• Compared to hard-wired systems, this system costs 70% less to install  in existing buildings, 
  and 15% less in new construction. When installed, it provides about 40% energy savings.
• This technology is used in over 100,000 buildings worldwide.

Energy-efficient automated building energy management

For the user to receive a substantial financial advantage from lowered energy use when automating a building the expected return on investment is certainly a deciding factor. If the investment or implementation costs eclipse the expected savings potential, then the technology being used will not make sense. Using technology that uses no wires, no batteries and has no limits in automated building energy management, results in an enhanced bottom line. We employ energy converters instead of batteries in our approach, cutting system error rate and maintenance costs considerably – especially in large installations.

Here is how it works in a hotel

When a hotel guest enters the guestroom, the wireless occupancy sensor recognizes that the room is occupied and initiates a signal to be sent to the HVAC controller (thermostat) in the room and other items you would like to automatically control indicating that the room is now occupied.  Then the HVAC equipment will adjust the room temperature, and power is restored to all lights and equipment in the guestroom and bathroom as programmed.

When the guest leaves the room, the occupancy sensor recognizes that the room is unoccupied .  This will send another signal to the control points in the room indicating that the room is now in “unoccupied” status.  Each item will act accordingly: lights will be turned off, and the room temperature is set back as programmed.

Alternatively, the system may be set up such that instead of the occupancy sensor, upon entry, the guest simply places the guestroom entry keycard into the card reader/holder that we install inside the guestroom near the door, and upon exiting, he/she will retrieve the keycard on the way out. This arrangement is widely used in Europe currently, and gaining popularity in United States.

Other wireless components can monitor balcony doors and when the door is opened it can turn the HVAC equipment off until the door is closed again.

We have other types of wireless sensors, relays, controls, actuators, etc. to automatically manage the energy use in all of the guestrooms individually. 

In the same manner, other parts of the property can be automatically monitored and managed. All functions in each building are programmed according to the requirements of the building operator.

Implementation has its Federal tax benefits too

If you complete the building energy management system before the end of 2013, you can qualify for significant Federal tax benefits specific to efficient energy use.  For more details please contact us.

Return on Investment

The system generally pays for its costs in 12 to 36 months. Not a bad ROI.
