Then, a questionnaire survey was designed; and with the help of various stakeholders, consists of green building certified professionals to support the process in choosing the determinant factors.
Introduction In the 21st century, most cities in a country strive for the best possible to provide services such as healthcare, education, housing, public safety and security, water and waste management to increase people’s well-being.
Methodology This study employs a quantitative approach by distributing questionnaires to the sample population consisting of Green Building Certified Professional and from Green Building Certified Professional Bodies from the Association Malaysia (REHDA), Malaysia Green Building Index.
Besides, the sample population is also distributed to the government department, Ministry of Energy, Green Technology and Water, and Public Work Department Malaysia.

GIS in Education and Professional Practice in Romania GIS has been developed in the United States in the 1960’s as land management software.
Other professionals like civil and transport engineers, urban planners, economists or even journalists do not have the opportunity to learn in universities about today’s available land and traffic management technologies, even though they may use these technologies to create a support for certain professional decisions.
These numbers may represent a base for park renewal interventions or for testing the efficiency of new pedestrian routs like railway underpasses or bridges over the Bega water channel.
Data on the left of Fig. 1 represents grouped parks in areas with low housing (like the ones along the Bega water channel), while data on the right of the chart represents individual parks in the center of dense neighborhoods.

Urban residents, who experience the urban style, should be invited to co-design with the professionals.
Then professionals should be organized to select the information to inspire innovation.

Therefore, the utilization rate of global energy can be improved greatly if the professional heating systems could be equipped in civil buildings where people live.
Only the professional quality, practice skills, and design standards of design personnel can be improved in an all-round way, a scientific and practical heating design plan can be ensured for civil buildings.
The commonly used heating technologies can be concluded as follows: (1) co-generation of heat and power, which is a comprehensive energy utilization technology using the low-grade heat energy for heating after using the high-grade heat energy of fuel to generate power; (2) concentration heating of small and medium regional boiler rooms, which provide heats for buildings with hot water cycle in coal-burning, gas-burning, oil-burning ways and via regional pipe network; (3) small gas water heater, which is a economical and practical heating solution if the natural gas can be selected as heating fuel material in the newly-built civil buildings; (4) direct electric heating, which is a technology applying all kinds of electric radiator and film indoor, allowing the home owners to make an adjustment flexibly according to the specific requirements of the home owners and possessing a 100% heat utilization rate in end device.

the results are consistent with the professional safety inspection results, prove the feasibility of dynamic fuzzy comprehensive evaluation model.
Conclusion This paper develops the fuzzy comprehensive evaluation dynamic model of bridge construction safety management status, combine it with a highway bridge construction safety management, the results are consistent with the professional safety inspection results, prove the feasibility and reasonability of this model.

At the same time, the initial conditions of construction and matters requiring attention during the construction phase are integrated and discussed, as well as issues such as the weights of design value, as a whole to consider, to minimize the error between the design and construction. 1 Introduction Energy-saving construction is the construction mode with the target of utilizing resources reasonably and recycled, conserving resources and reducing energy consumption for construction, which means during the process of construction, each part like the planning, design, construction, maintenance and other need to save energy such as water and electric to the maximum degree, and effectively increasing energy usage, reducing energy loss [1-3].
In addition, the progress of the construction need to be deployed scientifically, reducing the consumption of green areas in the water, which is an energy-saving construction method. 3 Conclusion At this stage, energy conservation and environmental protection and low-carbon energy consumption are the inevitable trend of the development of construction project, which needs related professionals in their work continued make reform and innovation, and integrate advanced science and technology, and make improved so as to achieve suitable for the construction.

For urban water supply, emergency water supply capacity building is the key to ensure security of water supply in the crisis conditions.
Analysis of water assurance level The total water resources and water status Total water resources Qujing located in the watershed zone of the Yangtze river and the pearl river.
From the amount of water resources, the water production of four reservoirs is about two times that of urban water consumption, and can basically meet the city's current water demand.
Water chemistry type is HCO3- Ca, the water quality reach class II water standards, it is quality groundwater sources.
In addition, instructing the relevant professional functions to set up observation points, for purpose of understand the dynamic changes in groundwater level and water quality, and maintenance of emergency water supply system to normal operation.

Deionized water was used throughout experiments.
X-3B stock solution (500 mg/L) was prepared in deionized water and kept at 4˚C.
Solution B was the mixture of water, hydrochloric acid and absolute alcohol.
