Evaluation of Thermal Comfort in Traditional Houses in a Tropical Climate

A considerable amount of energy is being consumed for heating and cooling indoor environments in order to provide thermal comfort. For older buildings located in the southern parts of Iran, particularly in Bushehr, many climatic and passive design strategies are being used to provide indoor thermal comfort. This architecture and these elements have been developed in response to unfavorable weather conditions. The current study aimed to identify those passive elements and evaluate indoor thermal comfort in older houses. To achieve these objectives, passive elements in main houses located in the ancient urban structure were first identified. Then, a house in the coastal belt, Tabib’s house, and another house inside the ancient urban structure, Nozari’s house, were selected for the purpose of field measurement. The results revealed that the passive techniques used in these older houses significantly provide sufficient indoor thermal conditions. The mean measured predicted mean vote (PMV) of Tabib’s rooms was 0.88 and the mean measured PMV of Nozari’s rooms was 0.91, which were in an acceptable range. The measured predicted percentage of dissatisfied of rooms in both houses were lower than 10%. The main factor in creating indoor thermal comfort in these houses was the natural ventilation and its availability in the selected houses.

“…The results obtained by the simulations are compared with previous works that focused on the thermal performance of certain methods [62,[76][77][78]. It is worth mentioning that some passive methods have not been thermally analyzed; thus, there is no data available.…”

“…In all cases, the error can be considered as acceptable. Furthermore, since References [62,[76][77][78] are carried out under climate conditions within groups C and D of the Köppen-Geiger classification, and, along with the reviewed passive methods of References , it is considered that the methods are working under similar conditions; hence, the results can be stated as valid.…”

Passive cooling and heating methods within buildings are studied a lot nowadays. Nevertheless, their performance considering their driving has not been deeply studied. Therefore, the performance of the most common passive heating and cooling methods is analyzed in this document. The methods are divided into three categories: operable, semi-operable, and not operable. They are studied under different conditions of operation in order to estimate their performance in terms of indoor temperature increase/decrease in a single dwelling. The study is carried out with the thermal simulation program EnergyPlus, using a dwelling in Mexico City as a case study, which is validated with literature that studied passive methods for similar climates. Furthermore, for an integrated driving, four features of operation of the passive methods are considered: mobility, maintenance, assembly, and consumables. The results show that a correct use of these features of driving might achieve a significant temperature drop in the case of cooling and a significant indoor temperature increase in the case of heating. This is reflected in a considerable amount of energy saving compared to a conventional heating/cooling heat-pump system running under regular conditions, which is taken as a reference of consumption. Thereby, it is concluded that the proper usage, considered here as the correct application of the four features of operation mainly by the occupants, might have a high influence in their performance of increase/decrease of the indoor temperature. Thus, it is highly recommended to follow up their performance once installed and not to suppose an optimal performance ever after.

“…Urbanisation, exponential urban population growth, advancement in technology and quest for modern lifestyle have induced rapid increase in the number of residential buildings of different kind and size without regard to the principles of bioclimatic architecture and sustainability. The plethora of many sophisticated but ineffective and dysfunctional building stocks has caused an excessive increase in energy consumption due to daily anthropogenic activities, as well as new infrastructure require increased energy use for function properly [14]. This has negated one of the main concerns in sustainability which is consideration to climatic conditions, and has added to the already existing global environmental problems.…”

The prevalence of modern residential buildings without adequate consideration of changes in user's needs and preferences in urban centres of South-eastern Nigeria is becoming more worrisome. This study therefore, evaluated the level of knowledge and implementation of bioclimatic principles/practices in modern residential buildings by building design and construction professionals. It assessed the adequacy of bioclimatic elements and occupant level of satisfaction based on selected environmental performance criteria. It employed survey approach and analysed the survey data using mean score index, correlation coefficient and t-test statistics. The result showed a low level of implementation of bioclimatic principles/practices in spite of high level of knowledge about bioclimatic principles/practices by the building professionals. It also found that bioclimatic elements/features in modern residential buildings were inadequate and thus, high level of occupants' dissatisfaction with environmental performance of the buildings. The study further found that adequacy of bioclimatic elements was significantly and positively correlated with the level of implementation of bioclimatic principles/practices and occupants' level of satisfaction. However, a moderate and insignificant positive relationship was found between the level of knowledge and implementation of bioclimatic principles/practices. This therefore, suggested a need for building professionals to transform their knowledge of bioclimatic principles into practice for an improved performance. This would create a balance between traditional values and modernisation and a more comfortable home for living. The study then advocated for a revisit to existing building design and construction laws, policies and codes, and/or institutionalising new regulations that would accommodate bioclimatic peculiarities of South-eastern Nigeria.
