Methodology in research on photovoltaic cogeneration integrated in building

There are currently various universities and institutions developing research into the integration of photovoltaic systems in buildings, internationally known by its abbreviation in English, BIPV (Building Integrated Photovoltaics). Within this technology, one aspect stands out, considered innovative, the integration of hybrid models or cogeneration. This technology, which we shall call BIPVT (Building Integrated Photovoltaics Thermal), integrates a hybrid module in the building, which not only generates electricity, but also uses residual energy that is lost in the form of heat or light, to increase the energy efficiency of the building, in applications with low temperature. However, the methods to test the efficiency of this investigation and evaluate its cost benefit, are not clear, and constitute a challenge for the investigation within an architectural framework.
