• BR+A developed two equipment options to deliver environmental requirements <br />(temperature & ventilation) with both options including new digital controls. <br />• Option 1): Reuse boiler & chiller, add energy recovery ventilation (ERV) and <br />variable refrigerant flow units for additional cooling capacity requirements <br />• Option 2): Replace boiler and chiller with newer, higher efficiency units, new <br />fan coils (ECM), and energy recovery ventilation (ERV) <br />• SBA contracted Shawmut Construction to perform constructability analysis of <br />1/24/14 DD plans, as approved by AhCCAC, and add both equipment options 1 & <br />2. This includes construction estimate, schedule, and value engineering <br />suggestions. <br />• SBA contracted BR+A to <br />perform a building energy model and <br />Life cycle <br />costing <br />analysis for implementing <br />option 2 and to add higher insulation <br />values in <br />the walls <br />and ceiling. <br />• SBA, BR+A, Shawmut and Town of Lexington met.January 29, 30, February 5, 7, <br />12 (with Energy and Sustainability Committee members), 13, 26, and March 3 to <br />discuss the options, costs, and schedule impacts of the various scenarios. <br />
