Il miglioramento energetico nel recupero degli edifici storici. Applicazione al patrimonio architettonico palermitano
L'architettura storica può assumere un ruolo rilevante nel raggiungimento degli obiettivi europei di efficienza energetica per il settore edile, obiettivi che, tuttavia, devono essere compatibili con la conservazione del patrimonio storico e del suo valore culturale. A tal fine è necessario far riferimento ai caratteri specifici dell'architettura storica e alla sua dimensione locale. La presente tesi, sulla base di tale assunto, esamina le prestazioni energetiche degli edifici storici e il loro potenziale miglioramento, concentrandosi sul patrimonio architettonico di Palermo, caso di studio significativo per l'area mediterranea. La ricerca, condotta con riferimento sia alla scala urbana sia…
Comparative Assessment of Mould Growth Risk in Lightweight Insulating Assemblies Via Analysis of Hygrothermal Data and In Situ Evaluation
2019
In order to assess the sustainability of buildings with different types of insulating assemblies in the Latvian climate, a long-term test building monitoring experiment has been underway since 2013. There are a total of five test buildings on site with roughly six years’ worth of accumulated temperature and humidity readings in the key parts of assemblies. This study is meant to quantify the mould presence in building walls, floor and ceiling by performing laboratory tests, assessing the number of colony-forming units, and comparing the results with mould risk predictions due to the isopleth model developed by Sedlbauer, using both the hygrothermal data derived from the sensors within build…
Mitruma un siltuma pārneses modelēšana ēku norobežojošās konstrukcijās un iekštelpās
2022
Darba mērķis ir analizēt termisko inerci un mitruma pārnesi reālos laika apstākļos ēkas ārējās izolācijas konstrukcijās, kas sastāv no pētāmā materiāla - kaņepju betona. Šim pētījumam tika izvēlēta viendimensionāla problēmas nostādne WUFI programmatūrā. WUFI aprēķina iegūtie dati tiek salīdzināti ar eksperimentāli iegūtiem datiem. Lai noteiktu mitruma un siltuma pārnesi iekštelpās, tiek izveidots divdimensionāls un trīsdimensionāls telpas modelis ANSYS CFX vidē, iekļaujot termisko starojumu un konvekciju. Ģeometrija tiek izveidota pēc Latvijas Universitātes Botāniskajā dārzā esošā reālā stenda izmēriem. Ar WUFI iegūtie rezultāti pietiekami labi atbilst eksperimentāli iegūtajiem datiem. Izve…
