Abstract(s)
The topic of sustainability is of high importance today. Global efforts such as the Montreal
Protocol (1987) and the Kigali Amendment (2016) are examples of joint work by countries to reduce
environmental impacts and improve the level of the ozone layer, the choice of refrigerants and air
conditioning systems, which is essential for this purpose. But what indicators are to be used to
measure something so necessary? In this article, the types of air conditioning and GWP (Global
Warming Potential) levels of equipment in the project phase were discussed, the issue of TEWI
(Total Equivalent Warming Impact) that measures the direct and indirect environmental impacts
of refrigeration equipment and air conditioning and a new methodology for the indicator was
developed, the TEWI DC (DC is the direct application for Data Center), and using the formulas
of this new adapted indicator it was demonstrated that the TEWI DC for Chicago (USA) was
2,784,102,640 kg CO2/10 years and Curitiba (Brazil) is 1,252,409,640 kg CO2/10 years. This difference
in value corresponds to 222.30% higher annual emissions in Chicago than in Curitiba, showing that
it is much more advantageous to install a Data Center in Curitiba than in Chicago in terms of
environmental impact. The TEWI indicator provides a more holistic view, helping to combine energy
and emissions into the same indicator.
