In commercial buildings in Vietnam such as shopping malls, showrooms, retail stores, and office buildings, air conditioning systems account for a large portion of operational costs, especially during summer. However, one often overlooked factor that directly impacts cooling efficiency is the automatic door system at entrances. Uncontrolled door opening and closing leads to continuous loss of cool air to the outside. Therefore, selecting an energy-saving automatic door solution for summer not only helps optimize operational costs but also improves space efficiency. Among current solutions, the NABCO NATRUS automatic door system combined with the NABCO NSW-A01 sensor is considered a suitable option for various types of buildings. Let’s explore why this is an optimal investment for cost efficiency and enhanced spatial experience with Sonha Auto below.
How do conventional automatic doors cause energy waste?
Most conventional automatic door systems today operate based on simple motion detection sensors. This causes the door to react to all movements within the detection zone without distinguishing user intent.
In real-world operation, this leads to several issues:
- People passing by the door also trigger it to open
- People standing near the door keep it in an open state
- The door opens unnecessarily multiple times during peak hours
For buildings with entrances directly exposed to the outdoor environment—especially under hot weather conditions—these uncontrolled openings make it difficult to maintain stable indoor temperatures. As a result, HVAC systems must operate continuously at high capacity, reducing the energy efficiency of automatic doors and significantly increasing operational costs.
NATRUS automatic door solution combined with NABCO NSW-A01 sensor
Instead of only improving the opening/closing mechanism, NABCO provides a smart entrance solution with energy-saving automatic door technology, focusing on the most critical factor: precise control of user behavior through automatic door sensors.
When the NABCO NATRUS automatic door system is combined with the NSW-A01 sensor, it delivers superior performance compared to conventional systems.
Improved operating principle
The NABCO NSW-A01 sensor not only detects movement but also analyzes the direction of movement, level of approach, and presence within the detection zone. As a result, the door only opens when users genuinely intend to enter, instead of reacting to all surrounding movements. This is the key factor that makes the system an effective energy-saving automatic door solution for summer.
Operational efficiency
With precise control over when the door opens and closes, the automatic door system becomes more than just an entry device—it becomes a key component in the building’s overall energy optimization strategy. With the NATRUS automatic sliding door solution combined with the NABCO NSW-A01 sensor, door openings occur only when users truly need to pass through. This significantly reduces unnecessary openings while optimizing the duration the door remains open.
This brings clear real-world benefits: indoor temperature is maintained more consistently, minimizing the loss of cool air to the outside.
For facilities that rely on continuous air conditioning—such as retail stores, showrooms, and shopping malls—this is a critical factor in reducing HVAC load, improving cooling efficiency, and optimizing electricity costs.
Beyond energy efficiency, reducing unnecessary opening/closing cycles also lowers mechanical stress on components such as rails, motors, and drive systems. Over time, this enhances durability and overall system stability.
NABCO NSW-A01 sensor
In any automatic door sensor system, sensor accuracy is the core factor determining operational efficiency. A high-quality door system with an insufficiently intelligent sensor can still result in mistimed openings, causing energy waste and negatively affecting user experience.
The NABCO NSW-A01 sensor is developed to comprehensively address these limitations. Unlike conventional sensors that only respond to movement, NSW-A01 can simultaneously analyze both motion and presence within the detection zone, allowing it to accurately determine user intent.
Thanks to its ability to recognize movement direction, the sensor clearly distinguishes between passersby and users actually approaching the door.
At the same time, optimized detection zones minimize interference from external environmental factors—a common issue in buildings with open-front designs. This enables the door system to operate more accurately, respond faster, and maintain stability under various conditions. This is the foundation for achieving reduced heat loss with automatic doors while ensuring a seamless and comfortable user experience.
Suitable for building conditions in Vietnam
In practice, many buildings in Vietnam differ significantly from enclosed models. Entrances are often directly exposed to the outdoor environment, with high foot traffic and hot, humid weather creating a constant temperature difference between indoor and outdoor spaces.
In such conditions, conventional automatic doors tend to remain open continuously due to being triggered by irrelevant movements—especially in busy street-facing locations.
The NATRUS automatic sliding door solution combined with the NABCO NSW-A01 sensor precisely controls these situations.
The door opens only when someone truly approaches, rather than reacting to all surrounding movements. This makes it particularly suitable for retail stores, shopping malls, restaurants, hotels, and showrooms—places that require both operational efficiency and high-quality user experience.
It can be said that this is a crucial foundation for implementing a smart entrance solution suited to real-world conditions in Vietnam, where environmental factors and user behavior are highly dynamic.

Optimizing long-term operational costs for investors
For investors and operators, system efficiency is not only about initial investment costs but also about optimizing costs throughout its lifecycle. Applying an energy-saving automatic door solution for summer with NATRUS and the NSW-A01 sensor delivers clear benefits in multiple aspects. First, it reduces electricity consumption for air conditioning systems by minimizing heat loss during operation.
At the same time, reducing unnecessary door cycles decreases mechanical wear, thereby extending equipment lifespan and lowering maintenance costs. From a broader perspective, this is not just a technical solution but also an effective investment—especially for buildings with high usage frequency and continuous operation requirements.

In practice, NABCO automatic doors have been widely applied in large-scale projects such as airports, hospitals, and shopping malls—places that demand high stability, durability, and continuous operation. When combining NABCO’s robust mechanical and control platform with the NATRUS automatic door system and NSW-A01 sensor, the solution goes beyond simple automation of opening and closing. Instead, it delivers intelligent operation, where each door movement is controlled and optimized based on real user behavior.
This combination enables buildings to achieve three key objectives simultaneously: energy optimization, enhanced user experience, and sustainable operation. This is also the inevitable trend for modern automatic door systems as operational efficiency requirements continue to rise.
