Probability estimation of the city’s energy efficiency improvement as a result of using the phase change materials in heating networks

Energy, Journal Year: 2021, Volume and Issue: 228, P. 120549 - 120549

Published: April 6, 2021

One of the problems in cities is improving energy efficiency. Energy consumption and efficient use district heating networks affect environment, society, economy. Modern materials to increase buildings' efficiency become necessary. The phase change (PCM) a current issue many researchers' interest. PCM reduces buildings due their ability absorb release energy. seems be highly justified as regards policy-making considering city's investment scale. Therefore, research was undertaken on possibility reducing city by using municipal networks, those for which planning can carried out systemically. research's original element integrating geographic systems with artificial intelligence statistical methods estimation probability urban areas based an identified set criteria interdisciplinary type. proposed innovative approach used analyze medium-sized located Eastern Europe. results showed that could classified according improvement at limit 30%. Suggestions were made adapting method more general cases.

The European Union’s Energy Policy Efforts Regarding Emission Reduction in Cities—A Method Proposal

Energies, Journal Year: 2023, Volume and Issue: 16(17), P. 6123 - 6123

Published: Aug. 22, 2023

Decisions regarding waste and emission management systems are subject to many sustainability criteria, including environmental, social, economic criteria. The problem is the multidimensionality of energy transformation its reading from different perspectives. This article aims assess effectiveness municipal policy. VIKOR multicriteria analysis approach modeling Criteria Importance Through Intercriteria Correlation were chosen for method. made it possible create a ranking choose compromise solution. analyses carried out four areas intervention (ETS tariffs), in which set general criteria twelve specific distinguished, based on weights assigned, rankings created highlighting activities that have greatest impact low urban areas. Based analyses, was found most significant reducing emissions has led decisions increase investments renewable sources promote reduction household consumption.

Towards Transit‑Oriented Development for Sustainable Urban Mobility: Insights from a Central European City

Geomatics and Environmental Engineering, Journal Year: 2021, Volume and Issue: 15(3), P. 39 - 53

Published: April 27, 2021

Sustainable Development Goals require holistic actions, including activity at the intersection of urban planning and environmental engineering. Turning our cities towards transit‑oriented development might help in reducing pollutant emissions caused by individual transportation modes that rely on crude oil. This research presents how use geospatial network analysis can support local decision makers evaluation potential public transport accessibility citizens case a Central European city – Wrocław (Poland). The obtained results indicate differentiation access to railway stations stops, which from pedestrian path networks number entrances stations. visualization serve area shows parts are excluded comfortable way high‑ light where future actions should be taken.

The Landscape of the Spa Parks Creation through Components Influencing Environmental Perception Using Multi-Criteria Analysis

Sustainability, Journal Year: 2022, Volume and Issue: 14(9), P. 5657 - 5657

Published: May 7, 2022

The improvement of the landscape spa parks should result from planned directions development and most important tasks spatial policy towns. Their proper management significantly impacts region’s economic growth: labour market, size type new financial investments, natural environment. basis activity in areas is balancing elements natural, cultural historical background. Parks are health protection zones, ecosystems—separated zone to protect healing environmental values. These be characterized by rational landscaping. layout park consider appropriate zones (healing, silence, recreation). leading element that allows separating sub-areas alleys greenery. attractiveness also influenced factors related activities. article aims indicate main criteria affecting perception parks. meaning was determined information entropy. A selection defining assessment influencing greenery, which helped determine how shape develop park, presented. Data obtained actual field measurements on reception were considered. multi-criteria method comparative analysis one quickly transparently hierarchy advantageous variables adopted criteria. study confirmed smaller sum adverse shaping spatial, better residents’ patients’ park.

Solvent-Free CO2 Cycloaddition of Propylene Oxide via Novel Composite of SAPO-34/ZIF-8

Published: Jan. 1, 2024

In this research, ZIF-8/SAPO-34 composites with various wt.% of ZIF-8 and SAPO-34 were prepared used as catalysts to synthesize cyclic carbonate solventless from CO2 propylene oxide. Among composites, SAPO-34/ZIF-8 75:25 (S/Z25) had the highest conversion value 92.59%, confirmed by 1HNMR analysis. Various physicochemical techniques characterize optimized composite, including X-ray diffraction (XRD), SEM, FT-IR, BET. The impact different reaction parameters such temperature, time, pressure, catalyst amount on reactivity studied. has been obtained at 120 psi, 100 ℃, 240 min. was decreased 20% when loading changed 0.4 0.1 g. Additionally, catalyst's recyclability for three runs without any significant changes in conversion. However, it observed that after five repeated tests reusability, percentage 92.59% 88.66%.

We are currently in the period of an intensive climate change, resulting from changes heat balance earth’s surface and causing increase temperature lower troposphere levels. According to latest IPCC report 2021, it is human activity that has indisputably caused atmospheric concentrations greenhouse gases, responsible for this process. The consequences change under Polish conditions, apart a rise especially spring winter months, also amount distribution precipitation totals. A slight totals observed, however heavy rainfall significantly more frequent, interspersed with periods droughts heatwaves. Ground frost-free prolonged, negative trend duration thickness snow cover recorded most parts country. Although extreme phenomena occurring Poland permanently inscribed its climatic threat strong winds been increasing recent years, intense often accompanies them cause peak discharges flooding. Forecasts progressive not optimistic, either on global scale or country question. article examines impact design, construction maintenance engineering structures globally Poland. Changes design standards, selected examples disasters solutions adapt build resilience have analysed. For building disasters, factors were direct disaster, although course analysis usually turned out exposed errors and, lesser extent, improper structures. However, there number new approaches creating resilient built environment, including one, which proposes use grey infrastructure cities change.
