Guestroom Energy Management System

EMS Thermostat

The EMS project involves adding the amenity of a guest
room wall-mounted digital thermostat that also contains
energy management (EMS) capabilities. To date, we have
146 hotels with EMS systems installed.
What are the attributes of a Hotel Guestroom Energy
           Management System (EMS)?

  The Energy Management System (EMS) provides the hotel
   guest with the amenity of a wall-mounted “Smart” Digital
   Thermostat that utilizes advanced process logic to
   accurately control guestroom temperature.

  A state-of-the-art passive infrared sensor is incorporated
    directly into the Thermostat design. The technology was
    developed specifically for hotel applications to sense the
    presence of people within the room, in order to reduce
    energy waste by setting back the temperature of the room
    when it is unoccupied or unsold.
Why utilize an EMS to reduce energy costs?

 The EMS provides a proven solution to reduce energy costs
   while having a minimal effect on guests and staff; no disruptive
   installation, or expensive, large-scale training of staff.
 The EMS also presents opportunities to enhance the guest
  experience, contribute to customer retention and brand loyalty.
 The leading EMS manufacturers have installed EMS in
  approximately 600,000 hotel guestrooms in every market
  segment from full size to mid-scale and luxury to economy
               (EMS Installations)

 Energy Management Systems were initially installed at 17
  LaQuinta properties in California as a pilot project. The
  installations were completed in April 2002.
 Two leading EMS vendors and their products were chosen for
  the CA test. Although the technologies for both vendors were
  similar, they utilize two different network architectures for
  communication back to a network server at the property. The
  vendors were also evaluated for their overall installation
   capabilities, technical support, and “after-purchase” customer
 Originally, a 10% savings from the EMS(s) installed in
  California properties was projected. The reported savings for
  the CA EMS was approximately 15% on average.
 Since 2002 LaQuinta has expanded Energy Management to
  more than 146 corporate owned and managed hotels
  How can an EMS reduce hotel operating costs?

 A significant proportion of hotel expenses is energy. One of the greatest
  wastes of energy and cost in a hotel is from guests leaving lights, heat, and
  air conditioning on when they are not in a room.
 A series of calculations performed using historical models, hotel occupancy
  data, 30-year average degree-day data for heating and cooling, and
  temperature control strategies for rented, un-rented, occupied, unoccupied
  room status, projects the average overall annual electric savings to be
  approximately 15 percent for the applicable LaQuinta Inn & Suite
 Energy dollars saved utilizing EMS will vary by several factors:
  geographical climate, hotel occupancy and energy costs.
                        Additional EMS Benefits:

   Increased Employee Efficiencies. Housekeeping and maintenance staffing
    uses the EMS to avoid unnecessary guest disturbances by accurately knowing
    whether or not the room is actually occupied.
   Reduced HVAC Maintenance Required. Maintenance reports pinpoint HVAC
    units that are not operating properly long before a guest might ever complain to
    the staff.
   Reduced HVAC Runtime Extends Equipment Life. HVAC equipment run
    time is reduced, resulting in an extension of the life of the HVAC equipment by
    an average 30-35%.
   Guest Satisfaction Index. When the guest is in the room they control the
    room environment from a conveniently located and accurate digital wall
    mounted thermostat, similar to their home environment. They control the room
    temperature precisely rather than guessing on the existing HVAC controls
    located on the unit itself.
   Night Audit Tool…Occupied versus Rented Room Status. Utilizing the on-
    line system hotel management can make a quick comparison of occupied
    rooms that are listed as . unsold rooms. This enables Management to identify
    unauthorized occupancy without having to check individual rooms.
                         EMS Installation Process

 In an effort to execute a structured process and ensure success in the
    installation of the energy management systems we developed the
    following plan of action:

The installation plan is broken into four structured segments as follows:

   1. EMS introduction overview, property survey, and rebate identification
   2. INNControl network installation and introductory property training
   3. Guestroom Thermostat installation
   4. Commissioning, final training and acceptance
 Monitoring EMS Performance and $avings

 In order to ensure optimal performance and benefits, the EMS system
   will be monitored daily via the high speed intranet connection at each
   property. If a discrepancy or operational problem is found designated
   individuals at the property and LaQuinta will be notified via electronic
 Project Management includes determination of savings to be derived
   by LaQuinta from implementing an EMS system at each applicable
 Energy Savings were measured as kilowatt-hours (KWh) saved,
   against the previous baseline 12 month period, regardless of degree-
   days, occupancy, cost per KWh or other factors except where the
   change is greater than + or – 10% of either occupancy or degreed-
   days or both. This savings estimate would not include additional
   savings associated with extended equipment life, on-line HVAC
   performance diagnostics, reduced maintenance costs or “other”
   operating benefits.
    Keys to a Successful EMS Program

   Management “Buy-In” and Commitment
   Product Application and Sustainability
   EMS Project Management
   EMS Training
   EMS Monitoring
   Information Management
   Quality Assurance
   EMS Support Infrastructure
                EMS Support Infrastructure

Program components include:
   Inn level training during the installation and commissioning of each
    property where EMS is installed; training focused on basic installation
    of the EMS, HVAC service or replacement, and obtaining useful
    management reports from the system.
   Coordinated efforts with our Purchasing Dept to ensure EMS
    equipment ordered simultaneous
   Created installation/troubleshooting video for properties to use for
    new maintenance staff or refresher for existing maintenance staff
   Trained Construction Project Managers on EMS install and operation
   Trained Company Support Desk how to handle EMS Troubleshooting
   Trained Company Telephone Support on EMS install and phone
   Identified regional maintenance personnel that could be certified as
    regional EMS specialists by attending more intense training (e.g, floor
    bridges, riser bridges,…) by manufacturer or 3rd party contractors
What Can Government do to Help
The federal government and Congress can help by:
  Including a public benefits fund in electric utility restructuring legislation to
   support efficiency programs.
  Increasing funding for Energy Star and other efficiency programs at the
   Environmental Protection Agency and the U. S. Department of Energy.
  Enacting tax credits for businesses that meet year-over-year energy
   conservation reduction targets

State and local governments can help by:
  Creating public benefits funding for energy efficiency in utility deregulation
  Working with the federal government, private industry, and utilities to
   promote Energy Star and other efficiency programs.

Utilities can help by:
   Providing both energy efficiency and conservation Rebate incentives.
   Promoting air conditioner service and testing programs to bring existing
    systems up to par
   Assisting Customers with M&V of energy efficiency efforts and technology
   Offering load control incentives to customers.
   Investigating the possibility of establishing service rates for customers that
    invest in consumption and demand reduction technologies
