Abstract
Hyatt Hotels Corporation is currently
implementing an enterprise-wide Energy Information
and Utility Monitoring System (UMS). New Horizon
Technologies and eComponents Technology have
teamed to provide an integrated solution that will
ultimately include all Hyatt Hotels in North America.
In addition, these 120 Hyatt Hotels participate in a
monthly web-based energy benchmarking and hotel
engineering reporting system. For hotels with Utility
Monitoring Systems (UMS) installed, energy and
water consumption data is automatically summarized
for the web reports. Hotels without the UMS enter
monthly utility data manually on the website.
The base UMS at the hotels consists of electric,
gas and domestic water consumption and local
temperature and relative humidity measurements.
The Hyatt UMS is one of the first enterprise-wide
systems to include domestic water metering. Many
hotels elect to install additional sub-metering for
major loads or end uses such as chillers, kitchens and
laundries.
The local hotel UMS consists of a data
acquisition system capable of displaying real-time
data that also logs 15-minute interval data. The
system transfers interval data daily, to a data center
and also transfers interval data hourly, via a Local
Area Network, to an on-site workstation with a local
database. The local workstation permits users to
have real-time alarming capability, access to easy-touse
data visualization and analysis tools, and the
ability to generate both customized and standard
daily and monthly reports. Report writing and utility
costing software are used to generate daily and
month-to-date cost reports. Bill estimation software
uses actual utility rate tariff models to create
estimates of utility costs for any custom defined
period.
Data resident in the Hyatt data center is
accessible to the individual hotels using a web-based
system. Senior engineers with authorization can
access data for all Hyatt Hotels in their regions. The
corporate energy director and senior management
have access to all data in the Hyatt data center.
Browser-based hotel benchmarking data is also
available through a similar system with an
authorization hierarchy.
This paper will describe the design and
implementation of the Hyatt UMS in detail, review
how the system is currently being used by Hyatt
personnel, discuss potential future applications and
provide an initial look at UMS system-wide data,
including a preliminary return on investment (ROI)
analysis.
