The Given

Planned and/or unplanned developments in the setting, which are directly or indirectly in connection to a certain profession or are of multidisciplinary character, have impact on initiation and steering of the course and direction of research campaigns of “vigilant” professional analysts and/or researchers of a profession, i.e. professions. It was the occurrence of the “vicious infection - SARS CoV 2” at the territory of Planet Earth which also initiated the subject professional research in the area of applied thermal engineering within two partial units which may be in interaction with the infection, i.e. which may also be in causal connection: “applied thermal engineering in building stock (only business and residential buildings)”- “sophisticated thermotechnical system integrated in a business or residential building”- “pathogenic microorganisms”. When general, professional and/or scientific public was faced with occurrence of plentitude of information, misinformation, interpretations, misconceptions, and/or ambiguities in the “black box of SARS CoV 2 pandemic”, the subject research was initiated in an analytical and principled manner with application of methods of analysis based on the “logic of rational action” in the given area. The aspects of the approach are adapted to the subject of the research, imperatively and consecutively imposed by the need for analysis and evaluation of causality between the given partial units and pathogenic microorganisms. In relation to the accepted partial units in the stage of utilization of the existing business or residential building for the dedicated purpose, the findings point that, inter alia, if such buildings were constructed as a result of conscientious, competent, responsible, and highly professional work of multidisciplinary builders and if they comprise adequate integrated sophisticated thermotechnical systems which have systematic, functional, and operating capability and which achieve satisfactory target function of the system, they do not “generate” pathogenic microorganisms, do not participate in their transfer, do not intensify their pathogenic properties and activity, do not contribute to occurrence of pandemics, do not jeopardize human health, and do not cause their mortality, etc. but are basically also not intended to “destroy” pathogenic microorganisms reaching the system from the outside and/or treated limited closed spaced within the building frequented by people off their working activities and/or pursuing their working activities, individually or in groups. Depending on the type of the current sophisticated thermotechnical system in the building, if necessary, it is possible to perform interventions aimed at reconstruction so as to “immunize” the system in a manner which may be recognized and designed by professional, competent, experienced, and dedicated thermal engineers. It needs to be noted that the subject exploration is conducted for deontological reasons, with the aim to promote theory and practice in the given.

The METAPOLIS as the polycentric network of urban–rural settlement is undergoing constant transformation and urbanization processes. In particular, the associated imbalance of the shrinkage and growth of different settlement types in relative geographical proximity causes negative effects, such as urban sprawl and the divergence of urban–rural lifestyles with their related resource, land and energy consumption. Implicitly related to these developments, national and global sustainable development goals for the building sector lead to the question of how a region can be assessed without detailed research and surveys to identify critical areas with high potential for sustainable development. In this study, the TOPOI method is used. It classifies settlement units and their interconnections along the urban–rural gradient, in order to quantify and assess the land-uptake and global warming potential driven by residential developments. Applying standard planning parameters in combination with key data from a comprehensive life cycle assessment of the residential building stock, a detailed understanding of different settlement types and their associated resource and energy consumption is achieved.

Abstract. Reducing the demand for non-renewable resources and the resulting environmental impact is an objective of sustainable development, to which buildings contribute significantly. In order to realize the goal of reaching a climate-neutral building stock, it must first be analyzed and evaluated in order to develop optimization strategies. The life cycle based consideration and assessment of buildings plays a key role in this process. Approaches and tools already exist for this purpose, but they mainly take the operational energy demand of buildings and not a life cycle based approach into account, especially when assessing technical building services (TBS). Therefore, this paper presents and applies a methodical approach for the life cycle based assessment of the TBS of large residential building stocks, based on semantic 3D city models (CityGML). The methodical approach developed for this purpose describes the procedure for calculating the operational energy demand (already validated) and the heating load of the building, the dimensioning of the TBS components and the calculation of the life cycle assessment. The application of the methodology is illustrated in a case study with over 115,000 residential buildings from Munich, Germany. The study shows that the methodology calculates reliable results and that a significant reduction of the life cycle based energy demand can be achieved by refurbishment measures/scenarios. Nevertheless, the goal of achieving a climate-neutral building stock is a challenge from a life cycle perspective.

Building Safety

A Rapid Visual Damage Assessment was initiated in the direct aftermath of the 2015 Gorkha earthquake to assess the safety and damage of residential buildings in the areas affected by the earthquake. Over 30,000 paper assessment forms have been subsequently digitized. The collected data set allows comparison of the observed damage to the residential building stock to the damage expected using existing fragility curves. Under certain conditions and respecting certain limitations, the post-earthquake building safety and damage data can be used to update the existing fragility functions for the Nepalese building stock. Recommendations are made for the improvement of post-earthquake building safety assessments in Nepal in order to: (1) make data collection more consistent, (2) increase the accuracy of the collected data, and (3) make more effective use of the collected data after future earthquakes.

