Memorandum
Staff recommends your approval of the attached resolution authorizing a construction contract in the amount of $349,000.00 with Miller-Boldt Inc., for the replacement of the primary chiller unit at Guy C. Larcom City Hall.

The chiller is part of the building's HVAC system and the primary component needed to provide air conditioning. The existing 110 ton unit is nearly 30 years old. It is unreliable and obtaining repair parts for it is difficult. In 2014, the City installed a smaller 70 ton chiller which handles cooling during the spring and fall to help minimize operation of the primary chiller and to provide some cooling redundancy in the building when the primary chiller fails.

This project involves removing the 110 ton chiller and cooling tower, minor structural steel work, supply and installation of a new 70 ton air cooled chiller, new electrical supply, and all necessary connections and controls to operate the chiller. When completed, City Hall will have two 70 ton chillers that will normally rotate operations and work collectively when the cooling demand is higher than just one unit can handle.

Consistent with City Council Resolution # R-17-145, the City retained an engineering firm to review and evaluate different chiller technologies for energy efficiency standards. The study evaluated a number of different technologies that would work in City Hall and compared them for energy consumption, life cycle costs, resource usage, installation costs and the ability to be powered by renewable energy generation. The results of this technology study were evaluated by Facilities staff and the Manager of the Office of Sustainability and Innovations ...
