Chad:I am Chad Reed.
Hilary:I'm Hilary Langer.
Gil:I'm Gil Jenkins.
Guy: I'm Guy Van Sickle.
Chad: And this is climate positive.
Marshall: 80% of the buildings in New York City are heated by steam heat radiators. And of the emissions that the city generates, I believe the majority is from space heating. If you think about it, you know what other fuel is consumed? Combusted in New York City, it's cars and it's buildings heating.
Gil: Today on Climate Positive, I’m joined by Marshall Cox, the founder and CEO of Kelvin—a company turning century-old radiators into smart, energy-saving machines. I hope you enjoy the conversation, and as always, we appreciate you leaving a review and rating wherever you get your podcasts.
Gil: Marshall, welcome to Climate Positive.
Marshall: Thanks. It's great to be here.
Gil: So maybe to start, can you share the story behind the founding of Kelvin, formerly Radiator Labs in 2013? Uh, and you have to tell the, uh, inspiration as it relates to your twin brother who was visiting you, um, at your apartment in New York.
And, and then from there we'll get into the, where Kelvin is today, where you're going. But let's start with the origin story.
Yeah, sure. No worries. So the, the company actually, the early days was actually 2011. 2011, okay. Yeah. My, my, uh, I have a twin brother who's a. Now retired professional ballet dancer. He is actually relatively famous, was a presidential scholar of the arts.
He like went and shook Bill Clinton's hand on stage. And then he was a professional dancer for like 10 years in Miami State Ballet. And then he wanted to quit that before he got too old to do anything physical. And so he got into a, a big Broadway show. He was a principal dancer in this new thar show in New York.
And he moved to the city with me. Well, I was at Columbia and so he moved into my, my dorm room. 'cause didn't, you never know how long those shows are gonna last. He slept on my floor and um. The heat in the winter was so bad he was next to the window, so it like, it would get super, super hot and then he'd open a window and then it'd get super, super cold.
And he was super unhappy and he was very vocal about that. He let it
be known to his twin brother. Yes. I imagine, you know the dynamics, double dynamics brother twin an artist. Oh yeah.
Marshall: It was very clear that he was not happy about it. And so kind of as a side project I, I like it was very annoying to me, so I shared that annoyance with my.
PhD group and my advisor who urged me to do something about it. So I built this kind of little bubble wrap thing with a computer fan and Arduino and controlled the temperature and it worked really freaking well. And so I, I took that data to Columbia facilities and they were interested in trying it out, and that was.
The beginning. So I, I built the first, I learned how to sew. I built these like fabric weird covers and installed 'em in a building in at Columbia. And it didn't work well at all. But, um, I got some really good data. And then we won a big prize from the MIT Clean Energy Prize. We won the grand prize in 2012, and that was about a quarter million dollars.
And we used that to develop a first real system. Wow. And we installed in a larger building and it worked super well that gained the entrance of nyserda and then everything kind of. Snowballs.
Gil: So you're like,
I'm an, I'm an entrepreneur now. You know, I'm not, I'm no longer in the labs. Yeah. Solved a problem.
And, and fast forward to today. So Kelvin, and let's get into the flagship product, the cozy, um, many ways it's an insulated radiator cover, but it's a whole lot more.
Marshall: Yeah, so the company's mission has always been the same. I always felt that, you know, I, I was not sure before this company too, not, not to the same level of, of course, but the market that.
I perceived an overheating in New York. Seemed like the biggest, I'm an environmentalist through and through my PhD was in organic solar cells. Wow. And the amount of energy that I thought could be mitigated through efficiency in these buildings in New York City was more than I could ever hope to have an impact in any other field.
Gil: And once the stat there, it's like 80% of. Buildings are, are steam. About
Marshall: 80% of the buildings in New York City are heated by steam heat radiators. And of the emissions that the city generates, I believe the majority is from space heating. If you think about it, you know what other fuel is consumed?
Combusted in New York City, it's cars and it's buildings heating, you know, power plants are not in the city. So those, the emissions are from these buildings. And obviously when you have. A huge building in the middle of February with all of its windows open.
Gil: Um, you're deeply inefficient.
Marshall: It's extraordinarily inefficient.
