From the Paper to the Tablet: On the Design of an AR-Based Tool for the Inspection of Pre-Fab Buildings. Preliminary Results of the SIRAE Project
2018
Energy-efficient Buildings (EeB) are demanded in today’s constructions, fulfilling the requirements for green cities. Pre-fab buildings, which are modularly fully-built in factories, are a good example of this. Although this kind of building is quite new, the in situ inspection is documented using traditional tools, mainly based on paper annotations. Thus, the inspection process is not taking advantage of new technologies. In this paper, we present the preliminary results of the SIRAE project that aims to provide an Augmented Reality (AR) tool that can seamlessly aid in the regular processes of pre-fab building inspections to detect and eliminate the possible existing quality and ener…
Foster Carbon-Neutrality in the Built Environment: A Blockchain-Based Approach for the Energy Interaction Among Buildings
2022
Decarbonizing urban environments and reducing their energy consumption is one of modern society biggest commitments. In this regard, both the scientific community and international governments have been giving special consideration on improving the energy-environmental performance of mostly single buildings; recently the focus has been shifting towards a broader Positive Energy District (PED)/ Energy Community (EC) vision, from small clustered group of buildings to neighborhoods up until urban settlements. In this respect, integrating the use of renewable energy resources (RES) and actively involving building users can have a significant environmental impact on local areas. Within this fram…
A novel thermoeconomic analysis under dynamic operating conditions for space heating and cooling systems
2019
Abstract Thermoeconomic analysis allows for a deep understanding of the cost formation process within an energy system, providing insights into the possible routes for improvement. Several thermoeconomic approaches are well-established for application in systems with steady operating conditions, such as power plants, while a limited number of applications to air-conditioning systems in buildings have been proposed, due to the difficulties in dealing with very irregular load profiles and unsteady plant operating conditions. This study investigates the potential of Thermoeconomics as a support for decision making in building energy systems, proving its capability to identify trade-offs betwee…
Edilizia abusiva a Favara. Analisi dell’insediamento e sviluppo del territorio
2007
Il Piano Regolatore Generale, strumento di fondamentale importanza per lo sviluppo di un centro urbano e del suo territorio, è ancora per diverse città siciliane un obiettivo da raggiungere. I dati provenienti dall'Assessorato Regionale al Territorio e Ambiente (A.R.T.A.) indicano una Sicilia decisamente indietro nella progettazione urbanistica. Nell'isola soltanto il 40,3% dei comuni hanno un piano regolatore vigente. La mancata approvazione degli strumenti urbanistici ha influito negativamente sui processi di urbanizzazione, spesso frammentari e disorganici. Le città si sono sviluppate senza una forma, un modello riconoscibile, alimentando nei cittadini una politica che ha preferito l’edi…
Il comfort indoor nel patrimonio edilizio esistente. Tecnologie e metodi per gli ambienti di vita
2022
This volume is the result of wide-scope research on the application of IEQ (Indoor Environmental Quality) in existing buildings. The examined items are the evaluation methods and standards related to the environmental parameters for the well-being levels required to guarantee suitable livability in indoor environments. An analysis is provided on the state of the art of technological aspects in architecture for the achievement of salubrious and comfortable indoor spaces. The study is focused on passive systems for microclimatic control, with a re-proposition of the most ancient ones. Nowadays, when revisited, they have proven to be effective solutions, especially due to their possibility to …
RETROFITTING DETENTION BUILDINGS OF HISTORICAL-CULTURAL INTEREST. A CASE STUDY IN ITALY
2021
Penitentiary buildings in Italy include many buildings of undoubted historical and architectural importance. These have been, or will soon be, subject to structural changes necessary to adapt their spaces to the current regulations of prisons. The idea of punishment itself has changed over the centuries, so it is a physiological necessity to adapt existing buildings accordingly. When, however, such buildings date back centuries, they should not be considered a mere container but a historical testimony rich in meaning for the entire nation. The characteristics of the materials, distribution, and what these buildings have represented for the city should be the object of study and protection, …
Seismic evaluation of ordinary RC buildings retrofitted with externally bonded FRPs using a reliability-based approach
2020
International audience; Despite the extensive literature on reinforced concrete (RC) members retrofitted with fiberreinforced polymer (FRP) composites, few studies have employed a reliability-based approach to evaluate the seismic performance of RC buildings in terms of their collapse capacity and ductility. In this study, the performance of a poorly-confined RC building structure is investigated for different FRP retrofitting schemes using different configurations and combinations of wrapping and flange-bonded FRPs, as two well-established techniques. A nonlinear pushover analysis is then implemented with a computational reliability analysis based on Latin Hypercube Sampling (LHS) to deter…
Modeling and design of Net ZEBs as integrated energy systems
2015
Net-zero energy buildings (Net ZEBs) are emerging as a quantifiable design concept and a promising solution to minimizing the environmental impact of buildings. This is the main concept that is focused on this chapter with emphasis on dynamic modeling and examples of technological approaches to achieve net-zero energy. Appropriate modeling of building-integrated solar energy systems is essential for the design of Net ZEBs and the study of optimal control strategies. The net-zero energy balance may be achieved through a combination of passive and active solar technologies, heat pumps, combined heat and power, and energy efficiency measures to reduce energy consumption for lighting and applia…
Experimental and Numerical Analysis of Air Flow, Heat Transfer and Thermal Comfort in Buildings with Different Heating Systems
2016
Abstract Monitoring of temperature, humidity and air flow velocity is performed in 5 experimental buildings with the inner size of 3×3×3 m3 located in Riga, Latvia. The buildings are equipped with different heating systems, such as an air-air heat pump, air-water heat pump, capillary heating mat on the ceiling and electric heater. Numerical simulation of air flow and heat transfer by convection, conduction and radiation is carried out using OpenFOAM software and compared with experimental data. Results are analysed regarding the temperature and air flow distribution as well as thermal comfort.
Role of Sky-gardens in Improving Energy Performance of Tall Buildings
2018
Natural ventilation has been used as a passive strategy for many decades but only now its importance in tall buildings for addressing the issues of high energy usage and reducing carbon footprints is emerging. Sky-gardens can play an important role in successful implementation of natural ventilation through amplification of natural wind speeds. This study presents a state-of-the-art review on optimization of tall buildings energy performance through incorporation of sky-gardens. Pros and cons of use of natural ventilation for multi-story buildings are highlighted. Details of involved technical difficulties and barriers in the construction and operation process of sky-gardens are also given.…
