Saltillo Coahuila, due to the lack of an adequate architectural design, some homes do not meet the thermal environment conditions required during the winter period, it is estimated that 471,725 habitants are affected by temperatures until - 3.4°C, which causes morbidity problems, so that the need for the use of electromechanical air conditioning systems with electrical energy consumption of high economic and environmental cost arises. The objective of the work was to study the feasibility of applying a geothermal heat exchanger for home heating. Periodic variation of soil temperature at different depths was studied to determine the optimum by experimentally validated equations. An ideal depth of 3 m was determined due to a variation of 25 y 30% and lower excavation cost compared to depths of 6, 9 and 12 m.
Pandemics have always generated a change in all fields, in the social, cultural, habits, customs and even in the spaces, at the end of 2019 (COVID19) is declared a global pandemic by the World Health Organization.

The objective of the work is to determine what changes have been generated regarding social distance in interior spaces and shopping habits in the Saltillo metropolitan area. The methodology is of a mixed approach, longitudinally; using a virtual survey and the traditional and virtual ethnography method to document its phases in 2020 and early 2021, as well as a bibliographic review of theories on social distancing. The results show that the biggest problem is inside the houses and that there is an increase and decrease in mobility in purchases and use of public spaces, faced with this contingency the answer is different, due to the culture and customs of each place. So, there is a lot to work on this topic.
