CSR

The Fujitsu General Group's business concentrates on the air conditioners, information and communication systems, and electronic devices sectors, and has made great progress. And, we will continue to promote sustainable management with an eye to the future, 10 years, 20 years, and beyond, without pursuing only short-term results, and aim to become a corporate group that contributes to the realization of a comfortable, safe, and secure society through the creation of new value.

In Europe, room heating is based on radiator and floor heating which runs off of a central hot water supply, with approximately 80% of the domestic energy consumption represented by room and water heating.

Unlike conventional radiators and underfloor heating systems, ATW (heat-pump^*1 hot water heating system) is and environmentally friendly and energy-efficient hot water heating equipment. It does not use fossil fuels as it produces hot water using a heat pump system that extracts heat from the atmosphere and circulates it through pipes to heat the house. For this reason, in recent years, subsidies for construction have been developed by the French government and other countries in line with their decarbonization policies.

ATWs employ highly efficient heat pump technology and can be operated without GHG emissions. They are also safe, comfortable, and efficient hot water systems. We predict that the demand for ATW in the heating market will grow significantly in the future as the shift from combustion heating equipment using fossil fuels progresses further, and in April 2022, we established a new division dedicated to the development of ATW, the "Chilled / Heated Water Air Conditioner Development Department."

Establishing the new division will accelerate the joint development of the Water Stage, a more efficient heat pump ATW based on DC inverter technology for air conditioners, and expand the product lineup through prompt communication with Atlantic, a French air conditioner manufacturer that we have been working with in joint development since 2009.

In recent years, the demand for air conditioners in cold climates has continued to grow due to progress in the high degree of airtightness and thermal insulation of houses, advanced safety of temperature control through indooroutdoor heat exchange without combustion, and increasing demand for cooling in the summer. Furthermore, replacing fossil fuel-based heating equipment is expected to reduce GHG emissions and grow in the future from the perspective of the SDGs as sustainable heating that contributes to the realization of a sustainable society.

Under such circumstances, Fujitsu General Group launched in November 2021 in Japan the "Gokudan nocria" ZN series, heating-enhanced air conditioners for cold climates that realize the industry’s top-class heating capacity^*1 and high energy-saving performance^*2 and warm the temperature underfoot at a maximum of approximately 40°C^*4 with hot air of up to approximately 60°C^*3.

In May 2022, Fujitsu General, in collaboration with Kobe University, developed “Sound Improvement Algorithm For Outdoor Loudspeaker Stations” (hereinafter referred to as “SIAFOLS”), a technology that automatically converts the broadcast sound of Municipal Disaster Prevention Radio into an easy-to-hear format according to seasonal and weather conditions such as heavy rain and noise conditions.

The transmission characteristics of sound vary depending on the season, weather, and surrounding environment. Municipal Disaster Prevention Radio provided by local governments across Japan was faced with a problem that, although the broadcasting sound was heard, the actual details of what was being said could not be recognized. SIAFOLS is a new technology^*1 that converts generally inaudible sounds (k, s, ts, etc.) into easily audible sounds by applying an "emphasis algorithm" to them.

Fujitsu General OS Technology Limited is working to help solve the current shortage of human resources in Japan while taking into account the need for achieving a work-life balance in the food service industry.

The company also provides hospital smart outpatient information systems to help improve patient service.

Business Support BPO^*1

After streamlining and standardizing non-core operations (that do not produce profits directly) throughout the customer’s business, we create a standard manual that allows our staff to carry out these operations on behalf of the customers. Customers are able to shift their in-house human resources to focus on corporate growth or core business without worrying about securing human resources for non-core business.

In conjunction with a smartphone app, we provide mobile services that are more accessible to patients visiting hospital. Before the introduction of this service, patients had to stand-by in the waiting room of a hospital until their consultation. However, with the introduction of this service, patients will be notified by app when it is time to see the doctor, allowing them to see the doctor smoothly without having to stand-by in the waiting room. It also helps to reduce congestion in the waiting room.
