Subject: Make Way for Trenches! A College Plans to Scrap Its Entire Heating System
Welcome to the May 2019 edition of our newsletter about buildings, grounds, and more. Go big or go home, a friend of mine likes to say, and it sure seems Dartmouth College has decided to go big: The college is planning to replace not just its central steam plant but its entire campuswide heating network. The project, which is just getting started, is an undertaking that I’m sure many other institutions will want to watch.

Make No Little Plans: Dartmouth Envisions an All-New Heating Network — for 119 Buildings
In 1898, when Dartmouth College opened its current steam plant, heating more than a dozen campus structures with high-pressure steam from central boilers was innovative. Over the decades, the plant has been expanded — it now serves 119 buildings — and upgraded so that it also generates electricity, and its fuel was switched from coal to oil. Even so, says Joshua Keniston, the college’s vice president for institutional projects, the whole system is “really quite dated.”
“We’re feeling like, How do we become innovative again?” he says. The answer sounds audacious: Start from scratch. And not just with a new system, but also with a new business model for it.
So the college is seeking a business partner — one with ideas, expertise, and capital — with which to build a new central plant fueled largely by wood chips from local timber operations. The plant would produce hot water, not steam, and a new network of pipes would deliver that hot water around the campus. In some buildings, connecting the hot-water lines to the current heat-exchanger system will be fairly easy, but in a number of older buildings, “it could mean going in and opening up walls,” says Keniston.
Much of the motivation for the project, which Dartmouth says could cost $200 million, comes from the college’s quest for environmental sustainability. Two years ago, President Philip J. Hanlon set a 2025 deadline for cutting greenhouse-gas emissions in half, and also for replacing No. 6 fuel oil — the steam plant burns some 3.5 million gallons a year — with renewable fuels.
But the college is also eager to get out of the business of running its own energy company and concentrate instead on its academic mission. After studying other institutions that have created similar types of partnerships — including Ohio State University, which contracted out its parking operations and then its energy infrastructure — Dartmouth is estimating that an experienced private partner could get it 10- to 20-percent greater efficiency, Keniston says. “We see a lot of value in having a firm that runs six or 14 or 100 other plants and can bring that knowledge of day-to-day operations.”
The other big savings — “the headline,” Keniston calls it — comes from replacing the steam system with a hot-water network, which is expected to be 20-percent more efficient. “Because steam is so hot compared with the temperatures around it, there’s a lot of heat loss as you transmit it to the buildings,” he says. “There are some uses where you need the energy that’s contained in the steam. Having nice even heat in all your buildings is not one of those uses.”
In the existing system, he says, steam goes on in a building once an hour to warm it up. Then the steam cools and pipes carry the condensate back to the plant. “With hot water, if we keep it consistent, we don’t have those dips. It becomes more comfortable for building occupants.” A hot-water system can also be set up so that it’s easier to control locally. A drawback, he says, is that a hot-water system relies on pumps, so “as we think about our resiliency and redundancy, we have to make sure we have electricity to run those pumps.”
Another challenge will be locating the new plant. The current facility is hemmed in by the Hood Museum of Art, a visual-arts building, two residence halls, and an athletics complex. There’s no room to expand and add storage for wood chips. Next week the college will identify several potential sites for a new plant within a two-mile radius — farther than that, and the system would become less efficient.
But the plant isn’t expected to be the big challenge. Keniston says Dartmouth has 26,000 feet of steam pipes, most of which will need to be replaced. “That means we have to dig up all of these trenches around campus. We have to go into 119 buildings and transition them over.”
Once it’s in place, a hot-water system will offer the college more options. A dozen or so Dartmouth buildings have solar panels, but they can’t be tied into the existing steam system because it’s pressurized. Hot water isn’t. “So if we wanted to put in thermal solar, or heat pumps, or geothermal, over time we can supplement that on a building or subdistrict level,” says Keniston. “We see the conversion to hot water as something that serves us for 100 years.”
