[Newsletter No. 117] Rising Electricity Rates, The key to building energy saving lies in 'data'.

Hello, this is Radionode.

Held at COEX in Seoul for three days starting from May 13 HVAC KOREA ExhibitionAt [location], Radionode introduced various solutions for building energy saving.

From air quality measurement to occupancy detection and BACnet integration, many customers, especially How to save energy by linking HVAC systems with IoT sensorsYou showed great interest in [it].

In this newsletter Building energy saving solutionsIntroducing

Why is building energy management important now?

Due to the recent rise in global energy prices, the burden of building operating costs is rapidly increasing. This is particularly true for spaces that require the continuous operation of heating, cooling, and ventilation systems, such as large buildings, factories, hospitals, schools, and research facilities. Energy cost managementGo soon Operational competitivenessIt is becoming this

Most HVAC systems use additional energy to ventilate by bringing outside air into the room and to readjust the indoor temperature.

the problem is There is a lack of data to determine “how much ventilation is needed” and “whether heating or cooling is really necessary right now.”The point is that

If, through data Accurately know indoor air conditions and control only the space where people are actually present.What if you could? You can reduce unnecessary energy consumption and increase operational efficiency.

To do this, Radionode RN320 LoRaWAN Air Quality Sensor, RN370 Radar Presence Sensor, RN003 BACnet GatewayI suggest

Air quality measurement: Determines whether indoor air is fresh based on data. 

▲RN320-CDT

[Effects of RN320-CDT Application]

● Reduction of unnecessary outside air intake

● Reduction in heating and cooling load

● Maintaining indoor air quality

● Energy cost savings

● Data-driven HVAC operation

The first key to building energy saving is Accurately measuring indoor air quality.

Previously, it was difficult to accurately assess indoor air conditions, often leading to the intake of more outside air than necessary. However, this increases heating and cooling loads, ultimately resulting in higher energy costs.

Radionode RN320 Air Quality SensorIt measures various air quality data, such as CO₂ concentration. It supports determining whether ventilation is needed in the current space based on data. 

In other words, it is not a sensor that simply displays numerical values, Sensors that help HVAC systems control ventilation volume more intelligently.

Person Detection: Reduces energy waste in empty spaces. 

▲RN370

[RN370 Application Effects]

● Automatic OFF of heating and cooling in unmanned spaces

● Automatic lighting control

● Securing usage rate data by space

● Energy optimization for spaces such as meeting rooms and offices

● HVAC & Lighting Automation

The second key is Accurately determining whether there is actually a person in the space.

In meeting rooms, hallways, offices, and common areas, lighting and heating/cooling systems often continue to operate even when no one is present. This "invisible waste" is a major cause of high building energy costs.

Radionode RN370 occupancy sensorIt detects the presence of people in the space using a radar method.

Not just simple motion detection, Determining the occupancy status itselfBecause of this, it automatically reduces heating, cooling, and lighting when no one is present, and maintains a comfortable environment when people enter.

Energy savingIt is not simply about reducing facilities, Using only what is needed in the necessary spaceIt starts from .

BACnet: Connects sensor data to the building control system 

▲RN003

[Effects of Applying RN003 Gateway]

● RN320 Air Quality Sensor Data Collection

● RN370 Occupancy Sensor Data Collection

● Convert IoT sensor data to BACnet protocol

● LAN-based building control system interoperability

●Data linkage with HVAC, lighting, and ventilation control systems

The third key point is connecting sensor data so that the building control system can use it directly. 

Sensor data only becomes valuable when connected. 

No matter how good the sensor data is, it cannot lead to actual control if it is not integrated with the building control system.

Radionode's new ProductsRN003 gateway converts data from the RN320 and RN370 into the BACnet protocol to connect with existing HVAC systems. 

Through this, the BMS can receive data such as CO₂ concentration, air quality status, and occupancy in real time and automatically control cooling, heating, ventilation, and lighting.

Now, saving energy is a necessity, not an option.

Reducing building energy costs does not begin with grandiose changes, but with securing accurate data. 

Check if the indoor air is good, reduce energy usage in unoccupied spaces, and 

Connecting all measured data to the building control system.

This is the data-driven smart building energy management method proposed by Radionode.

Data-driven energy management that measures, judges, and controls.
