Indoor thermal environment monitoring has been done in 20 residential buildings of Liege city followed by questionnaire based comfort survey amongst the occupants of 85 houses in order to record their preference and expectations about indoor thermal environment in winter and spring season. It is found from the analysis that change of glazing has a minimum or even sometimes an adverse effect on the existing indoor environment due to the absence of proper insulation of the rest of the building envelope. It is observed that in winter there is a sudden drop in indoor temperature and also overheating in summer. This is due to unplanned installation of glazing which actually increases the fenestration area ratio leading to higher indoor temperature fluctuation and causes discomfort. It is also important that the occupant?s preference and expectations as well as overall assessment of indoor environment needs to be consider towards energy efficiency improvement.

An optimal design is taken on the external respiration double skin facade (DSF) of a office building in Wuhan. The indoor thermal environment of the office units in the building have been simulated by taken computational fluid dynamics (CFD) method, and then the paper analyzes the indoor temperature changes under the condition that the internal airflow status of the DSF for natural ventilation, without shade, vents closed and other cases, discusses the influences of different inner glazed skin’s thermal properties, DSF for active ventilation and different wind speed on indoor thermal environment, according to the simulation results we obtain parameters of relevant optimal design.

This paper reviewed related research works and developments on the traditional architectural element “mashrabiya” focusing on its history, design and structure, typology, and functions in hot climates. Moreover, the paper assessed the effect of the traditional mashrabiya on the indoor thermal environment and thermal comfort in a selected case study building. For this purpose, two similar rooms were investigated in a selected historic building with abundant mashrabiyas located in the Makkah Region, specifically in Old Jeddah, Saudi Arabia. The field tests were conducted during a typical hot summer month with two different configurations. The study demonstrated that opening the mashrabiya allowed more airflow into the room during the day and reduced the indoor temperature by up to 2.4 °C as compared to the closed mashrabiya. Besides, the building envelope played an important role in preventing the high fluctuation of the indoor air temperature, where the fluctuation of the rooms air temperature ranged between 2.1 °C and 4.2 °C compared to the outdoor temperature which recorded a fluctuation between 9.4 °C and 16 °C. The data presented here can be used for the future development of the mashrabiya concept and the potential incorporation with passive cooling methods to improve its design according to the requirements of modern buildings in hot climates. Moreover, further studies and tests on mashrabiyas under different climatic conditions are required. Also, the different strategies or materials can be incorporated with mashrabiyas in order to improve its thermal performance.

The purpose of this study was to investigate the effects of building microclimate on the indoor thermal environment of traditional Japanese houses, focusing especially on the shading effect of trees as well as the cooling effect of spraying water. Basically, the indoor thermal environment was found to follow the outdoor conditions due to the open-plan and lightweight wooden structure. Nevertheless, air temperatures of the living rooms in the two case study houses were lower than the corresponding outdoors by approximately 0.5 °C and 2 °C, respectively. It was found that the semi-outdoor spaces acted as thermal buffers for promoting cross-ventilation as well as pre-cooling to provide “warm but breezy” conditions to the surrounding indoor spaces. The results showed that the surface temperature of semi-outdoor spaces can be reduced by shading and water spraying, among which shading has prolonged effects and water spraying can reduce the surface temperature during peak hours and the following night.

In order to master the indoor thermal environment of the traditional dwelling houses in dry hot and dry cold climate zones in winter, the east Gansu province is taken for example to study. Indoor and outdoor air temperature, relative humidity, solar radiation intensity and wind speed were obtained by using field-tested methods for the traditional dwelling houses in this region in winter, and the clothing form and activity of people were surveyed by way of questionnaire. And then, the influence of house orientation, indoor heat sources and insulation on the indoor thermal environment is analyzed, the WCI (wind chill index) is used to evaluate the indoor and outdoor thermal environment at last. The results show that: the indoor temperature can raise about 8.3 °C when the house orientation is better and Chinese kang as the heating heat source. The good practice on local structure is worthy of following for other houses, such as adobe posted solid brick wall, double windows, wooden sash windows and so on. However, people still feel very cool or cold about the indoor temperature for much of the day, and even people feel very cold for 5% of the day. At the end of thesis, some methods about the indoor thermal environment improvement are proposed.
