The objective assessment measured the different factors affecting the thermal comfort inside the case study houses by using a data logger and handheld equipment. The subjective assessment aimed to measure the response of the occupants by using semi-structured interviews and self-directed questioners. The results will be a further stepping-stone in motivating people to find value in their heritage and to preserve, reuse and reinhabit their houses while also stressing the importance to pass traditional knowledge to younger generations. The results showed a better performance for the vernacular houses while showed significant importance of adopting the passive strategies even with the new concrete houses.

A study on the thermal behavior of traditional residential buildings: Rasoulian house case study

Journal of Building Engineering, 2016

Traditional buildings throughout the globe provide instructive examples of sustainable solutions to building design problems. In recent years, researchers and architects have conducted different studies that represent the principles of Iran's climate-responsive architecture. Yazd traditional buildings are examples of Iranian architecture that bear characteristics of environmentally friendly buildings. Thermal performance and comfort condition of these buildings in summer have been the matter of interest in recent studies. In this article, summer sections of Yazd traditional homes and their thermal behavior were studied. Yazd is located in hot and arid regions of Iran. EnergyPlus software program was used to investigate the thermal behavior of this house. To validate the developed model, a field study was carried out with lascar electronics data logger. The results reveal that internal temperature of summer sections in all seasons has less fluctuation than the outdoor temperature. Also, weather temperature in underground spaces is closer to the comfort temperature in comparison with spaces near to the ground floor. Therefore, to provide thermal comfort condition in these homes the least amount of non-renewable energy is needed.

A Comparison Study Between the Thermal Performance of the Original and Rebuilt Vernacular Buildings of Dana Village in Jordan

The Journal of Engineering Research [TJER], 2022

The settlement of Dana in Jordan is undergoing dramatic and rapid changes. The rehabilitation project launched by the Royal Society for the Conservation of Nature (RSCN) provided new tourist accommodation within the settlement, in a way that preserves its unique vernacular character. This has involved the repair and transformation of existing dwellings as well as the rebuilding of those that have been demolished. Currently, the original and rebuilt buildings stand side by side, offering a unique opportunity to compare their thermal performance. This comparison is essential to understand the impact of new construction materials and opening sizes on the thermal performance of vernacular buildings. For this purpose, the thermal performance of rebuilt and original buildings was monitored in August 2019 and February 2020, representing the hot and cold seasons. The recorded data was interpreted statistically, aiming mainly to compare the results from the original rooms with those from the...

Thermal Comfort and Building Design Strategies for Low Energy Houses in Libya Lessons from the vernacular architecture

Since the last century a growing movement of individuals and organizations that seek the redefinition of how buildings are designed, built and operated to be more responsible to the environment. The critical contribution of the residential building in this matter emphasizes the need to study the houses thermal performance and its impact on environment, considering the human thermal comfort requirements. The reduction of the energy demand for heating and cooling is the key factor in the low energy houses and minimizing environmental damage caused by the emissions of carbon dioxide.

The Thermal Performance of Vernacular Houses as An Identity of Kurdish Traditional Architecture Article history

Nature in general and especially climate, play a decisive role in defining the architecture of a place or people over time. Therefore, it is more convenient to look at architecture as a mirror reflects people's adaptation and behavior to the environment over time. Because of mainstream design with low-tech conditions, the climate is the predominant power that characterizes the building types. In this manner, as long as the climate differs from one place to another, the vernacular architecture is going to be differs as well, due to the environmental conditions. Traditional houses were adopted to meet the basic psychological and physiological needs of man through the most rational elements, such as building floor plans (spatial organization), materials, shapes, details and floor effects in various ranges. As a result, these architectural features marked the identity features of local architecture in the city. For this reason, the paper focuses on testing the thermal performance of some types of vernacular houses commonly used in the city of Sulaimani, especially in the traditional zone of the city. To achieve the research objectives, the study followed experimental analytical methodology, using outputs of the most appropriate software (Design Builder) to test the performance of three common types of local traditional houses (single and double floors). It appears that the type L with single floor is the most efficient, but the U shape with single floor recorded the highest number of days throughout the year when energy was needed.

Thermal comfort, adaptability and sustainability of vernacular single family houses in Libya

Tehnicki vjesnik - Technical Gazette, 2017

Preliminary communication Traditional and vernacular housing was developed in close relation between the functional needs of the occupants, the culture, climate, and other aspects of the living and built environment. Over the course of the last decades, most developing countries, including Libya, have experienced a rapid economic growth and increase in population, leading to the increase in construction of contemporary single family houses influenced by western models. The paper analyses aspects of thermal comfort in traditional single family houses in mountain (city of Gharyan) and desert regions (old city of Ghadames) in Libya with an aim to investigate advantages of the vernacular concepts in contemporary design. The study will establish valorisation criteria by researching structures, materials, internal arrangement, roof, openings and other aspects that influence sustainability. The results will be used in the fields of architecture, urban design and building industry in Libya, since the knowledge of traditional concepts and elements sustained through a long period of time will be valuable in building healthy homes and saving non-renewable energy in contemporary structures.

Passive Techniques for Achieving Thermal Comfort in the Vernacular Dwellings of Bikaner

International Journal on Emerging Technologies 8, 2017

Vernacular architecture based on bioclimatic concepts was developed and used through the centuries by many civilizations across the world. Different civilizations have produced their own architectural styles based on the local conditions. Bikaner is a non basin settlement in the hot and dry climatic region of India. The vernacular architecture of the Bikaner haveli's has provided a comfortable shelter against the harsh climatic conditions of the region. However, it has not been studied in the quantitative evaluation method. This study is carried out on the vernacular buildings of bikaner, India. A survey of residential haveli's, more than 100 years old was carried out in the walled town of Bikaner. The objective of the investigation was to understand the passive environmental control systems of vernacular architecture of Bikaner to achieve thermal comfort. The results show that the natural and passive design systems provide comfortable indoor environment irrespective of the outdoor climatic conditions.

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 effect of building plan form on thermal comfort in the traditional residential patterns of the hot and dry climate of Qom

Heritage Science

Buildings should be constructed such that their energy efficiency is high in different climatic conditions while providing acceptable thermal comfort at the same time. Climatic and architectural incompatibilities will increase energy consumption to provide thermal comfort but have adverse effects, both economically and environmentally. Climatic design is the best and most effective way to maximize the use of renewable energy sources. Traditional Iranian houses have always exhibited this type of architecture and can provide suitable examples for design for contemporary architects. This study aimed to investigate the effect of building plan forms on the thermal comfort temperature in residential buildings with the help of traditional architectural patterns. The method of this research is descriptive-analytical and has been conducted through case studies and simulation tests. Data collection has been undertaken through literature review and field observations. The houses in this study ...
