RECUPERO ENERGETICO DEGLI EDIFICI ATTRAVERSO CERTIFICAZIONE E QUALITÀ. Esempi di strumenti e misure in Europa.
No full textL’efficacia delle politiche mirate a incrementare e ottimizzare il recupero energetico del costruito e rassicurare proprietari e investitori verso migliori garanzie dell’investimento è oggi tra i principali obiettivi comunitari. Il volume illustra i risultati dell’indagine iniziale del progetto EIE REQUEST analizzando strumenti e tecniche volti ad accrescere la quantità e la qualità degli interventi di riqualificazione energetica degli edifici residenziali in Europa. Dei circa cento strumenti in uso in 27 diversi paesi, inerenti comunicazione, formazione e qualificazione, incentivi finanziari, partecipazione, sono approfonditi e riportati alcuni esempi significativi (Best Practices) distinti in: strumenti di promozione degli interventi di miglioramento raccomandati dal Certificato Energetico (ACE) degli edifici; meccanismi per garantire la qualità del recupero energetico in fase di fornitura ed esecuzione dei lavori. Il documento fornisce quindi alcune considerazioni conclusive circa l’analisi condotta e il ruolo delle Agenzie energetiche nazionali nel supportare autorità e decisori nella definizione, attuazione e monitoraggio degli strumenti, nell’orientare i programmi formativi e nella creazione di una rete costituita dai diversi attori del settore per implementare e disseminare gli strumenti, generando così l’impatto auspicato
Field Performance Evaluation of Air Quality Low-Cost Sensors Deployed in a Near-City Space-Airport
No full textAir pollution is a current problem for the environment and public health. Its impact needs to be monitored in urban agglomerates and critical hot spots such as airports. Green aviation with low air emissions is a sustainable goal for the future. The air pollutants are monitored by governmental agencies that employ regulatory monitoring stations, which are very accurate but also very expensive, bulky, and maintenance demands. On the contrary, low-cost sensor systems can offer a proper solution to cover large areas at high spatial-temporal resolution. However, the low-cost air quality sensors are less accurate than reference analyzers operating in the regulatory stations. To enhance the sensor accuracy, field calibration, and data correction with reference instrumentation is a valid strategy to improve sensor data quality. In this study, a sensor system with a selected set of air quality gas sensors (NO2, O3) and particulate matter (PM10, PM2.5) has been developed and deployed in a near-city space-airport at Grottaglie (Southern Italy) to perform measurements in a period of 4 months, from October 2021 to February 2022. The sensor units installed in the Airbox system used for this measurements campaign are the GS+4NO2 (DD Scientific) for NO2 measurements, the O3-3E1F (City Technology, Sensoric) for O3 measurements, and the NextPM (Tera Sensor) for PM10 and PM2.5 measurements. Data gathered by the low-cost air quality sensors have been compared to reference instrumentations both co-located (ca. 1 m distance) together with low-cost sensors (PM10, R2 > 0.87; PM2.5, R2 > 0.50) and a distributed regulatory network of 14 environmental stations operating in the local area around space-airport at a distance ranging from 3 to 26 km
Wireless Sensors Network Monitoring of Saharan Dust Events in Bari, Italy
No full textA sensors network based on 8 stationary nodes distributed in Bari (Southern Italy) hasbeen deployed for urban air quality monitoring during advection events of Saharan dust in theperiod 2015⁻2017. The low-cost sensor-systems have been installed in specific sites (buildings,offices, schools, streets, airport) to assess the PM10 concentration at high spatial and temporalresolution in order to supplement the expensive official air monitoring stations for citizen sciencepurposes. Continuous measurements were performed by a cost-effective optical particle counter(PM10), including temperature and relative humidity sensors. They are operated to assess theperformance during a long-term campaign (July 2015⁻December 2017) of 30 months for smart citiesapplications. The sensor data quality has been evaluated by comparison to the reference data of the9 Air Quality Monitoring Stations (AQMS), managed by local environmental agency (ARPA-Puglia)in the Bari city
Urban Air Quality Monitoring with Networked Low-Cost Sensor-Systems
No full textA sensors network based on 11 nodes (10 stationary and 1 mobile mounted on public bus) distributed in Bari (Italy) has been deployed for urban air quality (AQ) monitoring. The low-cost sensor-systems have been installed in specific sites (buildings, offices, schools, streets, port, airport) to enhance environmental awareness of the citizens and to supplement the expensive official air monitoring stations with cost-effective sensor-nodes at high spatial and temporal resolution. Continuous measurements were performed by low-cost electrochemical gas sensors (CO, NO2, O3, SO2), optical particle counter (PM1.0, PM2.5, PM10), NDIR infrared sensor (CO2), photo-ionisation detector (total VOCs), including microsensors for temperature and relative humidity. The sensors are running to assess the performance during a campaign (June 2015–December 2017) of several months for citizen science in sustainable smart cities. The air quality index (AQI) for a given pollutant has been measured and compared to the public reference environmental data. The results of the AQ monitoring long-term campaign for selected sensor-nodes are presented
Rete di monitoraggio della qualità dell'aria. Infrastrutture e realizzazione
