Soil is build up by water, air and solid, it contains much water and has many small pores inside.
The host designed it by himself or somebody of his friends whose professional knowledge was defective, and the workers didn’t construct the building in accordance with the norm.
We suggest removing the buildings whose level is D, and steady the level C; Fourthly, to change the state of unordered situation, we want the government proposes technical support during the process of building, and improve the professional level and quality of the construction works.

It also designs to create and construct focusing on water, vegetation, and environment, introduce the natural ecological elements into the middle of people's lives.
Implementation of recycling of waste within the community, such as stone and other waste can be reprocessed to form stone veneer, stone floors and other water seepage Classified waste treatment within the community: recyclable and not recyclable, and put them into the recycling center according to the nature of the nearest garbage.
Co-ordination planning of water environment in community.
Establishing the water recovery system in the community then treated to a certain standard for the residents.
green space per capita public green area of 40 square meters and 80% of the plants for native species in the region Multi-level green, ground water seepage Social control Encourage residents to participate in the planning process and implementation to move back Public participation in low-carbon community building, self-government Conclusion In the city of community level, explore "low carbon" design strategy and content planning, and explore "low carbon" community development model from the perspective of planning and design professionals and it must be built on the basis of a wide range of social identity, also needs coordination and effort of government, the public, developers, indigenous people and other aspects to get good results.

Partially or totally derived from biomass, the absence of guarantees to users in terms of durability of these materials lead to a misunderstanding of such materials by the public and a mistrust by the building sector professionals.
In fact to reach that, several experimental and numerical studies was done to highlight the hygroscopic behavior and the thermal transfer in materials [14]–[16], In the majority of the numerical studies, Künzel model was used due to its capacity to stimulate the coupling transfer of heat and water [17], [18].
Hygrothermal behavior of a multilayer wall The numerical modelling used in this paper is based on a macroscopic description of thermal and water transfers with the help of the coupled equations of Künzel model [13].
The equations governing water and heat transfer in this simulation are based on the following transport equations [13]: (1) (2) where: ∂H∂T –heat storage capacity of moist building material, ∂w∂ϕ -moisture storage capacity of the building material, λ –thermal conductivity of the moist building material, Dw –liquid conduction coefficient of the building material, δ – water vapour permeability of building material, hv –evaporation enthalpy of the water, T –temperature, ϕ –relative humidity, t –time.
From these equations of conservation of mass and energy, we can obtain a much simplified equations: (3) (4) where: μ –is water vapour diffusion coefficient, u –is materials water content and ρw –is density of water The Table 1 shows the basic input data required by WUFI.

Mathematical Model Both water and air are assumed to be incompressible and isothermal Newtonian fluids.

Water supply and drainage facilities.
In Changchun half of the villages have no running water, the villagers using their own courtyard wells.
Most of the villagers believe that water quality is well, but well water can easily be contaminated and its quality is not guaranteed.
Environmental pollution is serious: some villages affected by the urban industrial, soil, air, water, etc.
So, we should strengthen construction workers’ legal consciousness and professional quality, uniform plan the construction of rural residential, enhance the management to improve the quality of rural housing.

Based on three main stages which includes planning and design, construction, operation and management there is a six technical indicators system, they are: land saving and outdoor environment, energy saving and energy use, water saving and water resources use, materials saving and materials resources use, quality of indoor environment and operation and management.
The general framework of green construction includes six aspects which are construction management, environmental protection, materials saving and materials resource use, water saving and water use, energy conservation and energy use, land saving and land protection in construction.
Traditional concrete curing method which sprays and keeps water on concrete surface is still the major curing method, a considerable amount of drinkable water flows away or evaporates in vain.
Water tap, lamp, power switch and doors etc. usually are changed in re-decoration because of the quality and brand problems.

Contract governance (regulating provisions through the life of the contract) These seemingly simple tasks involve an array of professionals working together and contributing different skills.
This is because, even after successfully contracting with the private sector, failure to recognise and take into cognisance the many stakeholders has led to protests which turned violent in some cases resulting in the failures of water projects in Buenos Aires (Argentina), Cochabamba (Bolivia); buy-back of the Skye toll Bridge (UK).
While it may be surprising that both sector that have different goals and objectives within the framework of the partnership do not differ regarding the desired skills, it should be noted that professional perspectives often remain the same irrespective of sector affiliations. 5.