I, I'm pretty sure this is a safe thing to say that single pipe radiator steam buildings are the least efficient buildings on the planet.
Gil: Yeah. But you gotta, you know, on some level, the amazing, you're engineer, right? I mean, these were. Built, they're lasting. So we have the technology now.
Marshall: So no, these
buildings were built to last, right?
Yeah. Like these things are 100 years old, often and often a lot more than that too. They're, uh, awesome. And as we talk later on about, you know, our electrification plans, I can they kind of build
Gil: Yeah. I
wanna get into, I certainly wanna get into that, but like, paint a picture of the Cozy Smart radiator cover.
Marshall: Yeah, so greater heated buildings, steam and hot water, you know, water or steam courses to the building and heats up radiators at different amounts depending on how close they are or how, how fast the air vents out of 'em. And so you get really hot radiators across the building at different times, rooms that need different amounts of heat.
And so you, you can imagine for those people with, with sciencey backgrounds out there, but Gaussian distribution. A normal distribution of temperatures for a building. A lot of apartments are hot, a lot of apartments are cold. There's some that are right there in the middle. Unfortunately, or fortunately, in most cities, there are statutory minimum temperatures that if the building does not provide enough heat to those apartments, they don't have to pay rent, and that that number is 68 degrees Fahrenheit.
And so if any apartments are under 68 degrees Fahrenheit in a big rental building like you have, like most these buildings are, those persons don't pay rent. And as you can imagine, the people who run those buildings do not let that happen. And so the bell curve is shifted dramatically up so that the lower curve is always above 68 degrees.
And so everybody else is dramatically overheated. There's people whose apartments, if their windows were closed, would be 95 degrees Fahrenheit. It's um, it's outrageous. And so what the cozy does. Is, it is a smart radiator cover that goes on most of the radiators in the building. It measures the radiator temperature and the room temperature.
And if the room is over the set point temperature, the fan doesn't turn on and it blocks heat from coming outta the room. Doesn't let hot air convec out it, it's insulating, and so the room gets cooler, and then if the room cools down below the set point, the fan turns on and blows that heat back onto the room.
And so when you stop heat from escaping from a radiator to unnecessarily overheat one apartment. Since the STEAM system or the hot water system is just one system, that energy can actually flow to different apartments. And so we almost literally push heat from hot apartments to cold apartments and make that bell curve, that distribution much, much tighter so that most of the apartments now are around the 70, 72 degree range, and very few are above the 75 degree range.
And so you, you eliminate. Essentially 25 to 40% of heating costs and fuel consumption as a result.
Gil: Fantastic. And I wanna come back to the carbon story as we get into the broader implications, but
what's install like? Super easy, right?
Marshall: Super easy. So one of the nice things about what we do, you know, the hardest part about what we do and, and the hardest part of any company doing anything in UN like this, people's homes and multifamily is getting access.
So you wanna minimize the time you're in there. You want to be as fast as possible and you want to use the most widely available labor possible. So the cozy doesn't have anything to do with plumbing, right? We don't need a plumber, we don't need cut any pipes. You don't wanna be cutting a hundred year old pipes.
Um, so this thing just plops right on top and then plugs into a wall. So we don't need any licensed labor. There are thousands of companies that would love to install this and have the, you know, more than enough expertise to do it. And we either survey a room where we know what size Raiders are. We build them, we deliver them, someone walks in, drops it, plugs it in and walks out.
It's really, really easy.
Gil: And these have to be somewhat custom though. How many of these have you installed since 11?
Marshall: We've installed about, I'd say 20,000. 20,000 to date.
Gil: Wow. And is there somewhat a uniformity in, in these No. Radiators? There's not that we're, uh, that's, yeah.
Marshall: So some buildings do. There's campus buildings that like, have maybe three different sizes and those are really easy.
We go in, we just build a lot of these sizes and, and deploy them where they're needed. Um, some buildings have gone through, you know, 60 years of people complaining it's too hot and a radio being removed and a smaller one being put in. So universities are a good example of, of the trying to like balance it themselves.
The brute force solution is that we go into these buildings and we survey everything and we build them custom and we deliver them and that. Economically works. You know, like the survey step is another site visit and that's a little painful, but the fact that we can arrive with the exact right cover solves a lot of issues in the install side.