No full textQuesto documento presenta le attività che hanno portato alla realizzazione di un’infrastruttura per il monitoraggio ambientale che si basa su dispositivi per il rilevamento di inquinanti atmosferici gassosi, polveri sottili, e parametri ambientali, utili a definire lo stato di qualità dell’aria in aree urbane. Tale infrastruttura permette un controllo in tempo “quasi” reale degli inquinanti atmosferici monitorati e basa il proprio funzionamento sui dispositivi multisensoriali AIRBOX, interamente prodotti all’interno del Laboratorio Test Sensori del Centro Ricerche ENEA di Brindisi, che ne costituiscono gli elementi cognitivi dispiegati sul territorio e che formano una rete wireless per la raccolta dei dati di interesse. I dati di misura forniti dagli AIRBOX vengono filtrati, aggregati ed elaborati secondo modalità che possono variare in funzione dell’utenza cui sono destinati: si passa dalla trasmissione dati secondo protocolli di comunicazione protetti, contemplati per un’utenza tecnico/scientifica, alla più intuitiva interfaccia web che consente una più immediata consultazione dei dati anche da parte di utenze meno esperte. Tale infrastruttura si presta ad un utilizzo su più fronti che possono variare dal semplice monitoraggio statistico della presenza di inquinanti, alla produzione di dati per lo sviluppo e la verifica di modellistica ambientale, al non meno importante supporto decisionale per gli organi che quotidianamente si interfacciano con problematiche ed aspetti connessi alla qualità dell’aria ed al benessere generale. L’infrastruttura è stata fortemente voluta ed incentivata in contesto “smart cities” per un’applicazione diretta nel Progetto RES-NOVAE: in tale occasione è stata dispiegata una rete di monitoraggio sull’area metropolitana di Bari con il posizionamento di AIRBOX su strutture fisse e mezzi mobili. La rete di monitoraggio ha visto il dispiego dei nodi durante il secondo semestre del 2015 ed è operativa al momento della stesura di questo documento.This paper deals with the implementation of a research infrastructure as a sensor network for urban air quality monitoring. It is based on distributed devices (sensor-nodes) for measuring air pollutants such as toxic gases and particulate matters, including other environmental parameters, to understand the air quality level in the urban areas. This tool allows to achieve a nearly real-time tracking of the atmospheric pollutants concentration by multi-parametric sensor-systems, called AIRBOX, completely designed and fabricated in our Sensor Test Laboratory at ENEA Research Center in Brindisi. These sensor-systems (sensor-nodes) have been deployed over the targeted area to form a wireless network for gathering data of environmental interest. Measurements provided by sensor-nodes (AIRBOX) are filtered, collected and processed covering a wide spectrum of use: from scientific purposes, with data delivered by protected communications protocols for science and technology community, to environmental informatics services with friendly webuser interfaces at easy reading for not-skilled users (citizens). This sensors network can be useful for several purposes: monitoring of the targeted air-pollutant levels, delivering data for chemical weather forecasting and air quality modelling, providing information to support the decision-making process of the local authorities devoted to the public health and related to air quality monitoring. The sensors-network described in this paper has been strongly pursued in the “smart cities” context
and demonstrated in the “RES-NOVAE” national project. To achieve this goal, a wireless network composed by AIRBOX sensor-systems has been deployed in the urban area of the Bari city for air quality monitoring. The sensor-nodes have been placed both in stationary sites and on mobile vehicles like public buses. This monitoring network has been deployed on July 2015 and at the current time we are writing this paper is still working

Linkage of Pfister forms over semi-global fields
No full textWe study linkage of -fold quadratic Pfister forms over function fields in one variable over a henselian valued field of 2-cohomological dimension . Specifically, we characterise this property in terms of linkage of quadratic Pfister forms over function fields over the residue field of the henselian valued field; in full generality in characteristic different from 2, and for most complete discretely valued fields in characteristic 2. As an application, we obtain a proof that -fold quadratic Pfister forms over function fields in one variable over a -dimensional higher local field are linked.23 pages, author accepted manuscrip
Modern money theory: some basics in response to Drumetz/Pfister
No full textThis article examines the misconceptions about modern money theory (MMT) put forward by . The author divides her critique into three categories. First, the Drumetz/Pfister article erroneously indicates that MMT focuses exclusively on the means-of-payment function of money, that it considers money as a pure asset, that it does not distinguish between inside and outside money, and that it does not distinguish between money and the monetary base. Second, Drumetz/Pfister (2021) falsely represent MMT as leaving monetary policy to law and as belittling the impact of quantitative easing. Drumetz/Pfister misunderstand what is meant by government debt being monetized. Third, their article puts forward the incorrect idea that increased government spending could lead to increased long-term interest rates, and that a zero interest rate could supposedly bring about macroeconomic instability and inflation
