Simulation system and evaluation method used for housing unit

The invention provides a simulation system used for a housing unit and a method for evaluating the housing unit by adopting the simulation system. The simulation system comprises a building containment assembly, a function usage assembly and an assisted positioning grid. The evaluation method comprises the following steps: setting a coordinate grid on the ground, and selecting origin of coordinates; according to a product to be simulated, selecting the required building containment assembly, and positioning the building containment assembly by combining the ground coordinate grid; setting and placing the function usage assembly; and detecting and evaluating the housing unit. By adopting the housing unit simulation system provided by the invention, a real indoor space is rapidly and flexibly simulated, visual experience of a designed living room is provided for a designer or a user, and humanity care is reflected. Meanwhile, usage of space of each living room can be simulated, a problem can be found, and the assemblies are moved, thus the housing unit is more simplified, land is saved, and functional requirement of daily living can be met.
