For buildings with low heat demand for heating, energy balance is based on the difference between two similarly large numbers (heat gain and heat loss) and the calculation becomes more sensitive to changes in parameters. Output hourly simulation method is the temperature in "free-floating" mode, which the unlike the needs for heating provide better information on the thermal behavior of the building itself and to model dynamic response of the object to certain changes in the input data. For the purpose of the evaluation is determined by the minimum and maximum acceptable temperature and the area within the boundaries called comfort zone. In this paper a low energy house is evaluated in terms of energy performance and thermal comfort, where some parameters are changed in order to determine sensitivity. The methodology is based on a sensitivity analysis (SA) and MonteCarlo simulation based on a stochastic random selection. Thermal comfort is evaluated with adaptive thermal comfort.
