GREENWICH — Hamilton Avenue School is set to get a new geothermal HVAC system next September, after more than two years of political infighting over the project.
That’s thanks in part to the Representative Town Meeting, which overwhelmingly approved a $5.3 million bond to fund the replacement system at its meeting last week at Central Middle School.
The 142-18 vote to approve the project (and subsequent 149-2 vote to issue a bond to fund it) was achieved with very little dissent among the body, belying the months of partisan conflict in the town surrounding the project.
“Those voting yes felt it was time, after two years of discussion on this topic, to put this issue behind us,” said James Waters, the chairman of the RTM’s Budget Oversight Committee. “They felt it would be even more costly not to approve, in the interim, due to the ongoing monthly cost for the chillers.”
The school’s heating and cooling system failed in the summer of 2023, with Greenwich Public Schools facilities director Dan Watson saying at the time that it had been plagued by issues since at least 2009, and that it “wasn’t installed right, it wasn’t operated right, it wasn’t probably designed right.”
Initially, school district officials requested $3.2 million to replace the broken climate control system with a conventional, gas-burning replacement, but that was blocked by the RTM in December 2023. In the interim, the building has been renting cooling units and using its built-in boiler for heat.
In February of this year, the Board of Education reversed course, approving a $5.25 million geothermal system. But that funding did not make it into the town’s capital budget, after a portion was cut by Republicans on the Board of Estimation and Taxation in April in favor of a gas-burning system, over the vociferous objections of the board’s Democrats.
But the RTM cut the remaining funding for the system in May, on the grounds that it wanted to follow the BOE’s recommendation for a geothermal system.
Now, they have their wish.
At last week’s meeting, the vast majority of RTM members backed the new solution for the school, which was recommended out of several of the body’s committees with virtually no dissent.
“The vote for (the RTM) Public Works (Committee) was 9-0-0, by unanimous consent, and comments were 'about time, let’s get it done,'” Chairman Cheryl Moss said.
The plans for the new geothermal system, as well as its cost estimates, were drawn up by consulting firm AECOM.
(Only) one voice in the wilderness
One RTM member, Mark Fichtel, District 4, did speak up about the concerns of those opposed to the project, including that there was not a sufficient explanation for the failure of the current geothermal system and that he thought the difference in savings — estimated to be approximately $158,000 over 25 years for geothermal over conventional — were not large enough to justify the risks of a new geothermal system breaking.
“I feel a little bit like Cassandra, who begged the Trojans not to bring the wooden horse into the walls,” Fichtel said. “We’re facing a situation where we’re subject to the sunk cost fallacy, which says that because we’ve invested so much time (in a geothermal system), we have to go forward, regardless of any risks.”
According to the timeline approved by the RTM, the school district will attempt to fill a bid for the contract by February, have work start in April and install the new system by the next school year in September 2026.
From Greenwich Time November 19, 2023:
This geothermal HVAC system is the only one of its kind among all the Greenwich Public School buildings. It was installed during a major renovation of the school following the discovery of mold in the early 2000s. Hamilton Avenue reopened in 2009 after years of repair work.
Geothermal systems move heat from one place to another using electricity, according to the Department of Energy. These systems are more energy efficient than traditional HVAC systems because they move existing heat around as opposed to burning fuel to create it. As a result, these systems are cheaper to operate and they produce fewer carbon emissions.
Watson said he is not opposed to geothermal technology in general during the BET meeting on Nov. 14, but that he is “dead set” against using it at Hamilton Avenue, because the district is not equipped to handle the system.
“Geothermal systems are not easy to properly maintain and operate. In our current staffing configuration and model, we do not have the capacity to provide the oversight and the hands-on needs for a system of this complexity,” Watson wrote in a memo to the BET.
The BET approved the BOE’s $3.2 million request on Monday, and it now heads to the Representative Town Meeting for approval at its Dec. 11 meeting. If approved, GPS would be on schedule to replace the Hamilton Avenue system in summer 2024.
Original estimate was $2.5 million, $3.2 by 2023, and, as of today, $5.25; I detect a trend.

While searching for information on the history of the decision to use a geothermal HVAC system in Hamilton Avenue back in 2004 — I couldn’t find anything — I ran across this fun synopses of the Schools rebuilding odyssey, from the 2003 decision to fund it, to the start of construction, with an expected completion date the beginning of the 2007 school year, to the actual reopening date of February 18, 2009. Spoiler alert: things didn’t go as planned.
