The owner of a local B&B has been slowly improving the energy footprint of his business and recently mentioned to me that he is thinking of trying to track energy use per guest. He notes that there are other metrics related to guest stays. Like any business, there are the fixed costs of running a business, such as heating and lighting the common areas and keeping guest rooms at some minimum temperature, and then there are the variable costs associated with each guest for each night of stay. The variable cost of fuel can have a notable impact on the bottom line. Presently, all of his rooms have their own propane space heater. The thermostat is turned down when a guest leaves and turned back up when a new one is to arrive.
Has anyone had any experience with trying to track energy use per guest per night?
