Lexington Children's Place— Donna DiNisco, (DiNisco Designs), Vivian Low(DiNisco Designs) Donna updated the committee the late start for demolition was due to National Grid's delay on getting the natural gas on site capped. Demolition is now underway; however, S&R is slightly behind schedule with an original date of completion by Sept. 1St. S&R is working hard to wrap up demolition before Sept. 11 to • Filed sub bids have been received and need to be awarded by Sept. 10th. The GC bid date has been extended. • A review of the August 1St, 2018 Green Engineering Report stated: "Figure 1 below presents the energy use index (EUI)of the Code Baseline and the Proposed Design. In summary the design exceeds ASHRAE 90.1 2013 requirements with 50% site energysavings. This translates to a LEEDv4 energy cost savings of 20.6%. It is important to note the distinction that Code references energy use performance while LEED references energy cost performance. The Green House Gas(GHG) emissions for the proposed design are estimated at 34.5 MTCO2e, an approximately 40.2% reduction from the Code Baseline." • PBC discussed the topic of gas onsite brought up at the Aug. 28th BOS, SC and PBC meeting. There is apparently a big misconception in town about the intent of this emergency gas fire element and the presents of gas on the site. The existing building had gas service. The gas fired element being proposed is strictly for emergency use during the coldest months of the year should there be a utility company power outage. The proposed emergency generator is being sized to provide power to run the life safety requirements of the building, primary functions related to the buildings required `resilience' rating, and the two VRFs service the classroom wings. The option is to upsize the generator and burn more fuel generator electric or supply an inexpensive gas fired element to heat the administrative wing. Further discussion is needed regarding using gas for backup use only. 5. School Master Plan Discussion— Kate Colburn (School Committee) Kate addressed that the last School Master Plan was in 2014, with projects being completed and new ones beginning. Enrollments continue to rise, and the SC suggests taking a new look at the current Master Plan. Kate would like to form a group of 15 people from various committees, and is looking to start efforts in Sept. and complete the review by the end of the school year. Mike Cronin suggested that PBC members interested in participating on the School Master Plan should email him. PBC Meeting 08.16.18 4
