Current paper shows that buildings built with industrialized technology can deliver large energy and GHG emission reductions at low costs.
In this document, target values were identified for the reduction of greenhouse gas emissions, increasing renewable energy shares and for increasing energy efficiency, thus by 2020 the Europen Union should reduce the energy consumption by 20%.
The basis of the typology was the available statistical data on the establishments.
The data acquired from previous energy efficiency tenders were taken into account when developing the models.

Tucson, Arizona 85706, USA Email vshapovalov@mercorp.com Keywords: gasar, porous materials, high strength, pore structure, applications, low cost Abstract The paper summarizes new and published data and also deals with structure, applications, and properties of gasars - new porous materials based on gas-eutectic reaction which was establish in USSR in 1976-1980.
In a gasar with its monolithic matrix the reduction in the electric conductivity is almost strictly proportional to an increase in the amount of porosity.

To meet the requirements of enterprises in different developing phases, often using the latest technology under the circumstances that lead to existing many and various hardware, operating systems, middleware, programming languages, data storage, reusable redundant code in the enterprise.
This means that possibility of reduce the cost increase by resources cost reduction and resources reuse.

The results of the study provided reliable data for the controlled rolling and sizing processes for the production of the 36Mn2V steel pipes.
For this reason, the parameters of continuous rolling and sizing process for the production of the pipes were formulated according to the thickness reduction requirement of the pipe and optimized on the basis of results presented in the preceding sections.

Finally, curves of P-Q and P-η at 4600 r/min are forecasted through the analysis of the data, which provide references for reducing impact that condition alteration on fan performance and improving the efficiency of the fan.
However, there is a large vortex at the entrance of the third impeller, leading to inflow blocked and reduction of efficiency, as well as the impeller outlet.

Thixoextrusion, one of the thixoforming processes, has advantages of high productivity, reduction of the extrusion pressure and cost saving because of the low energy consumption compared with the conventional extrusion processes.
The heating temperature was set to the datum as thermocouple position ⓢ in Fig. 1.

In theory, any gas, capable of electrochemical oxidation and reduction can be used as fuel and oxidant in a fuel cell.
The data concerning the change of structure at elevated temperature is also ambiguous.
Hayashi et al. [66] obtained conductivity data on single and double doped perovskites and found that there is a compromise between the tolerance factor and the lattice free volume.
The knowledge of actual TEC data is important because LaGaO3 is polymorphic having orthorhombic structure at room temperature and it transforms to a rhombohedral symmetry at around 148 °C.
So, it was proposed that the internal LaMnO3-YSZ contacts are active for O2 reduction.

The starting point is the organization of the biophysical information obtained and represents a challenging process and a first approach through data collection process, based on the type of climate, necessary to be able to apply solutions on inspiration from nature to architectural solutions and to understand the contribution of biomimetic materials to the design culture.
The second factor concerns the current phase of the debate on environmental sustainability characterized by a new awareness: the need, on the one hand, of a radical change in the development model and a drastic reduction in the consumption of environmental resources of industrial companies and the observation, on the other hand, of the slowness and inefficiency of changes in the direction of sustainability, despite the considerable financial, technological and human resources put in place.
Climate bionics - reduction of energy consumptions.

The possibility to use photocatalytic paints and nano materials within the opaque panels, as in smart and efficient layers for innovative envelope, can allow reducing internal air pollution due the presence of occupants or for the use of toxic glue, formaldehyde or other harmful materials, will actively contribute to the CO2 and/or other chemical pollutants reduction [19] In the Technology Center Leitat in Barcelona (Fig. 8), the bioclimatic façade that acts as a filter between interior and exterior, an interface between the weather conditions outside and inside and the material of building envelope has photocatalytic proprieties, which help reduce, under the solar effects, the pollution and the decomposition of polluting city oxides (NOx).
