With the continuous development of global economy, carbon dioxide and other greenhouse gas emissions are persistently increasing, making warming an indisputable fact. As a high-energy consuming industry, building industry has gradually emerged as primary source during urban expansion. Consequently, countries exploring sustainable pathways for low-carbon buildings to minimize detrimental impact caused by construction industry. This paper summarizes current status and, through literature analysis concerning standard systems emission accountings, discusses challenges possible improvements future. Establishing quantitative evaluation tool elucidating accounting methods in field is fundamental prerequisite comprehensively studying throughout their life cycle. The follows: (1) lack set measurement standards that can be commonly used internationally, (2) deep systematic study theory accountings (3) difficulty recognizing boundaries related data existing methods. provides comprehensive progress development, along with examination optimization application methodologies within address challenges.

The European Union (EU) has implemented several policies to enhance energy efficiency. Among these is the objective of achieving energy-efficient renovations in at least 3% EU buildings annually. primary aim this study was offer a precise environmental comparison among four similar district-heated multifamily that have undergone identical efficiency measures. key distinguishing factor them lies HVAC systems installed. chosen were as follows: (1) exhaust ventilation with air pressure control; (2) mechanical heat recovery; (3) an pump; and (4) pump Photovoltaic (PV) panel. This involved life cycle assessment relied on actual material data from housing company consumption measurements. covered period 50 years for thorough analysis. A sensitivity analysis also conducted account various future scenarios production. findings revealed building exhibited lowest greenhouse gas emissions shortest carbon payback (GBPT), needing only around 7 years. In contrast, without recovery showed highest longest requiring approximately 11 Notably, results significantly influenced by production, emphasizing crucial role emission factors determining performance distinct renovation scenarios.

Air conditioning (AC) has become the fastest-growing energy end-use in buildings worldwide, and its adoption is expected to increase further due various socioeconomic factors climate change. Despite this, decarbonization of space cooling progressing slowly; hence, emissions burden at each stage should be examined detail. Given this context, it crucial assess environmental performance AC systems by considering a comprehensive approach like Life Cycle Assessment (LCA). While several studies have already targeted LCA systems, clear overview those studies' methodologies, assumptions, results still lacking. Therefore, systematic review methods key findings 41 peer-reviewed articles. Although revealed discrepancies among goals scope, impact assessment methods, indicators, most articles predominantly focused on global warming potential (GWP) impact, reported quantification was analyzed. It observed that grid-connected vapor-compression heat pumps/chillers (conventional systems) presented higher GWP impacts than other powered renewables, which contrast, exhibited some toxicity resource depletion-related indicators. However, share showed different distributions, as pre-operation solar-powered (either PV or thermal) were conventional mainly driven reduced consumption usage. This concludes with recommendations for life cycle. Since operation phase generally highest more efforts devoted accelerating transition 100% clean electricity power system national scale. In need on-site renewables carefully assessed based context.
