The environment ethic deals with the research on relation between human beings and the nature. The residential environment ethic is a detail study of environment ethic, which studies the relation between human beings and residential environment. The residential environment ethic presents the human duty to care about and protect residential environment and actually to protect human beings themselves. But the residential environment is facing many dangers, such as city pollution and indoor air pollution, which are closely related to building materials. So, one of the ways for improving the residential environment quality is to use green building materials.  相似文献

Based on the characteristics of spatial structure of residential units, the law of indoor hot smoke flow was investigated by experimental research on a platform model with multiple floors and rooms in a residential building. Three factors exerting influence on hot smoke flow in residential construction were mainly analyzed, including the relationship between the height of space and the area of single room, the size of doorway opening, and the hub space. Based on basic concepts of thermodynamics and fluid mechanics, the geometric relational model of the height of space and the area of single room impacted on filling speed of hot smoke in room was presented by conservation of mass. Moreover, under the influence of hot smoke flow, the formula of doorway opening size was developed by conservation of momentum. The results show that the fire safety of residential building should take full account of the impact of spatial structural. The indoor temperature distribution and hot smoke flow path will be controlled effectively by the design of single room size and room connectivity.  相似文献

Residential area mode of China originates from "neighborhood unit" and "unit compound", they are isolated from the city and known as "islet" and "fragment". The isolation of residence from city breaks the urban structure, increases scale of blocks, and aggravates urban traffic and other problems. In view of this, it is imperative to explore the ways of designing "friendly neighborhood boundary spaces" between residential areas and the city, for example, by extending urban street spaces inward, opening boundary spaces of residential quarters to the city, constructing a boundary space network of residential areas harmoniously integrated into street life.  相似文献

To study the climatic control strategies of the residential building indoor acceptable thermal environment, firstly, based on adaptive model, integrated indoor activities, clothes and spot investigation on air velocity of residential building, this paper calculates an acceptable temperature range. Secondly, through state-space techniques, common passive regulating technologies in residential building have been simulated, including different ventilation rates and divided-period setting ventilation effect on indoor temperature. Meanwhile, monthly regulating methods for ventilation have been proposed. Thirdly, through ventilation technology, effective regulating zone of outdoor climate parameters have been analyzed, which is combined with hythergraph of outdoor temperature, humidity, solar radiation and air velocity. Taking the characteristics of the human thermal comfort adaptability into consideration, the energy-saving potential of the study results is also analyzed.  相似文献

Many residential buildings use externally insulated wall structures in Chongqing, P.R. China. The process of determining the economic insulation thickness was based on degree days and present worth factor when wall structure adopted different insulation materials. The optimal economic insulation thickness was related to the region of the building, air conditioning operating time, and price of insulation material. Insulation materials with better thermal performance have a shorter payback time and wider prospects for application.  相似文献

Based on the characteristics of spatial structure of residential units, the effect of building space construction on temperature raise and hot smoke flow in residential fire was analyzed on building model with simulating multiple floors and rooms. The raise and distribution of temperature indoors were mainly tested under varied location of fire sources. And, the rule of smoke flow was discussed by using the law of temperature raise, indirectly. The results indicate that the mode of smoke flows is influenced by three spatial factors which include the form of junction terminal room construction; the height of down stand above the door and the relative locations of each room. The diffusion of hot smoke is prevented effectively by the down stand of the room; the temperature difference between indoor and outdoor should be higher than that of the room without down stand. When the open direction of door in non fire room is opposite to that of the door in fire room, there is much more hot smoke.  相似文献

MARKAL is a generic model tailored by the input data to represent the evolution over a period of usually 40 to 50 years of a specific energy system at the national, regional, state or province, or community level. The database specifies the energy demands -industrial, commercial, residential, and transportation that need to be satisfied over the next several decades. It describes the available sources of supply of energy, either domestic resources or imports of oil, coal, natural gas, nuclear fuel, and renewable. A menu of technologies is provided for extracting, transporting, converting, and using energy, both existing technologies and those expected to be available within the time horizon of the model. The essential characteristics of the technologies are specified, such as their investment cost, operating and maintenance costs, service life, fuel use, efficiency, availability, output, and maximum expected market penetration. As a linear program, the model then chooses the best combination of these technologies to satisfy the projected energy demands. The basic components in a MARKAL model are specific types of energy or emission control technology. Both the supply and demand sides are integrated, so that one side responds automatically to changes in the other. The model selects that combination of technologies that minimizes total energy system cost. In the end, the article describes energy conservation for building in Chongqing.  相似文献
