Contemporary Envelope Requalification: Innovation and Smart Technology for a New Approach to the Built Environment Katia Gasparini

Within the series of seminars and workshops the case study on company Ancap offered a field of research and application ideal for students on the issue of valorization of the built environment, using new technologies coming out from the contemporary research and experimentations. The case study has grouped many issues to deal with, in terms of design, construction, technology, and especially the environment. The demands of the property were related to some specific points, first of all the requalification of the factory envelope, because at this time appears as an anonymous warehouse in reinforced concrete. This was the main theme, which brings together two different approaches: the envelope requalification and his valorization, which, according to business demands, require a greater company visibility and identity in terms of both perception and communication. The second issue concerns the landscape in which the company is located. The factory covers a production area of 20,000 square meters, employing about 170 professionals. Set in a hilly, d’Ancap is located in close proximity to the railway line that connects Venice to Milan. On the opposite side, to the south, there is a road that runs along the A4 motorway and that leads to the three neighboring municipalities: Sommacampagna, Sona and Castelnuovo del Garda. A dozen miles away is located the Verona airport, Valerio Catullo. The construction, therefore, is not found as usually

happens in an industrial area, but in hilly area. It’s the only company in the area, located on the border railway between two hills and clearly visible from the top of them. The factory is perceptible from aircrafts taking off and landing from Verona, from the railway trains in transit to and from Milan. It should be noted that the company is one of the few still with railway crossing within the territory of the company, used in the past for freight transport and for which the company still owns the rights. Having that construction and location conditions, it was required to design a new architectural shell, communicative, which returns company visibility even commercial terms, integrating the building into the hill context using color and light technologies. The project should include an over cladding system, temporary or mobile, but structurally independent from the original structure. Were not provided limits on technologies and materials use, but the students were advised to use innovative technologies and possibly “smart” in order to meet the requirements related to energy saving and landscape non-invasive. The first line of action, to solve the energy problem, is very much felt by the business property because the production requirements need considerable energy expenditure. So where possible was required to use technologies allowing the full energy independence, and possibly an “Energy plus” envelope-type, in order to

compensate the company energy needs, without thereby interfering with the environmental quality. Another company request was to design an anti dust and acoustic barrier facing the railway, to limit the trains passage interference on the north elevation. Description of the existing structure The building is 300 m long., wide 60 m., was created in 1964, having two later expansions. The supporting structure

is made of reinforced concrete columns (40x40 cm) on which were applied infill concrete panels (20 cm thick). The latter have a different grid dimension resulting from the three different interventions (5 m., 1.5 m., And 2.5 m.). The roof is of three different types: the first part has a vaulted roof, the second and third vertical and horizontal shed. The windows change according to the system of modular panels: the first part, in which are located the offices, is characterized by continuous windows screens by metal shading devices,

the second is equipped with not opening windows (1 x 2.25 m.), the third is made by fixtures, inwardly openable ribbon windows. On the north elevation, for the first 145 meters, was placed a sheet metal canopy to protect the waste material. The entire complex has a maximum height of 6 meters. Analysis of the objectives and contextualization technologies The project’s objectives are four: - Draft rehabilitation with a new envelope having communication purposes - Requalification of energy plant - Valorization of the environment and countryside - Barrier on north side In essence, the project brings together three key concepts in architecture: requalification, valorization and reduction of energy consumption. A draft “UPGRADING” assumes that the comparison between the needs expressed by users and performance to be understood as quality building offers, require not significant adjustments. The requalification project objective, in the light of the results of analytical tasks, will be to define the step of performance in relation to the new needs expressed by users and work programs necessary to improve the building or its components performance identifying appropriate solutions effectively responding to the requirements1. Any recovery, requalification, valorization and management action2 produce effects on the surrounding, whether natural or man-made. These effects induce a qualitative change on buildings, on the roads accessibility and continuity of the ecosystem, as well as on the perception and use of the same places. The concept of “exploitation” of the environmental and cultural heritage

is enshrined both in the Italian Constitution (Article 9)3 as in the Code of Cultural Heritage and Landscape4. The same article states that the valorization includes educational goals of close links with the heritage, in order to improve the knowledge and conservation of cultural and environmental assets, increasing the usability. The landscape valorization of protected areas concerns as much as requalification of buildings and areas under protection, same as (especially, in this case) the creation of new landscape values5. The valorization then may be made through operations of highlighting all the parameters relevant to an area, to one or more buildings, to a process, with the aim of encouraging and highlight some aspects that are considered virtuous. In the specific case of a building requalification the “valorization” refers to all those activities of promotion and support the requalification and preservation of existing buildings ensuring the best conditions for the use and exploitation. The maintenance and preservation of existing buildings also rely on meanings that go beyond their utility and act as cultural, educational and ethical topics able to stimulate a new awareness of environmental protection6. The intervention recommended for students was the design of an over-cladding system. The system has been tested by me in previous research, classifying and analyzing numerous case histories on which they were made refurbishing or building new architectural envelopes. In particular, the classification of requalification and regeneration of the building facades was inferred from researches recently completed and in the way to be published on the topic of requalification of the building envelope within the PRIN 20087. The term over-cladding identifies the process according to which the previous coating is left and used as the

