Passive solutions in the concept of energy efficiency play an important role in reducing energy consumption, and emissions of CO2. However, controlling the parameters of walls, and roof thermal Inertia is the perfect way to ensure comfort inside houses. In this paper, an investigation of thermal inertia behavior, and energy efficiency of clay with natural, and industrial additives: cork, wool, and waste of plastic. The use of those materials will improve the comfort of the inhabitants of the cold area who suffer from the hard climatic conditions, not just the block’s clay will be extracted from the same area but also they will be sun backed, the thing which will reduce the huge energy consumption of brickyard. A study of the energy efficiency of those materials was done using TRNSYS, and an evaluation of their environmental impact was evaluated by calculating their emissions in terms of CO2. The results obtained indicate an important characteristic in term of thermal Inertia, for a value of thermal transmittance of U= 0.55 W.m-2.K-1, we need 0.9m thickness of wall using the heavy concrete, however, if we use clay, we gain 69 %, clay-plastic we gain 79 %, clay cork, we gain 87 %, and by clay-wool, we earn 89 % in term of the wall’s thickness. For the delay of the heat flow of a wall of 25 cm, we could assure a delay of above 11h instead of just 2h for the heavy concrete. Concerning the heating need during a year during the cold season, the clay presents a need for 1500 KJ.h-1. Concerning the footprint carbon, the composite clay-cork has a negative footprint carbon; however, the clay and clay-wool present a low carbon emission near zero when the clay-plastic and the heavy concrete present the highest value of emissions.

The purpose of the paper is to research and analysis energy-efficient technology suited the residential building and energy consumption level of building, master the application of energy saving technology in building, thus provide the basis for energy saving and integrated application of adaptability in different buildings. The basic materials of residence in Shenyang were collected by the form of survey analysis, at the same time, evaluation and analysis of the energy consumption data. Through the investigation and building self assessment index analysis of the heat consumption, to achieve the requirements of the energy saving 65%.Building is obviously relevant to climate, and 90% of electricity consumption for appliances and lighting. There is a lot of energy waste with 40% of the building water consumption for flushing. Through to the analysis of the residential energy consumption, the key to energy saving of residential building are the thermal performance of the building itself, make full use of natural light and other measures, and improve the energy consumption of the system in the building and equipment efficiency.

This paper focuses on the operation principles of the double-skin facade (DSF) in winter of severe cold area. The paper discussed the main influence factors of building energy consumption, including the heat storage cavity spacing, the air circulation mode, the building envelope, and the building orientation. First, we studied the relationship among the thermal storage cavity spacing, the temperature distribution in the cavity of the DSF, and the indoor temperature. Then, we discussed the influence on the ambient temperature in the building exerted by the air circulation system of the double-skin facade. Finally, we analyzed the influence on the whole building energy consumption of the DSF buildings under the situation of different building envelopes and different building orientations. Based on the results of the numerical simulation, the paper put forward an operation strategy analysis of the DSF buildings in severe cold area, in order to achieve the purpose of building energy saving.

Objective To explore the relationship between window opening ratio and natural lighting and energy consumption of University Gymnasiums in severe cold area, and put forward optimization strategies. Methods Digital simulation technology was used to simulate the energy consumption and natural lighting of University Gymnasium window opening ratio, and the window opening scheme with natural lighting and low energy consumption was obtained. Conclusion The side window lighting should be used in the window opening scheme of small and medium-sized university gymnasiums. Within the range of experimental data, the North-South lighting is the main lighting mode, and the East-West lighting is the auxiliary.

Rural residential energy consumption accounts for 46.6% of total building-related energy consumption of China. In Northeast China, energy consumption for space heating represents a significant proportion of total rural residential energy consumption and has reached 100 million tce (tons of standard coal equivalent), or more than 60% of total household energy consumption. In terms of energy consumption per square meter of gross floor area, rural residential energy consumption for heating is more than that of cities (20kgce/m2). However, the average indoor temperature of most rural residence is below 10°C, much less than that in cities (18°C). Hence, it is an important task for Chinese energy saving and emission reduction to reduce rural residential energy consumption, while enhancing indoor thermal comfort at the same time. Restricted by local technology and low economic level, rural residences currently have poor thermal insulation resulting in severe heat loss. This paper reports on research aimed at developing design strategies for improving thermal insulation properties of rural residences with appropriate technology. A field survey was conducted in six counties in severe cold areas of Northeast China, addressing the aspects of indoor and outdoor temperature, humidity, internal and external surface temperature of building envelop enclosure, and so on. The survey data show the following: 1. Modern (after 2000) brick-cement rural residences perform much better than the traditional adobe clay houses and Tatou houses (a regional type of rural residence in Northeast China – see figure A) in overall thermal performance and indoor thermal comfort; 2. Among the traditional residential house types, adobe clay houses have better heat stability and thermal storage capacity than Tatou houses; 3. Applying an internal or external thermal insulation layer can greatly improve rural residential thermal insulation properties, and is an economical and efficient solution in rural areas; 4. In terms of roofing materials, tiled roofs show much better thermal insulation properties than thatch roofs; 5. Adopting passive solar techniques can form a transition space (greenhouse) against frigid temperatures, resulting in interior temperatures 5.91°C higher than the outside surroundings. It is evident that local passive solar room design offers significant heat preservation effects and lower cost ($12/m2), embodies the ecological wisdom of rural residents, and is therefore important to popularize. The above experimental results can provide guidance in energy conservation design for both self-built residences and rural residences designed by architects. In addition, the results can also provide experimental data for energy-saving studies for rural residences in China.

In order to improve the heat transfer in enclosure structure of passive houses in cold area with complex climatic conditions, a three-dimensional model is established to investigate the time-by-case changes of outdoor temperature and solar irradiation based on the principle of integral change and the method of response coefficient and harmonious wave reaction. The variations of hourly cooling and heating loads with outdoor temperature and solar irradiation are analyzed. As simulated by cloud computing technology, the passive building energy consumption meets the requirements of passive building specifications. In the present research, super-thermal insulation external wall, enclosure structure of energy-conserving doors and windows, and high efficiency heat recovery system are employed to achieve a constant temperature without active mechanical heating and cooling, which suggests a strategic routine to remarkably decrease the total energy consumption and annual operation cost of passive building.