Like Middlebury’s biomass-gasification plant, the new Dartmouth biomass facility would be supplemented by equipment for burning a liquid biofuel to meet peak winter demand or serve as backup while maintenance work is done on the biomass side. “The energy market is shifting pretty quickly,” says Keniston, “and having both gives us some flexibility in selecting the most sustainable and renewable fuel sources that we can.”
Working with private companies is hardly new in higher education, even for energy-related projects, and it’s becoming increasingly common. Ohio State’s may be the best known deal, but the University of Maryland had an earlier partnership with Ohio State’s partner Engie; the University of Oklahoma has a partnership with Corix; and just recently, the University of North Alabama signed on with Schneider Electric to modernize some 70 buildings and reduce campus energy use by a fifth. But Keniston says Dartmouth’s project is “probably among the first that has all of the components in this particular arrangement.”
The college has set up a two-stage process for choosing a partner. In the first stage, Dartmouth asked interested companies to describe their qualifications and high-level ideas, which the college is now assessing. In the second phase, which Keniston expects will begin this fall, between two and four shortlisted contenders will be more closely evaluated. Clearly, there’s interest: About 150 people people attended an industry open house in March to see the college’s existing facilities and hear more about what it wants.
A top priority will be finding a partner that can provide 24/7/365 reliability. “As we look at the qualifications for partners, we will be looking for teams that maybe have worked on military bases that have really intense reliability requirements,” says Keniston. Also, Dartmouth wants to be sure it finds a partner it can work with for at least the next three decades.
Dartmouth’s other big concern has been the deal itself, he says, and the college has spent months thinking it through with members of its facilities, finance, legal, and risk teams. “As we transition away from being the owner-operator, we have to think about how we structure this in such a way that we’re going to get what we need, and we’ll be paying a fair price for it” for 30 to 35 years. For Dartmouth, he says, “it’s a really different way to operate.”

A Reader Recalls the Mattin Center — Mice, Roaches, and All
Our recent Campus Spaces special section mentioned the Johns Hopkins University plan to locate a new student center on the site occupied by an 18-year-old arts complex, the Mattin Center. It was designed by a prominent firm, Tod Williams Billie Tsien Architects, and many architecture fans love it.
Hopkins didn’t reply when we asked to talk to someone about the building, but last week a former employee who worked in the complex wrote with his recollections. Because he’s still employed in higher education, he asked not to be identified. Here’s some of what he had to say:
I understand that from the outside and upper floors of the building, it is unique and interesting. The few rooms that are above grade are all windows and are beautifully lit as a result. Unfortunately, this is maybe a third of the space in the building. The rest of the rooms are at or below ground level. They are often dark and damp. We saw mice and cockroaches on a weekly basis.
The entire building is poorly constructed. For years, architecture firms would tour the building as an example of what to not allow contractors to do in construction. It was poorly ventilated — freezing in the winter, incredibly hot in the summer. Those upstairs rooms that were so nice in the spring and fall swung wildly in temperature in the cold winter and hot summer. Cracks in the foundation, outside staircases, and floors were so commonplace that large areas of the building were often cordoned off.
When the university found the need for offices and student meeting space to outweigh the need for darkrooms, it found renovating the building was impossible. The inner walls were made of concrete, making it impossibly expensive to move rooms or install new doors. Much of the limited interior is taken up by large foyers that are dead space. To make do, students would often practice debate and rehearse performances on staircases.
Additionally, the building is incredibly confusing to navigate. There are at least 10 exterior doors. Many of the doors chosen by the architect are also so heavy that they could not be motorized to be ADA-compliant. To this day, I do not think that someone in a wheelchair could easily go to the bathroom in this building.
So over all, I and most people who were subjected to working in the Mattin Center considered it an abysmal failure and an example of architects placing form over function. There may have been a brief time that the building met the needs of its inhabitants, but due to its inflexibility and poor design, we quickly outgrew it.
