Integrated retrofitting strategy for enhanced energy efficiency in a tropical building.

Author(s) : SEKHAR S. C., PHUA K. J.

Summary

The paper reports the authors' findings from a study in an institutional building complex in Singapore with significant load diversity, aimed at improving the energy efficiency of a conventional chilled-water plant during a retrofitting activity. An energy simulation programme was used for the evaluation of different energy conservation opportunities, preceded by an initial exploration involving validation of the computer model with historic energy use through a comparison with actual energy data. The concept of an integrated retrofitting strategy was used and was aimed at optimizing component performance by a combination of different strategies. Retrofitting techniques for an old or conventional chilled-water plant that relies on minimization of cooling demands and optimization of equipment can achieve a roughly 40% reduction in yearly energy use over chilled-water plants. A further retrofit of the old equipment with energy efficient chillers and motors with VSD control will yield up to 51% energy conservation.
