Today, we take you inside The NOVA Expo 2026 Re Build, an exhibition on building technology and sustainability, held from June 3–5, 2026 at BITEC Bangna Hall 103. The theme is Re Build – Upgrading Today for a Net-Zero Future, focusing on transforming old buildings to achieve a tangible low-carbon future.

This event is not just a showcase for products and innovations; it reflects a new direction for the Thai building industry at a time when the world is prioritizing energy reduction, cost savings, carbon reduction, and upgrading existing buildings to better meet future needs.

In reality, many buildings in urban areas are not entirely new constructions. Instead, the existing structures that are in daily use are crucial and need to be improved for greater efficiency in energy use, air conditioning, safety, automation systems, and building management with modern technology.

Re Build is not just about repairing buildings; it is about enhancing the quality of life in urban systems.

The heart of The NOVA Expo 2026 Re Build is to present new ideas for developing existing buildings to keep pace with the world through technologies that can be practically applied in business, industry, real estate, and building management across all types.

As energy costs become a significant burden for buildings, improving energy efficiency is no longer an optional enhancement but is becoming a crucial condition for long-term business operations, especially for office buildings, shopping centers, hotels, factories, hospitals, public buildings, and residential complexes that consume energy throughout the day.

Visitors to the event will discover Re Build solutions aimed at enhancing the efficiency of existing buildings by approximately 20–30% through improvements in building systems, the use of smart technology, and energy management design tailored to actual usage patterns.

This 20–30% figure signifies more than just reduced electricity bills; for businesses, it means long-term cost savings, improved operational efficiency, and creating new value for older buildings that may be perceived as outdated.

From old buildings to assets with new value.

One of the key points of the event is to highlight that old buildings do not always need to be demolished or replaced with new ones. With proper analysis and targeted improvements, existing buildings can be upgraded to be more energy-efficient, safer, better functioning, and more environmentally compliant.

This concept aligns with the global trend of urban development, which increasingly values maximizing the use of existing resources rather than solely focusing on new construction. Upgrading existing buildings can help reduce material usage, minimize construction waste, and lessen the carbon burden associated with new construction processes over the long term.

For building owners, project developers, and property managers, this represents a new perspective that transforms buildings from mere costs into potential assets when upgraded with appropriate technologies.

Product Launching and Innovations for Future Buildings

At The NOVA Expo 2026 Re Build, both Product Launching and the latest innovations covering various aspects of modern buildings will be presented, from energy systems, cooling systems, and automation systems to technologies that address construction site challenges and building systems.

One noteworthy technology is the High-Efficiency Cooling Tower, which is a critical system for large buildings, especially those with extensive air conditioning systems. Enhancing the efficiency of cooling systems directly impacts energy costs and is a key starting point for reducing carbon emissions in buildings.

In Thailand, where buildings are situated in a hot and humid climate, air conditioning and cooling systems are central to energy consumption. Therefore, developing high-efficiency Cooling Towers is not just a technical issue but also relates to business costs, user comfort, and the long-term competitiveness of buildings.

Smart Building & AI Automation: Making Buildings Smarter Than Ever

Another highlight of the event is the technology of Smart Building & AI Automation, which helps transform buildings from ordinary spaces into systems that can learn, analyze, and manage more accurately.

Future buildings should not merely be structures that turn on lights and air conditioning and wait for maintenance when problems arise. Instead, they should be capable of recognizing actual usage, detecting anomalies, analyzing energy consumption, and continuously adjusting systems to fit user behavior.

AI Automation plays a crucial role in reducing excess energy consumption, minimizing errors from traditional control methods, and enabling building managers to make decisions based on real data rather than mere predictions.

From a business perspective, these technologies can help buildings achieve transparent management systems, facilitate audits, and enable proactive maintenance planning, which is directly beneficial for office buildings, commercial buildings, hotels, hospitals, and industrial facilities.

Humanoid Robots: A New Role in the Construction Industry

The event also features Humanoid Robots for the Construction Industry, reflecting the increasing role of robotic technology in construction and building systems.

While the use of robots in construction may still be in its infancy in many markets today, the long-term trend is clear: the construction industry requires new tools to address labor issues, safety constraints, work precision, and on-site efficiency.

Humanoid Robots represent a vision of the future where construction will not rely solely on human labor but will integrate humans, machines, and intelligent systems to enhance safety, reduce risks, and elevate work standards.

TES Battery: A Thai Innovation for Cooling Storage

Another interesting technology showcased at the event is the TES Battery, or cooling storage system, which is a significant innovation for buildings in hot climates like Thailand.

The concept of cooling storage focuses on managing energy more efficiently, especially during peak energy usage times. Such systems can help alleviate the burden on cooling systems during peak periods and allow buildings to manage energy more flexibly.

For large buildings with high air conditioning costs, this type of technology can become a crucial tool for reducing expenses and facilitating a more sustainable energy management approach.

Modular and Prefabrication: Reducing On-Site Time and Increasing Construction Accuracy

In the construction sector, the event also presents Modular / Prefabrication technology, which helps reduce on-site time, increase production accuracy, and minimize waste from traditional construction processes.

Modular and Prefabrication construction allows certain building components to be produced in a controlled quality environment before being assembled on-site, resulting in better project management of time, labor, and quality.

In an era where construction costs fluctuate, labor is limited, and project speed is a critical factor, these technologies are becoming increasingly important, especially in real estate projects, commercial buildings, factories, and projects that require systematic quality control.

Addressing Pain Points in Building Systems with Practical Technologies

Another aspect that makes The NOVA Expo 2026 Re Build intriguing is the integration of technologies aimed at solving Pain Points in Building Systems, which are challenges that many building managers constantly face.

Whether it’s high electricity costs, overworked cooling systems, inaccurate maintenance, scattered building data, construction site issues, or a lack of tools for analyzing building performance, the technologies presented at this event are not just innovations for the sake of advancement but are practical tools that address real problems faced by operators.

This is a significant strength of the Re Build concept, as it does not start with the notion of “building anew” but begins with the question, “How can existing buildings be improved?”

Why Buildings Are Key to a Low-Carbon Future

On a global scale, the building sector is one of the highest energy-consuming sectors, with energy use stemming from air conditioning systems, lighting, elevators, water systems, cooling, electrical appliances, and space management throughout the building's lifespan.

Therefore, enhancing building efficiency is one of the crucial strategies for reducing carbon emissions at the city level and involves all sectors, from building owners and real estate developers to engineers, architects, property managers, technology manufacturers, and general building users.

In the context of Thailand, where many buildings are located in major cities and key economic zones, upgrading existing buildings to be more energy-efficient can create positive impacts on the economy, environment, and quality of life.
