To improve the lack of data, a large scale study was carried out using a Post Occupancy Evaluation of 1,416 building occupants. Several criteria describing the needs of occupants were evaluated with regard to their subjective level of relevance. Additionally, we investigated the degree to which deficiencies subjectively exist, and the degree to which occupants were able to accept them. From the data obtained, a hierarchy of criteria was created. It was found that building occupants ranked the physiological needs of air quality and thermal comfort the highest. Health hazards such as mould and contaminated building materials were unacceptable for occupants, while other deficiencies were more likely to be tolerated. Occupant satisfaction was also investigated. We found that most occupants can be classified as satisfied, although some differences do exist between different populations. To explain the relationship between the constructs of what we call relevance, acceptance, deficiency and satisfaction, we then created an explanatory model. Using correlation and regression analysis, the validity of the model was then confirmed by applying the collected data. The results of the study are both relevant in shaping further research and in providing guidance on how to maximize tenant satisfaction in real estate management.

Having examined the effect of buildings on energy consumption, these studies indicate that the physical form of a city has a notable impact on the amount of energy consumed in its spaces. The present study identified the variables that affected energy consumption in residential buildings and analyzed their effects on energy consumption in four neighborhoods in Tehran: Apadana, Bimeh, Ekbatan-phase I, and Ekbatan-phase II. After extracting the variables, their effects are estimated with statistical methods, and the results are compared with the land surface temperature (LST) remote sensing data derived from Landsat 8 satellite images taken in the winter of 2019. The results showed that physical variables, such as the size of buildings, population density, vegetation cover, texture concentration, and surface color, have the greatest impacts on energy usage. For the Apadana neighborhood, the factors with the most potent effect on energy consumption were found to be the size of buildings and the population density. However, for other neighborhoods, in addition to these two factors, a third factor was also recognized to have a significant effect on energy consumption. This third factor for the Bimeh, Ekbatan-I, and Ekbatan-II neighborhoods was the type of buildings, texture concentration, and orientation of buildings, respectively.

Sie repräsentieren die zur Bearbeitung erforderlichen Eigenschaften eines Bauwerks in einer an die spezifische Aufgabe angepassten Form. Zwischen den verschiedenen zur Abbildung des Bauwerks eingesetzten Modellen bestehen fachliche Zusammenhänge bezüglich der darin abgebildeten Aspekte. Diese Abhängigkeiten werden in der praktischen Planungsbearbeitung gegenwärtig auf Grundlage von Erfahrungswerten, normativen Vorgaben und vereinfachenden Annahmen berücksichtigt. Die detailliertere Modellierung von Bauwerkseigenschaften führt zu einer engeren Verzahnung der verschiedenen Modelle. Um eine fachliche Inselbildung zu vermeiden, ist eine entsprechend angepasste Abbildung der zwischen den einzelnen Modellen bestehenden Beziehungen erforderlich. Mit den steigenden Ansprüchen an eine Bearbeitung von Ingenieuraufgaben gewinnt eine über den Zweck der Bereitstellung ausgewählter Informationen zum Bauwerk und der Unterstützung eines Datenaustauschs zwischen verschiedenen Fachplanern hinausgehende datentechnische Abbildung an Bedeutung. Dies setzt eine Diskussion der Anforderungen an eine solche Beschreibung aus fachlicher Sicht voraus. Die Untersuchung der fachlichen Anforderungen wird am Beispiel von Wohnhäusern in Stahlbauweise geführt. N2 - Models form the basis of the planning. They represent the characteristics necessary for the processing of a building in a form suited to the specific task. Between the different models, which are used for the representation of the building, there exist engineer-technical interrelations with regard to the illustrated aspects. At present these dependences are taken into consideration in the practical planning on basis of empirical values, normative guidelines and simplifying assumptions. The more detailed modelling of the building characteristics leads to a more defined linkage of the different models. To avoid an engineering island formation, there is an accordingly adapted representation of the relations existing between the single models necessary. With the rising demands on the processing of engineering tasks a data-technical representation wins in importance which realises more than a supply of selected information about the building and the support of a data exchange between different planners. This requires a discussion of the requirements for such a description from an engineer-technical view. The investigation of these technical requirements is carried out by the example of residential buildings in steel construction method.
