Involucri evoluti a comportamento dinamico: tecnologie e modelli applicativi nel contesto geografico, normativo e imprenditoriale della Regione Emilia-Romagna
Abstract
Introduction The importance of connection between construction envelopes and environmental and technological systems is rising up thanks to the grow request to answer to environmental necessities and resources safe. Moreover the envelopes become a complex technologic machine, which are able to adjust automatically to environmental condition and weather changes. Facing these technical problems, architects must plan more flexible and active evolved envelopes with dynamic behaviour to adapt to the sudden changes of surrounding condition. The principal problems are in particular the aspects related to the correct material choice and the study of physical and thermal principles of the envelope. Every envelope is constituted of an external skin, an internal one and an air space buffer in the middle. According to the type of material we could discern between transparent, translucent and opaque envelope, everyone with specific characteristics. The study refers in particular to the glassy-glassy envelope (made of a double glass skin), which is the principal field of research of our group. Aims The principal aim is to determine new universal application model, solution and use possibilities of glassy-glassy envelopes, studying the best and useful technical and physic parameters to improve the energy safe and environmental performance quality. Step by step the middle aims were: • Evolved envelope state of art definition; • The critical analysis of lacking and mistakes about actual knowledge on evolved envelope; • The study of material and component basing on previous analysis and current courses; • Definition of instruments able to solve technical aspects and problems; • Collection and schedules of existing projects; • Application models of dynamic evolved envelope Limits Because the verification of normative applicability was easier in a regional contest than in an international one, the methodologies pointed out by this research concern only a regional background, even if the research was based on national and international quality projects, Generic considerations about evolved envelopes are missed out. A more specific parameters dissertation was preferred to define physic phenomena limitation and application solutions. Moreover the research concern only glassy-glassy enveloped, a field that permits a deeper tractability starting from the experience of Professor Fabio Conato and his collaborators (Arch Simona Cinti and Arch Giuseppe Camillo Santangelo) and from the elaboration of data collected about the construction of double skin envelope. Methods The results are based on a bibliographic revision of the literature and on a collection of expert opinion in the branch of envelope (planners, technicians and producers). Project phases: • Architectural characteristics and performances analysis of the evolved envelops. Definition of functional principles; • Technical assay about the possibilities of envelope applications: • Examination of energy safe plans already existing; • Identification and consequences of application of existing normative and rules about quality environmental assessment and energy safe certification (both in UE, Italy and Emilia Romagna institution); • Revision of documents concerning the need of dynamic envelope and quality verification instruments The research is based on theoretical physic principles connecting the environment to the buildings, on the evaluation of environment phenomena on a realized construction, on the possibilities to manage energy natural fluxes, on building thermal balance and on technical components exploiting renewable sources to produce energy. Results The final results confirm the validity of dynamic evolved envelope to rise good and variable performance. Otherwise the dynamic technology is efficient in a restricted area and is necessary the application of different typology of the same system to optimize performances. The analysis of this model of envelope is important to define the interventional scenario and the application system. The review of previous study also permits to analyze and rebuild prior hypothesis, particularly specifying the state of art relating envelope project and the lack of information, filling with new details. Consequently possibilities of envelopes solutions, internal and external factors and physic phenomena were defined. According to the ongoing normative, new planning indications and issues of normative elaboration were furnished. Finally, thanks to a new quick and concrete instrument (planning guide), the final results of such a complex field could be easy comprehensible. Recipient, development and future evolution This research would be finalized to society and people who work in building trade field, in order to help them in planning. Moreover the evaluation about the actual normative should bring new elements to discuss and formulate again this instrument. Also technical evolution and innovation in double skin envelope, nowadays lacking and inaccurate, could help the project of new advanced component solution. At the real end the research could show many solution apt to offer new evolved system Particularly: • Material: research in new material, production methods and components for wall face have a great importance to improve performance and characteristic of envelope; • Components: in particular one of the principal criticism about the space between the two skin of the envelope; • System: the grow request of performing wall face could transform the static system in a sort of dynamic system integrating both the wall and the air conditioning/healing system guarantying a thermal and visual comfort both in term of energy earn and use; • Actual building integration: the use of envelope in re-qualifying and renovate old buildings could be an interesting field of research; • Planner guide: this software is based on Emilia Romagna weather conditions. An implementation to other Italian and Europe reason should be necessary.
