Studies On Structural System Of Self-insulation Multi-Storey Residential Buildings

Energy efficiency is an important developing strategy in our country and realizingnational energy saving becomes one of the major issues. Because of the differencesbetween counties and cities, the development of energy efficiency has been slowdownin these places of counties. With the advancing of self-insulation buildings, it is possibleto make energy saving popular. Carrying out the Studies on self-insulation buildings,improving the indoor heat environment quality become a significant step to achievenational energy saving.Based on the present of energy efficiency in counties, the paper uses the methodscombined with theoretical calculation, test and numerical simulation to researching theself-insulation buildings which main bearing structure is DS bearing hollow bricksself-insulations. Through systematic research, the major productions gained are:(1) Analysis the distribution of heat flux and gradient of three bricks, DS1brick,DS2brick and KP1brick to use the ANSYS soft. Providing the soft to simulate thethermal parameters in different conditions and comparing with the results by test,improves that the parameters simulated from the ANSYS soft can use for flowedcalculation.(2) Based on the climate of central Shaanxi area, take the DS bearing hollow brickself-insulation wall as main structure of building, analysis the applicability of thisstructural system. Using EnergyPlus software to optimize building envelopes to adaptthe two-way energy efficiency including energy saving and economic saves.(3) Proposing the wall asymmetric design theory. Based on the fourier law, aim tohave same indoor thermal environment of all directions, propose that the outdoor air comprehensive temperature should be taken into account the design of wall structure.Using the methods of theoretical calculation and soft simulation improve the twooptimized purposes.(4) On the basis of different areas, analyze the regional adaptation ofself-insulation wall. In the severe cold region, advising to use self-insulation wallcombined with Inorganic insulation mortar and in cold region can use DS hollow bricksself-insulation wall direct and take advantage of the wall asymmetric design theory tooptimize the self-insulation wall structure.Expect this study make a useful complement for energy efficiency of county’sresidential buildings in severe cold and cold zones and provides theory basis for editingenergy efficiency construction atlas.
