Differential thermal analysis (DTA) is complementary to thermogravimetric analysis (TGA). However, DTA is much more versatile. The data obtained from DTA are of more fundamental in nature. In DTA, a smaple and a reference material are heated (or cooled) at a linear heating rate. The difference in temperature between the substance and the reference material is recorded against either time or temperature as the two specimens are subjected to identical heating rate. Using this technique, qualitative identification of a compound can be done by determination of the temperature at which endothermic or exothermic reaction takes place.

Indoor Thermal Comfort Analysis: A Case Study of Modern and Traditional Buildings in Hot-Arid Climatic Region of Ethiopia

Profile image of Yared Girma

Urban Science

Indoor thermal comfort is an essential aspect of sustainable architecture and it is critical in maintaining a safe indoor environment. Expectations, acceptability, and preferences of traditional and modern buildings are different in terms of thermal comfort. This study, therefore, attempts to evaluate the indoor thermal comforts of modern and traditional buildings and identify the contributing factors that impede or facilitate indoor thermal comfort in Semera city, Ethiopia. This study employed subjective and objective measurements. The subjective measurement is based on the ASHRAE seven-point thermal sensation scale. An adaptive comfort model was employed according to the ASHRAE standard to evaluate indoor thermal comfort. The results revealed that with regards to thermal sensational votes between −1 and +1, 88% of the respondents are satisfied with the indoor environment in traditional houses, while in modern houses this figure is 22%. Likewise, 83% of occupants in traditional hou...

Indoor thermal comfort is essential for occupants' well-being, productivity and efficiency. The hot-dry climate with its extremely high temperatures and intense solar radiation is becoming hotter and drier in this era of climate change and global warming. Thus providing for indoor thermal comfort and reducing energy use in buildings is becoming increasingly difficult. This has called for new ways of thinking and re-evaluation of the existing methods of tackling this problem. This research is based on a field survey comfort study conducted in Bauchi, in northern Nigeria during the dry and rainy seasons in 2009. Thermal comfort index is evaluated and compared with human responses. Findings indicate the need to review the fundamentals of the requirements for thermal comfort and adaptation by the occupants. Finally the paper concludes that findings should be presented in a format that would be useful and appropriate for architects to design climate sensitive residential buildings

Sustainability

Achieving optimal levels of indoor thermal comfort in a warm, humid climate continues to pose a challenge to building occupants in such climatic regions. Buildings are either being retrofitted or designed differently to cater to thermal comfort. As a result, a variety of tactics have been deployed to guarantee optimal thermal comfort for occupants. Some scholars have highlighted the salient contributions of various types of construction materials toward the delivery of different housing types which perform differently under a diverse range of climatic conditions. A plethora of studies suggesting better indoor thermal comfort performance of traditional buildings as compared to contemporary dwellings due to various reasons have been observed. However, limited studies have sought to investigate this suggestion within warm, humid climatic regions. As such, this study engages in an evaluation of indoor thermal comfort qualities of traditional and modern buildings during the dry season wi...

The indoor thermal conditions in residential buildings in two locations in Abuja, Nigeria were investigated to understand the ideal conditions of occupants in this hot-humid climate. Understanding these conditions helps give an insight into what people are experiencing in their houses and how they adapt to the high temperatures. The study seeks to fill the gap in research of occupants’ thermal comfort in this area by providing empirical thermal comfort data from a city in the tropical region. During the study, 86 households responded to a post occupancy questionnaire to evaluate their building and how they adapt to high temperatures. A comfort survey questionnaire was administered to occupants of four low-income residential households to assess their perception of their thermal environment. These included two air-conditioned and two naturally ventilated buildings with the questionnaires having over 80% return rate. Simultaneously, physical measurements were taken in the living room,...

The study examined the perception of occupants on thermal comfort in Jimeta, Nigeria where the temperature is high, hot and dry weather. The objectives are to assess factors impacting on indoor thermal comfort, and effect of ventilation on heath of occupants in the area. Indoor thermal comfort and room temperature survey of thirty occupants' living rooms were taken using thermometers. Results show that building forms and orientation, building openings to floor area ratio, landscaping, and building fenestration have direct effect on the average room temperature of residential buildings. Challenges of high temperature, insomnia, fatigue, boredom, headache, poor arousal, and asthma are among health implications of inadequate ventilation suffered by occupants. It is recommended that building professionals be engaged in planning, design and construction of buildings to aid the application of building orientation, ratio of building openings to floor area, and landscaping among others to achieve ventilation and comfortable temperature.

A field study was conducted to understand the real and preferred conditions of thermal comfort in low-income residential buildings in Abuja, Nigeria. Knowing the temperatures people are experiencing in their houses and the limits which residents can tolerate is a first step to proffer passive solutions to reduce discomfort. During the study, 40 people responded to a post occupancy questionnaire and two households were issued a comfort survey questionnaire. Physical measurements were taken simultaneously during the comfort survey in both an air-conditioned and naturally ventilated residential building. The ASHRAE and air flow sensation scale were chosen as voting scales. The results from this study show that during the monitoring period the average and maximum temperatures in an air conditioned residential building were 31°C and 34°C; and 33°C and 36°C for natural ventilated buildings in Abuja. This compares with the external average and maximum air temperatures of 31°C and 39°C.

Human thermal discomfort is a serious problem in Nigeria where the temperature and humidity stress is always high. Occupants of residential homes therefore resort to the use of active cooling system. This paper empirically examined the thermal comfort of traditional residential buildings in Nigeria using Igbo traditional residential buildings as a case study. Such buildings were identified to be mainly in rectangular and circular in typology with little or no windows. The roof is thatched. Experimental research method was used in this study to obtain data on environmental and human parameters. Subjective measurement was used to collect information on thermal sensation and thermal preference of the occupants of the Igbo traditional residential buildings. The results showed that the average thermal sensation experienced by the occupants of the buildings vary from cool to slight warm. Ventilation was not much felt in the indoors. The study recommends for high-level window openings to g...
