Effective utilization of solar energy [Art Metal Mfg.]

Nagano-based Art Metal Mfg. and four other Japanbased Art Metal Mfg. group companies utilize the geographical characteristics of their local areas—long daylight hours and low rainfall—to engage in photovoltaic solar power generation. Making use of sloped surfaces on factory roofs and parking areas, the companies generate a combined total power output of 1.72 MW. In fiscal 2018, the group generated 2,100 kWh of power, achieving an effective reduction of approximately 870 tons in CO2 emissions.

Promotion of improvement activities through the visualization of air leakage[Aisin AW]

Aisin AW’s Shiroyama Plant (formerly belonging to Aisin AI) has mapped air leakage to clearly visualize the current state of air leakage at all of Aisin’s plants. This makes it easy to manage air leakage at each of our production sites and is contributing to various reduction activities such as the formation of more QC circles to address various points. As a result, annual energy loss caused by air leakage has been slashed by 2/3 and CO2 emissions have been reduced by 346 tons. We will continue actively working to reduce CO2 in our plants.

Awarded the Energy Conservation Grand Prize in 2018*1[Aisin Seiki]

Aisin Seiki and six other companies were awarded in the Products and Business Model category of the Special Jury Prize at the Energy Conservation Grand Prize in 2018 for Smart Multi*2, a hybrid personal air conditioning system. Smart Multi is operated by a gas heat pump (GHP) and electric motor heat pump (EHP) using IoT technology, achieving the optimal balance between the two for easy operation by the user. The system achieves energy-efficient operation and reduces energy costs in light of factors such as variance in energy prices depending on energy demand and the season and time of day.

Reducing office power usage using a geo-power system [Aisin Seiki]

At Shinkawa Plant, Aisin Seiki has introduced a geopower system that makes of geothermal heat—which remains stable throughout the year—to reduce other energy usage.

The system uses heat exchangers to cool (or heat) outside air, which is sucked down to a depth of 5m underground, and then uses fans to deliver the air to rooms in its office buildings as a form of auxiliary air conditioning. By supplementing conventional air conditioning in this way, the system achieves reductions in main power usage. Passing the air through the end of underground pipes also enables the system to deliver a clean, comfortable airflow, thereby contributing to improving the workplace environment.

Clean energy plant that has introduced renewable energy and energy-saving technologies [Aisin Seiki]

In August 2017, Aisin Seiki constructed an additional south building within the premises of its Nishio Die-Casting Plant to increase production capacity. The new building was designed to improve product quality, increase productivity, and ensure safety and a better working environment for its employees, with the aim of “achieving a world-leading die-casting plant through technological and human innovation.”

In terms of global environmental aspects, despite handling die-casting processes that typically consume large amounts of energy and emit large volumes of CO2, the new building significantly reduces energy consumption in terms of both building facilities and production equipment. As a result of these improvements, Aisin Seiki expects to reduce CO2 emissions for the other die-casting plants by over 50% in comparison with fiscal 2015.

Reducing CO2 emissions through the introduction of BDF

AISIN Group is working to reduce CO2 emissions by utilizing Biodiesel Fuel (BDF)—made by collecting and refining food oils used in employee cafeterias—in its transport vehicles.

Since 2008, AISIN Group has utilized commuter buses that transport employees between the nearest station (or employee dormitory) and the workplace during commuting hours. We currently operate two BDF buses, achieving an annual CO2 reduction of around 25 tons per year.

Additionally, in fiscal 2018, we also commenced trail operation of BDF for trucks used to transport parts and other products manufactured by AISIN Group. With the full-scale introduction of these BDF trucks in fiscal 2019, we expect to reduce annual CO2 emissions by approximately 105 tons per year (with two trucks).

In addition to reducing CO2 emissions, BDF transport vehicles make effective use of waste and are also friendly to the atmosphere. Moving forward, we will continue to further expand their use within the Group.

Developing software to achieve reductions in CO2 emissions [Aisin ComCruise]

Aisin ComCruise, which develops and evaluates control software for automobile onboard hardware and other devices, develops software for various products. In particular, the software is greatly contributing to reducing CO2 emissions at the product usage stage, in which a lot of CO2 is emitted. The company will continue to advance development of the software.

Eco Product certification

To facilitate the development of environmentally friendly products, Aisin Seiki has established a scheme whereby it selfcertifies products with superior environmentally friendly characteristics as Eco Products. In fiscal 2018, the COREMO B2 Model household cogeneration system was certified as an Eco Product under the scheme. Looking ahead, we will continue to increase the number of Eco Products and work on development that is more conscious of the global environment.

Features

COREMO can reduce CO2 emissions by approximately 1.0 ton annually, compared with conventional hot-water heaters (gas hot-water supply heaters) for use in cold regions. The B2 model reduces the volume of consumed resources by achieving approximately a 13% weight reduction from the B1 model, becoming a more environmentally friendly product.

Comment from developer

In the B2 model, we have improved the exhaust heat recovery circuit and control system for heating devices, abandoned the use of a cooling water tank for heat accumulation and significantly reduced the volume of coolant used, which presented difficulties in terms of recycling. We also sought to reduce the amount of resources consumed by advancing weight reduction of the system, such as by integrating the chassis components and engine air intake/exhaust components. As a result of these efforts, we have achieved a reduction in resources consumed while at the same time maintaining product performance.
