Energy Efficiency is a Heating, Ventilation, and Air Conditioning (HVAC) project proposed by Mitsubishi Electric. They created this project in order to replace the current HVAC system of Pontotoc Hall at East Central University in Ada, Oklahoma. The main objective of the project is to create a more efficient and economically viable HVAC system for ECU using the R2 and Y series HVAC components from Mitsubishi. The project must be supported with extensive data analytics of the original system along with the proposed system. Final construction documents must be presented to the client upon completion of the redesign.
