The initial approach adopted at the biomedical factory was to upgrade the CHP on site. Two options were assessed, LPHW and ABO. The decision was made to install the ABO option as it has a payback period half that of the other option. Management then recognised that to make further inroads in energy savings, investment was needed and this included cooling tower, motor, air compressor and heat pump upgrades.
Lighting upgrades from halogen to LED were implemented in some of the factory zones. For a heat pump upgrade, a capex of 2.4 million euro had a payback period of 2.64 years making it a very effective upgrade. Air handling units also underwent belt upgrades to maximise their efficiency. The ducts on site also required sealing and this project had a payback period of 2.3 years. For the site to make even more savings and create a green image a solar array was suggested to be installed.
