The study examines the existing technical basis in building practice for the application of cyber-physical systems on the façade. The associated intelligent cooperation of automated adaptive façade functions, inspired by intelligent technical systems in industry 4.0, offers a potential for the overall building performance. By the type and scope of automations already introduced today, façade functions are identified that offer special potential for consideration in a cyber-physically implemented façade. The investigation represents a multiple case study analysis in which office façades in Germany are examined. Data is collected from literature, expert interviews and field investigations. The evaluation is carried out in a single case analysis and a following cross-case analysis, in which patterns and dependencies in the joint implementation of automated and adaptive façade functions are identified. The study found that especially sun-related functions are implemented adaptively, often in combination with ventilation and the heating and cooling support function.
The high and increasing requirements concerning energy consumption and the interior comfort of buildings result in a demand for more efficient façade constructions. In its role as a mediator between the exterior and interior of a building, the façade takes on a multitude of functions with effect on the building's performance. Intelligent façades offer higher performances compared to static constructions, achieved by dynamic adjustments to changing environmental influences and interior requirements. Such systems are being explored and already applied. The concept of intelligent façades exists since the beginning of the 1980s. Since then, the technological possibilities for the implementation of intelligent systems have multiplied. Today, the fourth industrial revolution is based on the implementation of intelligent and networked production facilities. Considering the current exploration of intelligent technical systems in the industry, the understanding and the demands on the intelligence of a system change. The aim of this study is to examine the comprehension of an intelligent system in the context of the façade and in the context of the industry. This is to provide the basis for subsequent research on the transferability of strategies. The study provides used terms, relevant aspects, current definitions and characteristics of the respective intelligent system.
The paper discusses a case study for a seating element that takes into account human factors as well as aspects of structural performance, material properties and production parameters within an integrative design approach. Generico is a prototype for a new way of design thinking, developed with a holistic approach. The design is based on the requirements of comfortable sitting and responds to load forces and ergonomic conditions. The Generico chair -resulting from an all-embracing line of thought, from design to production, is an ideal field of application for 3D-printing-technology as it allows for an optimal material distribution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
