Mapping of the energy efficiency (EE) potential in cold use applications in the commercial and industrial sectors in Seychelles, on behalf of the Indian Ocean Commission (IOC). Cold uses include cooling and refrigeration in food industries and commercial installations (supermarkets) as wells as cooling systems in hotels.

Motor driven systems consume a significant percentage of electricity produced. Potential for energy savings is high. The current work presents a tool which addresses one of the most important barriers in the penetration of efficient systems, namely the lack of comparative information to help the consumer. The decision support tool was developed to analyse motor driven systems, including motor drives, pumps, compressed air systems and heat pumps used in industrial and tertiary installations. Depending on the motor system and the information available, the approach taken was analytical or database driven. The paper presents the components of the tool, discusses the advantages and disadvantages of the approach taken for each system. It finally presents the acceptance of the tool by the end users and the manufacturers of electric motor driven systems.

Electricity consumption in the tertiary sector is still increasing – by 3 % per year between 1995 and 2005 in the EU- 25 countries – and a further increase is expected of more than 2 % per year over the next 15 years. The tertiary sector includes companies and institutions of public and private services with very heterogeneous economic and energy-related characteristics. A study of the current state of data in the tertiary sector in European countries revealed that the availability of disaggregated data on electricity consumption and its use by purpose (lighting, office equipment, ventilation, air conditioning, etc.) is poor. Building managers and decision-makers are not well enough informed about the electricity consumption structure and electricity-saving potentials.
