AVON — Council heard a proposal to fix the police station’s roofing woes as it looks to mitigate problems with the building envelope and HVAC system.

The roughly 10-year-old building has a problem with ice damming and moisture buildup, due to how the second floor space was constructed. Right now, the building’s attic space — where the department’s workout area and storage are — has vents to the outside, but its HVAC is not tied into the lower level. This allows cold air into the attic, which builds up condensation and allows ice to form in the winter or drive cooling costs up in the summer.

What presenters Ben DiMarco, owner of DiMarco and Associates, and Mark Cannella, owner of Pro Energy Consultants, proposed is to seal off the vents in the attic, and tie in the HVAC to the first floor, making the upstairs a fully conditioned space. Both companies have looked at the building’s problems in the past.

“The police department (problem), although pretty significant, is pretty common to what we see,” Cannella said. “From our diagnostics what we found was a lot of cold infiltration, air coming in, based on the design of the attic area (or) the second floor.”

When the station was built in 2008, it was built similar to a house, DiMarco said. The attic was made into the second floor but was not originally designed as such, causing the mix in whether or not it was meant to be a conditioned space.

“The HVAC systems do not have the cold air returns ducted down into the office spaces,” DiMarco said. “What we presented to the (Police) Chief was a way to seal off the building and insulate it, and get those HVAC systems tied together down to the lower level … what we’re looking at is a way to prevent further damage down the road (with) constant ice damming and water infiltration and all that.”

The proposed timeline, if approved by Council, would be to start in October and have the bulk of the work done in two to three months, Cannella said. The companies would look to be done by Jan. 1, and monitor with infra-red testing to make sure the problems have been remedied after that. Further checks could be done a couple of times a year after the first year, similar to how the companies have handled other projects in the area.

Mayor Bryan Jensen was concerned with what changes would do to the longevity of the station’s roof — especially how much it could heat up in the summer without airflow.

Cannella acknowledged the roof would heat up, but said it was OK.

“In a residential home we put insulation on an attic floor, so the attic gets extremely, extremely hot,” he said. “And that’s OK. And it gets extremely, extremely cold (too), but the reason that we put our thermal barrier in the attic floor is to stop it from getting into the first floor. So currently right now you have insulation on the roof deck, which is fine. But that ventilation should have been blocked off initially when they made it conditioned space. So it’s (the roof) going to get hot, the only way to stop it, frankly, is to block the sun.”

In terms of disruption to police work DiMarco said they had talked to Police Chief Richard Bosley and would minimize disruption via a coordinated work schedule. The work also would not touch the city jail or dispatch at all, Bosley said.

When voting, Council approved $300,000 toward fixing the building envelope, though Finance Director William Logan said DiMarco’s quote was for $278,000. The approved appropriation does not mean the city will move ahead with DiMarco and Cannella’s proposal.

Members also approved re-appropriations for pedestrian flashing crosswalk signs at Stoney Ridge Road and Harriman Trail, along with three other locations — for $60,000; and an increase in appropriations for the Aquatic Facility by $15,000 for 94 gallons of pool paint and other expenses. It unanimously approved several new positions throughout city government and compensation rates for them.
