Brazil has average climatic characteristics of a tropical country, with high temperatures and rainy summer. The excessive rains and high temperatures damage plants and create favorable conditions for the emergence of diseases. The greenhouse keeps plants from meteorological agents and allows control of optimal climatic conditions for crop production, enabling cultivation in unfavorable conditions and achieving good productivity during the offseason. The structure and systems are applied to greenhouses and influence directly in temperature and relative humidity of the indoor environment. The behavior of these variables isn't distributed on a homogeneous way and gradients of temperature and relative humidity are found along the height and length of the greenhouse. The lack of information about weather elements behavior in each structure can influence the culture that will be installed, the building project and, hence, the investment required to purchase the structure. The project goal is to characterize different configurations of the greenhouse, from the simplest only with natural ventilation until the most sophisticated with application of systems such as shading, mechanical ventilation and evaporative cooling, with sensors installed at different points of the internal environment, in order to identify the thermal mapping for each configuration and the temperature reduction that each technological level provides. These answers will help on understanding the thermal behavior in the internal environment of greenhouses, essential for the development of construction greenhouses projects and for the appropriate indication of cultivation for each system.
