A plant built in the 1960s recently shifted its manufacturing operations to a different location leaving this plant to serve as a warehousing, packaging, and shipping facility. The plant had installed three chillers with a constant speed pumping system to serve its cooling needs. Some sections of the plant were expanded in the 1980s and rooftop units were added to better deal with the increase in cooling demand. Since then the plant has operated without any significant upgrades to its HVAC system. Mechanical equipment has gotten more energy efficient over the years. This thesis looks to improve the current pumping and air distribution system. However, there was a lack of information on the kind of air distribution system the plant uses. To deduce this, an energy model was created in Carrier HAP using the utility bills obtained from the facility. It pointed to the plant using a Constant Air Volume system with electric reheat in some zones. An additional benefit of the energy model is that it helps to examine the effects of recommendations on the current chiller system and better understand the costs of operation. Four different recommendations were made which consider various water-side and air-side HVAC arrangements to find the most energy efficient option. Implementation costs were looked at along with simple payback periods to determine the most practical solution for the plant. A primary secondary loop along with VFDs on the cooling tower loop proves to be an optimal strategy for the plant to adopt. Changing the air side system will reduce the energy bills by a huge margin but would prove to be extremely uneconomical to implement.
