Dynamic Thermal Properties of Uninsulated Rammed Earth Envelopes
No full textThe work questions the significance of the steady-state R-value for high mass wall systems through experimental analysis of the thermal behavior of two stabilized rammed earth building components representing a building envelope subjected to variable temperatures in the form of 24 hour cyclic sinusoidal inputs. It shows that when the environment temperature is used to quantify the thermal fluctuation of a zone the response of the walls surfaces to energy cycles can be determined by dynamic thermal transfer properties expressed in accordance with EN ISO 13786: 2007 relating cyclic heat flux to cyclic temperature variations

Functionality and Sustainability Through the Planning Process of a Contemporary Sport Center
No full textThis paper presents the planning issues of a contemporary sport center through the award-winning plan of the A+ Építész Stúdió on the architectural competition for the Sport Center of the National University of Public Service. The complex urban situation, the architectural shaping of the new, large-scale sport complex between the historical Orczy Garden and the urban texture of the Józsefváros was a serious challenge. To the success of the competition plan a special approach was needed, which was synthesizing the respect of the heritage and values of the past, the contemporary designing principles and the progressive, sustainable architectural attitude of the future. Although the plan will not be realized, the applied architectural solutions can be instructive in the designing process of similar contemporary sport buildings
Wind profile and shear stress at reed-open water interface – recent research achievements in Lake Fertő
No full textThe effect of emergent aquatic canopy on over-lake wind field was investigated through detailed field measurements. The aerodynamic roughness length above reed canopy and above open water was determined from eddy-covariance data. It was found that the aerodynamic roughness length at short fetches could be more sufficiently estimated from wave age relations than from the logarithmical profile formula, indicating that near the canopy wind profile might deviate from the theoretical logarithmical form. The presented calculations lead to an improved understanding of the wind profile realignment and wind shear stress development at the interface of the characteristic lake zones, also enhancing the accuracy of the modeling of various wind-induced processes
Physico-chemical water properties and flora diversity under the old mining load influence (Rudnansky creek, Slovakia)
No full textMining and processing activities in the former mining Middle Spis area caused serious environmental problems. The aim of the study is to determine the content of heavy metals (Cu, As, Pb, Fe, Hg) in water and describe the flora diversity along the Rudnansky creek, which flows through the area. Chemical (pH) and physical (water conductivity, oxygen saturation) water properties were also evaluated. High values of copper and mercury were determined at the localities close to the tailing pond and mercury processing plant. Presence of plant species resistant to heavy metals, such as Calamagrostis epigejos, Arctium lappa, Cirsium rivulare, Geranium palustre, indicates toxic element pollution
Waste-based biofuel technologies in Finland — Current research and industrial activities
No full textFurther to Directive 2009/28/EC on the promotion of the use of energy from renewable sources, the share of biofuels in transport should rise to a minimum of 10% in Member States by 2020. In Finland, the goal is set at 20%, and it is estimated that this can be produced entirely in domestic factories, as long as the projects already underway will be successful and additional industrial-scale biofuel plants would be built. The paper reviews the state of projects underway in Finland, and outlines current research activity in promoting waste and by-product — based biofuels
