On the Fundamental Period of Infilled RC Buildings
2015
This paper investigates the fundamental period of vibration of RC buildings by means of finite element macro-modelling and modal eigenvalue analysis. As a base study, a number of 14-storey RC buildings have been considered \"according to code designed\" and \"according to code non-designed\". Several parameters have been studied including the number of spans; the span length in the direction of motion; the stiffness of the infills; the percentage openings of the infills and; the location of the soft storeys. The computed values of the fundamental period are compared against those obtained from seismic code and equations proposed by various researchers in the literature. From the analysis of…
The redesign of an Italian building to reach net zero energy performances: A case study of the SHC Task 40 - ECBCS Annex 52
2011
In the framework of international actions to reduce the energy requirements and greenhouse gases emissions due to buildings, a new International Energy Agency task has been recently established in order to study Net Zero Energy Buildings (NZEBs). The commonly shared concept of NZEB, is a building whose annual balance of energy consumptions tends to zero. This concept is still too imprecise and the authors of this paper participate to the activities of SubTask B of IEA Task40 with the aim of establishing an internationally agreed understanding on NZEBs. The task is based on a common methodology for identifying and refining design approaches and tools to support industry adoption of innovativ…
Public wash-houses in Portugal: spaces of aggregation and sanitary aid. The case of study of the city of Aveiro
2019
This paper investigates the typology of the Portuguese public wash-houses that represents a very important sanitary aid and a space of social aggregation. More particularly, the most common features of such a typology will be outlined: architectural configuration, materials and technology, constructive characteristics, hydraulic equipment, historical evolution. These simple but highly functional little buildings are spread across the whole country and had been extremely important for the population since the middle age. In the last two centuries, new wash-houses were built, also following the scientific advances and the novel health requirements that spread in Europe between the XIX and XX …
The uncertainty of the energy demand in existing mediterranean urban blocks
2013
The objective of the paper is to describe a stochastic model that has been developed to obtain load profiles for household electricity. For the study, several profiles have been generated in order to simulate the electrical demand of a residential building block or neighbourhood and evaluate the uncertainty of its energy use. The paper is divided in three different parts: development of the model, validation and determination of the uncertainty demand. In the first parts the basis of the model and how it works is explained. The second one represents the validation of the model, the input data and its results. The last step is focused on a statistical analysis of the electricity demand of a …
The efficiency of the incentives for the public buildings’ energy retrofit. The case of the Italian Regions of the “Objective Convergence”
2017
Gli obiettivi di riduzione del consumo energetico e delle emissioni di gas serra, enunciati in molte Direttive europee, hanno posto in risalto la necessità di promuovere interventi di miglioramento dell’efficienza energetica del patrimonio edilizio esistente. Le amministrazioni locali, in particolare, dovrebbero assumersi la responsabilità di diffondere la cultura ambientale anche effettuando interventi di retrofit negli edifici pubblici di loro proprietà, sulla base di diagnosi energetiche degli edifici, di proposte progettuali e di verifiche del raggiungimento della convenienza finanziaria, che può essere agevolata dall’erogazione di incentivi. L’Unione Province d’Italia (UPI) nel 2013, n…
Basic assumptions for introducing circular solutions in the buildings sector
2016
Tradycyjne, linearne modele biznesowe są jedną z głównych przyczyn braku zrównoważonego rozwoju, nadmiernego wykorzystywania zasobów nieodnawialnych i energii, a także nadmiernego wytwarzania odpadów. Odpowiedź na te problemy stanowi koncepcja gospodarki o obiegu zamkniętym, której celem jest poprawa wydajności w gospodarowaniu zasobami i energią w każdej fazie cyklu życia produktu (usługi). Głównym celem niniejszego artykułu jest określenie, co może być uznawane w sektorze budownictwa za produkt w ramach gospodarki o obiegu zamkniętym, a także, jakie rodzaje takich produktów i / lub usług mogłyby być potencjalnie wykorzystane przez firmy doradcze funkcjonujące między innymi w sektorze budo…
High-rise timber architecture: an opportunity for the sustainability of the built environment
2019
Bioeconomy, circular economy, land use reduction, sustainable use of natural resources, reduction of CO2 emissions in the atmosphere and recycling are the keywords which the building world must face in the near future, as the environmental emergency can no longer be postponed. In order to disseminate in the scientific community the different possibilities of timber as a sustainable building material throughout its whole life cycle and to provide the professionals with suitable decision-making tools for a conscious design, within the cultural and scientific scenario of the recent years, the paper serves as a moment of reflection highlighting how a closer integration between different sectors…
Dentro una ricerca
2014
Saggio di introduzione alla monografia "PALERMO NORD" di Isabella Fera, sulla ricerca in corso intorno alla città dell'espansione a Nord di Palermo, a partire dall'ipotesi di considerare la grande quantità di costruito in questa area come un "patrimonio" privato e collettivo, degno di una nuova attenzione anche per le sue qualità odierne inaspettate e con lo sguardo rivolto alle sue straordinarie potenzialità di trasformazione.
Optimization of trigeneration systems by Mathematical Programming: influence of plant scheme and boundary conditions
2014
The large potential for energy saving by cogeneration and trigeneration in the building sector is scarcely exploited due to a number of obstacles in making the investment attractive. The analyst often encounters difficulties in identifying optimal design and operation strategies, since a number of factors, either endogenous (i.e. related with the energy load profiles) and exogenous (i.e. related with external conditions like energy prices and support mechanisms), influence the economic viability. In this paper a decision tool is presented, that simultaneously optimizes the plant lay-out, the sizes of the main components and their operation strategy. For a specific building in the hotel sect…
DAS PHÄNOMEN Maifinito. DEN PATIENTEN WIEDERBELEBEN: REANIMATION UND AGENCY Gaetano Licata im Gespräch mit Arno Brandlhuber
2016
