. This report presents results of assessment of medium and large AC technologies used in commercial and public buildings in the Pacific countries. The air-conditioning technologies assessed are: Variable Refrigerant Volume/Variable Refrigerant Flow (VRV/VRF) systems, Reciprocating Chillers, Screw Chillers, Scroll Chillers and Heating Ventilation and Air-conditioning (HVAC) units with and without Variable Frequency Drive (VFD). Other smaller systems were assessed and their results have been presented in other complementing reports. Evaluated technologies were assessed based on Cost of Conserved Energy (CCE), Net Present Value (NPV) and Internal Rate of Return (IRR) using a generic spreadsheet model.

The evaluation of the proposed energy efficient technologies was undertaken for two scenarios, namely, (i) replacement of old technologies with new technologies, and (ii) purchase of new technologies for new installations.