This article examines the peculiarities of formation of residential areas along the Chinese Eastern Railway (CER); analyzes the pattern of settlements; and examines the architectural nuances of residential buildings. The object of this research is the architectural urban development peculiarities of Russian railroad stations on the territory of Northern Manchuria. The subject of this research is the residential environment in the settlements along the Chinese Eastern Railway. The chronological framework covers the first three decades of the XX century: beginning of construction and first years of exploitation of the railway, characterized by active urban development process and creation of full-fledged environment for accommodation of construction workers, railway workers, migrants from Russia, Southern Manchuria and mainland China. The theoretical foundation for this study consists in the systemic-axiological approach, according to which the culture defines the system of materialistic and spiritual values passed from one generation to another, and allows determining the value grounds of cultural interaction and its panhuman significance. The work explores the peculiarities of architecture and urban development in the settlements along CER. Study is carried out on the construction process of the railway and living conditions of first workers, approaches towards design of the stations of the main line and the southern branch, as well as architecture of residential building of the settlements. The author considers the impact of Russian environment upon the existing Chinese cities, and the use of the traditional Chinese approaches in the projects by the Russian engineers and architects.

Definition Of

More than the 60% of the Italian residential building stock had already been built by 1974, when seismic codes were enforced on a minimal part of the country. Unreinforced masonry buildings represent most of that share, but they are typical for each region, in terms of both materials and structural configurations. The definition of ‘regional’, i.e., more specific, vulnerability and exposure models are required to improve existing forecast models. The research presents a new geographic information system (GIS)-based multilevel procedure for earthquake disaster prevention planning at urban scale; it includes multicriteria analysis, such as architectural types, structural vulnerability analysis, microzonation studies, and socio-economic aspects. The procedure has been applied to the municipality of Pordenone (PN), a district town of the Friuli–Venezia–Giulia region, in Northeast Italy. To assess the urban seismic risk, more than 5000 masonry residential buildings were investigated and common types within sub-municipal areas and exposure data were collected. Simplified mechanical analysis provided a ‘regional’ vulnerability model through typological fragility curves. The integration of results into GIS tool permitted the definition of cross-mapping among vulnerability, damage scenarios (conditional and unconditional) and exposure (seismic losses, casualties, impact), with respect to various earthquake intensities expected in the town. These results are presented at different scales: from the single building, to submunicipal area and to the entire town.

AbstractIn the context of the Algerian energy policy, and through the review of the Algiers’ residential building stock, this paper explores the correlation between the energy consumption of gas and electricity with urban density. Based on a holistic approach of the 57 Algiers’ municipalities, the analysis is organized in two ways. Firstly, the spatial approach is conducted within a GIS implementation, carried out based on the 2013 aggregated annual energy consumption data. The cross analysis of Electricity and Gas consumption and density of population within a GIS spatial distribution approach shows effectively a strong correlation between urban density and energy consumption with a Pearson correlation of −56% and −65% of the Electricity and Gas consumption in the urban municipalities, respectively. Also, the household located in the suburban municipalities consume clearly more energy than the urban centered ones. Based on the electricity and gas consumption, density and carbon footprint we have clustered, within a PCA, the Algiers’ municipalities into three profiles: the “thrifty”, the “intermediate” and the “wasteful” profile.

Urbanization and technology have proven to be detrimental to the environment. Buildings contribute a significant portion of this damage. This issue motivated governments, builders, engineers, and architects to seek ways to reduce buildings’ environmental footprints. Leadership in Energy and Environmental Design (LEED), developed by the U.S. Green Building Council (USGBC), is one of the most widely used strategies to ensure energy efficiency and a clean environment in buildings. In Afghanistan, where there are no active regulatory frameworks for energy saving and efficiency for the building sector, it is imperative to promote the transformation of the building industry and practices towards sustainability. In this regard, the role of the residential building sector is of utmost importance due to its major share in the country’s energy consumption and GHG emissions profile. Thus, this study assesses the energy efficiency and environmental impact of existing buildings in Kabul city concerning the LEED rating system. This research suggests practical steps to improve the sustainability of the residential building stock in Kabul city. Robust sets of data on existing residential buildings in Kabul are collected, classified, evaluated, and compared to LEED standards. This research reveals and concludes that most of the existing buildings in Kabul city are in poor conditions and do not meet the minimum requirements to be a candidate for LEED certification. A detailed analysis of the results has led to recommendations on how these buildings could improve to meet the LEED criteria. This is the first study of its kind conducted for Kabul city residential building. Considering the cross-sectoral nature of the building industry, the findings of this study will contribute to many other areas such as water, transportation, ICT, health, energy and the environment.

In the early 2000s, the Korean government mandated the construction of only zero-energy residential buildings by 2025 and for non-residential buildings from 2030. Two decades since the start of building energy policy enforcement, Korean experts believe that it is time to evaluate its impact. However, few studies have systematically and extensively examined the energy consumption characteristics of the non-residential building stock. In this study, a framework development is implemented for defining non-residential prototypical office buildings based on Korea’s first large-scale non-residential building survey result from the Korea Energy Economics Institute (KEEI). Then, a detailed building energy model of the defined prototypical building is constructed to verify the model’s energy estimation against observed energy consumption. As an application of the model, a case study for energy policy evaluation utilizing the constructed prototypical building model is presented. Every researcher and county may have their own circumstances when gathering definition data. However, by using the best available representative data, this suggested framework may result in informed decisions regarding energy policy development and evaluation. In addition, the mitigation of greenhouse gases from buildings may be expedited.
