Reduction of Peak Power at Factory

At Yamaha Fine Tech Co., Ltd., power consumption was reduced by efficiently managing air-conditioning and sprinkling water on the factory roof during the period of peak power consumption. In fiscal 2015, a summer system (July-September), whereby the start time is moved two hours ahead to 6:00 a.m., was introduced for the automobile interior parts painting process where the air-conditioning load is high. Through these measures, the peak power point was shifted from 2:00 p.m. to 11:00 a.m. Compared with fiscal 2014, peak power consumption was reduced by approximately 310kWh in the hotter part of the afternoon, and power consumption by 200,000kWh during the three-month period. Moreover, improved labor efficiency enables the company to save electricity by shortening facility operating hours.
We will continue efforts to reduce power consumption through a range of measures, such as reducing the number of air-conditioning and heating units required, by reviewing workplace layout the use of steam during the winter.

Initiatives at Offices

Key Measures to Conserve Electricity

Efforts included reducing the amount of lighting (after examination of luminance), introducing LED lighting, turning off advertising lights, suspending elevators and notifying employees of power consumption to raise awareness.

The Move to LED Lighting

The Yamaha Corporation headquarters saved 24,600kWh of power per year by replacing approximately 200 florescent lights and mercury lamps with LED lighting in offices between fiscal 2014 and 2017. In fiscal 2015, the Yamaha Toyooka Factory saved approximately 44,000kWh by changing outside lighting to LEDs. Moreover, in fiscal 2017, 1,100 units of indoor fluorescents lights were changed out to LED lights, resulting in a power savings of approximately 15MWh per year. Further efforts will be taken to systematically install more LED lighting in factories and business sites in the future.

Implemented "Cool Biz" and "Warm Biz" initiatives (since 2005)

Summer (May to October): Encourage light attire such as no necktie and set air conditioning temperature to over 28°C
Winter (November to March): Wear warmer clothes so as not to rely too heavily on heating equipment and set temperature of heaters to under 20°C

Initiatives in Logistics

Saving Electricity and Reducing CO2 Emissions in Logistics

The Yamaha Group is working to increase energy efficiency and reduce CO2 emissions in logistics operations. Guided by a basic policy of raising transport efficiency, we continually review transport routes, adopt routes that incorporate more efficient modes of transport, raise container loading ratios, streamline loading sites and warehouse facilities, and conduct joint transport with other companies. Efforts are also being made to reduce CO2 emissions by disposing of waste locally and switching from air to sea for international shipping.
The Yamaha Group’s total domestic transport volume and CO2 emissions in fiscal 2017 remained about the same compared to the previous fiscal year, reaching 1,891 million ton-kilometers, while CO2 emissions also resulted similar to last year’s figures reaching 2,862 tons.
Reducing CO2 emissions from logistics requires the cooperation of transport companies, so we are working with them to develop appropriate systems by requesting transportation companies we work with to cooperate in environmental efforts and incorporating environmental matters into questionnaires.

Reduced Resources and CO2 Emissions in Piano Frame

Previously, Yamaha used disposable iron packing racks when transporting piano frames from Japan to Hangzhou Yamaha Musical Instruments Co., Ltd. To eliminate this waste, we are gradually introducing returnable packing racks for piano frames that can be used multiple times.
We completed the transition to returnable packing racks for pianos bound for China in fiscal 2012, and for Vietnam-bound pianos in fiscal 2014. Other initiatives included shortening the transportation route and improving load efficiency. These efforts resulted in a 100-ton reduction in CO2 emissions associated with the disposal of iron packing and a 1,600-ton reduction in iron resource consumption for the year. Going forward, we will examine the possibility of shortening transport distance and reducing disposable packing materials, including for parts aside from piano frames.

Conserving Resources and Reducing CO2 Emissions by Standardizing Packing Materials for Shipping Components and Materials

The Yamaha Group designs and standardizes packing boxes according to container size used in transportation, thereby improves the loading ratio of the container. This has let us reduce the number of containers used and eliminate 3 tons of associated CO2 emissions a year. The Group has also cut down on paper resource usage by designing packaging that uses as little cushioning and other packaging material as possible.
Our assumption is that the supply of materials and components from overseas locations to Japan will increase. Therefore, we first designed the standard packing boxes for piano components that can be used between China and Japan, and we are conducting validation for its practical use.
