Thermal Performance Analysis Of Biologic Materials Used As Building Thermal Insulation Materials

At present, energy and environment have become major global concernedproblems. With the energy consumption, the existing fossil energy reserves will beexhausted, so the development of new energy is imminent. In this paper, through thecombination of investigation, experiment and simulation methods, the thermalperformance of biologic as building six common biologic materials was researchedand analyzed. The main contents of this paper include:(1)119households were investigated，The concrete contents include structureof rural building，present utilization situation of biomass resources，the obstacles ofdeveloping biomass utilization technology，and so on.(2) From the calorific value experiments of the common biologic materials likelily stalks, sawdust, rice straw, rice husks, peanut shells, corn stalks and others in ruralareas. The results show that: the common biologic materials in rural areas have goodcombustion performance, and the standard coal coefficient is between0.380and0.537.(3) Do thermal conductivities experiment with six common biologic materials in ruralareas of natural accumulation by the guarded hot plate method. The experimentalresults show that the thermal conductivities of six common biologic materials isbetween0.0504W/(m K) and0.0790W/(m K), and the common biologicmaterials is comparative analyzed.(4)Based on the data of biomass production and building energy consumption byChina Statistical Yearbook statistics, the biomass production reaches1.34283billiontons and the building energy consumption reaches816million tce. However, biomassutilization is only21%of total energy consumption. With the improvement of livingstandards and the change of lifestyle, most of the biomass resources are lie aside and wasted.(5) The biologic materials as building insulation layer components of ceiling,floor, wall and roof were introduced. With the experiment data through the simulationsoftware, the thermal performance of biologic used as composite wall was simulatedand analyzed. And the waste biologic used for building energy conservation materialsto the efficiency of emissions reduction and energy saving were analyzed...
