Enermetrics completed a study of 2101 hotels across all 50 states to identify energy solutions that focus specifically on cost reduction while also addressing carbon reduction. A range of technologies were simulated and the results are shown in these bubble charts. Each bubble represents a scenario (technology for a specific hotel). These bubble charts allow us to quickly compare various technologies at specific facilities to each other and identify those that have the best financial and environmental performance. The capital efficiency can be shown by considering the capital vs financial savings. This shows that for any given capital investment, what level of savings can be achieved. Consider the orange vertical line. For an investment of 0.45M we can implement the solar (yellow), fuel cell (blue) or CHP (purple), but the CHP generates significantly higher savings and is more desirable. Similarly, consider the horizontal orange line. In this case we could implement a number of technologies to achieve $8M in savings, but the small purple (CHP) project has much lower capital requirements. The red line represents the “efficient frontier”. The closer you are to this line, the more capital efficient are the projects. If you are considering investments in energy for you facilities, we are here to help.
