Abstract Carbon reduction during the operational phase of buildings is a critical component in achieving global carbon neutrality objectives. Current methods for estimating dioxide emissions this predominantly focus on national or city-level scales, often ignoring heterogeneity building types and functions. This oversight limits precision with which low-carbon management technologies can be applied to retrofit existing effectively. To address gap, we develop building-based accounting approach at city-scale that considers type, function, floor area, height individual building. Additionally, integrate point source data from facility-level power plants characterize structure energy supply sector. We then propose suite emission tailored buildings, constructing baseline, regulatory, blueprint scenarios analyze pathways 2020 2050. The demand-side primarily target two key areas reduction, such as modifying consumption behaviors by replacing conventional lighting energy-efficient alternatives. On supply-side, three major technological categories are addressed, including conversion coal-fired coal-biomass co-firing systems enhance generation efficiency. methodology city Nanjing, encompassing 534,000 across 101 streets. Our analysis reveals intensity terminal use commercial Nanjing approximately 3.9 times higher than residential buildings. Enhancing efficiency end-use sectors HVAC systems, lighting, electrical equipment emerges most effective strategy reducing From supply-side perspective, early retirement offers significant contribution reductions. accelerates transition more efficient phasing out outdated capacities before 2045 optimizing deployment advanced technologies, solar, wind, nuclear. findings offer targeted provide valuable scientific insights policymakers.

Life cycle analysis (LCA) is a crucial instrument in the construction industry, offering comprehensive evaluation of environmental impacts at every stage building’s lifecycle. Recently introduced into Finnish legislation, this approach has not yet been thoroughly researched relation to Ministry Environment (FMoE) assessment method, nor have new calculation techniques proposed address its shortcomings. Furthermore, research on impact predominantly focused residential buildings, leaving scarcity studies office buildings. This paper aims fill these gaps literature, considering LCA, carbon footprint, and handprint tools concrete-, timber-, steel-framed cases. Our results are as follows: (1) majority footprint concrete-framed case originated from emissions associated with energy use second largest share total occurred during product phase building within phase, services contribute most product-related emissions; (2) significant portion came facades floor structures; (3) timber-framed option was significantly lower than that concrete- counterparts; (4) option’s nearly equivalent option; (5) estimated considerably higher options, primarily due storage capacity timber components; (6) surpassed because high recycling reuse potential steel (7) LCA method used by FMoE some unclear areas. These ambiguities include how assess carbonation cement-based products replacement components.
