The major objective of building energy management is to achieve considerable energy savings. The potential for this is quite substantial when we consider the fact that lighting alone accounts for up to 40 percent and HVAC accounts for another 40 percent or so of overall energy needs in most buildings, especially in the hospitality sector.

• 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.

Temperature and lighting controls on an individual room basis and based on the real-time occupancy status of the room are crucial in modern building energy management. Automated building energy management customized to the situation and requirement is not only a way of reducing energy costs, it also makes green sense, not to mention customer satisfaction, etc.

Our maintenance-free wireless technology that requires no batteries to change is a particularly useful approach. The simple fact that there is no re-wiring or additional wiring required makes it feasible to implement in the first place. It just makes “green” sense both in your pocket and out there in the environment. Meanwhile, it affords you superior flexibility in room configuration and any future renovations or building alterations because no added wiring is installed to. Your control, changeability, and freedom is increased while your energy costs are reduced.

We provide an innovative technology that draws its power from the energy found in its surroundings. It works without batteries, making it absolutely free of maintenance. It is easily integrated into an existing infrastructure, and is simple to operate.

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.
