A non-destructive method for measuring moisture within porous building materials is presented. It is based on the detection of the backward angle scattered gamma-rays of a 241Am source, with a LaBr3:Ce scintillator detector. An example of application of this method is given by measuring the moisture in bricks (building material) with various water contents. The method is suitable for the examination of building walls (houses, historical monuments) and of building material samples.

Geographical Information Systems (GIS) can be used in biological conservation as decision support systems, integrating the spatially referenced CORINE land cover and using data to assess whether natural protected areas cover particular types of ecosystems and/or biogeographical diversity. This study analyzes whether the Natura 2000 sites, which are Special Protection Areas and Special Areas of Conservation declared in Romania cover the diversity of wetlands and coastal areas habitats, as well as the biogeographical diversity. Results suggest that the situation is particularly good in the steppic and Black Sea regions, but could be improved in the continental, pannonian and alpine region. Increasing the surface of existing protected areas and declaration of new sites is already on the governmental agenda. The limitations of this methodology are related to the frequency of updating CORINE data at the scale of the entire continent.

This paper is focused on the effect of elastomer supporting of the tram railways used for damping vibrations and noise transmitted to the surrounding buildings. For this, the experimental methods under dynamic regime both stationary and transient attaining the resonance point are presented. In this way the dynamic system parameters, namely: dynamic stiffness, the fraction of critical damping, coefficient of dissipation (hysteresis) were determined. Thus, the damped free vibration method was used and the controlled dynamic method with monotone increasing variation for the excitation frequency for stiffness and damping characteristics of rubber manufactured by various recipes. Finally, the paper presents experimental results obtained in the laboratory and the degree of noise reduction produce by tram railway in large urban areas of cities in Romania.

Interior soundproofing is a requirement for buildings with special activities where the level of vibration and noise shall be minimal. This paper specifies the essential requirements for the definition of performance vibration isolation from the outside of buildings for special purposes. This category includes operating rooms, facilities and premises of "white rooms", rooms processing, calibration and mounting the semiconductor where the level of vibrations from the urban environment and/or industry should be below the allowed threshold. In this context, we detail the dynamic model of a building placed on elastomeric elements for which are set the physical and geometric conditions by decoupling and reduction their frequency in ratio 1/4 .... 1/6 of the excitation frequencies. Also, are set the equations of motion for the externally excited system in order to evaluate the level of forced vibrations.

Contemporary architecture is more often thought about in the terms of self-sustainability and price efficiency. Choice of materials and the overall design including the building structure and the enclosures, its energy systems, the reuse of resources and the minimum waste production are discussed all over the world. Implementing buildings in natural sites or in sub-urban communities that are not connected to the usual urban facilities is always a challenge if we intend to use sustainable strategies. Our approach describes a case study of a design strategy based on a few general principles, crucial in optimizing material and energy consumption and waste and emissions reduction for a new construction. We will follow the interdisciplinary approach of the design process analyzing how each step taken to a certain direction affects the entire planning stage, influencing also the constructive systems. Also we will show how every used element influences the processes of the building with certain constraints for the architectural approach, especially in terms of functional and aesthetic valences. © (2013) Trans Tech Publications, Switzerland.

The cula house, a type of fortified boyar dwelling prevalent in the XVIIIth century in south-western regions of Romania, is one of the most intriguing typologies in traditional Romanian architecture. Halfway between fortified tower and dwelling, with a relatively brief history and disputed architectural lineage, the cula house makes for an interesting case study because it represents the capacity of traditional Romanian architecture to assimilate foreign influences while remaining autochthonous. The paper outlines the history, characteristics and uniqueness of this architectural program, less known beyond the borders of Romania. © (2012) Trans Tech Publications.

Modern Movement architecture employed new materials to deal with social challenges and industrial production. Today environmental problems arc the challenge. Resilience to neural hazards, including climate change, is such one, Gcoicxtiles are employed in largp landscape (ash/garbage deposits, river sides}, but planting on building surfaces is possible. We focus on green walls/roofs lor emergency housing, including reshaping of temporary propping systems. Green walls allow integrating parcels remaining empty after the collapse of buildings through Pocket Parks. The earthquake impaet becomes urban rcstrucluralion occasion. A special support skeleton for the earth&seeds&geotextile in green wall installations will be designed, and later pattented. © Springer Science+Business Media Dodrecht 2013.

Recent developments in computational design tools have bridged a gap between a well-established parametric building modeling[1] and analysis or simulation software such as EnergyPlus[2], Radiance[3], Daysim[4] and OpenStudio[5], opening up the possibility for architects to use the computational power to model and simulate real environmental behavior of the architectural artefact and its components. Now architects are able to evaluate the behavior of a project, whether it is a building, a city, a landscape or infrastructure and a new road towards an architecture based on performance is opened[6]. Therefore we can put the idea of performance as a precedent to shape development and the architectural form becomes informed by the performative aspects. We can use various computational tools in order to gather qualitative and quantitative aspects of the architectural artefacts performance in the early stages of design, and we can go further from just optimizing a form after it has been defined. This paper will discuss the implications of parametric modeling and energy analysis in architectural design and will present the authors research in developing architectural forms using the above described tools.

In this contribution we wish to address the subject of the tectonics when employing reinforced concrete as a material. One aspect is learning from large openings, as the structure of the nave transferred to the gaiola pombalina in the local seismic culture. Architects of the time as well, a connection between reinforced concrete and timber. This connection to timber should be followed further, in dealing with shape in earthquake vulnerability. We did a study on this as well, outgoing from deconstructing the traditional-modern binome, so what is traditional local seismic culture and what is modern engineering solution. Our approach is different, as that one looks at the influence of strengthening on the building, while we are looking on a form language from the point of view of the architect in which seismic strengthening can be integrated, so a search for the shape of the material as the essays at the begin of the 20th century did. © 2013 Taylor & Francis Group.

Mendelsohn's Einstein tower is considered to express through its shape the adequate form for concrete, but it was mainly done out of brick and iron. Apart of the philosophy of the material, the real technical employment is worth a look. To the time of Art Nouveau reinforced concrete was employed in the Hennebique system. An urban scale example is the XX September boulevard in Genova. The Athenée Palace Hotel in Bucharest, which started as a Hennebique system was transformed into a modernist building by Duiliu Marcu is an example of intervention. Reinforced concrete is documented also in the archives on the works of Béla Lajta in Budapest, highlighting the play of light and heavy, as it was in Loos' architecture. Not to forget is Joze Plecnik's contribution: the first church in reinforced concrete in Vienna, finding an own language which highlights the difference between a hall and a storey-wise construction. © 2013 Taylor & Francis Group.
