Chatting with RE Tech Advisors’ Deb Cloutier about data centers, lifecycle costs, and the value of federal data.

Last fall, my colleagues and I at Heatmap put together a comprehensive (and award-winning!) guide on how to Decarbonize Your Life. Though it contained information on everything from shopping for an EV to which fake meats are actually good, as my colleague Katie Brigham noted, “an energy-efficient home needs energy-efficient … gadgets to fill it up.” So we also curated lists of climate-conscious stoves, heaters, and washer-dryers — recommendations we made by talking to experts, but also by looking closely at appliances’ Energy Star certifications.
You’ve probably relied on these certifications, too. Overseen by the Environmental Protection Agency, Energy Star labels are recognized by 90% of Americans as indicating that an appliance is top of its class when it comes to saving electricity and money. According to the government’s estimates, the voluntary program has saved Americans $500 billion since it began in 1992.
But now all that appears to be reaching its end: Last week, EPA leadership told staff that the division that oversees the Energy Star efficiency certification program for home appliances will be eliminated as part of the Trump administration’s ongoing cuts and reorganization (although the president has also long pursued a vendetta against low-flow showerheads and dishwashers that “don’t work”).
To better understand the ramifications of such a decision, I spoke this week with Deb Cloutier, the president and founder of the sustainability firm RE Tech Advisors and one of the original architects of Energy Star. She provided technical guidance and tools as a consultant during the program’s development stages of the program, and later worked as a strategic advisor for the Department of Energy’s Better Buildings Initiative. Our conversation has been lightly edited and for length and clarity.
You’ve been involved in the Energy Star program since the beginning. Can you tell me a little about what the atmosphere was like when it was established back in 1992? Was there resistance to it from appliance manufacturers or Republicans at that time?
Energy Star represented a voluntary public-private partnership, meaning a nonregulatory approach to engaging the business community and catalyzing the adoption of strategic energy management. So at the time, it was the first of its kind. I wouldn’t say folks were just like, “Yes, let’s do this.” It was really new and different.
The other thing is that at that time, we had come out of the oil crisis of the 1970s, and people were starting to recognize the importance of where and how our energy was being produced. But we weren’t focused on thinking about it as an opportunity. For office buildings, the single largest controllable operating expense is your energy or utilities expenses; if the Environmental Protection Agency or the government could build awareness, develop tools, and help businesses understand how they could invest in energy efficiency and how that would translate to financial performance results for them — it was a great experiment. And it turns out that it’s the single most successful voluntary program we’ve had to date, saving over $5 billion annually.
It’s clear how losing Energy Star would harm consumers, but I’m curious to hear from you about how this is also bad for building owners and residents. What is the cost of losing this program, especially from a climate perspective?
The most important contribution of the EPA’s Energy Star program is that it has created a national standard to benchmark and measure efficiency and energy performance. You can’t manage what you don’t measure, and consistency across building types, ages, and sizes — it’s pretty complicated to make an apples-to-apples comparison.
One of the tools and resources that Energy Star has created, which I see as being embedded in the fabric of American businesses, is their benchmarking tool called Portfolio Manager. It is tied to dozens of state and local jurisdiction policies and legislation that range from building energy disclosure to mandatory best practices to maintaining and operating buildings and emissions thresholds. So the Energy Star rating system is tied not only to how organizations assess their whole building performance, but also to how it tracks and measures progress towards efficiency improvements and then gives a certification or recognition for the most highly efficient ones.
Another thing folks tend not to consider is the relationship between energy efficiency and grid stability. Energy Star-certified appliances, homes, buildings, and industrial facilities help to reduce peak demand, which improves grid stability and resilience. It also lowers the risk of brownouts and blackouts. Think about the growing demands of data center computing and AI models — we need to bring more energy onto the grid and make more space for it. People sometimes don’t realize that it is really dependent on a consistent, impartial standard as a level setting.
If you look at some of the statistics, they’re projecting that investments in new data centers will grow at more than a 20% compound annual growth rate, and that’s equal to $59 billion. It’s just astronomical how much more energy demand there will be. If you try to put that on top of a grid that is fairly antiquated and very inefficient in the way it generates, transmits, and distributes energy, then you are intensifying the potential problem.
