## Achievement: A National First in the Building Maintenance Industry
Founded in 1965, Rose Bill Service Co., Ltd. (Koriyama City / President Yukiharu Endo) provides building maintenance, security, and building preservation services with a motto of sincerity in heart and technology.
Marking its 60th anniversary, the company took on the challenge of transforming its headquarters into a ZEB (Net Zero Energy Building), a standard recommended by the Ministry of Economy, Trade and Industry, the Ministry of the Environment, and the Ministry of Land, Infrastructure, Transport and Tourism. This initiative simultaneously achieves energy cost reduction and decarbonization.
They successfully achieved 'ZEB' (ZEB rate of 100% or more), meaning virtually zero primary energy consumption (zero fossil fuels) based on design—a feat considered difficult for existing buildings. The decision to take on such a high hurdle reflects the company's core beliefs.
### A Remarkable Feat: ZEB via Renovation of a Private Sector Existing Building
ZEB refers to a building that balances improved energy-saving functions with renewable energy creation to bring primary energy consumption down to zero or less. The highest rank, 'ZEB' (Kagi-ZEB), is awarded when the balance of energy consumed vs. energy generated is 0% or lower.
Rose Bill Service's renovated HQ achieved a rate of 105%. There are only 20 publicized cases nationwide—and only 2 in the Tohoku region—where existing buildings were renovated to achieve 'ZEB'. Rose Bill Service is the only building maintenance firm among them. Including public offices, achieving 'ZEB' through the renovation of a private-sector existing building is an extraordinary accomplishment.
The renovation, supported by Energier Co., Ltd., introduced high-efficiency air conditioning, total heat exchangers, solar power generation, storage batteries, and energy management systems. Battery levels and CO2 concentrations are managed automatically, maintaining a gentle indoor environment while ensuring a smart system that maintains workability without worrying about environmental impact or costs.
### Enhancing BCP for a More Secure Support System
While ZEB offers benefits like lower environmental impact and reduced utility costs, the company focused particularly on 'Improving Business Continuity in Disaster Times.' A ZEB capable of self-sufficient energy can maintain operations close to normal levels even when infrastructure is cut off during emergencies. After experiencing flooding during Typhoon 19 in 2019, the company realized the vital importance of BCP/BCM.
With approximately 500 employees, each an essential worker supporting client activities and city security, a base that ensures communication during emergencies is indispensable. President Endo stated, 'Our conviction is to protect our customers' safety and security. We will continue to strive for higher trust so that they can entrust us with their business at any time without anxiety.'
### A Symbol Transmitting Rose's DNA to the Future
Having achieved this difficult ZEB challenge, the company's next goal is fostering high expertise. As business with global companies increases, IT security standards are rising. Their mission is to constantly update skills as professionals. However, looking back over 60 years, Endo emphasizes that 'people are the protagonists of the work.' A story of an employee cleaning a hospital and giving energy to patients remains a point of pride. The ZEB headquarters will stand as a symbol to pass this 'Rose DNA'—warm, reliable service—to the next 60 years.
