“…This type of connection in the described OWT-67 system creates a bringing technical problems linear thermal bridge (structural). The tests of the structural thermal bridge of the prefabricated system of the balcony slab of the system were carried out as a thermographic quality assessment [10,[14][15][16][17].…”

This article presents a non-invasive tests report of precast cantilever balcony support in OWT-67 large-panel system. During field testing, the balcony's reinforced concrete structure was subjected to radiometric analysis in the context of thermal energy distribution as well as from the point of view of mycology - to the possible presence of spores of domestic fungi. The temperature distribution tests carried out by means of the electromagnetic wave detection in the infrared spectrum clearly confirmed the significant losses of thermal energy caused by the effect of the thermal constructional bridge located in the balcony. Mycological diagnosis was carried out using the rapid test of the Mycometer bacterial meter, which allows fluorimetric evaluation of the presence of the enzyme presence in filamentous fungi. In the conducted study, no spores of the house mushroom were found on the inside surface of the Z-type balcony supporting beam as a place where condensation of water vapor may occur. The summary also presents a design solution that allows to eliminate this physical problem.

“…Bad indoor thermal experience accounts for a large proportion of householders' complaints [3]. Consequently, home renovation has become a common choice for improving their indoor thermal environment, which typically includes window replacement, better insulation, installation of a more efficient heating system, and improvements in house airtightness and natural ventilation, using mechanical ventilation systems [4]. However, improvements in thermal indoor environments are hampered by an outmoded renovation design process that fails to efficiently coordinate design aspects (architectural, facilities, structural, and environmental) while problem-solving issues and handling the feedback loop in a timely manner.…”

Integrating Animated Computational Fluid Dynamics into Mixed Reality for Building-Renovation Design

In advanced society, the existing building stock has a high demand for stock renovation, which gives existing buildings new lives, rather than building new ones. During the renovation process, it is necessary to simultaneously achieve architectural, facilities, structural, and environmental design in order to accomplish a healthy, comfortable, and energy-saving indoor environment, prevent delays in problem-solving, and achieve a timely feedback process. This study tackled the development of an integrated system for stock renovation by considering computational fluid dynamics (CFD) and mixed reality (MR) in order to allow the simultaneous design of a building plan and thermal environment. The CFD analysis enables simulation of the indoor thermal environment, including the entire thermal change process. The MR system, which can be operated by voice command and operated on head-mounted display (HMD), enables intuitive visualization of the thermal change process and, in a very efficient manner, shows how different renovation projects perform for various stakeholders. A prototype system is developed with Unity3D engine and HoloLens HMD. In the integrated system, a new CFD visualization method generating 3D CFD animation sequence for the MR system is proposed that allows stakeholders to consider the entirety of changes in the thermal environment.

“…Each method includes on-site inspection, diagnostic and computational analyses. The final stage of the 3-year project has focused on the practical application and validation of developed methodology in real buildings, described in detail in the published Handbook Vol.5 [7] and presented in scientific/research articles [8,9,10,11,12]. This paper presents the insights on a comprehensive on-site diagnostics based on an exemplary multi-family building.…”

The article presents the case study of the comprehensive diagnosis of an existing residential building with natural ventilation. The results of quick diagnostics of thermal insulation of the building, the heating system, ventilation, domestic hot water preparation and the quality of the environment in the rooms were presented. Based on the data obtained by measurements, the energy performance of the building was prepared using the building certification calculation method. The energy performance of the building was also prepared using the developed method of determining energy performance based on measurements.
