The main objective of this research was to evaluate the spatial distribution of the
thermal variables, acoustics and lighting in climate controlled compost dairy barn. The
experiment was conducted in October 2017, in a farm located in the west of Minas Gerais state,
Brazil. For the study, the interior of the animal facility was divided into 120 meshes equidistant
points, in which air temperature (tdb), relative humidity (RH), noise, illuminance, and air speed
(Vair) were manually collected. The technique of geostatistics was used to evaluate the distribution
and spatial dependence of variables. Spatial distribution maps showed the occurrence of high
variability of attributes and content within the animal facility. Thermal environment variables
showed alert situations throughout practically the entire facility. The noise and luminance levels
were within the recommended values.
