Evaluation of radiant heating floors with the use of renewable energies for the air climate control of houses in the Cañar Province.

The energy efficiency of buildings is based on the reduction of high energy demands, especially in the face of weather variations that require the supply of climate control, contributing to the excessive use of energy. To achieve energy savings, strategies are devised with criteria of almost zero energy buildings, passive or based on sustainable evaluations, where the current regulations or assessment criteria propose better solutions in terms of sustainability in buildings. In context with the above, the energy flexibility of single-family houses is proposed with the adaptation of heating floors as a methodological contribution in the construction area, through renewable energies, in order to optimize energy consumption, reduce carbon emissions, improve comfort and thermal wellbeing. The research shows the characteristics of a system for the placement of climate control heating floors through performance tests, which relate energy savings with the efficiency of the system to mitigate the high energy consumption. These simulations define the behavior of a house in different conditions through the use of BIM technology to represent the best energy efficiency; this, through a relational experimental research, where data were obtained from the energy savings based on the efficiency of the radiant floor system, to identify the optimal system for the placement of climate control heating floors in single-family houses, depending on the areas delimited in the architectural spaces and the materiality of the modeled system, of three specific points of the province of Cañar-Ecuador. With the MIDUVI social housing typology as the basis for the modeling, the spaces maintain their distribution and 7 circuits of the simulated radiant floor systems are formed. Among the parameters that characterize these systems as they produce greater variation in the reduction of resources or energy demand are the layout, the separation and therefore the length of the pipes. These systems are adapted to the use of a reversible heat pump, air - water, whose higher power according to the heating or cooling conditions will be generated by photovoltaic modules located on the roof of the house.
