Currently, the crisis in several sectors that the global scenario is inserted is one of the reasons for the need of sustainable development. One of these crises is related to the management of water resources. Problems related to the scarcity of this resource and situations of water stress are faced, and there is a greater concern about the future. Thus, there is a real need for alternatives that rationalize water use. An alternative is the use of water generated by the operation of air conditioning devices, which usually drips in the exterior area of the buildings or is directed to network of rainwater or sewage, not having a rational use. This work was developed with the aim of quantifying the volume of water generated by the 88 air-conditioners at the Technology Center of the UFRN, central campus, located in the city of Natal/RN, and to verify if it is possible to meet the demand for cleaning and irrigation for this building. The survey of monthly demand for cleaning and irrigation resulted in 4,260 and 26,143.2 liters respectively. After 24 measurements of the flow of air-conditioners, with cooling capacities ranging from 7,000 to 48,000 BTU, and considering the operating time of 6 hours daily, a monthly volume of 12,210 liters was found. This corresponds to 286.62% of cleaning demand, 46.70% of irrigation and 40.16% of both irrigation and cleaning, representing a significant saving of water, which should not be neglected. In sum, condensed water from the air through the operation of air-conditioners is an alternative to mitigate the damages caused by the uncontrolled use of water resources.