Gil: Oh, it's pretty common for all home energy efficiency, obviously. I mean, that's a standard step.
Marshall: Totally.
That being said, we are developing a modular cover and that's ready. We're, we're gonna make our first big order of that. And this is a system that can adapt to different radiator sizes and, and, you know, you'll need to know that most of the Raiders are the right size, but you should cover about 80% of the radiators out there, just with kind of one or two skews.
And so we'll inventory that and then we'll cut off a significant portion of the, the lead time because we don't have the custom manufacturer anymore.
Gil: Right. So you mentioned the, um, the energy and cost savings. Let's talk about the financing. Right. You offer is zero money down. You know, it's sort of like.
Pays for itself, or a couple years talk, talk about the go to market model and the, and the financing options for,
Marshall: so over the past many years, if we learned anything, we've learned that people don't wanna spend money.
Gil: Indeed.
Marshall: And it's, it's obvious, right? Like even, you know, the people who run these buildings, they're, they're humans.
They're just like you and me. They have feelings about the environment, et cetera, blah, blah, blah. But the bottom line is that these buildings are businesses. They can't do anything if it doesn't make financial sense. And so, um, you know, there's a whole slew of the market that doesn't have access to capital at all and can't spend money even if they wanted to.
And then there's, there's people for which it has to make economic sense for them to vote to do it. So overarchingly what we launched, by the way we responded to this need is we launched last year, a subscription plan. We talked to and worked out a deal with a company called Clear Gen that that works with Blackstone to fund deployments based on contracted subscriptions.
And so we go to buildings now and we say, Hey, this is your energy. I. You know, we we're very good at calculating what their loss is and how much we'll save. We say, this is your, how much, so much you'll save a year. This is the subscription cost. It's between 10 and $20 per apartment per year, and it's almost always less than the, the amount of money they'll save.
And so we'll contract with them for 10 or 15 years. Clear Gen will give us the money to deploy it, we'll deploy it for free, and then we'll start charging once in an operation. And it's an instant ROI, no upfront cash. And they're saving more than they're spending every year.
Gil: And talk about in New York.
We're gonna walk out a bit on policy, something called Local Law 97, which I'm somewhat familiar with. But give an overview of what local law 97 is in New York, what the measures are to compel building owners to take another look at efficiency solutions and where you fit in there.
Marshall: Local on a seven is the law aiming at increasing the efficiency of buildings in New York City. You know, again, with the lens that most of the emissions come from building heating. So what it makes buildings do, depending on what kind of building you are, is calculate your energy use in something called a.
EUI, energy use intensity, your energy use per square foot. And depending on where you are on a scale, it'll say this is what your limit is. You can't emit more than this. If you're admitting more than this, you're gonna get fined a dollar amount per ton of carbon that you emit. And for some buildings that's extraordinarily high fines.
Now whether the city actually fines buildings or not is. Actually a question mark because they do not want to penalize their, you know, co-ops, right? They just want, they wanna help them get to a place where they're more efficient. But what it definitely does is it has increased the visibility of this for all the buildings in New York City, right?
If you need to be compliant with this law, you have looked into it and figured out, you know, how much your building emits. And so in light of that. There's a lot of people who say, look, only seven is terrible because it's just making us spend all this money. It's way too expensive. No one can ever be compliant.
And Kelvin has come out, especially with this subscription plan and said, Hey, it doesn't have to cost you a lot of money. It doesn't cost you any money to be compliant. Right. We're here to savings or, or within Exactly right. Like the savings will pay for the technology implementation, whether it's the cozy or hybrid electrification, which we're talking about in a second.
Everything we design is built around that basic premise. It has to make economic sense for people to do it.
Gil: Why don't you talk about hybrid electrification? And you know, clearly the movement in building decarb is electrification. I'm kind of amazed over the last few years about the sort of heat pump.
I'll refer to it lovingly as a religion. And heat pumps are great, but you guys are probably working on a heat pump. But electrification is a journey, right? And there's things you do. And the goal is, is emissions along the way, and we don't wanna be cost prohibitive. That's not gonna be the uptake. I'll get off my soapbox, but I heard you talk about your approach.
