Effect of Concrete Mix Composition on Greenhouse Gas Emissions over the Full Life Cycle of a Structure

Energies, Journal Year: 2023, Volume and Issue: 16(7), P. 3229 - 3229

Published: April 3, 2023

As the need to determine and monitor carbon footprints (CFs) in construction industry grows given that concrete is a key material this sector, authors of article conducted footprint analysis 15 different mixtures. The method for determining entire life cycle was presented detail. comparative CF an example structure made three significantly strength classes, addition 1 m3 mix. This showed consider emissivity associated with consumption reinforcing steel when selecting most favorable solution terms greenhouse gas (GHG) emissions. study revealed composition mix, primarily type amount cement, has greatest influence on footprint. Furthermore, location geometry structure, as well number floors, should also be taken into account concrete. In analyzed construction, life-cycle phases related incorporation mixture at site (phases A4–A5) those demolition end its C1–C4) constituted approximately 10% average total value emissions over cycle.

Study and Application of Industrial Thermal Comfort Parameters by Using Bayesian Inference Techniques

Applied Sciences, Journal Year: 2021, Volume and Issue: 11(24), P. 11979 - 11979

Published: Dec. 16, 2021

This paper focuses on the use of Bayesian networks for industrial thermal comfort issue, specifically in industries Northern Argentina. Mined data sets that are analyzed and exploited with WEKA ELVIRA tools discussed. Thus, giving predictive value different pairs indoor temperature humidity values according to activity, time, season, verified workplace, were obtained. The results obtained compared other statistical models linear regression used comfort, thus observing within a same range, yet network offered more information since range options interior design parameters (temperature/relative humidity) was work, season conditions. Additionally, if static heat exchange, contribution is noted when considering context actual operability adaptability conditions environment, which promising developing intelligent systems, especially development sustainable settings Industry 4.0 paradigm.

Decision-makers in cities have difficulties implementing an effective climate policy for their own building resources due to the heterogeneous and dispersed distribution of buildings with low energy classes different management specifics. Special zones include old towns, pre-war (before 1945), those built by end 20th century. There is a noticeable shortage methods comprehensive assessment emissions urban complexes, taking into account social, economic, environmental aspects. Exemplary individual examples good thermal modernization practices towards low-emission zero-energy solutions do not solve problem poor-quality environment. This article proposes simple integrated CO2 separate using example medium-sized city Poland. The adopted ASEET methodology takes socio-economic criteria, but above all, technical criteria development. Sensitive information was collected from users owners gathered data matrix.

Abstract The aim of this study was to assess the feasibility creating a prototype self-sufficient houseboat that is capable prolonged independence from power grids and freshwater sources. In design, electricity demand met by photovoltaic installation, energy stored in batteries. Fresh water for living needs may be obtained many sources, depending on environmental conditions, such as through purifying outboard water, desalinating seawater, collecting storing rainwater. No waste production vessel can achieved two ways: treated discharged into body or processed fertiliser later use agriculture. Four possible locations were analysed: Rome, Lisbon, Gdańsk Stockholm. findings reveal length time which unit autonomous emission-free depends geographical location facility. periods when there overproduction energy, system produce hydrogen, donate grid, it its own movement, perform other useful work, e.g. cleaning aerating floating.
