ISSUE

The model of Yanmar's concept to point the future in a better direction.

Yanmar head office is located in Chayamachi, Osaka, where it was founded. YANMAR FLYING-Y BUILDING, which brings together the world latest environmental technologies, is itself a conceptual model that points to the future of the buildings. It incorporates various CO2 reduction technologies such as solar thermal collectors, solar photovoltaic power generation, gas heat pump air conditioning, and gas cogeneration systems. Through active utilization of CO2, we aim to realize a zero CO2 emission building (ZEB). With 100 years of history and a vision for the next 100 years, this building expresses the practice of Yanmar's mission, Coexisting with nature and realizing a enriched life.

SOLUTION

Gathering ideas that aim to coexist with the world-leading environmental technologies and nature

YANMAR FLYING-Y BUILDING has made it possible to significantly reduce CO2 emissions by combining the latest environmental technologies with our own products and technologies. In terms of equipment, a gas cogeneration system is adopted as a heat source for air conditioning and hot water supply in offices to achieve energy savings with high combustion efficiency and low fuel consumption. In the air conditioning system, a gas heat pump air conditioner (GHP) is installed. In addition, a solar photovoltaic power generation is installed on the south wall of the building to maintain optimal energy creation for urban buildings. LED lightings are used throughout the building, and the brightness of the lighting is automatically controlled in conjunction with a sensor that measures the brightness of natural light. The Yanmar Energy Management System (Y-EMS), which control heat and power supply, is adopted to contribute CO2 emission reduction.

Efforts to coexist with nature are also incorporated throughout the building. In terms of ventilation, sunlight and wind are used effectively with eco-louvers over the glass window that reflects the sunlight and naturally ventilate air under each floor. Furthermore, on the southern wall, a greenery with a height of 52m, a width of 23.7m and an area of approximately 1,230m2 has been planted. It also contributes to the restoration of local ecosystems and adsorption of air pollutants. On the roof, we support the beekeeping activity, NPO Umeda Bee Project which started in March 2011. Bee hive boxes are set up along with 40% of the area to be covered by plants with flowers, making easier for bees to collect nectar.

In the office, a gas cogeneration system is installed for air conditioning and hot water supply. Energy savings with high combustion efficiency and low fuel consumption at the same time.

For the office air conditioning system, a gas heat pump air conditioner (GHP) is installed. It provides a comfortable indoor environment.

A solar photovoltaic power generation facility optimal for energy creation in urban buildings is installed on the south wall.

1,230m2 of greenery is planted on the south wall. It contributes to amusing visitors and users, restoring the local ecosystem, and adsorbing air pollutants.

Except for some facility rooms, LED lightings are installed every floor. The brightness of the lighting is automatically adjusted in conjunction with a sensor that measures the brightness of natural light.

Eco-louvers over the windows and natural ventilation allow the natural light and wind to be used effectively.

YANMAR FLYING-Y BUILDING supports NPO Umeda Bee Project by providing space for bee hive boxes in the roof garden. We promote activities including rooftop greening, biodiversity, and revitalizing local communities.

The Yanmar Energy Management System (Y-EMS), which control heat and power supply. It contributes to CO2 emissions reduction by automatically controlling the facility from the controller installed on the rooftop.

RESULT

Drastically reduced CO2 emissions
Highly evaluated comfort in indoor environment

The head office building, where Yanmar has gathered world-class environmental technologies, received the highest of rank S in the CASBEE Osaka Mirai *, which evaluates the environmental performance of buildings. In addition to energy and resource-saving technologies, the comfort of the indoor environment is highly evaluated. The actual value of CO2 emissions of the area in fiscal year 2018 was 54.0 kg-CO2 / m2 year. The value marks -61.7% compared to a typical building. We confirmed a legitimate effect on CO2 reduction.

* A system that comprehensively evaluates the environmental performance of buildings. In addition to environmental considerations such as energy and resource savings, and recycling, evaluations are also based on considerations such as the comfort of the indoor environment, building life cycle, and protection for the landscape.
