Urban areas with dense buildings generate significant artificial heat, contributing to the heat island phenomenon. In recent years, the expansion of data centers, which operate ICT equipment 24/7, has raised concerns about increased heat emissions from servers.

Therefore, we are seeking startups with new ideas and technologies for utilizing unused heat, as well as data center operators willing to cooperate in demonstrations, to implement collaborative (demonstration, PoC) projects.

1. Purpose of this Project

The purpose of this project is to enhance the reliability of technologies and products that contribute to the effective utilization of unused heat by matching startups possessing new ideas and technologies for utilizing unused heat, such as data center waste heat, with data center operators who have the actual sites, and by promoting collaborative (demonstration, PoC) initiatives, thereby leading to social implementation.

2. Implementation Structure of this Project

(1) Startups

Will be responsible for technology provision, demonstration execution, and results reporting as the main body of the demonstration.

(2) Data Center Operators

Will cooperate in demonstrations, such as providing demonstration fields.

*Implementing Organization (Deloitte Tohmatsu LLC)

Will be responsible for the formation and operation of collaborative projects, supportive assistance, and public relations.
