Canada is implementing the recycle plan of housing materials, have developed the recycle equipment of dry wall, paperboard, timber, plastics and pitch. The health of the healthy person of person is concerned with indoor air quality and the quantity of water quality as well as such as light, noise and the radiation etc. background factor of electromagnetic field. Indoor air quality design healthy building should be plied with below principle : Reduce contaminant。( 2) distinguish whole room illumination and special illumination( as desk lamp)。 environmental responsibility。 energy efficiency。 meet way of life and the change of needs。 high limit land reduce building waste material and family waste material。 proper construction method etc..3 The intension of healthy buildingFor 10 few years, western economic developed country builds material and healthy building for health, have given fairly big attention, have gotten some progresses preliminarily, . they have worked out some organic volatile matters( VOC) give off the test method of quantity, have stipulated some health build the performance standard of material, carry out low distribution quantity sign certification beginning from some materials, with promote health build the development of material. in advocate and develop health build the foundation of material on, some countries have established residence and official business use the healthy building of sample plate, have gotten high appraisement and warm wele.Healthy building is established not using high new technology building, is to use , existing establish for environment and healthy beneficial material , for city, suburb and rural each and every unit is expected and may realize , it offer a cleaning to people fortable indoor environment, also with nature, munity and entire environment appearance coordination.Healthy building should be considered : use energy and resource efficiently。 manage with easy operation machine and system, repair easily and update 。 use durable housing materials and equipment product。Green Building General State1. 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 also bee 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. wellknown, in recent years mankind in economy develop fast at the same time, bring environmental resource 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 this problem. Forestation construction is that the opinion that uses ecology ( Ecological thinking) e to working space and the life of creation people. So, create to e out, healthy and fortable space, not only, do not increase investment , can have energysaving function actually more and reduce operation cost, and the production efficiency of improvement space user.2. the environmental problem of green building It can offer the fortable indoor environment that has safety , should at the same time have if socalled green building is not only wanted with natural environment the good building 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 fortable, healthy internal environment, at the 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 Green 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 environment of green buildingsGreen building emphasize indoor environment , because the thought of main stream of aircondition circle is want to strive for a relation of balance in between external environment, for internal environment for health , fortable and building user produce efficiency, show the demand of difference.Temperature problem First hot fortable obvious influence work efficiency. the aircondition system of tradition can maintain indoor temperature, however, in last few years study show , indoor reach absolute fortable, cause easily aircondition disease problem, consume 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, . other, 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 aircondition besides, will analysis local climate and building internal load change for the influence of indoor environmental fortableness. best every month each hour of change