Maybe you could break that down. How Cozy integrates with and what Kelvin's doing on broader. Building electrification trends.
Marshall: Yeah, totally.
So first of all, we are not building our own heat pump because there are plenty of people doing that. So our, our goal is to implement heat pumps in a way that's, we call it resource efficient decarbonization.
So kind of take a quick red, I like it. That's right. So take a quick step back. If you were to guess how many buildings New York City of our target market. Have electrified, what would you guess?
Gil: It's a pretty low number, right?
Marshall: It's an extraordinary low number. It's less than 1%.
It's actually, I think it's less than a dozen. Maybe it's, maybe it's more like two dozen now. Anyway, it's a drop in the bucket and New York City is one of the markets where you think like there's the most pressure, like in the world, maybe, certainly in the United States, to electrify. And the reason why it hasn't happened is because the electrification scenario for a large multifamily radiator, heated building is outrageously expensive.
It's 'cause there's no duct work that you can tie into. You have to, you know, either blast a hole through the wall or run refrigerator lines throughout the entire building. It's really, really expensive. There's some new companies out there that are great, that are building window cold, climate heat pumps, and these are really fantastic pieces of technology, but they're really expensive.
And the unfortunate thing is that you electrify your building. Most of the costs that you bear are when it's really cold out. Because the systems are less efficient when it's really cold out and they consume more electricity per unit of heat. They, they produce, um, and they need to go full blast during those, those colder winter snaps.
So the price of heating for full electrification is actually a lot higher than the price of heating from natural gas. No surprise. Natural gas is cheap. What we are doing is we are saying, look, these radiator systems are there. They're gonna die at some point. The boiler's gonna die, but it's not gonna be for 10, 15 years.
And let's not wait until that happens, but let's deploy a heat pump solution that works in conjunction with that boiler system while we can. And so hyper electrification is the idea of deploying window form factor heat pumps just a simple swap out of your existing air conditioner and run those when weather permits ie above freezing. And then when it gets really cold out, turn the steam system back on, or the hot water system. And so what that allows you to do is heat above 32 Fahrenheit, which is, it's about 70% of the BTU you need for heating in the winter. So you can do 70% decarbonization with a extraordinarily cost-effective window heat pump, which costs kind of the same order as an air conditioner.
And then that cost of heating is lower than the cost of natural gas heating 'cause window. Those heat pumps are, are very efficient at those higher temperatures. And then when it gets really cold out using the steam system on that's natural gas, like normal, you're using a system you're familiar with. So overall, we can do about 70% decarbonization today for zero cost to the building owner.
Again, because we're deploying it financed through demand response revenues. We turn new things on or off in the winter and shift their load, and that generates enough revenue to pay for the full implementation of the system.
Gil: So you're able to do the demand response because of the sensors on, on the.
Cozy and the how does that work?
Marshall: Yeah. We, we already have full building diagnostics, right? The cozy is wirelessly connected to the cloud. We have data analytics teams. We know exactly when the building needs heat, when it doesn't, if it's gonna get windy, if it's gonna get snowy, right? We can take all this information and including in the summer, sign into the, the heat pumps to control the heat pumps based on what they actually need to do to maximize demand response revenues while maximizing comfort.
And, you know, on paper it works super well. We'll be deploying the first systems this year.
Gil: I, I wanna come back to the channel strategy. So tell us about the partners, right? It's, it's these, uh, HVAC contractors. It's the building owners as real estate agents, like break down the, the universe of, of partnerships that are gonna help you, um, educate the market.
Marshall: Yeah. So this year we, or 2024, we, um, about 50% of our sales were through sales partners and our installs are, you know, 90% through install partners.
And sometimes it's the same entity who are helping to sell and helping to install. But more often we'll be introduced to customers through companies that exist to help buildings figure out what to do. Right. So there's a number of businesses that evaluate buildings, tell them how much they're consuming, tell 'em where the opportunities are for efficiency.
And they often recommend us because we're a really good solution for them. But the universe of partners could be, you know, people who install plumbing. Contractors, air conditioning contractors. These are hot trades right now for sure. Absolutely. And you know, our system's a lot easier to install than a lot of the other ones, so you can do it faster.
