## 2 Materials and Methods
* Window Wall-Solar Gallery Ratio (WWSGR): proportion of windows in the original facade between the glazed terrace and the rest of the dwelling. * Window Frame Ratio (Fr): \"glass curtain\" frame size ratio. * ggl,SG: solar factor of the \"glass curtain\" glass. * ggl,SG: solar radiation control of the \"glass curtain\" glass. * Solar Gallery-Indoor Dwelling Ventilation Ratio through the wall (SGIVR): ventilation rate between the glazed terrace and the inside of the dwelling through louvres or glazing openings. * Thermal Balancing Ventilation Ratio (TBVR): supply ventilation flow rate of the proposed heat-balancing fan system. \begin{table}

The influence of whether the glazed terrace is thermally insulated on the floor, roof and side walls, or whether the terraces of adjacent dwellings are glazed, was also studied. DesignBuilder software (version v.7.0.1.006, DesignBuilder Software Limited, Stroud, UK) was used for the computer simulations. This software uses the EnergyPlus calculation engine, which is specific for the simulation of the thermal performance of buildings [56]. This software allows us to calculate the evolution of daily temperatures, thermal comfort and energy demands throughout the year. This program also allows us to calculate and visualise the distribution of temperatures and thermal comfort in the different areas of the dwelling by means of computational fluid dynamics (CFD). The thermal envelope construction characteristics obtained from the on-site measurements were considered in the computer calculations. The virtual model also considered the geometrical characteristics of the dwelling, the walls between the interior rooms and their orientation. The floor slabs and partition walls with neighbours were considered thermally adiabatic because the dwelling is surrounded by other dwellings occupied all year round as it is a residential building, not a holiday building. This calculation method, in accordance with current standards, considered the thermal transmittance transmission of solar radiation through semi-transparent surfaces with the correcting coefficients of the solar factor, the air permeability and the absorptivity of the frames [58] (Table 2). The computer simulations considered occupation, HVAC efficiency, usage schedules, setpoint temperatures, ventilation air renewals and thermal gains of lamps (Table 3). The use of summer solar shading is proposed with the following features (Table 4).
