V. CONCLUSION
As conventional energy being exhausted, it is urgent to
research, develop and utilize the green regenerative energy
sources, which is represented by the wind energy and the
solar energy. For example, in European Union with 15
member countries, its total target in 2010 is to make the
utilization of green energy reach 22% among the total
power production.
Based on the ecological theory, and following the
principles of ecological balance, the sustainable
development and the optimization of the system efficiency,
the objective of the control is to make the substance
energy sources be transformed orderly and circularly in the
building system, also to construct the house to be a small
ecological system, thus we can get an intellectualized and
ecological resident environment with high efficiency, lowconsumption,
low-scrap and light pollution. This is just the
requirement of the present time.
The new research subjects are coming forth endlessly with
the development of green energy source and ecological
environmental control.