The economics are really good, so they'll make a lot of money. And our job is to make all of our partners a lot of money, right? Like you wanna motivate everybody, the building owner, the resident, and the the installation partner to move as fast as possible and be excited about what's happening. So, yeah, I mean, like if you have expertise as a company in getting into people's homes and doing anything there, you're probably able to install a window heat pump, right?
Or put, uh, enclosure over a radiator. So the universe of potential partners is, is vast. And this is in contrast to full electrification, right? Like. A heat pump, a traditional heat pump requires an HVAC technician to install. And trust me, when I say I'm a huge fan of heat pumps, like I think they're amazing, but they're not for everywhere and not for everything.
But they're for most, they're not for everywhere. Everything. They work, you know, they're getting better and better and, but there's not enough trained HVAC technicians.
Gil: Yeah, I found that myself. You know, they're sort of skeptical when you ask them about it or they don't know, or they try to bring you back to the traditional, um.
Hvac.
Marshall: Yeah, a lot of, I mean like people just don't have trust yet, and that will change. And that's actually one of the reasons why we're doing happy electrification because it's a much harder conversation to say, Hey, let's just rip out your boiler and install this new system you've ever used before.
Whereas we are saying, Hey, we're gonna heat you most of the year with heat pumps, and then when your boiler does die, we're gonna know first because we're controlling the whole thing, we're gonna say, Hey, your bull just died. It might be February, like, whereas it would've been an utter emergency before and you just get a new boiler, now you have time because our hybrid electrification system can heat you in the coldest weather of the year.
And this is the full electrification solution we've done for, for your building. We've already talked to you about it. Press this button and we'll do it. And we've optimized that solution so much for you that it costs less than your boiler replacement. Our goal is, is not only to do majority electrification today, but set up the building for full electrification when the boiler does die.
Gil: Yeah, makes complete sense. How have you thought about this solution in the, maybe it's not the best analog, but um, you know, I always think of nest when they took off and what that meant for energy efficiency in dr. Observing that or what have you learned from that?
I mean is is there still like a, do customers want the gamification element? Like do you have a cool app or is there We do, or is that We do, we're sort of beyond that in some ways is you just want it to work and save you money.
Marshall: People just want it to
work and they want. To be comfortable. So we have an app, we have all, you know, the the gizmos and we're always making it better.
And everybody opens the app and they often open it once. That's right. And then they set their temperature and they never look at it again. And that's great. It's what you'd expect, right? Like by and large, most people don't care about the radiators. It's there. It provides heat. They only care about it when it gets super hot or super cold.
And so if they can set a temperature and never think about it again,
Gil: or they're
fighting with their partner
about that.
Marshall: Sure. Exactly. The people who do care. Is the building owner, the person who pays for fuel,
Gil: you're darn right.
Marshall: So we have this whole dashboard for, you know, those teams that gives insights and alerts.
You know, we can tell you like, Hey, apartment one C, the radiator just got cold and it's not heating up again. It's probably a busted steam trap or air vent or whatever it is. You should send a team to fix it, and that's before the resident gets cold. So there's a whole level of analytics that, yeah,
the supers love you guys, right?
Yes. There's
less,
um,
that's right of complaints. There's enormously fewer complaints and that that is one of the primary value props.
Gil: What are the common misconceptions still today, and how are you overcoming those amongst perhaps building owners?
Marshall: The main one that we've overcome is trust. So as you can imagine, if you own a building, you are bombarded with sales.
You know, people saying, I can do this, I can do that all day, every day. And you know, we are another one of those voices and you know, why is the building gonna trust that we can save 30% when they got 30 emails the day before about another company that can save 30%? And the way we overcame that. Is by primarily getting that a hundred million dollars debt facility with clear Gen and Blackstone, right?
Like they went through, we went through an enormous amount of diligence with them, and now that we can go to a building and say, Hey, you know, ultimately Clear Gen and Blackstone, who you are very familiar with, will pay a lot of money to install this. Not only does that bias trust for the customers who would purchase through a subscription, but it buys us trust through people who won't.
