Joint Meeting: Selectmen and School Committee—August 28, 2018 Page 1 of 3 ,Joint Board of Selectmen and School Committee Meeting Tuesday, August 28, 2018 A3 ;Joint Meeting of the Board of Selectmen and School Committee was called to order at 6:00 p.m. on 'Tuesday, August 28, 2018 in Estabrook Hall of the Cary Memorial Building for the Purpose reviewing the proposed emergency heating/cooling systems for the new Lexington Children's Place (L CP). Present for the Selectmen (BC S) were Ms. Barry, Chair; Mr. Pato; Mr. Lucente; Ms. Hai; Ms. Axtell, AssistantTown Manager; and Ms. Siebert, Recording Secretary. Ms. Ciccolo was recused and not present. Present for the School Committee (SC) were Ms. Jay, Chair; Ms. Colburn; Mr. Alessandrini; Ms. Linehan; Ms. Sawhney; Dr. Hackett, Superintendent of Schools; Ms. Billings.-Fouhy, Lexington Children's Place Director. Also present: Mr. Cronin, Director of Facilities; Ms. DiNisco, DiNisco Design; Soon Oh, BAB International; Chris Schaffner, Green Engineer; Kevin Murphy, Thompson Engineering (late arrival). Mr. Cronin said that the pending question to be determined is what the emergency power system would be for the new 20,000 SF LLP building. An emergency generator is included in the building plan but because the heating system would consume much of the generator's output, a subsidiary power source is seen as necessary to extend the building's resiliency. Ms. DiNisco cited three main points for consideration: • What are LCP's program elements? • Based on the program elements, what are the project parameters? • What are the resiliency needs for the building? "oLarns elements: LLP is Lexington's year-round, State-mandated early intervention program for ages 2.9-5 years. Appropriate learning spaces, accessibility, and relevant services must be provided. A medical suite and administration offices are included in the design. The building is scheduled to be open by September 2019. 'The new LLP building is part of the larger elementary school plan which aims, in part, to alleviate crowding at the Harrington School. Expansion capabilities within the LLP building design allow for a higher population. Re,silienc �needs: The building is a hybrid of LEED design and Lexington's specific sustainable building requirements. It will have a resiliency level of 3 or 4, the lowest of the four categories, which is intended to preserve operations and protect the building asset. Normal operations will use electricity-only via VRF (Variable Refrigeration Flow) using ERU (energy recovery units). Electricity failure or VRF malfunction due to snow blockage, cold temperatures, or equipment breakage would leave the building without the ability to function.
