Suitable building materials can help mitigate these effects. To investigate this, a simulation study was conducted to test the influence of different roof coverings, materials for outer surfaces (ground) and green infrastructure (GI) on the microclimate. The analysis comprises the simulation of 38 data sets for roofs, ground materials and GI in dry and moist conditions in a microclimatic model using ENVI-met. The results for the whole neighborhood show that choosing light-colored ground materials reduces the dry bulb temperature (DBT) at the same height by up to 0.4 K and has a positive effect on the urban microclimate. However, reflective surfaces can have a negative effect on the thermal comfort of the pedestrians as the physiological equivalent temperature (PET) is 1.0 K higher above bright surfaces. This is due to reflected short-wave radiation, which significantly increases the perceived heat stress despite lower air temperatures. During daytime without shade the PET is up to 2.6 K higher at a height of 1.7 m above ground with a dry GI compared to a moist GI.","PeriodicalId":55397,"journal":{"name":"Bauphysik","volume":"47 4","pages":"247-260"},"PeriodicalIF":0.3,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They help to regulate building temperatures by storing excess heat when it is too warm and releasing it again when it gets cooler. This leads to a more even and comfortable indoor climate and reduces dependence on conventional heating and cooling systems. In connection with the challenges of climate change, PCMs are becoming increasingly important. The development of a process to specifically increase the heat storage capacity of load-bearing concrete components was funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK) as a ZIM cooperation project (PCMZ). The aim was to partially optimize the storage capacity of a concrete component by spatially enriching it with PCM particles, as an evenly distributed enrichment leads to considerable losses in the strength of the concrete. The production of these multifunctional components should therefore be carried out using additive manufacturing processes. The gain in storage capacity on the one hand and the loss in strength on the other were investigated as part of the project.","PeriodicalId":55397,"journal":{"name":"Bauphysik","volume":"47 4","pages":"261-270"},"PeriodicalIF":0.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical behavior of components made of composite cross-sections essentially depends on the material properties of the components used and on their interaction in the composite. When using very thin steel profiles, the activation of the cladding in the composite cross-section is of crucial significance. To meet serviceability criteria under static loads, the effective stiffness of the yielding composite is decisive. The determination of the effective stiffness requires knowledge of the modulus of displacement of the connection. The aim was to determine and evaluate the mechanical behavior under varying moisture levels. It was shown that the method of composite cross-sections with yielding mechanical bond can also be used for very thin steel profiles with gypsum board cladding and screw connections, that the use of climate-dependent displacement moduli leads to good consistency and that a realistic, mathematical determination of the load-deformation behavior of lightweight stud partitions from the initial stiffness to the quasi-elastic range is possible.","PeriodicalId":55397,"journal":{"name":"Bauphysik","volume":"47 4","pages":"271-277"},"PeriodicalIF":0.3,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