I’ve heard about manufacturers or an outside energy or appliance group possibly setting up a replacement program if Energy Star is eliminated. What is the advantage of having the government specifically oversee Energy Star?
Three or four things make the federal government the most unique entity and the most well-equipped to oversee the Energy Star program. First, they have access to large data sets using CBECS, the Commercial Building Energy Consumption Survey, and RECS, the Residential Energy Consumption Survey. The government inherently is an impartial, unbiased group, and entities are willing to share their data with it, and that would not be the same if it were a third party or a privatized group. That data set is instrumental in creating the standards that allow you, for products, to evaluate the most energy efficient, or for buildings, to develop a one-to-100 score. Energy Star allows the top 25% to be recognized as exemplary energy performance.
The government also has access to the National Renewable Energy Laboratory resources; they have the data, and I believe they have the impartiality and the trust. Today, the Energy Star brand has over 90% consumer recognition. I would be concerned if manufacturers or others would produce confusion in the marketplace related to a single little blue label.
Is there anything consumers should know about making decisions or navigating their choices if we return to a pre-1992 landscape?
In the absence of an Energy Star label, one thing we can do is help consumers understand that it is not just about the first cost of a dishwasher or a washing machine or renting an apartment. It’s about total lifecycle costs. What the Energy Star label does is it helps you have confidence that [an appliance] will use the least amount of energy necessary to run over its lifetime. But if your product or apartment is full of less efficient appliances, you have to think about how much more energy you will pay for over that life cycle. That’s sometimes a difficult concept for folks to understand: They think of their first cost, not the cost to operate or maintain something over time, which is higher if it’s not energy efficient.
Is there anything else people often overlook when considering the ramifications of losing Energy Star?
Energy efficiency is important for all constituencies and all sectors of the U.S. economy. Some folks will be harder hit by this, and by that, I mean low-income housing, schools, hospitals, and public sector buildings. Those facilities often have very limited budgets, so energy efficiency is one of the lowest-cost, most effective investments with good returns. But if you’re a low-income family, think about it: If you make less than $33,000 a year for a family of four, your utility bills have an outsized impact on the total cost of living. If the total utility bill is $300 or $400 a month, then utilities represent 10% to 15% of your total income, so efficiency can have an outsized impact.
The other side of that is mission-critical facilities. Having the ability to run lights, air conditioning, and cooling is important for comfort, but in some facilities — like precision manufacturing or biopharmaceuticals, data centers, things of that nature — it becomes a mission-critical area, not a nice-to-have. We can help reduce the amount of energy used by those facilities, extend their useful life, help them maintain their systems longer, and allow those businesses to be more competitive.
What’s your read on how the proposed Energy Star elimination is being discussed right now?
There’s a lot of hyperbole about Energy Star being eliminated — it’s a fait accompli. It is important to note that Energy Star is a line item identified in the statute by Congress for approval for funding. It seems pretty unrealistic, from a judicial standpoint, that it would be able to be eliminated before the end of this fiscal year.
I know that there are many, many representatives, both Republican and Democrats, who support Energy Star. We’ve had 35 years of bipartisan support, and it has been earmarked in congressional law many times, through multiple George H.W. and George W. Bush administrations. And there are a lot of lobbying efforts that I’m personally aware of within the commercial real estate industry and the manufacturing industry, where folks are reaching out and doing calls to action for the House and Senate Appropriations majority members — similar activities to what we did eight years ago when Energy Star was directly under fire.
It seems like such a strange thing for the administration to go after. It’s not like appliance manufacturers were clamoring for this, right?
It’s very vexing to me. I don’t get it. If the Trump administration wants to focus on affordability in American households, energy efficiency isn’t the thing to cut. I’m not sure if it’s getting caught up in the fact that it is in the Office of Atmospheric Pollution Prevention, or because at the Department of Energy’s Better Buildings Program, Biden launched the Better Climate Challenge. I don’t know if it’s because it had some ties to climate, but what’s ironic is that it didn’t start as a climate program. It began as an energy efficiency program, and it’s always been focused on businesses and the financial returns on investment — it helps us attract capital and debt for investment in real estate. It’s really disconnected.

