The effective using of material resources involves the regulation of non-renewable natural resources, the increasing the share of renewable sources, including recycling and reutilization existing recycled building materials. [1, 2] The global orientation and achievement of the objectives of sustainable development is extremely difficult and revolutionary process leading to a fundamentally different principles and forms of contemporary industrial civilization.
The sample includes energy passive houses with light, massive or combined constructions of heterogeneous building materials built in the years 2004-2013.

The information transmission method need not depend on the presence of drilling fluid and property of drilling fluid, not affected by the magnetic material of formation, which provides favorable conditions for information transmission, this is the advantage of this information transmission method.
Displacement equation can be expressed as (1) (2) Fig.1 Model of complex drillstring Where, is drilling string acoustic transmission displacement, and is normal component of displacement of the incident wave and reflected wave, is angular frequency, is frequency The axial force on the cross section can be expressed as (3) Where, is the axial force on the cross section, is cross section area, is compressional wave velocity, is material density Drill pipe and the joint interface should meet the following conditions: the normal component of displacement of is continuous and the normal force too. where interface
