Smart Building Energy Efficiency Innovation: KDC BAS/BEMS Success Story
The importance of building energy management is increasing day by day. Many companies and institutions are making various efforts to improve energy efficiency and reduce operating costs, but often face difficulties due to initial system setup failures or underwhelming results. For instance, some companies experience issues such as underperformance or lack of user training when introducing their first smart building control system. In this situation, KDC supports efficient energy management for customers through its smart building automatic control and energy management systems. With extensive construction experience, especially in public institutions, it enhances technical reliability and contributes to energy savings and improved operational efficiency.
Challenges in Energy Management, The Need for an Integrated System
Many buildings face challenges in energy management due to outdated facilities and individual systems. With each system such as heating, lighting, and ventilation operating independently, energy waste occurs, making efficient management difficult. Additionally, there are limitations in accurately analyzing and predicting energy consumption data, making it challenging to establish an optimal energy management strategy. To resolve these issues, the introduction of an integrated Building Automation System (BAS) and Energy Management System (BEMS) is essential. Particularly for public institutions, achieving energy-saving goals while maintaining a comfortable indoor environment is crucial. However, during the initial system setup, issues such as compatibility problems, lack of user convenience, and maintenance difficulties can arise, preventing the achievement of the expected outcomes. Overcoming these challenges and achieving successful energy management requires selecting a partner with professional expertise and extensive experience.
KDC’s Differentiated Solutions: Integrated Control and Optimized Energy Management
KDC focuses on the development and supply of smart building automatic control and energy management systems as its core business, enhancing customers’ energy efficiency based on BAS/BEMS technology, solutions, and achievements. BAS integrates and controls major facilities within buildings such as boilers, air conditioners, lighting, electricity, and HVAC with an interface based on scafa UI. It ensures flexibility and efficiency with a controller that can be expanded to up to 160Tags, Modbus RTU/TCP communication, scheduling, and self-diagnosis functions.
BEMS monitors the energy usage status of buildings in real-time, supporting comprehensive energy management such as analysis, prediction, and cost analysis. It especially provides a foundation for sustainable management through efficiency analysis and performance management to respond to ESG management. Additionally, invert+ is an inverter-based energy-saving system that achieves 28% better efficiency in low-load environments compared to general inverters and reduces losses by up to 75% in no-load conditions, attracting attention.
It aims for optimization with designs considering site-specific energy demand and seasonal fluctuations, and its integrated control platform, scafa, supports both efficiency and accuracy in equipment maintenance and management through functions like PMS, PRC, PQMA, and MCSA.
KDC has unique technological capabilities based on various real-time control and monitoring technologies, optimizing motor control, ensuring high energy efficiency even in partial load environments, integrated BAS/BEMS operation, and an expandable design well-suited for field applications. By minimizing fixed losses with VFVD-based control technology, it achieves up to 83% efficiency in the average load factor 12% range, which allows for meaningful energy-saving effects even in actual operating environments.
The ability to perform integrated control and data analysis through a single UI system is advantageous for reducing the complexity of operational management, and the flexibility in the number of tags and I/O module configuration allows for easy system expansion to fit various field conditions. Based on this, KDC has acquired major domestic certifications like the K-Mark, Q-Mark, Procurement Excellence Product, and Green Technology Certification, alongside international certifications like UL, GS, BTL AWS/BC, and ISO, proving its high technical reliability. In addition, it continues its technology-based growth by completing patent registrations in South Korea (19 cases) as well as in the United States, China, and Japan, and acquiring T2 grade in SME technology evaluation.
Real Customer Change and Performance: Maximized Energy Savings and Operational Efficiency
After adopting KDC’s BAS/BEMS solution, customers are experiencing various effects such as reduced energy consumption, reduced operating costs, and maintaining comfortable indoor environments. Particularly in the public sector, actual facility operations improvements are being confirmed in addition to regulatory compliance.
Case Study 1: Public Institution Energy Savings Effect
One public institution utilized KDC’s BEMS to analyze energy inefficiencies and apply tailored control strategies, resulting in approximately 20% energy usage reduction. They reduced unnecessary energy consumption based on real-time energy monitoring and improved operational efficiency by optimizing HVAC system operations.
Case Study 2: Improved Indoor Environment in an Educational Facility
An educational facility enhanced the precision of ventilation and temperature-humidity control after adopting BAS, improving indoor air quality. Notably, by adjusting outside air influx through automatic control, they minimized the impact of fine dust while maintaining a stable temperature, improving the learning environment and reducing energy consumption.
Case Study 3: Cultural Facility Operating Efficiency Improvement
A cultural facility improved equipment failure rates and reduced maintenance costs by introducing the scafa based integrated control system, allowing for real-time equipment status awareness and quick response to anomalies. The integration of precision process control and power quality analysis functions contributed to operational stability.
BEMS Mandate Era, KDC’s Growth Strategy
The BAS market is forming alongside the spread of BEMS, and in South Korea, BEMS installation is mandated for buildings above a certain size, making market access easier. Accordingly, KDC is pursuing a strategy of leveraging 4th industrial-based intelligent control technology and is promoting entry into overseas public markets through domestic public procurement platforms. Furthermore, with K-certified products, it is enhancing accessibility to Southeast Asian and Middle Eastern markets and continuously developing AI prediction technology based on energy data.
Particularly, Singapore and Dubai are already implementing a BEMS mandate with the application of high-efficiency building standards. Countries like China, Australia, and Canada are either preparing legally or in pilot stages, drawing attention as future markets. KDC actively responds to these trends, seeking business expansion with products and references that align with regulatory frameworks in target countries.
KDC is exploring effective entry strategies to overseas markets centering on public procurement, based on its domestic public procurement performance. With the likely expansion of countries mandating BEMS, the energy management market is expected to continually expand. KDC’s technology and experience align with these trends, enhancing competitiveness in the smart building energy management sector.
KDC’s case demonstrates that beyond simple system supply, designing optimized solutions to fit each enterprise’s demands and facility conditions is crucial. Additionally, realizing long-term energy-saving effects through continuous maintenance and performance verification post-system setup is key. KDC will continue to lead energy innovation in the smart building market by advancing technology and client-centered services.
KDC’s successful BAS/BEMS construction experience can serve as a guide for other companies. Companies contemplating systematic energy management can achieve the practical goal of energy savings with a partner proven for functionality and technical capability. Moreover, adapting flexibly to government regulatory changes and establishing energy strategies for a sustainable future can also be a beneficial choice.
To achieve energy efficiency and operational optimization in smart building construction, the introduction of an integrated and reliable Building Automation System (BAS) is crucial. KDC, with its rich field experience and advanced technology, provides practical performance, contributing to enhanced sustainability in both public and private sectors.
