Two Solutions • Different Scenarios • IR Remote Compatible

Smart Energy Saver
for Air-Conditioning

NBE provides two aircon energy-saving products designed for different real-world scenarios. Both solutions work with air conditioners that use IR remote control, and use IR learning to capture the aircon’s ON/OFF commands.

Choose the right solution based on your space usage: steady occupancy (bedrooms) or frequent empty-room wastage (meeting rooms).

Why Aircon Wastes Energy

Overcooling

In bedrooms or long stays, the aircon may keep running even when the room has already reached a comfortable level.

Empty Room Operation

In meeting rooms and offices, people often forget to turn off the aircon after leaving, causing long periods of wasted operation.

Manual Dependence

Relying on people to switch off consistently is unreliable. Automation removes the human error factor.

Two Products, Two Different Objectives

Item Product 1: Bedroom Comfort Saver Product 2: Meeting Room Presence Saver
Best Scenario Bedrooms / long stays where users do not move in/out frequently. Meeting rooms / offices where users may forget to turn off aircon after leaving.
Primary Objective Reduce overcooling while maintaining comfort during extended occupancy. Prevent wasted operation by turning off aircon automatically when the room is empty.
Control Method IR learned ON/OFF control with NBE control logic based on research. 24 GHz radar human presence detection triggers IR ON/OFF control.
Typical Saving 20–30% typical savings in bedrooms (usage-dependent). Savings vary by “forgetfulness”; can save up to 50% in high-waste scenarios.
Aircon Compatibility Suitable for air conditioners with IR remote controls.
Product 1: Bedroom Comfort Saver

Designed for steady occupancy (sleeping / resting). The system learns your aircon’s ON/OFF signals and applies a control strategy derived from NBE research to reduce overcooling while preserving comfort.

Best for: bedrooms, small rooms, long-stay spaces.

Product 2: Meeting Room Presence Saver

Designed for spaces where occupants come and go. A 24 GHz radar sensor detects human presence and automatically switches the aircon ON/OFF based on occupancy—eliminating energy waste when rooms are left empty.

Best for: offices, meeting rooms, training rooms, shared spaces.

Meeting Room Occupancy Control Architecture

Product 2 is designed to support a wide range of occupancy-based energy saving applications. The controller can directly operate IR-controlled air-conditioners, support future wired interfaces for panel-controlled systems, and optionally control other appliances through RF relay adaptors. This flexibility allows deployment in meeting rooms, offices, classrooms, training rooms and shared facilities where equipment is frequently left running after occupants leave.

Meeting Room Occupancy Control Architecture
IR-Controlled Air-Conditioners

Learns ON and OFF commands directly from existing remote controls. No protocol database is required, making installation simple for most residential and commercial split-unit air-conditioners.

Future Wired Integration

Certain commercial air-conditioners are operated from wall panels instead of infrared remotes. Future wired interfaces can extend occupancy-based control to these systems.

Optional RF Appliance Control

RF adaptors can be added to control lighting, fans, televisions, heaters and other electrical appliances, allowing a single occupancy controller to manage multiple energy-consuming devices.

Energy Saving Highlights

Product 1 Savings (Bedroom)

In bedroom usage patterns, savings are typically achieved by reducing unnecessary runtime after the space has stabilized. Based on usage and settings, typical savings are in the range of 20–30%.

Outcome: improved comfort consistency and reduced overcooling.

Product for: bedroom savings.
Product 2 Savings (Meeting Room / Office)

Savings depend on how often aircon is left running in empty rooms. In environments with frequent “forgotten” aircon operation, the system can reduce wasted runtime significantly—saving up to 50%.

Outcome: automation prevents human error and reduces avoidable energy waste.

IR Learning Control (Works With IR Remote Aircons)

Learn

User presses a learn button to capture the aircon remote’s ON and OFF IR signals.

Decide

NBE’s embedded processor runs a control logic strategy derived from research to determine the best ON/OFF decision.

Repeat

The device transmits the learned IR signal back to the aircon to execute the command reliably.

System Architecture

A practical control chain designed for real spaces: sense → decide → transmit IR → reduce waste.

Room

Bedroom / office / meeting room

Sensing

Temperature (P1) or 24 GHz radar presence (P2)

Processor

NBE control logic strategy

IR Transmitter

Aircon Unit

IR remote compatible air conditioners

Recommended Applications

Bedrooms / Residential

Best matched with Product 1 for long-stay comfort. Achieves savings by reducing unnecessary runtime and avoiding overcooling.

Meeting Rooms / Offices

Best matched with Product 2 for occupancy automation. Avoids waste from forgotten aircon operation, especially in shared spaces.
