Abstract (EN): A new simplified method for calculating the monthly solar heating fraction of direct gain buildings is presented. Two different operating regimes have been considered: (1) thermostatically controlled temperature, typical of buildings with auxiliary heating systems; and (2) free-floating temperature, typical of buildings without auxiliary heating systems. In the latter case. to quantify the thermal behaviour of the building, a comfort solar fraction is introduced. In this method, the solar fraction is a function of three parameters: (1) the solar/load ratio; (2) the building thermal inertia; and (3) the monthly non-utilizability. Some examples of the application of the new method are presented, as well as comparisons with the results from existing methods.
