For the term “white space”, the SDIA accepts the definition provided by Eduard Oró and Jaume Salom in their book and research article published by the Catalonia Institute for Energy Research (IREC), Spain.

Eduard Oró and Jaume Salom (2017) defines white space as follows:

IT room or data hall. The IT room is an environmentally controlled space that houses equipment and cabling directly related to compute and telecommunication systems which generate a considerable amount of heat in a small area. Moreover, the IT equipment is highly sensitive to temperature and humidity fluctuations, so a Data Centre must keep restricted power and cooling conditions for assuring the integrity and functionality of its hosted equipment. Thus, many manufactures call the IT room as whitespace.
