nergetic efficiency as well as the protection environment can be studied individually and coupled with the use of renewable energy sources which have an increasingly important part in global energy production. In the same time, the implementation of clean energy sources have an essential role to protect the surrounding environment. In the regard of the study of interior and exterior air quality, filtration methods witch active coal propose to reduce the necessary energy in ventilation and climate systems of buildings. As a result of research in this domain have appeared in this domain, multiple requests within the industry to implement filters with active coal in evacuation air vents in interior spaces and in the frame of air treatment facilities, reducing the fresh air intake having a significant negative impact in ventilation systems. Within the laboratory there can be performed similar experiments that were also performed in modern labs on global level because of the acquisition of chromatograph with a mass detector, which with the help of, the determination of penetration curves of activated coal and other construction materials. Combining the advantages of numeric modeling with the experimental parts, development models can be validated, especially in the domain of multiple mixed pollutants and the influence of humidity on absorption, less studied cases which are of interest in the international research domain. The study of an air evacuation vent, but with absorbent materials is as well highly studied for simple cases, in case of a single compound in the air, and this newly created laboratory can be extended, for more complicated cases (more compounds and influenced by the humidity), which can have applications in the industrial domain. All the listed research themes have as conclusion the reduction of consumed energy in ventilation-climate systems which have an important part of the total of energy in a building. For the study of influence on the pollutant transfer from the exterior of the populated space to the interior of the bought mobile laboratory can be capable of measuring the exterior pollution level. This laboratory can be utilized for a multitude of pollutants: organic volatile compounds NO, NO2, SO2, CO, H2S, O3 and particles. As such, there can performed prediction models for the pollutants interior-exterior cycle. Another use of this mobile lab will be the study at emission of a single or multiple pollutants, then the measurement at emission of the pollution level, acting like this resulting in the fabrication of pollution prediction patterns on the basis of the obtained experimental data obtained with the measurement devices. The evaluation of noise and vibration through numeric modeling and experimentation also represent a point of interest on a national level. Acoustic specialists utilize specific descriptors and different measurement units in audio-level measurement and on the noise generated impact. The noise is usually defined as an unwanted sound that interferes with verbal communication and audio perception or which can affect the human behaviour when it exceeds certain limits. In certain conditions, the noise can determine the loss of 8
hearing, can interfere with human activity and, in different ways, can affect the human health and behaviour. Rehabilitation measures of installations which constitute as a noise-producing source represent an important research theme which will be developed in this lab.
The study of renewable energy sources constitutes a continued increase caused by the continued implementation in national energy production systems, their ponder being very significant(elecyric energy, thermal energy and cogenerated energy). The functional study of regenerable sources which provide thermal or electric energy represent a first step towards complex studies, for example hybrid systems or even innovations and inventions in the domain. Validating numerical models utilising experimental data brought by a solar and photovoltaic thermic system make possible the study functional experimental and numerical parameters of a photovoltaic , thermal-solar or geothermal, in the scope of their optimisation. The research laboratory of energetic efficiency and the study of clean energy sources, upon the upgrade to the latest equipment, can be used to perform complex research in this exquisite domain, as following: 1.
