In the practical management,searching for profit growth point and making profit from building materials and equipments to increase income and reduce expenditure is a difficult problem for construction enterprises.

To insure the irrigation water in land development and consolidation projects and to realize sustainable use of water resource, based on the study of the water resource condition in Hengshui City, this paper proposes the fundamental approach of “increase income and reduce expenditure", systematically introduces the technological methods of it, and t.

Integrated benefit assessment and analysis on measures of saving water and increasing the sources;

The article establishes a mathematical model of energy conservation measures of structures of public buildings with the consuming cold amounts as the parameter of cost during the whole life cycle and with the target of balance between the initial investments and the cost amounts.

An outline is given of the ICI-AMV Process and the KBR Process for the ammonia unit, with their respective characteristics,and an analysis is given of the energy conservation measures adopted by the two processes.

Energy-Saving Measures in Central Air-Conditioning System;

Analysis of energy consumption and study on energy-saving measures in design of large refineries

Combining with the characteristic and requirement of the building, in the design of this project, several energy-saving measures were used in this project, at the same time because this project served in a public entertainment place with relative closed space, good ventilation condition can make indoors air environment better in either air-conditioning seasons or transition seasons.
