Before speaking about new technologies, I would highlight the fact that there is a huge need to monitor the consumptions (water and energy) AND to analyze these data AND to benchmark the results. I'm auditing many hotels where they collect tons of information from different sub-meters but there is no one in charge of looking deep into these data and "translate" them. It would make sense to switch from one technology to another only if there are clear indicators to decide where to start first.

Apparently, in tropical countries chillers and all the HVAC systems are the most consuming equipment. But what do we really know about it? Without monitoring, data analysis and benchmarking it's almost impossible to make an accurate decision.

Please, dear General Managers and hotel Owners, take some time to look at these data, not only from the financial point of view but also from the resource perspective. Think about how to reduce these consumptions, especially in a time where, in some regions of the world, water shortages are going to be the next business threat.
