Spong3d: 3D printed facade system enabling movable fluid heat storage

Spong3D is an adaptive 3D printed facade system that integrates multiple functions to optimize thermal performances according to the different environmental conditions throughout the year. The proposed system incorporates air cavities to provide thermal insulation and a movable liquid (water plus additives) to provide heat storage where and whenever needed. The air cavities have various dimensions and are located in the inner part of the system. The movable liquid provides heat storage as it flows through channels located along the outer surfaces of the system (on the indoor and outdoor faces of the façade). Together, the composition of the channels and the cavities form a complex structure, integrating multiple functions into a singular component, which can only be produced by using an Additive Manufacturing (AM; like 3D printing) technology

Network of social functions and social housing for students in Neapolis Exarchia

Η περιοχή μελέτης την οποία επέλεξα να ασχοληθώ ειδικότερα βρίσκεται στο διάσελο μεταξύ του λόφου του Στρέφη και του Λυκαβηττού και εντάσετται μέσα σε ένα παραλληλόγραμμο που διαγράφουν οι οδοί Σόλωνος-Χαριλάου Τρικούπη –Ασκληπιού και Βουλγαροκτόνου και ονομάζεται καταχρηστικά Νεάπολη Εξαρχείων.Η οπτική από την οποία εξετάζω την περιοχή σκοπό έχει να προσδιορίσει την ταυτότητα της και να εντοπιστούν τα προβλήματα και οι ανάγκες των κατοίκων της στην σημερινή εποχή.Αποτέλεσμα της ανάγνωσης του τόπου είναι ότι πρόκειται για μια σύνθεση ετερόκλιτων εικόνων που περιλαμβάνει διαφορετικές ομάδες πληθυσμού ,δείγματα της αστικής αρχιτεκτονικής από όλες τις χρονικές περιόδους και χρήσεις γής που εναλλάσονται κατά τόπους.Το κυριο πρόβλημα που εντοπίζω στην περιοχή είναι η μεγάλη πυκνότητα κλειστών επιχειρήσεων.Ορμώμενη από αυτό το πρόβλημα και από μία μελέτη του δήμου Αθηναίων του 1993 για την περιοχή επιλέγω να επιλύσω το πρόβλημα της έλλειψης κοινωνικών υποδομών στην περιοχή οργανώνοντας ένα δίκτυο με άξονα την οδό Μαυρομιχάλη.Το δίκτυο αποτελείται από κλειστά ισόγεια τα οποία οργανώνονται σε τρείς πόλους σύμφωνα με την ηλικιακή ομάδα νέοι- παιδιά-ηλικιωμένοι και τοποθετούνται ανάλογες χρήσεις σε αυτά.Διαλέγω να επιλύσω σε μεγαλύτερη κλίμακα την κοινωνική κατοικία για φοιτητές στην θέση του υπαίθρίου parking στην συμβολή των οδών Διδότου και Μαυρομιχάλη.Η πρόταση μου για την κοινωνική κατοικία στήριζεται στο δίπολο μικρές μονάδες-δωμάτια για τον ιδιωτικό χώρο των φοιτητών και στον κοινοχρηστο χώρο που αποτελείται από υπαίθριους και κλειστούς χώρους.The area I chose to make my research exists between Strefis hill and Lycabetous and is included in a square which is formed from the streets Solwnos-Charilaou Trikoupi-Asklipiou-Voulgaroktonou and is named Neapolis Exarchiwn.The view that I am considering the area has aims to find the identity of the area and the nowadays problems of the citizens.As a result it came that it is a composition of different pictures which include different population groups and urban architecture from each period and land uses that change from place to place.The main issue which I locate in the area is the hight density of closed business.Being motivated by this problem and a research of Athens municipal in 1993 for the area I choose to look at the lack of social infrastructure by organizing a network with main axis Mavromichali street.According to the age of population children-youngsters-elderly aged similar uses being placed.i choose to consider in a larger scale social housing for students in the crossroads of the streets Didotou –Mavromichali street.My proposal for social housing is based on two poles the private space for the students..which is being translated in small units of living and outdoor and indoor communal spaces.Μαρία Βαλεντίνη Σαρακινιώτ

Development and prototyping of an integrated 3D-printed façade for thermal regulation in complex geometries

\u3cp\u3eCurrently, several research projects investigate Additive Manufacturing (AM) technology as a possible construction method for future buildings. AM methods have some advantages over other production processes, such as great freedom of form, shape complexity, scale, and material use. These characteristics are relevant for façade applications, which demand the integration of several functions. Given the established capacity of AM to generate complex geometries, most existing research focuses on mechanical material properties and mainly in relation to the load-bearing capacity and the construction system. The integration of additional aspects is often achieved with post processing and the use of multiple materials. Research is needed to investigate properties for insulation, thermal storage, and energy harvesting, combined in one component and one production technology. To this end. the research project SPONG3D' aimed at developing a 3D-printed façade panel that integrates insulating properties with heat storage in a complex, mono-material geometry. This paper gives an overview of the panel development process, including aspects of material selection, printing process, structural properties, energy performance, and thermal heat storage. The development process was guided by experiments and simulations and resulted in the design and manufacturing of a full-scale façade element prototype using FDM printing with PETG. The project proved the possibility of the integration of functions in 3D-printed façades, but also highlighted the limitations and the need for further developments.\u3c/p\u3
