    For elaboration of this investigation, at first stage, components in machine room of the entity were identified. These elements are classified according to their sector: in generation, distribution and heat utilization equipment. Based on this, technical information about equipment installed in the place was collected. System losses were estimated according to the most recent period (December 2021 - March 2022), allowing to know anomalies that interfere in the operation of the environment in relation to numerical and quantifiable data. Similarly, financial costs were established about losses, reaching a value close to ten thousand dollars. The efficiency of the steam generator was evaluated at 84.67 percent (useful heat), distribution at 83.75 percent (harnessed heat) and heat exchanger at 42.43 percent. Improvement proposals were suggested that involve equipment cleaning based on maintenance periods, replacement of insulating materials and application of coating on specific surfaces, with the aim of raising the performance of the environment. Thus, the efficiency of the steam system would increase to 84.79 percent (harnessed heat) based on the recalculation with the suggested improvements. In addition, an annual saving of three thousand dollars was determined with a discount rate of 12 percent, with which the associated investment would be recovered in two years.
