The retrofitting of buildings for improved energy efficiency has been recognized as crucial achieving climate mitigation goals in Bosnia and Herzegovina (B&H). However, performing multi-objective optimizations existing poses challenges, it requires balancing conflicting objectives such retrofit costs, savings, CO2 reduction. To tackle this challenge, we employed a analysis approach that aims to identify Pareto-optimal solutions retrofitting, striking balance between consumption, emissions,...

This study presents an in-depth analysis of the cost structure when planning EE retrofit measures in residential sector Bosnia and Herzegovina. The showed that implementing would result substantial energy savings single-family houses, however, specific per resident for houses is on average 2.8 times higher than other three categories; multi-family apartment buildings, high-rise buildings. When considering ratio between investment costs GDP capita citizens Herzegovina have four lower ability...

This study investigated the potential for energy savings and reduction in CO2 emissions hospital buildings Bosnia Herzegovina (B&H), through implementation of renovation measures. The building sector B&H is characterized by significant consumption, hospitals account a substantial portion total consumption public buildings. analyzes certain measures selected buildings, including installation thermal insulation on exterior walls flat roofs, photovoltaic plant roof. Preference Selection...

Hospitals, as highly energy-intensive buildings, significantly contribute to a country's energy consumption and CO2 emissions. The study focuses on hospital building in Sarajevo, Bosnia Herzegovina, investigates the impact of selected renovation measures primary main goal this paper is develop mathematical model for establishing relationship between emissions (responses), three (factors). research uses dynamic simulation building's performance Design Builder, validated with actual...

Drying of textiles in industrial facilities represents an energy-intensive process where a large number measures for energy and production cost savings can be introduced. Typical include the introduction management, waste-heat recovery, optimization so on. is complex with coupled heat mass transfer between heated air humid textile, parameters such as flow rate, velocity its regime textile water content represent significant influential factors. The distribution temperature density inside...

Generated power of thermal plant is closely related to efficient work cooling towers, via condenser pressure affected by output temperature water. Performance characteristics system can be rated several parameters such as: effectiveness, Merkel number, number transfer units, and overall heat mass coefficient. Results gathered during acceptance test Kakanj (unit 7) which consists 12 wet counterflow induced draft are used evaluate its most important performance characteristics. It shown that...

This study investigates the influence of ultraviolet (UV) radiation on mechanical properties Fused Deposition Modeling (FDM) 3D printed materials, specifically polycarbonate (PC) and polylactic acid (PLA) specimens. The research involves conducting experiments five test specimens each material exposed to UV comparing their those control that remain unexposed. results reveal a significant mean difference between UV-exposed materials. caused decrease in tensile strength for PC material, while...

Energy saving potentials related to steam generation and its usage in the medium size bakery are analyzed presented. Input data needed for investigation gathered through detailed energy audit. Four savings measures analysed detail: 1) change of heat generator space heating domestic hot water preparation from boiler condensing boiler, 2) reduction losses condensate distribution lines, 3) utilization return 4) replacement old, low efficiency with high-efficient one. Implementation these will...

Breakup of the isothermal, distilled water falling film on a vertical plate is examined experimentally for three regimes: wetting initially dry plate, rewetting and breakup thin liquid film. Sandblasted copper, stainless steel, aluminum galvanized metal sheet are used as material. inclined performed steel with inclination angle 45°, 60° 90°. A minimum liquid-flow rate, thickness corresponding contact measured. Dimensionless rate dimensionless presented function following angles: advancing an...

Abstract This paper presents the energy and CO 2 saving potential of existing district heating system. Analysed system fully rely on fuel oil, with significant losses, increased consumption emission resulting from outdated oversized high greenhouse factor. Heat generation thermal distribution systems efficiency are assessed, showing that overall is 48.5%. System environmental impact shown via absolute specific per heated surface area useful energy. The study proposes retrofit measures to...

Naučnoistraživački projekti tipologije stambenih objekata provedeni u Republici Srbiji (RS) i Bosni Hercegovini (BiH) omogućili su generisanje baze zgrada klasificiranih skladu sa metodologijom predstavljenom evropskom projektu „Tabula“. Zgrade klasificirane prema periodima izgradnje kategorijama 39 kategorija RS 28 BiH. Za svaku kategoriju izabrane tipične zgrade, arhitektonskim karakteristikama svedenim na projektno stanje za koje je izvršen detaljni proračun energetskih karakteristika,...
