1、The Technology of Applying Renewable Energy in the New Countryside Ecotype HousesAbstract: Due to lack of scientific design and appropriate technology guidance, countryside houses in our country are universally in poor thermal environment, lag behind in energy production and application, and obvious on energy waste, while the energy consumption on countryside houses is increasing. We should on one hand advocate energy saving, and on the other hand search for renewable energy like solar energy, g

2、eothermal energy, wind energy and biologic energy. This article gives analysis on applying solar energy and biogas energy technologies and puts forward some economical and appropriate technological measures about renewable energy application as technology support and theory guidance for constructing new countryside ecotype houses.Key words: New countryside construction; ecotype houses; solar energy; biogas energy1 IntroductionAs the continuous development of countryside economy, it has been coun

3、try peoples urgent necessary to improve houses functions and living environment, and constructing economical and beautiful green energy-saving houses. The fact is due to lacking of scientific design and appropriate technology guidance, the countryside houses in our country have been in irregular and disorder state for a long time, and the most-seen is the traditional extensive model. In recently year, theres an obvious trend of increasing energy consumption in new countryside houses construction

4、. It has become an unavoidable strategic topic for new countryside construction to construct a safe, healthy and comfortable countryside houses environment while no obvious energy consumption noted.Tsinghua University Construction Energy Saving Research Center used to launch a big and comprehensive investigation and research on countryside construction, energy and environment. The result shows that the countryside peoples income is increasing continuously and theyre able to purchase certain comm

5、ercial energy on one hand, while on the other hand the energy consumption of countryside houses is increasing constantly. As the faster development of countryside economy, ecotype new countryside construction has caught more peoples attention.Energy has been important material basis for human existence and development. To deal with the possible energy and resource shortage problem, we should actively advocate energy saving and search for renewable energies like solar energy, geothermal energy, w

6、ind energy and biologic energy. This article gives analysis on applying solar energy and biogas energy technologies and puts forward some economical and appropriate technological measures about renewable energy application as technology support and theory guidance for constructing new countryside ecotype houses.2 Solar energy application technologySolar energy is a kind of inexhaustible renewable energy, substantial and renewable. Most parts of our country are rich in solar energy, and it has go

7、od exploitation conditions and great utility value. The application of solar energy on construction include space heating, lowering temperature, water heating and so on, which can be divided to two categories of active and passive.Active solar houses are force circulation solar energy collection systems that consist of solar heat collector, radiator, pipeline, blower or pump, and heat storage equipments. The active solar houses require high investment, complicated technologies, frequent maintena

8、nce and certain regular energy consumption. However, passive solar houses dont need or only a little motive power, equipment, or equipment maintenance. The passive solar houses take use of the solar energy for space heating and energy saving. They have good economic, social and environmental benefits. As a result, its more appropriate to use passive solar houses for countryside houses. 2.1 The structure design of solar housesTo make use of solar energy from flat design angle, we can apply a mode

9、l of extra sunlight rooms or sunlight corridors in the countryside houses. The sunlight rooms are south-oriented, and we can use south-oriented corridors, sealed-up corridors, vestibule, etc. The south side should be transparent glass walls, the roof be strength-enough(for human safety) slope glass to maximize the heat storage capacity. The extra sunlight room should be floored with high coefficient of thermal storage materials like cobbles, to collect more heat. Meanwhile double-layer glass should be applied to minimize the heat loss at nights, roller blinds also applicable. At the same time, there should be a 1m2 air outlet for every 2030m2 glass wall of the sunlight room to guarantee good ventilation and prevent the room from getting too hot in summer.2.2 Analysis on sunlight rooms energy efficiency benefitsGraph 1 is one countryside house with extra sunlight room. On December 2010, we tested the temperatures of the sunlight room, ordina
