This research was carried out with the objective of evaluating environmental and economic impact of solar collectors use in livestock units from the Institute of Animal Science. A simple classification model with factorial arrangement 4x2 (4 months of the year and in two different times) was used in Genetic 4 units, porcine sanitary filter and rearing. Temperature was measured and CO₂ emissions were calculated as well as economic impact was determined from the equivalent tons of oil saved. There was no interaction, neither for genetic 4 nor for swine sanitary filter, but there was for rearing. February and August showed the lowest and the highest temperatures, respectively. The temperatures were higher in the afternoon. There was a saving of 7.17 t equivalent of annual oil, which represents 5814.45 USD. In addition, 19.61 t of CO₂ were no longer emitted into the environment. It is concluded that solar collectors are a very efficient and low cost alternative that helps to reduce costs of livestock production and contributes to the workers’ comfort taking into account savings generated by electricity
