“…It is generally agreed that our climates are changing and that the average temperature will rise gradually. In response to this, there have been a number of researches on the impact of climate change on energy consumption and carbon emissions of office buildings in China [5][6][7], Sweden [8], Greece [9], and Australia [10].…”

A CO2 emission in construction materialization stage is the key research point of architectural life cycle assessment, which is concentrated in emission time and in absolute emission volume. To build a calculation model for CO2 emissions in the materialization stage of office buildings, it should take into consideration the CO2 emissions generated from production and transportation of construction materials and equipment as well as the CO2 emissions generated from the construction process. By this calculation model, the CO2 emissions are analyzed and calculated of 78 office buildings in construction materialization stage. On average, the CO2 emissions in construction materialization stage are 326.75 kg-CO2/m 2 ; with the increase of building height, CO2 emissions per unit area increase significantly and the CO2 emissions per unit area of super-high-rise buildings are 1.5 times that of the multi-storey buildings; the CO2 emissions of Civil Engineering account for 75% of the whole construction materialization stage; And the carbon emissions of steel, concrete, mortar and wall materials reach over 80% of the Civil Engineering. The storeys of the building and the consumption of construction materials are taken as two independent variables to set up a prediction model for CO2 emissions of office buildings in materialization stage. By statistical analysis and comparison, it can be found that the prediction formula using steel reinforcement, concrete and wall materials as independent variables can better predicate CO2 emissions in the construction materialization stage.

“…That was probably the main problem to be solved, since winter could be solved, if necessary, by means of hearths. As Danny H. W. Li [85] asserted, when the temperatures began to rise, as happened 18,000 years ago, when agriculture was established, the greatest problem to be faced was the summer, and the dwellings must adapt to it. Consequently, the energy demand rises in the arid regions during these periods.…”

“…As was demonstrated, the use of light colors in hot areas, such as the ones used in the pueblos, and dark colors in cold regions, such as the envelope of the earthlodge, reduce the energy consumption of the dwellings [86]. The main solution proposed in the aforementioned research [85] for this problem consists of increasing the adaptability of the dwellings built in these regions. This idea could be reinforced by analyzing the tipis, built in one of the hottest areas of North America, the Great Plains.…”

The Sedentary Process and the Evolution of Energy Consumption in Eight Native American Dwellings: Analyzing Sustainability in Traditional Architecture

According to the research developed by André Leroi-Gourhan in 1964, entitled “Gesture and speech”, the evolution of human beings during Prehistory was linked to the search for work efficiency. As time passed, man designed increasingly complex tools whose production implied a decreasing amount of energy. The aim of the present research was to determine if this evolution, which occurred in parallel to the sedentary process, also affected architecture, specifically if it can be detected on traditional dwellings, particularly in those built by the Native American Indians during the pre-Columbian period. Due to their great diversity, since both nomad and sedentary models can be found among them, and to the available information about their morphology and technical characteristics, these models offer a unique opportunity to study the consequences of this process for architecture. In order to achieve it, an alternative parameter that can be determined for any type of building was designed. It allows us to establish the amount of energy an envelope is equal to. The results obtained suggest that the efficiency of the dwellings decreased as this process went forward, but this pattern changed in its last step, when agriculture appeared and permanent settlements started to be built. Besides, statistical graphs were used in order to show graphically the relationship between it, the climate, the morphology of the dwellings and their technical characteristics.

“…Recent extreme weather events and global trends in climate change have made researchers take into account the negative effects arising from urbanization. Therefore, creative communities should be implemented with approaches that promote energy conservation and carbon reduction to achieve [ 37 , 38 , 39 ]. This implies increasing the efficiency of an urban community throughout the life cycle, substituting or reducing carbon-based energy, technological innovation and behavioral changes.…”

With globalization, the notion of “creative city” has become a core concept of many cities in the world development policies, with real properties being upgraded or used to change, renewal is being conducted, and creative industries are emerging. This trend has reached its peak in the past decade, with different forms and scales gathering global development momentum among the creative communities to promote the development of creative economies. In recent years, however, there was still skepticism about the sustainability of the current creative communities. Many scholars have pointed out that signs of unsustainability have begun to appear in many creative communities. To overcome these obstacles, the development of rational and highly effective improvement strategy requires a dynamic thinking process. Therefore, this study employs the DEMATEL-based ANP with modified VIKOR (D-DANP-mV) model in presenting an assessment framework for the sustainability of creative communities. This system is used to assess the sustainability of current creative communities and determine how to solve their problems. Thus, continuous and systemic improvement strategies can be developed to achieve the aim of sustainable development. Two creative communities in Taiwan, Taichung Cultural and Creative Industries Park (TCCIP), and Shen-Ji New Village (SJNV), are used as case studies in this study. Based on the concept of systematic improvement from fundamental issues, the results indicate that the improvement priorities can be determined by applying the D-DANP-mV model. This approach is different from those found by a conventional method with the hypothesis of independent criteria (e.g., diversification of creative talents in TCCIP), and cannot use for performance improvement (e.g., only can be used for ranking and selection among alternatives). Considering these points, unreasonable premises, biased errors, and lack of some real application functions in the process of resource allocation could be more efficient improvement strategies generated in this proposed model.