Purchase through a subscription. So it's increased sales across the board as a result. So that's, you know, you gotta put your money where your mouth is and when someone else is willing to do that, that's a pretty good indication that it's a real thing.
Gil: Fantastic. We've been talking a lot about New York where you all are based and where there's tremendous market opportunity, but.
As you've grown, I mean, you're looking at other markets, right? Tell me about where you're going.
Marshall: So we're deployed mostly in New York City right now. There's a pretty significant expansion push this year, but we already have units in Boston, Providence, dc We are now expanding to Chicago.
So our goal is to have about 10% of our sales in in other markets. This year. And then we raised a series A in 2023 with a great firm called 2150, and they're a European focused climate vc. And that's because Europe is our next expansion market. You know, any building that had significant growth before 1960 and certainly before World War II has a ton of radio heated buildings.
And all of these buildings where there's steam or hot water have this significant barrier to electrification that that hyper electrification can overcome.
Gil: Uh, fantastic.
We ask all our guests sort of a series of rapid fire. Questions.
So most of these are fill in the blank. First question. The word or phrase I most overuse is
Marshall: resource efficient decarbonization. Alright, that's good. That's a good acronym though.
Gil: Uh, the key ingredient to my productivity is,
Marshall: um, existential dread. That tends to be a motivator. Yeah.
Gil: Your favorite sustainability buzzword and your least
favorite.
Marshall: Yeah. So let's start with my least favorite, least favorite is, um. What's it called? Mega therms.
Oh.
Why is that your least favorite? Just connotes some monster or, it's just annoying. It's annoying phrase.
Mega therms. Yeah.
Most favorite. If it's not resource efficient decarbonization is decarb
de No, that's a tough one.
But we're all using it, right? I, I mean, I say hybrid electrification a lot too. Okay. These days I'll let you, I'll let that pass.
Gil: The most challenging part of my job is,
Marshall: I think it
has to be just staying, staying on mission. It's been a long road. We've been in this for a long time, right? There's a huge number of barriers and then you get, you know, policy changes that you have to adapt to.
A mentor
Gil: that inspired me,
Marshall: professor esis, my PhD advisor. I had a job before, before getting my PhD in Boston at a, at a, you ever heard of Q LED TVs?
The Samsung Q led?
Gil: Yeah. I have a, I have a quick follow up on that, but go ahead.
Marshall: So I, I was at the company that invented that and got acquired by, by Samsung and he was one of the, he was almost a founder, but he knew he was gonna be a professor. And when he left, I followed him because he was so great. I was like, Hey, can I join your group?
And he's extraordinarily entrepreneurial. He's. Extraordinarily smart and definitely an enormous source of of support and ingenuity for me. What was the name of the lab clue? Columbia Laboratory for Unconventional Electronics.
Gil: Oh, that's such a great acronym and a name. Yeah. You had fun in there. I bet.
Marshall: We
had a lot of fun.
So you have patents for these Q led technologies that we see in our TVs. My question is, does this make you like an uncompromising, um, person when you're at Best Buy? Deciding which TV to buy for the Super Bowl?
For sure. Although I, I'll say like, we don't really watch TV in my house. Ah, I have a tv. It's super old.
But if I, if I were to buy a tv, I'd be like, I know exactly what we're buying. Yeah, for sure. I mean, I can bore anybody, like beyond the realm of possibility. So
Gil: don't go to Best Buy
Marshall: with you because you know. Yeah, exactly. I can be like, this is why this TV is great, and I'll explain to you exactly why the color gamut is fantastic.
Yeah.
Gil: Now I'm having a little insecurity about the TV that, that I just bought mindlessly.
Marshall: We shouldn't, shouldn't go there.
Gil: TVs. All TVs are great. Yes. Well, putting TV aside, the book that has influenced me the most is,
Marshall: oh my gosh.
I dunno. I really like Enders game when I was little. Oh yeah. It's like the only book that I, I made my wife read that she also loved. So like I, it has like a universal appeal. I think about that book a lot. Have you read it to your kids? No, they're Wait. No. Too young. Yeah, too young. I'm waiting.
Waiting with bated breath for Harry Potter, but I haven't even read Harry Potter. I'm excited to read it with them.

things themselves. Yeah. How to fix stuff. How to build stuff.
