Due to the demographic development and the continued rise of the living standard in many countries, global construction activity has seen an incessant increase during the past four years. The building sector accounts for more than 50% of the resource consumption worldwide – every second more than 1,000t of building material is used – and for close to 40% of the global greenhouse gas emissions. To tap this potential for achieving the political goals with respect to climate change (e.g. Paris Climate Agreement), significant changes concerning construction, operation, and demolition of the built environment must be made. From the very beginning, the CRC 1244 has been guided by the principle “build more with less – emission-free!” and consistently following this goal is now more important than ever.The CRC’s second funding period builds upon the results of the first, which was dedicated towards laying the foundations and identify-ing the potentials and implications of adaptive technology for and within the built environment.In the past four years, the ability to save enormous amounts of material, energy, and emissions by using adaptive structures was demonstrated. The hypothesis that new design approaches and methods are necessary for building adaptive hulls and structures was also confirmed. Special attention was therefore given to the development of these methods, which led to the need for architectural concepts to be reformulated holistically. For reformulating the underlying planning process, the interdisciplinary cooperation of all partic-ipating researchers was essential.For the upcoming funding period, all developed methods will be generalized. The focus shifts from simple sample problems, such as the 36m-high demonstrator-building, towards other types of structures. Despite the large potential for reducing resource consumption by adaptation of conventional structures, structures designed “adaptively” from the beginning can realize an even higher reduction in resource consumption and emission. Finding and characterizing these optimal typologies and topologies is a focus of the second fund-ing period.A large amount of additional savings in material consumption can be realized for two-dimensional elements and structures, which make up a significant portion of the total mass in many buildings. Therefore, the already developed form-finding and design methods will be extended for two-dimensional elements and structures and appropriate actuation principles need to be found. Adaptive facades be-come more important in the CRC’s second funding period as well. Building upon the foundation of the past four years, research on active facades for room conditioning will intensify, where the focus is on transitioning to renewable energy sources. The CRC’s re-search will answer questions regarding the design and dimensioning of the elements and develop strategies for operation that incorpo-rate additional short-term and long-term storage capacities and gua
