Installation of a test well to determine existing geothermal groundwater conditions for the Beverly Library’s new Geothermal HVAC system. The City of Beverly has launched a project to decarbonize Beverly’s main library and improve building performance, air quality, and service to community members as a cooling center in the summer. After 30 years, the current HVAC equipment has reached the end of its useful life and is in need of replacement. The condensing unit serving one of the Roof-Top Units (RTUs) providing ~40% of the cooling for the library has already failed. In mid March this one test well was drilled to confirm the existing geothermal groundwater conditions. The project is expected to be completed in Summer 2024. Using a phased construction approach, the library expects to remain operational during construction. In 2021, the City ran a study to understand and compare HVAC replacement options. The City evaluated the cost and performance of replacing the existing system with similar equipment, as well as alternative options such as air-source heat pumps and ground-source heat pumps. The City found that a ground-source heat pump system, or a geothermal system, was the best option to reduce the most energy use and eliminate on-site fossil fuel use by removing gas-fired equipment. Geothermal technology makes it possible to heat and cool the library using the Earth’s naturally stable below-ground temperature–a renewable energy source. In Resilient Together, the City’s climate action plan, the City committed to leading by example through adoption of smart, clean, net zero technology in existing and new municipal buildings. Buildings are the largest source of greenhouse gas emissions, and this project is expected to remove gas entirely (21,000 therms to zero) and reduce HVAC electricity usage. This helps the City meet its goal of reducing its carbon footprint by 50% by 2030.

Installation of a test well to determine existing geothermal groundwater conditions for the Beverly Library’s new Geothermal HVAC system. The City of Beverly has launched a project to decarbonize Beverly’s main library and improve building performance, air quality, and service to community members as a cooling center in the summer. After 30 years, the current HVAC equipment has reached the end of its useful life and is in need of replacement. The condensing unit serving one of the Roof-Top Units (RTUs) providing ~40% of the cooling for the library has already failed. In mid March this one test well was drilled to confirm the existing geothermal groundwater conditions. The project is expected to be completed in Summer 2024. Using a phased construction approach, the library expects to remain operational during construction. In 2021, the City ran a study to understand and compare HVAC replacement options. The City evaluated the cost and performance of replacing the existing system with similar equipment, as well as alternative options such as air-source heat pumps and ground-source heat pumps. The City found that a ground-source heat pump system, or a geothermal system, was the best option to reduce the most energy use and eliminate on-site fossil fuel use by removing gas-fired equipment. Geothermal technology makes it possible to heat and cool the library using the Earth’s naturally stable below-ground temperature–a renewable energy source. In Resilient Together, the City’s climate action plan, the City committed to leading by example through adoption of smart, clean, net zero technology in existing and new municipal buildings. Buildings are the largest source of greenhouse gas emissions, and this project is expected to remove gas entirely (21,000 therms to zero) and reduce HVAC electricity usage. This helps the City meet its goal of reducing its carbon footprint by 50% by 2030.

The City found that a ground-source heat pump system, or a geothermal system, was the best option to reduce the most energy use and eliminate on-site fossil fuel use by removing gas-fired equipment. Geothermal technology makes it possible to heat and cool the library using the Earth’s naturally stable below-ground temperature–a renewable energy source. In Resilient Together, the City’s climate action plan, the City committed to leading by example through adoption of smart, clean, net zero technology in existing and new municipal buildings. Buildings are the largest source of greenhouse gas emissions, and this project is expected to remove gas entirely (21,000 therms to zero) and reduce HVAC electricity usage. This helps the City meet its goal of reducing its carbon footprint by 50% by 2030.

Installation of a test well to determine existing geothermal groundwater conditions for the Beverly Library’s new Geothermal HVAC system. The City of Beverly has launched a project to decarbonize Beverly’s main library and improve building performance, air quality, and service to community members as a cooling center in the summer. After 30 years, the current HVAC equipment has reached the end of its useful life and is in need of replacement. The condensing unit serving one of the Roof-Top Units (RTUs) providing ~40% of the cooling for the library has already failed. In mid March this one test well was drilled to confirm the existing geothermal groundwater conditions. The project is expected to be completed in Summer 2024. Using a phased construction approach, the library expects to remain operational during construction. In 2021, the City ran a study to understand and compare HVAC replacement options. The City evaluated the cost and performance of replacing the existing system with similar equipment, as well as alternative options such as air-source heat pumps and ground-source heat pumps.
