Developed under the Caribbean Clean Energy Program (CARCEP), this web-based tool benchmarks hotel energy and water usage, compares energy usage with similarly operating hotels in each Country, and highlights ways to save money by putting in place energy and water efficiency opportunities.
Benefits of this tool include:
On-site energy audits provide in-depth customized analyses and reports on a hotel's operational status at one point in time. Unless another audit is performed at a later date, a one-time energy audit will eventually become obsolete once the hotel's operations or equipment changes.
This tool allows hotels to quickly asses their energy and water usage before deciding whether to move forward with an on-site audit. The tool also allows hotels to monitor their energy and water usage and costs, and update the model using these newer data points at a later time.
The tool is meant to provide visibility into what types of efficiency measures should be considered at a hotel. It is not meant to replace on-site audits.
Yes, because this tool can enable a hotel owner to see updated efficiency recommendations if the energy audit becomes obsolete.
This tool also allows hotel owners to compare their energy and water usage intensities with other similar hotels.
eQuest is a modeling tool that is able to model energy usage with much more accuracy than this tool. However, the use of eQuest requires proficiency with the software and is not meant for use by typical hotel owners or front-end staff. U.S. EPA's Portfolio Manager allows for monitoring of utility usage over time but does not provide customized recommendations for efficiency opportunities.
The tool asks 100-200 question about a hotel's construction, equipment, operating conditions, and occupancy. The tool then uses the input data to model energy and water usage.
The question are designed to be easy to answer and do not require an energy audit to be performed prior. Users are required to collect two year's worth of monthly utilities usage (electricity, LPG, Diesel, water, etc.) and costs from utility bills.
The Energy Benchmarking Tool is developed under the Caribbean Clean Energy Program (CARCEP) and is a USAID-funded activity implemented by Deloitte Consulting LLP.
The tool models energy and water usage from the bottom up by calculating electrical, thermal, and water demands from major lighting, HVAC, and kitchen equipment within the hotel. Based on inputted historical utility data, the tool then calibrates the modeled energy and water usage to match historical data. Thus, the modeled data is "trued-up" to match historical utility data.
The questions are designed to be able to be answered by a combination of the hotel owner, facility manager, and front-end staff. There is no need to have an on-site energy audit
This tool is free to all CHTA members.
The tool uses historical weather data, taken from 30-year historical hourly averages (also known as 8,760 TMY data) to estimate heating and cooling requirements. This data has been accessed from Accuweather's historical data profiles for 19 out of the 28 countries in the Caribbean. Since data is not available for the remaining 9 Caribbean countries, data was filled in with the country whose data was available and who is closest in proximity to that country whose data is missing.
Air temperature gradients or air temperature bands are bins of hours in a year that are separated into 5 degree Fahrenheit bins. If you took the average temperature for each hour in a hour, and you counted the number of hours in a year that the temperature was in that gradients band (e.g., 70-75 F), this count would represent the total number of hours in the year when the temperature was within the temperatures of that bin. This information is used to more accurately estimate annual cooling requirements instead of monthly, weekly, or daily average air temperatures.
The tool allows you to specify "suites", customizing the room size and lighting and HVAC operating conditions. In addition there is "other" common area space that can be customized for any additional areas (e.g., villas, shops, etc.)
For multiple pools, add the total square footage of each pool together to model one large pool. Do the same for restaurants/bars.