Climate tech investors talk investing in moonshots at SF Climate Week.
Three climate investors walked onto a boat.
That’s not the start of a joke — it’s a description of a panel at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week (at the Klamath, a venue made out of an old ship).
Heatmap’s Katie Brigham moderated the roundtable conversation with Prelude Ventures Managing Director Gabriel Kra, Azolla Ventures co-founder Matthew Nordan, and Toba Capital Partner Susan Su. Many of their investments are in moonshot climate technologies that other financial players might avoid.
“Things that look contrarian is kind of what we do,” said Kra. “Occasionally, there’s an idea that looks bad that’s actually a good idea.”
Prelude Ventures funds early-stage climate companies that are “weird, or non-consensus, or counter cyclical, or just ahead of the curve,” according to Kra.
Nordan, for instance, said he backs cultivated meat despite some doubts that the category will achieve widespread popularity.
“I’m presently leading an investment in a company called Pythag Technologies,” said Nordan, talking about the generative AI company focused on lab-grown meat. “It’s actually a really interesting time to invest counter-cyclically in a field like that.”
Like Nordan, Su described her firm as one that is open to unconventional choices.
“We are very weird in that we invest across lots of different categories and lots of different stages,” said Su.
One of her personal investments is in Xeno. “This company does electric motorbikes for commercial drivers, as well as swapping and energy networks in emerging markets, starting in East Africa,” she explained.
The panelists told Katie that opting for less popular investments can be rewarding because they may help fund a major breakthrough.
“We placed a couple of bets on fusion before this current melée occurred that sort of had everybody thinking that, you know, fusion was the next hot thing,” said Kra (who claimed that he intended the pun).
Nordan emphasized the gap that venture can fill, left by larger institutional investors who may shy away from high-risk technologies.
“If there are true breakthroughs out there that just may not be investable by mainstream finance at the earliest stages,” Nordan said, “not because people don’t think they’re really good ideas, but they may be crazy early-stage or kind of weird, or non-consensus, or counter-cyclical, or just ahead of the curve, it would be a real shame.”
Noise ordinances won’t necessarily stop a multi-resonant whine from permeating the area.
What did you do for Earth Day this year? I spent mine visiting a notoriously loud artificial intelligence campus in Virginia’s Data Center Alley. The experience brought home to me just how big a problem noise can be for the communities adjacent to these tech campuses – and how much further local officials have to go in learning how to deal with them.
The morning of April 22, I jumped into a Toyota Highlander and drove it out to the Vantage VA2 data center campus in Sterling, Virginia, smack dab in the middle of a large residential community. The sensation when I got out of the car was unignorable – imagine an all-encompassing, monotonous whoosh accompanied by a low rumble you can feel in your body. It sounds like a jet engine that never stops running or a household vacuum amplified to 11 running at all hours. It was rainy the day I visited and planes from nearby Dulles International Airport were soaring overhead, but neither sound could remotely eclipse the thudding, multi-resonant hum.
If you want to hear the sound for yourself, this video accurately sums it up.
After parking nearby I walked to one of the residential enclaves adjacent to VA2. One resident of a home across the street, who declined to give me her name, said she moved there before the project was completed. When asked how she felt about the noise, she told me, “It’s not as bad as it could be on the other side [of the data center], where all the equipment is.” (While the sound does get louder on the other side, I could clearly hear VA2 from her driveway.)
VA2’s noise has been causing problems for months, as documented by numerous social media posts, local news clips, and a feature published in Politico. It’s doubtful many of those living near the data center wanted it there. The project was built quite quickly – so quickly that Google Earth still shows undeveloped woodlands on the site. Per public filings, Vantage first proposed the facility in 2022 under the county’s fast-track commercial incentive program, an expedited permitting process for specific preferred industries. It was under construction as recently as October 2024, according to images captured by Google Street View.
Noise is one of the most common issues associated with data centers. At least a third of all conflicts over data centers are over noise complaints, and noise is the number one reason for opposition in cases where projects were ultimately canceled, according to Heatmap Pro data.
