The physiological and cognitive effects of environmental stimuli from the built environment on humans have been studied for more than a century, over short time frames in terms of comfort, and over long-time frames in terms of health and wellbeing. The strong interdependence of objective and subjective factors in these fields of study has traditionally involved the necessity to rely on a number of qualitative sources of information, as self-report variables, which however, raise criticisms concerning their reliability and precision. Recent advancements in sensing technology and data processing methodologies have strongly contributed towards a renewed interest in biometric data as a potential high-precision tool to study the physiological effects of selected stimuli on humans using more objective and real-time measures. Within this context, this review reports on a broader spectrum of available and advanced biosensing techniques used in the fields of building engineering, human physiology, neurology, and psychology. The interaction and interdependence between (i) indoor environmental parameters and (ii) biosignals identifying human physiological response to the environmental stressors are systematically explored. Online databases ScienceDirect, Scopus, MDPI and ResearchGate were scanned to gather all relevant publications in the last 20 years, identifying and listing tools and methods of biometric data collection, assessing the potentials and drawbacks of the most relevant techniques. The review aims to support the introduction of biomedical signals as a tool for understanding the physiological aspects of indoor comfort in the view of achieving an improved balance between human resilience and building resilience, addressing human indoor health as well as energetic and environmental building performance.

Adaptive Building Technologies have opened up a growing field of architectural research aimed at improving the overall building performance, ensuring comfort while reducing operational energy consumption. Focusing on flexibility over short timeframes, these new technologies are however rarely designed within the broader frame of sustainability over their entire lifecycle. How sustainable these zero energy technologies really are is yet to be established. The purpose of the research is to develop a flexible easy-to-use Life Cycle Assessment (LCA) tool to support creative innovation and sustainable design choices in the early concept and design stages of Adaptive Building Technologies. This paper reports on the results of the first step of the research, providing a mapping in terms of structure and contents of the parameters involved in the design of these technologies. Addressed from a holistic point of view, the elements of the system were defined though a qualitative approach: relevant parameters were collected through document analysis, reviewing the state-of-the-art technology through online databases as ScienceDirect, Scopus, MDPI, ResearchGate, and organized according to hierarchy and relevance in the different life cycle stages. As a result, the paper identifies (1) relevant parameters defining the design of Adaptive Building Technologies; (2) materials, processes and concepts specific to the design of these technologies, as compared to conventional building technologies; (3) issues and knowledge gaps to enable successive research phases; (4) specific actions in each life cycle stage for designers and producers to optimize the design of the technology. The mapping graphically and hierarchically organizes the elements of the system within a flexible structure to be implemented and integrated over time, as the technology evolves, to support parametric design and enable alternative design concepts to arise within a cradle-to-cradle perspective.

The introduction of green plants in indoor spaces has raised a great amount of interest motivated by plants’ supposed capacity to improve the quality of indoor built environments. Subsequent studies have covered a broad range of topics, testing plants in indoor environments for their climate-mitigating effects, acoustic benefits, potential energy savings and the enhancement of the indoor microbial communities. Despite the diversity of focus in these studies, no major breakthroughs have been made involving the use of plants in indoor environments after nearly thirty years of research. To identify major inconsistencies and gaps in the research, this review, of an explorative nature, presents an analysis of plant-related parameters reported in 31 cases of experimental research involving the use of plants in indoor environments. The papers were identified by searching the online databases Google Scholar, ResearchGate, Scopus and MDPI and were selected based on their relevance to the topic and diversity of focus. Two classifications in table form provide an overview of the 38 plant-related parameters used in the reviewed research. The conclusions drawn from the analysis of the tables highlight a strongly anthropocentric frame of reference across the majority of the studies, which prioritize human and experimental convenience above plant physiology, and display an overall scarcity and inconsistency in the plant-related parameters reported.

The history of membranes is one of adaptation, from the development in living organisms to man-made versions, with a great variety of uses in temporary design: clothing, building, packaging, etc. Being versatile and simple to integrate, membranes have a strong sustainability potential, through an essential use of material resources and multifunctional design, representing one of the purest cases where "design follows function." The introduction of new engineered materials and techniques, combined with a growing interest for Nature-inspired technologies are progressively merging man-made artifacts and biological processes with a high potential for innovation. This chapter introduces, through a number of examples, the broad variety of hybrid membranes in the contest of experimental Design, Art and Architecture, categorized following two different stages of biology-inspired approach with the aim of identifying potential developments. Biomimicry, is founded on the adoption of practices from nature in architecture though imitation: solutions are observed on a morphological, structural or procedural level and copied to design everything from nanoscale materials to building technologies. Synthetic biology relies on hybrid procedures mixing natural and synthetic materials and processes.
