“…Moreover, wall construction systems affect indoor environmental conditions and comfort levels: a single layer of a homogeneous material performs very differently in this respect from multiple layers of different materials with different thicknesses and thermohydraulic properties [13,[15][16][17][18].…”

The structure of historic buildings and the materials used in their construction, along with outdoor conditions , affect indoor temperature and humidity. The walls of San Juan Bautista Church at Talamanca de Jarama, Madrid, Spain, exhibit differences in water absorption, whose explanation is to be found in the various types of construction involved in its over seven centuries of building history, the weather conditions and the walls orientation. The south wall fluctuations in inner temperature and humidity produce 11-16 h thermal lag and a very low decrement factor ensuring comfortable interiors all year round with minimal fluctuations in temperature.

ResumenLa calificación ambiental térmica es el procedimiento mediante el cual se evalúan las consecuencias de la implantación, ampliación, modificación o traslado de las actividades y elementos al interior de la vivienda estudio de caso, para comprobar y determinar las medidas correctoras o precautorias necesarias para prevenir o compensar sus posibles efectos térmicos sobre los espacios. Donde se argumentará que la climatología urbana y el sistema constructivo establecen el ambiente higrotérmico. Se observa y monitorea los valores térmicos y su oscilación, de consigna fijada para invierno y verano. Con base en los resultados se determina el comportamiento anual de temperatura y humedad relativa medio mensual así como las estrategias de adaptabilidad y la clasificación higrotérmica. El trabajo metodológicamente es una investigación experimental aplicada, donde los diferentes métodos se apoyan en varios tipos como el documental, de campo y descriptivo. El objetivo de la presente investigación es determinar la calificación ambiental térmica únicamente de temperatura y humedad relativa, al interior de la vivienda común en Tampico, México. Palabras clave: Adaptabilidad climática; características constructivas; zona constanteRecepción: 30-06-2015 Aceptación: 23-11-2015 Fuentes Pérez, C. AbstractThermal environmental rating is the process by which the consequences of the implementation, expansion, modification or removal of activities and elements within the housing case study, to try and determine the corrective or precautionary measures necessary to prevent or evaluated compensate possible thermal effects on the spaces. Where it will argue that urban climatology and establish constructive system hygrothermal environment. It observes and monitors the thermal and values your swing, setpoint set for winter and summer.Based on the results of the annual performance average monthly temperature and relative humidity as well as strategies of adaptability and hygrothermal rating is determined. The experimental work is methodologically applied research, where different methods rely on various types as the documentary field and descriptive. The objective of this research is to determine the thermal environmental qualification only temperature and relative humidity inside the common housing in Tampico, Mexico.

“…Passive strategies search to mitigate the heat transfer between the thermal zones and the environment, using new materials and alloys for construction or retrofitting in order to give buildings a better resistance against the environmental conditions [3]. However, these solutions are still in development and its deployment is subject to the economic cost, durability, climatic factors, and facilities of installation.…”

“…In India, the isolation given by a thermal paint on the facade and rooftop of a building provided reductions of 4.4 °C [11]. Similarly, in Shanghai, the reflectance of the walls after applying thermal paints increase from 32% until 61% [3].…”

Original scientific paper https://doi.org/10.2298/TSCI190525077M Smart control systems and new technologies are necessary to reduce the energy consumption in buildings while achieving thermal comfort. In this work, we monitor the thermal evolution inside a scale reduced closed space whose exterior and/ or interior wall faces have been painted with a coating solution. Based on the experimental data obtained under different environmental conditions, a simulator was developed and tuned to reproduce the thermodynamic behavior inside the spaces, with a relative error of less than 3.5%. This simulator lets us also estimate energy savings, temperature, and flux behavior under other conditions.