This issue goes back almost a decade. In 2019, residents of the Phoenix ex-urb Chandler, Arizona, became irate after a loud monotonous hmmmm began emanating from a CyrusOne data center. In that case, CyrusOne traced the noise back to chilling fans, and the company reduced the sound with muffling devices.
Chandler wound up adopting a new ordinance in 2023 requiring sound mitigation measures to prevent companies from exceeding certain ambient noise levels in the surrounding areas. That did nothing to improve the mood of the people who live there, however. Now Chandler, once known as a potential data center development hub, is now firmly in the anti- camp. The city council unanimously rejected a proposed $2.5 billion data center campus in December over noise concerns, despite an expensive lobbying push backed by former Arizona Senator Kyrsten Sinema.
As data centers spread across the U.S., noise is becoming an ever-more-common complaint. You can hear the familiar hum at a DataOne data center project in Vineland, New Jersey. DataOne told us they “understand concerns about ambient noise in the area” and are operating within the limits of local noise ordinances.
The hum is also in Dowegiac, Michigan, where people living nearby are calling their new Hyperscale Data facility a “noise trap,” with little explanation to date for the issue. Hyperscale Data did not respond to a request for comment.
And the hum is in Mount Pleasant, Wisconsin, where the sound from a new Microsoft data center campus rises above any din from rain. The hyperscaling giant is doing more to mitigate the issue than I’m used to seeing from data center developers, however.
On April 15, the company published an update on its own internal investigations into noise complaints. “Although the facility noise levels meet the requirements set by local ordinance, we take this feedback seriously and understand the impact this has had on our neighbors,” the update read. “We anticipated that our systems would need adjustments and create some noise as part of the datacenter startup, but we did not expect the tonal quality of the sound to travel as far as it has.”
To address the noise, Microsoft said it was “manually adjusting the cooling fans” to reduce noise, and that “we expect this change to address community concerns about the tonal humming.” On top of that, the company said it will install “additional sound reduction components” to “provide even further reductions in measured sound levels.” A Microsoft spokesperson told me in an email: “We’ve identified the source of the noise concerns and have implemented changes to significantly reduce sound from our facility.”
It isn’t cooling fans causing the noise at Vantage’s VA2 in Virginia, however. The sound, according to media reports, is coming from gas turbines powering the data center.
VA2 is one of the first in Virginia to function entirely off-grid, a design companies are adopting in order to avoid lengthy grid connection processes. Company spokesman Mark Freeman told me the facility is “fully compliant with all local noise ordinances, and this has been verified by third-party sound studies.”
“Additionally, in line with our commitment, we are actively working with third-party engineers to explore additional sound mitigation options,” Freeman continued. Freeman said “Our goal is to further reduce noise levels where possible and continue to foster a positive environment for everyone.”
Here’s the thing, though: I visited the Vantage campus after initially hearing from the company, and it was loud. Very loud.
I did not bring a decibel meter with me, so I cannot know whether they were operating within legal limits that day. What I do know is that noise ordinances struggle to properly capture sounds in multiple frequency ranges, making high and low frequencies challenging to regulate, according to the Environmental and Energy Study Institute, a bipartisan non-profit think tank. Officials representing Loudon County, where VA2 is located, have acknowledged that the local ordinance may need to change in order to address the most distressing frequencies from the data center campus.
“We can change the zoning ordinance and noise ordinance,” Loudon County supervisor Mike Turner told local TV station WUSA9 last week. “Noise can be mitigated. I just don’t believe that the noise problem cannot be solved.”
I wrote Freeman, the Vantage spokesman, to tell him I had visited the VA2 campus and found the noise to be “quite foul.” He replied soon after, telling me that Vantage is going “above and beyond what is required in order to address concerns from nearby residents.” The company is using “targeted enhancements to turbine-related equipment such as dampening equipment, enclosure inlets and enclosure exhausts.” These measures “represent meaningful progress and will help us better evaluate the effectiveness of the broader solutions under consideration.” Freeman also said the company is “actively assessing additional options” focused on “targeted frequency ranges.”
As we continue to track local regulation of data centers, I’m we’ll see many more cases like VA2, in which obtrusive sound prompts forms of regulation we may have never seen before.
Or, people will just hear these noises and say no to more data centers.
Plus more of the week’s biggest project development fights.
