Indoor environment conditions affect the wellness, health, productivity, happiness, and performance of the building's occupants. Physical activity spaces require specialized comfort parameters related to performed activity outcomes to achieve a comfortable sports process. In attempting to achieve an optimal interior comfort level for the average person, current building management systems use predetermined guidelines that depend on physical and physiological aspects. Floor vibrations, an indirect measurement that was intended, were recorded as acceleration values from the activity area utilizing smartphone-embedded sensors during synchronized group physical activities. The activity level periods are intended to be objectively estimated depending on the acceleration that was captured. The thesis approach is making general inferences about performing activity intensity within the space desired to capture depending on human-induced floor vibrations. Heart rate monitoring is used to detect the actual physical intensity as a validation for the acceleration-based approach to a rough activity intensity estimation. To evaluate the relationship between floor vibrations and the degree of physical activity, two time series data have been analysed using wavelet-based analysis techniques. The synchronization of building management and automation systems and space-based real-time collected occupant data may be the solution to generate comfortable interior physical activity environments. A foundation for efficiently monitoring intelligent building systems is offered by activity intensity estimation of the collective motion data that has been captured from performing space.
