The aim of the study was to make an ecological assessment of the seasonal dynamics of the microclimate in a for building 200 cows. Temperature, Relative humidity, Wind velocity, Level of cooling, ammonia, carbon dioxide and hydrogen sulfide in the building environment were studied for a whole calendar year. The animals were fed all year round being tied in a building built of steel-concrete elements. The ecological assessment was that an optimum temperature relative humidity regime of the air in the building was not ensured in the winter and in part of the summer and the other intermediate seasons. The magnitude of the cooling was higher than the optimum one in the winter season and lower in the summer season. The values determined of gas content and of wind velocity speed were within the ecological norms all year round.
