Fire Station Exterior Design Review with HDC— Jeff McElravy& Matt Salad (Tecton Architects) John Wilson (Lexington Fire ChieQ Jeff's presentation showed a front schematic rendering of the proposed Fire HQ. Front, back and side elevation drawings were also presented. • The four bay doors will utilize a bi-fold door which opens to the side. The doors open quicker, are more reliable, and won't block ceiling lighting & sprinklers like an overhead opening door would. • Solar for hot water collector will be located on the back roof shielded from view by gables. The rest of the roof will be covered in solar [PV] panels. • Exterior material samples were reviewed by the HDC. HDC commented on the expanse of concrete in front of the apparatus bay doors and a desire to break up the mass visually. It was asked if something could be done to make it look more inviting; possibly stamping, adding a color or adding a stripe for each bay door. This will be further reviewed by the design team. • Truck washing will be done in the back of the building with special drainage for water disposal, and won't have an effect on the concrete area in front of the bay doors. HDC's portion of the Fire Station Review concluded at 7:351). Continued Fire Station Review with PBC Jeff discussed with the committee the use of a Gas Boiler System to serve the Radiant Floor. Radiant flooring would only be used in the apparatus bay area during the winter months. The gas boiler could also serve for emergency backup to help during power outages which would reduce the emergency generator size. • PBC asked about the size and footprint of the emergency generator and decibel difference as well as the day tank size and overall unit size. • DPF asked if the radiant floors are to be heated by gas; what the cost savings and operating costs would be. 201 BEDFORD STREET 9 LEXINGTON, MASSACHUSETTS 02420
