Design Style

To overcome the traditional cave dwelling lacks, we have designed a green cave dwelling area with a safe structure, improved infrastructure, fluent ventilation, good light in northern Shaanxi, which inherited simple ecology in design for traditional cave, integrated modern residential building design style, and increased necessary sanitation. By compared a traditional cave, the results show that the indoor temperature 9°C between the peaks and valleys of Northern Green cave dwelling when the outside temperature difference is 24°C within the test time, and seasonal temperature wave delay time is about 12d. The thermal comfort same as the traditional cave dwellings’.

It is very important to use the daylight in the building design, which is allowed by the windows into the buildings, to reduce the energy consumption. However, on the other hand, the performance of daylight varies according to the floor levels of the building. This research focused on the investigation of the correlation between the performance of daylight and window areas according to floor levels through field measurements and simulation experiments in the residential building. The aim of this research is to derive the adequate window areas according to the floor levels with respect to the orientation of the residential building to achieve the optimum level of daylight and indoor temperature in the livable areas of a residential building. The case selected is residential building from Nagpur region, of Central India. It has a hot and dry climate. The evaluation of daylight level has been done with selected parameters like percentages of Carpet Area to Window Ratio (CAWR) and Orientation by using daylight metrics, namely Useful Daylight Illuminance (UDI) (with Daysim and Radiance analysis tools plug-in Ecotect 2011 software). The findings of this research are the adequate area of window according to floor levels with respect to the orientation in the livable areas of the residential building.

Block Approach

Post-occupancy evaluations (POEs) are useful for evaluating the success of any building design, but are particularly useful in evaluating green buildings. It is the only opportunity architects and engineers have to learn if their buildings actually work as planned. On the other hand, following the “guidebook” of a green building, i.e. having occupants aware of the particularity of the premise and taught about how it works and what the proper usages are (which are not automatically straightforward), is of prime importance since misuse of a green building can directly lead to discomfort and energy over consumption. In that framework, this paper stresses the link between occupants’ usages and their indoor thermal comfort by attempting a quantification of the impact of each usage on indoor temperature and hygrometry (and thus thermal comfort), showing by the way that, in order a POE to fully give exploitable results, a communication to occupants on proper usages has to be the first step after the delivery of a green building. To study that link, the real case of a green building located in the French tropical island of La Re´union has been used. The overall idea followed in this work lies in two steps: The first one is the creation of a “validated” digital building description obtained thanks to a process of comparison between simulations outputs (DesignBuilder) and field measurements (weather and comfort stations), and to a “block by block” approach that allows independent validations of the description of the fabrics and of the description of the usages. The second step is the utilization of the model obtained in the first step to perform simulations of new usages, as modifications in natural ventilation features (doors, windows open or closed) or in number of occupants, lighting schedule etc. These new simulations lead to the possibilities of comparing situations between each others, and therefore of quantifying the contribution, positive or negative, of each chosen usage to thermal comfort. Eventually, this paper will describe an example of combination of new usages that makes the conditions noticeably more comfortable within the building, stressing that following the good usages in a green building is a first requirement before realizing any POE.

With the rapid development of the city today, follow the same pattern of the contemporary Chinese residential building design style has become a universal phenomenon. The development of modern residential building national form is one of the important tasks of the designers, the traditional Chinese "harmony" idea has always told people to respect for nature, respect for tradition. Analysis and extraction of Chinese elements in the design of modern residential building, in detail, color, style, has a good reference for the development of national traditional.

In this study, electroencephalogram (EEG) and cardiac activity status of the human body while using various types of seats during rest were analyzed in indoor summer conditions. Thermal comfort was also evaluated through a subjective survey. The EEG, cardiac activity status, and subjective survey during rest indicated that the use of ventilation and cold water-cooling seats was effective. This effectiveness was because of the θ-wave and α-wave activation, sensorimotor rhythm, β-wave reduction, and left hemisphere activation, demonstrating that the conditions applied were suitable for rest. According to the analysis of the subjective questionnaire survey, the use of ventilation and cold water-cooling seats provided a more pleasant state than the basic seat, improving the subject’s warmth and comfort, and also the concentration. In addition, the use of a cold water-cooling seat provided the highest satisfaction level, being the most favorable condition for rest.

There are six basic control items, land saving, energy saving, water saving, material saving, indoor environment and operation, among which, only material saving are related to structure design. We followed the green building design concept and the control items list in those standards during structure design of one of the residential area in Sino-Singapore Tianjin Eco-city, which consist of 15~18-story residential building connected to a large underground garage, as is shown below.
