Prodesign was commissioned to carry out an energy assessment of the newly installed solar hot-water systems in four Sun Resorts Group hotels, as well as to determine the potential savings resulting from installing energy-efficient lighting fixtures. The savings in gas and diesel consumption resulting from the coupling of a solar-thermal system to the original hot-water production system have been determined from generated solar-radiation data over a typical year for the four hotel locations.
Reports have been produced on expected savings, as well as guidance for formulating measurement and verification (M&V) plans. The four hotels are currently in the process of implementing their respective M&V plans. The lighting energy savings analysis was carried out based on data collected by zoning the hotel sites appropriately and gathering information about current lighting installations as well as those before any changes were made.
The hotel occupancy pattern and lighting operating schedules were used to calculate expected savings. The project was started in January 2012 and is expected to be completed in November 2013.
