This paper describes a method to calculate "natural exergies" associated with solar radiation, effective radiation, evaporation of water and underground warm and cool storage. We first examined the variable types of so-called natural energy, which is a technical term widely used in the field of building environmental science, and then showed that they can be defined by the concept of exergy. We call this "natural exergy". The values of any natural exergies are positive. For example, stored exergy under the ground as a quantity of state is positive without exception. We calculated the annual amounts of natural exergies in Tokyo, and we tabulated the results as a chart that can be used to evaluate the regional climatic situation from the view point of exergy.
