With the evolution and widespread use of IoT devices, the technology needed to advance energy calculation methods is now at hand. The smart hotels that have the most success with verified energy savings are those that have a wealth of relevant data from their property to enable the use of the Simulated Baseline Approach. This is the more advanced of the two methods suggested by the IPMVP. This baseline model directly measures several key environmental variables which are then used to simulate energy consumption patterns that are unique to each hotel’s rooms.
Unfortunately, the Simulated Baseline Approach is still rarely seen in the industry due to its complexity to execute. Many energy management solution providers exclusively use the traditional approach because it’s logistically much easier and far less costly to create a baseline model using existing historical data. In contrast, the Simulated Baseline Approach often requires a provider to install expensive equipment to continuously collect a multitude of new data variables to build an up-to-date model that closely predicts the true baseline energy consumption of a hotel’s rooms so that it can then be compared with a hotel’s current room energy usage.
