Caterpillar Saving Energy Across China

Natural Gas Conservation Project Since 2012, Caterpillar (Suzhou) Co., Ltd. has reduced natural gas consumption and contributed to greenhouse gas reduction through the innovative Natural Gas Conservation Project. This project used the residual heat of hot water pipes to efficiently send warm air to the central heating system of its office building. In the first eight months of the project’s operation from the fourth quarter of 2012 to 2013, the facility saved 116,000 cubic meters of natural gas. This project was recognized by the Suzhou Environmental Bureau and the facility is considered a role model for saving energy in the Suzhou Industrial Park.   Controlling Lighting to Conserve Energy Project Caterpillar (Wujiang) Co., Ltd. previously used more electricity than necessary for its lighting system. A Controlling Lighting to Save Energy Project was initiated in 2012 and achieved good results. For example, before the project, many working areas were lit even when people were not working in them. Beginning in 2012, the facility improved the optical automatic switch and removed superfluous lamps from working and non-working areas. Thanks to this project, electricity usage was lowered by 100,757.22 kWh in one year resulting in cost saving of RMB 84,000 (USD 14,000).   Electricity Saving Project Energy Management Center AsiaTrak (Tianjin) Ltd. initiated its Electricity Saving Project Energy Management Center in April 2012. With a total investment of RMB 1.2 million(USD 175,000), the project increased the efficiency of electrical equipment in the facility by focusing frequency-converting control of the air conditioning system and the water circulating system. Thanks to this project, the facility saved 360,000 kWh of electricity in one year as well as about RMB 256,000 (USD 37,336).   Click here to read more about sustainability in China in the Caterpillar 2013 Sustainability Report.
