1、Green Building General State 1. The background of green building: Present society the theory of sustainable development have permeated every aspect of human social development, how to can promote the economic development of human society to again solve the problem of environmental protection have al
2、so become people broad is the problem of solicitude one. sustainable development ask the development of society economy must restrict in the environment and resource of the earth can bear ability in. well-known, in recent years mankind in economy develop fast at the same time, bring environmental re
3、source consume rapidly and atmosphere 2 C0 plenty of increases, so make atmospheric temperature go up , cause global climate to warm , the damage of ozonosphere, the damage of as well as natural landscape and so on. nowadays mention extensively green building system only put forward according to thi
4、s problem.Forestation construction is that the opinion that uses ecology ( Ecological thinking) come to working space and the life of creation people.So, create to come out, healthy and comfortable space, not only, do not increase investment , can have energy-saving function actually more and reduce
5、 operation cost, and the production efficiency of improvement space user. 2. the environmental problem of green building It can offer the comfortable indoor environment that has safety , should at the same time have if so-called green building is not only wanted with natural environment the good bui
6、lding external environment of harmonious appearance. Green building consider local climate, building form and use square work , facility condition , construct process, housing materials and use manage the influence for external environment, as well as comfortable, healthy internal environment, at th
7、e same time consider investment person and user , design , install , run , the interests of maintenance technician, change speech may lasting design and good environment and is benefited should have balance between 3 user , well move mutual concern reach the forestation effect . of optimization Gree
8、n building is only that the energy of difference and the demand of difference between the coordinative internal and external environment and user and balance of starting point is relied on with this viewpoint level reaches the nature of building and environment , is melted with. 2. 1 The indoor envi
9、ronment of green buildings Green building emphasize indoor environment , because the thought of main stream of air-condition circle is want to strive for a relation of balance in between external environment, for internal environment for health , comfortable and building user produce efficiency, sho
10、w the demand of difference. Temperature problem First hot comfortable obvious influence work efficiency. the air-condition system of tradition can maintain indoor temperature, however, in last few years study show , indoor reach absolute comfortable, cause easily air-condition disease problem, consu
11、me plenty of energies just, increase freon for the damage of ozonosphere。 Green building is asked besides guarantor body overall hot balance, should notice body individual position, if head and enough department are been good at for the special requirement of temperature, apply natural energy, . oth
12、er, now adopt frequently maximum glass surface construct may occur greenhouse effect in summer, occur in winter from the radiation effect of low temperature of cold glass surface. design condition therefore except winter summer air-condition besides, will analysis local climate and building internal
13、 load change for the influence of indoor environmental comfortableness. best every month each hour of change for air-condition load and the influence of comfortableness. On 2.1.2th in illumination tomorrow, sound problem( Daylighting and Voice Problem)Different indoor luminous environment directly a
14、ffects working efficiency and indoor atmosphere . introduce free from contamination in green building, smooth colour good sunlight is the part of green luminous environment as light source. but the luminous environment of comfortable health should at the same time include is easy watch , safe beauti
15、ful luminance distribution, dazzle control and intensity of illumination even control etc., should regulate strong light according to place and the time of difference therefore so do not affect sunlight of high quality. other, healthy comfortable sound environment is helpful for the health of human
16、body of body and mind. green sound environmental requirement do not harm hearing and reduce noise source as far as possible. , will usually produce the equipment of noise design arrange alone in is far away from use room position, control outdoor noise level. Air quality( Air Quality) Air quality good have reflected badly satisfy people ask for environment level. usually affect
