The HVAC systems in all buildings have been reviewed. In addition to increasing the levels of filtration via the installation of MERV 13 filters, which remove about 90 percent of all particles in the air including viruses such as COVID-19, our air-handling units have been programmed to allow the mixing of more outside air to help refresh the air inside buildings. Opening windows and doors for cross-ventilation is recommended whenever possible.

Academic Buildings HVAC Summary

Buildings have been fitted with MERV 13 filters (all units provide outside air):

• Doubleday
• Kenyon Hall
• Ingram Library
• Thompson Library
• New England
• Powerhouse Theater
• Sanders Physics
• Sanders Classroom
• Swift Hall
• Vogelstein Center for Drama and Film
• Weinberg Field House

Summary of the air handling systems in other classroom buildings:

Rockefeller Hall: The majority of the building is heated with steam radiators, so there is no air circulation. MERV13 filters have been installed for the 200 and 300 classrooms as well as the 4^th floor where there are air handlers.

Skinner Hall: The Recital Hall and the Listening Room units have been fitted with MERV 13 filters, both units provide outside air. The rest of the building is heated with steam radiators, so there is no air circulation.

Blodgett Hall: The auditorium, lower level and second floor Labs 23A through 35, Animal Quarters, Room 106, Rooms 209 through 215 have all been fitted with MERV 13 filters. Additionally, they all bring in outside air. The rest of the building is heated with steam radiators so there is no air circulation.

Taylor Hall: The units that heat Auditorium T102, Lecture Hall T203, and second floor classrooms, T205, T206, offices T214, 215 & 216 have been fitted with MERV 13 filters. Additionally, all units provide outside air.

Ely Hall: Second-floor classrooms 200 through 204 have been fitted with MERV 13 filters and all units provide outside air.

Chicago Hall: The new laboratory has been fitted with MERV 13 filters and the units provide outside air. The rest of building is heated with hydronic system so there is no air circulation.

The Bridge for Laboratory Sciences and Olmsted Hall: Both buildings are fitted with filtration systems equivalent to MERV13 and supply air entirely from outside (no recirculation of interior air).

Barn: MERV 13 filters are in the space serviced by the air handlers.

Old Laundry Building: The second-floor spaces have been fitted with MERV13 filters. In the rest of the building, the systems cannot support the enhanced filters.

Administrative Buildings HVAC Summary

Buildings have been fitted with MERV 13 filters (all units provide outside air):

• Computer Center
• Facilities Operations
• Gordon Commons
• Kautz House
• Receiving
• College Store at the Juliet Building

Summary of the air handling systems in other administrative buildings:

Baldwin: The entire building is heated with steam radiators, so there is no air circulation.

College Center: The HVAC systems that cover the first and second floor of the north side of College Center, the second floor on the south side of College Center, the MPR, and the Villard room all have MERV 13 filtration installed. Also, all these units bring in outside air.

Alumnae House: The HVAC systems in the basement, first floor, and the third floor have all been fitted with MERV 13 filters and the systems provide outside air in those spaces. The rooms on the second floor have their own systems which do not share air with other spaces but also can’t accommodate MERV 13 filters and don’t bring in outside air.

Main Building: The offices for Residential Life, Campus Activities, Campus Response, and the offices on the south end of the second floor have air handling units which have been fitted with MERV 13 filters. They also bring in outside air. The remainder of the building is heated with steam radiators so there is no air circulation.

New Hackensack: Does not have the ability to be fitted with MERV 13 filters. The whole building is heated with baseboard heat which does not have air circulation. Additionally, the art department spaces, have air handling units which provide outside air to those spaces but cannot be fit with MERV 13 filters.
