Currently the United Kingdom to promote passive solar house without external mechanical action, heat-absorbing insulation materials of construction for the media, the use of natural cold and hot air exchange, to the use of solar energy.
It involves the disciplines of Architecture --- urban planning, architecture, building physics (architectural acoustics, building optical, thermal engineering construction), construction structure, building materials, building water supply and drainage, building heating and ventilation, building electrical, landscape architecture, municipal engineering and other professional, it also involves physical geography, meteorology, and environment-related subjects and residents other factors.
Conclusions Residential building energy efficiency is a systematic, not only with architectural planning and design are inseparable, but also to many other areas, such as equipment design, management, application of new technologies, new materials, renewable energy development and utilization, construction division only them into account, can improve the residential building energy saving.

Introduction Rock is a multiphase material composed of several kinds of mineral grains, cements, micro-pores and cracks.
Brittle or ductile materials should be studied on the meso-level.
This experiments were conducted in the state key laboratory of nonlinear mechanics (LNM) of Institute of Mechanics, Chinese Academy of Sciences.
