Energy saving can be maximized by rectifying the intermediate conversion processes involved during the utilization of solar energy. The system eliminates the transformation of electrical form of solar energy into another form by directly utilizing its electrical energy in the management and control of power supplies obtained from renewable (solar) and conventional (mains) energy sources. A current control scheme is presented in which current delivered by solar supply is used to control the current in mains supply in such a way that both currents are inversely proportional to each other. Any increment in solar current opposes mains current in the same proportion and vice versa. A balanced common physical output is resulted from the electrical load supplied by each source separately. A natural variation in solar radiation is utilized to fluctuate the solar current which is further used to change the mains current. Energy saving is maximized in this supply management by the optimal utilization of solar energy.

China building energy-saving technology is in the early stages of the development with energy high consumption and low energy efficiency. It is especially important to control each link of the building energy-saving for energy conservation. In construction of the envelope structure exists Some prominent effects ，such as the compilation and implementation of the construction technology, the review of design alteration, the performance measurement of materials and components, and control of construction technical measures, we should be implemented related inspection and control in all stages of the implementation process.
