Tenant retention or lease-up speed that is faster than the market average, tied to a stated reason
Signs of marketing:
- Certifications listed without any tie to operating performance
- ESG language in an offering memorandum with no adjustment to the underwriting model
- Vague claims about “sustainability” with no baseline to measure against
Rocker’s approach treats ESG as an underwriting input, not a chapter in a brochure. If a green feature cannot be tied to a number, it does not belong in the deal thesis.
Where the Sun Belt makes this easier to check
Sun Belt markets give investors an advantage here that older, denser markets do not always offer. Newer construction means there is often a direct comparison available: an older phase of the same project, or a comparable property built five or ten years earlier without the same upgrades. That comparison is where the real evidence lives.
An investor evaluating a build with better insulation, more efficient HVAC, or water-conscious landscaping should ask for the utility bills from a comparable unit or building nearby. If the sponsor cannot produce that comparison, the ESG claim is untested. This is a low-cost check that most investors skip, not because it is hard, but because the marketing materials make it feel unnecessary.
What good looks like at the fund level
For an investor allocating to a fund rather than a single deal, the same logic applies at a larger scale. A fund with a real ESG discipline can usually answer three questions clearly:
What is actually being measured. Energy use, water use, and resilience to climate-related risk are measurable. “Community impact” without a metric attached is not.
How it affects underwriting. A fund that treats ESG seriously will show how it changes assumptions on operating expense, insurance, or exit cap rate. A fund that does not will describe ESG separately from the return model, as an add-on rather than an input.
What happens when ESG and return trade off. Every real deal has moments where the lower-cost option and the more sustainable option are different choices. A fund with a real position on this will say which one wins and why. A fund without one will avoid the question.
A step investors skip
The step most often skipped is asking for the baseline. Sponsors are usually ready to talk about the upgrade. They are less often ready with the number it is being compared against. Without a baseline, a claim like “20 percent more efficient” has no anchor. Twenty percent of what, measured how, against which comparable?
Investors who ask for the baseline before asking about the upgrade get a much faster read on whether the ESG story holds up. It also tends to reveal, quickly, whether the sponsor has actually tracked the numbers or is repeating language from a broker.
A short checklist
Before treating an ESG claim as part of the investment thesis, it is worth running through a short list:
- Is there a comparable baseline, and has it been shared, not just referenced?
- Does the ESG feature change a specific line item in the underwriting?
- Is the claim measured in real units (kilowatt hours, gallons, dollars) or in adjectives?
- Would the deal still make sense without the ESG framing?
That last question is the one that matters most. If a deal only works because of how it is described, rather than how it performs, the description is doing work the property is not.
Rocker’s position is that this is not a special standard for ESG. It is the same standard any underwriting item should meet. The difference is that ESG claims are newer, less standardized, and easier to dress up without anyone checking the math. Investors who ask for the number instead of the language tend to get a much clearer picture of what they are actually buying.
