Figure 5: Collection of thermal sensation responses in field study Based on this methodological procedure, 45 groups and 98: observations were obtained.

Table 3: Thermal comfort ranges (reduced and extended) estimated for cold period of Ensenada city. three warm thermal sensations (slightly warm, warm and hot). Color intensity indicates the approximation of the TS levels to the extremes thermal sensations: cold and hot. Figure 8: Thermal ranges by thermal sensation level for the cold period of Ensenada city. In this sense, from a temperature below 16.8 °C people begin to perceive cold, which is intensified for every 1.7 K that reduces the temperature; likewise, from 23.8 °C people begin to perceive warmth, which is intensified every 1.6 K that increases the ambient temperature Figure 8 shows a graph of the results contained in the previous table. The Tn and its thermal comfort ranges can be identified, as well as thermal amplitudes from which the evaluated people would feel each thermal level considered in the subjective scale. Blue bars refer to the three cold thermal sensations (cold, cool and slightly cool), the purple bar is of thermal comfort (neutral) and the red bars are the Table 4: Thermal comfort ranges (reduced and extended) estimated for cold period of Ensenada city. (Figure 8). This gives a local model of thermal comfort corresponding to the cold period in Ensenada, and from which can be derived different patterns of human performance, construction systems, architectural design, building materials, etc. However, it is also possible to observe that 3 % of people showec slightly warm, 4 % of people perceived slightly cool and 4 % of people felt cool (Table 4). This shows that 12 % of the population sample was evaluated in thermal conditions outside the thermal range statistically accepted by people. This means that with the extendec range, statistically the response of 95.5 % of the study subjects is included (Figure 7), but that during the evaluation, the indoor space: in which 88 % of the sample was evaluated was found in therma comfort conditions (Figure 9, Table 4).
