LODGING

Every year, the Lodging sector spends more than $7 billion on energy. You can reduce your facility’s energy use by taking advantage of our program to upgrade to energy efficiency with no upfront costs and little to no effect on your budget.

Some of the upgrades we provide are:

UPDATING LIGHTING

Lighting represents almost a quarter of all electricity consumed in a typical hotel, not including its effect on cooling loads. Lighting retrofits can reduce lighting electricity use by 50 percent or more, depending on the starting point, and cut cooling energy requirements by 10 to 20 percent as well.

The Lodging sector has made great strides in updating lighting. However, with over half of its floor space still using fluorescent bulbs (the most recent data available), there is much work to be done:

Per energystar.gov, replacing these fluorescent bulbs with new LEDs can lead to significant savings. LEDs can be up to 40% more efficient than fluorescent bulbs and 90% more efficient than incandescent.  Since LEDs run “cool” they don’t heat the ambient air like other bulbs, thus they decrease the load on cooling systems.

Despite LEDs’ substantial energy savings over time, many facilities have been hesitant to upgrade because of high upfront costs.  Additionally, swapping out bulbs over time is not an option due to the variable lighting characteristics of the different bulb types; their colors and intensities clash.  Not a good look when you are trying to impress guests.  

UAPG allows lodging facilities to upgrade to energy efficient lighting systems painlessly with no upfront cost and little to no effect on budgets.

INSTALLING VARIABLE FREQUENCY DRIVES

Larger lodging facilities can often benefit from installation of variable frequency drives. Variable-frequency drives (VFDs) are systems used to control motor speed and torque. These drives provide precise electrical motor control so that motor speeds can be throttled to use only the energy required, rather than run at inefficient constant speeds regardless of demand.

The main function of a VFD is to affect a reduction in energy usage. The U.S. Environmental Protection Agency estimates that installing VFDs can result in 52 percent average annual energy savings. Since the horsepower required to run a fan or pump is a multiple of its motor speed, an overall 20% reduction in speed can yield energy savings of 50%. Additionally, maintenance costs can be reduced since lower operating speeds result in longer life for components.

Application options for VFDs include:

Large hotels operate around the clock, making them good VFD candidates.  However, variable frequency drives are not a good choice for every application. Our engineering partners can determine where VFD installation will be most effective, and do so with no upfront costs to you.

ENERGY EFFICIENT MOTORS

According to the Department of Energy, a NEMA-rated premium efficiency motor is 2 to 9 percent more efficient than a pre-Energy Policy Act of 2005 standard motor and 1 to 3 percent more efficient than newer standard motors. Although the potential savings for updated HVAC systems are less dramatic than for lighting and variable frequency drives, a 1 percent efficiency improvement on a new standard 100 hp motor serving a 24/7 CAV system and operating at 75 percent load could reduce hospital energy use by about 5,000 kWh annually.

OCCUPANCY SENSOR INSTALLATION

Occupancy sensors detect the motion of room occupants, turning off lights in unoccupied areas and turning them back on when movement is detected. Occupancy sensors save energy and also help to reduce maintenance costs.

In common-area restrooms, ceiling-mounted ultrasonic occupancy sensors detect occupants around partitions and corners. For hallways, a recommended strategy is to use a combination of scheduled lighting and dimming plus occupancy-sensor controls after hours. Guests do not like a totally darkened hallway, so dimming lights in unoccupied hallways and stairwells and then turning them up to full brightness when someone enters is a sensible approach. Occupancy sensors are also appropriate for meeting rooms and back rooms.

HVAC SYSTEMS

Heating and cooling represent almost 40 percent of the electricity and more than half of the natural gas used by hotels and motels. Upgrading common-area heating plants and guest-room units to energy-efficiency can result in significant cost savings.
