IFS completed a $4.9 million HVAC renovation for the Hannibal School District to improve comfort for Hannibal High School’s more than 1,000 students. Under the direction of prime energy services contractor, Performance Services, Inc. (PSI), IFS designed and installed a completely new HVAC and controls system. Since the high school did not previously have air conditioning in most of the building, the school closed an average of eight days each year due to high temperatures. IFS also installed HVAC equipment and controls to serve portions of the Hannibal Career and Technical Center (HCTC).
Despite the large scope of the project and a condensed schedule, IFS successfully installed 52 heat pumps, 10 rooftop units (RTUs), two chillers, one fluid cooler, seven boilers, 27 fan terminal units, 30 dual duct boxes, and all pumps, peripherals and controls in less than 12 weeks. IFS was able to complete their scope within schedule through diligent project management and constant communication between trades.
One of the primary project challenges was installing extensive ductwork and equipment within the 90-year-old high school building without changes in structural work. Under the direction of PSI, IFS was able to establish duct paths from each HVAC unit to provide fresh air for 43 classrooms while minimizing the number of chase walls that were required to conceal the ductwork.
In addition, IFS reduced the install time of the piping fittings that serve all 52 water-source heat pumps by using Victaulic and ProPress fittings. Victaulic’s virtual design team created a 3D scan of the boiler room and provided cut sheets for more than 150 custom fittings.
As part of PSI’s energy savings contract, IFS selected equipment with integrated BACnet interfaces so that PSI and IFS controls engineers can monitor and control equipment remotely and effectively without the added cost of additional controls. PSI and IFS’ standard control sequences include energy-saving measures such as optimum start and stop, demand limits and resets, as well as night setup and setback.
