You may hear some noise in parts of Darien Library, starting this Friday, Oct. 11 and continuing into December, and feel some cooler temperatures for a month, starting this Tuesday, Oct. 15 as work is done on the building’s HVAC system, the library just announced.
The project to improve the heating-ventilation-air conditioning system is meant to allow the library to stay a little warmer in the winter and cooler in the summer, according to the announcement.

“Due to the nature of the work, we anticipate that there will be less heat on the Second Level and Mezzanine between Oct. 15 and Nov. 15,” the announcement said.
“Please also expect the noise level to be higher than usual on the Second Level and Mezzanine.”
The library has a geothermal heating and cooling system that circulates water between the building and the ground under the parking lot (underground is cooler than normal summer temperatures and warmer than normal winter temperatures). This can save money and be better for the environment by allowing the library to use usee less fuel.

The latest project, meant to upgrade that system, “will replace many of the units in our HVAC system, adding air capacity.”
Last winter, new wells for the geothermal system were drilled under the heavily used parking lot, temporarily restricting space for parking. That project replaced a water-circulation system that wasn’t completely enclosed in pipes with one that is.
The library is also working on increasing parking available to patrons through an agreement to use some of the lots at the Thorndal Circle office park.

Announcing Library HVAC Work
Project begins Friday, October 11th
We are pleased to announce a project that will replace many of the units in our HVAC system, adding air capacity and making the library building more comfortable year-round. The project will begin this week and finish by the end of December. We will provide regular updates on the project.
What does it mean for me?
For visitors of the Library, it will mean an even more inviting environment in which to spend those hot summer days and cold winter nights. Due to the nature of the work, we anticipate that there will be less heat on the Second Level and Mezzanine between October 15th and November 15th.
Please also expect the noise level to be higher than usual on the Second Level and Mezzanine.
