MECHANICAL SYSTEMS REVIEW - OFFICES/SENIOR CENTER <br />Furnace Room - Offices <br />The office space is served by three furnaces and <br />associated split system air conditioning units. <br />The units were installed in 2010 and are in good <br />condition. The ductwork connected to these <br />units would need to be replaced based upon the <br />condition of the current ductwork and the change <br />in zoning due to renovation schemes. In addition, <br />current requirements for ventilation air will require <br />an air-to-air energy recovery unit to temper the <br />outdoor air before it is introduced into the furnaces. <br />Furnace Room - Senior Center <br />The community space is also served by three <br />furnaces and associated split system air handlers. <br />They were installed in 2010 as well and are in good <br />condition. The comments for item 1 above applies <br />to these systems as well. <br />- One of the units has a capacity of 5 <br />tons. The Mn Energy Code requires a system of <br />this capacity to be equipped with an economizer. <br />The economizer introduces outdoor air into the <br />space when outdoor air temperatures are favorable <br />and cooling is required by utilizing outdoor air for <br />cooling as opposed to operating compressors. <br />CNH <br />ARCHITECTS 33 <br />