basis for the new one. Is carried out in the presence of redevelopment of existing buildings project and can serve to protect the existing facade in such a way that the building has regenerated the same life expectancy comparable to that of a new one. A classic example, often offered to the students and well-known in this field, is the intervention of over-cladding designed by UNStudio on HallWest Gallery in Korea. Even then it was to make works of requalification on an industrial building with precast concrete system, converted into commercial building, a shopping mall . In this project they installed a metal frame to support a coating of dichroic glass cladding backlit with a RGB LED electronically controlled. This intervention was aimed prominently for building perception and visibility, both day and night. In the realization of a new envelope having the purpose of communication the appearance performance becomes leading. In this case it is useful and necessary for students to a study the overcladding components and materials used same as the perceptual system intervention in relation to the environment. Based on the research even mentioned (Prin 2008 and others), the analysis of the perceptual system can be performed by a classification of the surface pattern. The analysis of the perceptual system allows the decomposition of architectural surface from the point of view of the drawing, of the regularities found within a set of observed objects (pattern) and the techniques used to grasp the visibility of the facade (technologies). Specifically, the pattern identifies a repetition of a geometric graphic pattern on a surface, so much so that by examining “the object in all its parts, will establish the skeleton structural and relationships of the various parts with the whole”. In the study of the perceptual system the selection of appropriate technologies used to emphasize the perception of the pattern of the façade is essential. The technologies are

distinguished according to monochrome or polychrome colors, typical of glassy materials, plastic and metal. In certain cases it’s the material itself that defines the color of the facade, in others, the applied films, paints or dyes to obtain different tones and saturations. Completely different is the perception given by lighting technologies. In this case, in fact, the perceptual system is characterized by the use of lamps and / or LEDs. These are managed by computer systems allowing you to give more dynamism to the building and expand the color combinations available. The mixed technologies, finally, make use of both the color than light. In this category we can find electronic technologies often used in the construction of media facades, screens or interactive displays, materials and systems, “smart” technologies now often employed on energy consumption reduction. The choice of a technology over another depends not only on the design target and the available budget, but also paying attention to the environment impact. There are three types of relapse: a. environmental, when the intervention upgrades the building from the standpoint of energy and insertion in the context (aspect); b. social-communicative, when intervention, as well as a technology upgrade or plant combines a surface action for the purpose of communication integrating pattern color and light technologies; c. economical, if the goal of reducing energy consumption and maintenance with interventions is focused to a technological upgrade for an overall building requalification. As the architectural shell evolved from the point of view of communicative interaction with the environment through

the use of new technologies, so it was also with regard to the energy interaction. Today the building envelope is no longer just a protective physical barrier, but may be able to actively adjust the flow of light energy and thermal energy, as well as to generate electricity and usable heat for the “metabolism” of buildings8. In fact, it can serve as protection and closure of the interior from the exterior and changing situations, a “filter to select external welcome aspects from those unwelcome”, recreating indoor “an autonomous micro-environment thanks to mechanical systems and artificial plants”9. Currently, therefore, the cladding system is required to erform multiple functions in the same time. Convey information and modulate the relationship with the visual perceptual surrounding. Regulate the energy flow between the inside and the outside of the building. Respond to performance requirements of environmental control, primarily related to heat transfer, lighting and natural ventilation, sound and vapor transmission. Protect from rain and intrusion, from electromagnetic phenomena and to become ’active’ capturing renewable energy10. The temperature regulation systems, sometimes coincident with those of media, may be both static and dynamic, and, in the latter case, can be automated by electronic control, or may comprise of special materials, so-called smart materials, capable of responding to changes in external environmental conditions changing in some properties (smart materials property-changing) or by returning the energy stored in an easily usable (smart materials energy exchanging)11. For example, it can be easily obtained dynamic self-regulating solar screening capable of generating energy, mostly thanks to the integration of photovoltaic modules12. So contemporary architectural envelope tend to not be recognized as a “wall”, closed, protective and massive, able to

clearly divide the interior from the outside, as in the past. Today, the surface that bounds seems to be rather a selectively permeable filter towards the flow of information, matter and energy, “as a membrane having interface function”13.
