Strumenti di analisi per un approccio integrato alla progettazione residenziale in clima temperato
No full textThe research focuses on the analyses of multifamily houses, both new and refurbished ones, in the temperate climate. The objective of the work is to identify a multi-disciplinary energy approach for the residential sector, to provide concrete answers and an operational planning tool. The final instrument is called by the author LECTeC House Tool (Low Energy /Cost in Temperate Climate House) and it has the aim to became a necessary support to designers
Valutazione dell’influenza degli aspetti tipologici e tecnologici sull’efficienza energetica di un edificio residenziale in Italia
No full textCase a schiera a Stadel
No full textTre abitazioni sorgono a scalare nei loro rispettivi due piani, collegate da un livello comune adibito a garage. Il risparmio energetico e il controllo delle condizioni climatiche sono ottenuti attraverso la struttura massiva di calcestruzzo e l'installazione di un recuperatore di calore abbinato a un sistema di ventilazione meccanizzato. Rispetto della natura, rapporto con il luogo, uso dei materiali ecologici e sfruttamento di energie rinnovabili: questi sono i temi generatori del progetto. Gli architetti Luthi+Partner hanno costruito tre residenze partendo da una attenta lettura del contesto e le hanno rese armoniosamente partecipe del paese di Stadel nel Canton Zurigo
Resilient manufacturing systems enabled by AI support to AR equipped operator
Full text linkSupply chains and manufacturing systems robustness and resilience are, for many years, but especially nowadays, key features requested to ensure reliable and efficient production processes. Two domains are crucial to achieve such purpose: the former is fast and comprehensive monitoring, efficient and reliable condition detection and effective and explicable support for decision making. The latter refers to the intervention by operators, able to better identify problems and to put in place effective operations aimed at fixing it or, better, to prevent such circumstances. This paper presents an integrated approach encompassing a sophisticated IoT and AI-based approach to monitor and detect critical situations, fully integrated with an AR (Augmented Reality) system supporting operators in the field to take informed actions in bi-directional continuous connection. Activities in the context of EC funded project Qu4lity developed in Politecnico di Milano Industry 4.0 Lab, a test environment implementing the proposed approach and demonstrating in an automated production line the effectiveness of the approach, significantly improving performances. Analysis of performance indicators demonstrates the soundness of the proposed solution and implementation methodology to make the overall production process more resilient, efficient and with product defects reduction
Evolutionary housing process. Design tools for an integrated approach to urban, typological and technological issues for housing in the 21st Century
No full textChanging trends in lifestyles has direct impact on housing process. Architects of the future are faced with the challenges of domestic space needs of different people. There is need to design dwellings based on flexibility, adaptability, incorporating energy saving measures. Currently the housing process design involves the definition of the relationship between low energy comsuption and low CO2 emissions against a backdrop of emerging trends on new residential buildings. The research will be guided by following workpackages at different scale from urban to architectural and technological design. The findings of this study will show how the evolutionary housing process is connected to these three steps: context, typology and sustainable renovation, with the definition of best practice in design of “House for 21st Century”. That is compatible with the environment and meets the users’ needs
A sensitivity analysis approach: Simulation tools as support at the early stages of low energy housing design
No full textAssessing steel buildings circularity through the synergy of LCA and MFA
No full textThe transition of the building sector to a circular economy is thus of primordial importance to mitigate both problems. Material flow analysis (MFA) and life cycle assessment (LCA) are two of the most known and diffuse methodologies to quantify the environmental and economic impacts of the built environment through a circular approach. While there have been advancements over the last decade in the implementation of various circular strategies, the building industry urgently needs to implement more effective recycling and reuse procedures to lower the rate of consumption by applying a circular economy framework, overcoming barriers and limits, such as data quality and availability used in the assessment process. This paper provides a critical review on methodologies to evaluate circularity and sustainability for steel buildings and explores potential synergies between MFA and LCA to define a hybrid (MFA/LCA) methodology for the assessment of the circularity of buildings over the complete life cycle
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
