Introduction: Heritage conservation attracts wide attention worldwide. Jordan has many heritage buildings that were preserved, rehabilitated, and adapted to new functions. However, these conservation efforts could not solve the energy consumption problem or maintain the economic and financial balance, thus reducing building efficiency, slowing down the conservation activity, and forcing us to consider new solutions, especially since Jordan has limited energy sources. Integrating smart technologies in historical buildings is widely effective in achieving the sustainability of their historical, symbolic architectural values. Purpose of the study: We aimed to explore the potential integration of smart technologies in cultural and heritage buildings. Methods: We suggested an alternative solution -adopting the smart building concept in the Abu Jaber Museum in Al-Salt (which recently got on the UNESCO World Heritage List since it has more than 1000 heritage buildings), using an automated lighting control system. Approach: We deployed the qualitative method and case study approach to investigate the potential of adopting the smart building concept in the historical building in Al-Salt, Jordan. The study sheds light on the possibilities of utilizing smart technologies in historical buildings in Al-Salt.The findings indicate that smart technologies can offer great opportunity in preserving the architectural heritage and raising the efficiency of heritage buildings. Novelty: The study provides a framework based mainly on automated lighting systems in historical buildings. For the first time, the focus was on historical buildings in Jordan and their performance.

Introduction: The article addresses the possibility of using universal energy-efficient engineering and technological solutions in mass housing construction, regardless of the climatic region of construction, with account for modern development in Saint Petersburg (Russian Federation) and Münster (Germany). The article not only considers improvements in building technologies used in modern housing construction but also offers an overview of the latest energy-efficient materials and structures. Purpose of the study: We aimed to introduce energy-efficient solutions in housing construction using innovative technologies and materials. In addition to theoretical materials, practical calculations will be presented, clearly showing the advantages and disadvantages of various engineering and technical solutions. Methods: In the course of the study, we used a) a comparative analysis of physical and thermal properties as well as strength characteristics of building materials used in mass housing construction; b) a problem-logical method to analyze possible typical space-planning and structural solutions for the design and construction of buildings, with account for climatic conditions and geographical features of the construction region, in compliance with the basic principles of modern sustainable construction, energy and environmental standards, economic efficiency of the solutions used, in accordance with international European LEED and BREEAM and Russian GREEN ZOOM standards. Results: We propose to introduce, along with the already well-known and time-tested ones, innovative patented solutions in materials and construction technologies both in private and mass housing construction in the countries under consideration: Russian Federation and Germany. Discussion: The discussion of field tests and implementation of the latest building materials in housing construction clearly demonstrates the importance of international cooperation in this field at various levels. As a consequence of the growing volume of housing construction and energy consumption, there emerge new stricter requirements and standards for the quality of materials produced and their technical characteristics, as well as a variety of decorative solutions enabling the construction market to be competitive and meet the over-demand requirements of the rapidly developing industrial society, while necessarily taking environmental protection measures, including those on conservation and mindful use of natural resources.

Der Beitrag befasst sich mit dem gebetteten Spannbogen, einer neuartigen Unterstützungskonstruktion zur Erstellung einer freitragenden Gewölbebewehrung für die Tunnelinnenschale im bergmännischen Tunnelbau. Dabei wird der üblicherweise verwendete Tragbogen durch einen Spannbogen ersetzt, welcher sich über Abstandhalter gegen die Tunnellaibung verspannt und somit planmäßige Druckkräfte auf das Abdichtungssystem bzw. den Spritzbeton als Abdichtungsträger überträgt. Im Wesentlichen resultieren diese Druckkräfte aus dem Vorspannen des Spannrings und dem Eigengewicht der angeknüpften Bewehrung. Die Größenordnung dieser Druckkräfte wurde bisher lediglich überschläglich abgeschätzt. Im Rahmen der hier vorgestellten Untersuchungen werden diese messtechnisch erfasst und hinsichtlich ihres Gefährdungspotenzials genauer beurteilt. Weiterhin wurden diverse Detailpunkte dieser Konstruktion im Labor untersucht.
