Ovrednotenje sistema za upravljanje zgradb z vidika indikatorja pripravljenosti na pametne sisteme

KASTELIC, GAŠPER (author), Humar, Iztok (mentor)

Magistrska naloga obravnava indikator pripravljenosti na pametne sisteme SRI, ki omogoča ocenjevanje zmogljivosti zgradbe ali stavbne enote za prilagoditev njenega delovanja potrebam uporabnika in omrežja ter izboljšanje njene energijske učinkovitosti in splošne učinkovitosti med uporabo. Vključuje funkcije za večje prihranke energije, primerjalno analizo in prožnost ter izboljšane funkcionalnosti in zmogljivosti, ki jih zagotavljajo bolj medsebojno povezane in inteligentne naprave. Oceno pripravljenosti za pametne sisteme je možno izboljšati z uporabo sistemov za upravljanje zgradb. Namen te naloge je ovrednotenje zmogljivosti izbranega sistema za upravljanje zgradb z vidika indikatorja pripravljenosti na pametne sisteme. Osrednji del magistrske naloge predstavljajo izračuni ocen pripravljenosti na pametne sisteme. Ti so izvedeni na treh različnih primerih dvonadstropne stanovanjske hiše, ki vključuje različne tehnične stavbne sisteme in izbrani sistem za upravljanje zgradb. Izračuni so izvedeni v skladu z SRI metodologijo ocenjevanja, ki temelji na ocenjevanju funkcionalnih nivojev pametnih storitev in izraža pripravljenost zgradb na pametne sisteme na podlagi vnaprej opredeljenih ključnih pametnih funkcionalnosti, vplivnih kategorij in tehničnih domen. Rezultati posameznih SRI ocen pričajo o maksimalni stopnji pripravljenosti na pametne sisteme, ki jo lahko dosežemo z izbranim sistemom za upravljanje zgradb. Ugotovitve kažejo, da se izbrani sistem najslabše odreže na področju energijske prilagodljivosti, ki vključuje tudi udeležbo zgradbe pri odzivu na povpraševanje. Na podlagi primerjalne analize rezultatov je ovrednoten tudi vpliv metodologije ocenjevanja na rezultate posameznih SRI ocen. V zadnjem delu magistrske naloge je opravljena analiza zmogljivosti izbranega sistema za upravljanje zgradb z vidika nivojev funkcionalnosti posameznih SRI storitev. Izpostavljene in predlagane so tehnične izboljšave sistema, ki bodo vodile k doseganju višje ocene indikatorja pripravljenosti na pametne sisteme.

• Title: Evaluation of a building management system in reference to smart readiness indicator

Abstract

The master's thesis discusses the smart readiness indicator SRI which enables the assessment of the capabilities of a building or building unit to adapt its operation to the needs of the occupant and the grid and to improve its energy efficiency and overall in-use performance. It includes features for increased energy savings, benchmarking and flexibility, and enhanced functionalities and capabilities provided by more interconnected and intelligent devices. Smart readiness score can be improved by the use of building management systems. The purpose of this master's thesis is to evaluate the performance of the selected building management system about smart readiness indicator. The central part of the master's thesis represents assessment calculations of smart readiness scores. These calculations are performed on three different examples of a two-story residential building, which includes different technical building systems and a selected building management system. The calculations are carried out following the SRI evaluation methodology which is based on the assessment of functionality levels of smart services and expresses the smart readiness of buildings along predefined key functionalities, impact criteria, and technical domains. Results of individual SRI assessments show the maximum level of smart readiness that can be achieved with the selected building management system. Findings show that the selected system performs the worst in the field of energy flexibility which also includes the building's participation in demand response. Based on the comparative analysis of the results, the impact of the assessment methodology on the results of individual SRI assessments is also evaluated. In the last part of the master's thesis, the performance analysis of the selected building management system is performed with reference to the functionality levels of individual SRI services. Technical improvements of the system are highlighted and proposed, which will lead to achieving a higher smart readiness indicator score.
