Study On Energy System Optimum Design Of Straw Brick Residence With Fire Pit

Protecting ecology environment assures human sustainable development. Human activity leads to resource exhaustion and global climate warming and desertification, which threat human sustainable development. From the 80s last century, human realized that human activity destroyed environment, and proposed green material concept. All over the world makes measure to control environment deterioration. Green building is a important measure. Green building is the building that saves resource, protects environment, and controls pollution. Green building makes healthy, applicable, efficient using space. "Green building material" industrial institute defines that "green building material" is a good quality and the coordination of using performance and environment building material.The main feature of the energy system of straw brick house with fire pit is the combination of fire pit and straw brick house.. The straw brick house solves heating problem in winter in the east north area for farmer. The fuel of fire pit includes plant straw and detritus. The detritus is a best material, such as wood detritus, rice husk, cattle or horse stool, flax detritus, tree leaf, grass, wheat detritus, plant root and stem, and all kinds of green husk. Burning in the fire pit products heating, and increases temperature of the house through heating conducing, radiating, and flowing. The material of straw brick is straw, including cellulose, half cellulose, lignin, crude protein, and inorganic salt. Straw brick house has ecological advantage for its construction and feature. Straw is inexhaustible renewable resource. The production of straw brick house is no pollution, no harmful matter. After it is demolition, the main material of straw brick house can be degraded.Research method of the paper was the combination of theory and practice, and designed a straw brick house and a common red brick house in theory. Straw brick house heated through fire pit, and common brick house heated through burning coal. The paper calculated and compared the heating load of straw brick house and common brick house, tested temperature indoor and outdoor of the two houses, and compared engineering cost, operation cost, and social benefit at last. The innovative point of the paper is the combination of fire pit and straw brick house, forms a new energy system, and compares the house with new energy system and common house.
