According to the survey data, lush trees can block 50% ~ 90% of the solar radiation heat.
For the south windows, the choice of suitable varieties or layers of glass and take effective measures to reduce energy consumption, under the premise may be appropriate to increase the window size, to take full advantage of solar radiant heat in winter; the other window in meeting room’s indoor lighting, ventilation, based on the appropriate reduction in window size, reduce energy consumption, The Area ratio of window to wall should meet the national norms requirements: "North 0.25, east/west 0.3".
Slope roof ventilation window before and after the set, closed in winter, so that the lower part of the roof space to form a closed insulation space, open in summer, so that the internal hot air under the action of the natural wind flow to the outdoor discharge, a heat insulation space Paying much attention to the thermal insulation of balcony, reducing the northwest wind in winter for indoor direct penetration, and make the appropriate reduction in overhang length, so as not to affect households in the winter sunshine the next block.

Given the many possibilities to substantially reduce buildings’ energy requirements, the potential savings of energy efficiency in the building sector would greatly contribute to a reduction of energy consumption.
The implications of such potential reduction should not be underestimated, as the scale of energy efficiency in buildings is large enough to influence security policy, climate preservation and public health on a national and global scale [1].
The data only calculates building energy consumption in the process of usage, not including energy consumption of building material production and building construction.

Data was collected till no successive change in weight was observed.
The reduction in permeability is strongly related to a reduction in the diffusion coefficient imposed by the presence of crystallites.

When replacing the steel armor of an armored hull with aluminum one, the reduction in the weight of an armored hull is achieved due to the higher hardness of aluminum plates and the withdrawal of some hard parts [3].
The further effective enhancement of protection with the mass conservation or reduction is associated with the increasing hardness of a barrier by creating aluminum + ceramics composites.
The results of such stand tests as well as the analysis of literature data have shown that the breaking of conventional aluminum alloys occurs without destroying the core [1, 2, 9 - 11].
