In an era defined by rapid progress toward sustainability, Delta Electronics has set a new industry benchmark by transforming its headquarters building through a groundbreaking energy efficiency upgrade. The project earned the top-tier 1+ rating from the Building Energy Rating System (BERSe)—a testament to Delta’s commitment to innovation, sustainability, and smart building transformation. This revitalization of an aging structure stands not only as a technical achievement, but also as an inspiring story of green reinvention.
Retrofitting older buildings for energy efficiency presents multiple challenges. Outdated equipment often leads to poor performance and high energy consumption, while integrating new technologies into existing systems can be technically complex. The construction process itself is difficult and costly, and high upfront investment tends to extend the payback period—factors that make many owners hesitate before embarking on such a project.
To ensure a precise and effective improvement plan, Delta conducted a comprehensive energy audit, analyzing historical consumption data to establish accurate energy baselines and models. This data-driven approach identified key sources of energy waste through cross-performance comparisons. Based on these insights, Delta developed an objective energy-saving report detailing potential improvement measures, expected benefits, ROI, and implementation steps—empowering facility managers to make informed decisions that maximize long-term efficiency
To effectively achieve its energy-saving goals, Delta’s headquarters implemented a range of integrated energy efficiency upgrades. In addition to introducing high-efficiency air-conditioning systems and smart lighting controls to reduce infrastructure energy consumption, the building also adopted total heat exchangers to lessen the air-conditioning load from the fresh air system. At the same time, outdated equipment was gradually replaced with high-efficiency models, and energy recovery technology was introduced to the elevator systems. These hardware upgrades, together with the deployment of an energy management system, worked in tandem to deliver significant improvements in overall energy performance.
