To identify studies that have applied the concept of reusing computational equipment. This concept has been used for the construction of high-performance architectures aimed at teaching subjects that need environments of this field. Discussions on sustainability have become common in the last few decades and they have also reached the Information Technology such as Green IT. Moreover, into this discussion, one of the main keys is the reuse and disposal of equipment sustainably. Systematic Literature Mapping In this regard, the developed protocol was applied on a national basis focused on education. It has obtained feedback from only 2 studies that pointed to the construction of clusters with legacy computers applied to the teaching. Systematic Literature Mapping One of the main keys is the reuse and disposal of equipment sustainably.
