“Retrofit” – A Business Opportunity for Small and Medium Enterprises! ~ Recommending Retrofit ~Hirokazu Taniguchii
＜Series 2 / complete＞
In the first part, we you talk about the “Warning for the danger posed by the use and throw culture of Japanese people”, and “Relationship between retrofit and sustainable technology”. In this part, please share your thoughts on the “Benefits and challenges of retrofit”, and “Product examples for retrofit”
Advantages of “Retrofit”
“Retrofit” enhances energy-saving performance by increasing the efficiency of only the important parts in a machine. I will talk about the advantages of “Retrofit” with the example of an air conditioner of Daikin Industries, Ltd. that won the Energy Conservation Award in 2016. Replacing only the compressor and control board with higher performance parts in an outdoor unit of Daikin air-conditioner (see the figure below) in the middle of its service life, the energy-saving performance of an air-conditioner improved by 15%. There is a significant reduction in the cost compared to replacing the entire outdoor unit with a new product. The work requires less than a day, and there is no need to worry about hindering the weekday work of a building, etc. by carrying out the retrofit on holidays. This method is environmentally friendly as the amount of waste is also reduced to 1/3. This method is not the same as just replacing components, and the unit is reborn as equipment with higher performance. The Energy Conservation Center focuses on popularizing “Retrofit” from the perspective of energy conservation.

Energy Conservation Center
Managing Director, Doctor of Engineering
Mr. Taniguchi majored in physical metallurgy at the University. By simulating the diffusion behavior of solute atoms in metals using a computer, he clarified the relationship with physical properties. (Graduated in 1981)
He worked with a steel manufacturer after graduation where his responsibility was the development of converters and continuous casting equipment used in the steelmaking process, new product development of high strength steel sheets for automobiles, and design of manufacturing equipment from materials. His next responsibility was research planning at the headquarters division and was a member of the international project for steel-based body weight reduction of vehicles where he studied body structures for the next generation vehicles.
After joining the Energy Conservation Center in 2010, he has been involved in policy planning support, guidance to businesses on energy conservation, and development of energy conservation tools, etc. to date.
＜The Energy Conservation Center＞
A group of experts who contribute to society through a wide range of activities such as diagnostics and advice to factories and buildings on energy conservation, issuing information on energy saving, and support for nurturing energy conservation human resources, etc
