## 2 Materials and Methods
The indoor temperatures were recorded via on-site measurements to analyse the thermal behaviour of the dwelling throughout the day and throughout the year. The dry-bulb air temperatures were measured using a hot-wire sensor (Figure 4a). The mean radiant temperatures and mean operating temperatures were measured using a black globe probe (Figure 4b) and with thermocouples. A humidity/temperature sensor with a wireless handle was used to measure the outdoor air temperature, relative humidity, and indoor air velocity. On-site measurements of the indoor temperatures were taken in the most used areas of the dwelling: in the centre of the conservatory, on the living room sofa, on the dining room table, in the kitchen workspace, in the centre of the hallway, in the centre of the bathroom and on each bed. On-site measurements of the outdoor temperature were performed in the street, 10 m away from the building. The outdoor and indoor measurements were taken simultaneously. Several indoor measurements were taken at a maximum time interval of 1 h to ensure the same outdoor weather conditions and the same outdoor temperature. Figure 2: Building of the dwelling under study: (**a**) general view of the building and (**b**) interior distribution of the analysed dwelling. A typical dwelling in the building was analysed. User surveys on thermal comfort were also carried out to check users' perceptions. The surveys were completed by the 4 occupants of this dwelling. The current daily electricity consumption of the dwelling was measured. The dwelling has a single-zone electric air-conditioning system. The surveys were carried out at the same time as the measurements. The dry-bulb air temperatures, mean radiant temperatures and mean operating temperatures were analysed and their distribution in the dwelling space was studied. Humidity and outside temperatures were also measured. The measuring instruments were to be switched on five minutes before taking the measurements to enable the sensors to adapt to the indoor temperature. The HVAC system had to be switched off all day so as not to artificially change the temperatures in the dwelling. This is why the on-site measures were performed on particular days and why automatic data loggers could not be used. The on-site measurements and surveys were carried out simultaneously, between 13:30 h and 14:30 h, fortnightly, for one year to cover all the climatic conditions of the year. Thermographic photographs were taken with a Testo 868 camera (Testo SE & Co., Ltd., KGaA, Titisee, Germany). The thermal transmittance, dry-bulb temperature, average radiant temperature and humidity were measured using a Testo 435-2 multifunctional

Part 3. Computer simulations were used to evaluate the thermal effect of the modification of various geometrical and constructive parameters of the glazed terrace analysed. Before calculating the new proposals, the computer simulations were adjusted and validated by comparing the virtual results with the on-site measurements. The analytical results of the PMV and PPD were also checked against the surveys, and the computer-calculated annual energy needs were checked against the current consumption. Once the validity of the informatics calculations had been tested, several design parameters of the glazed terrace were changed to determine the effect of each parameter on the thermal performance of the dwelling. The design parameters considered were as follows:
