Building operations, which include the energy from electricity and natural gas account for about 28% of global greenhouse (GHG) emissions. Stakeholders need accurate assessments building operations in whole life-cycle (WBLCA), at both individual stock-level, to inform mitigation strategy selection, policy development, progress tracking sector GHG emission targets. This review provides an overview estimation methods (measured, modeling, representative empirical modeled databases) factors (average versus marginal, regional utility, direct combustion values) estimating operational emissions WBLCAs. An investigation most commonly used approaches WBLCAs, especially context emerging considerations including grid decarbonization, non-constant supply loads, embodied trade-off decisions, reveals that there is no standard practice justifying method or dataset selection. While many datasets tools discussed this study are developed United States, overarching quantifying use applicable audiences. Based upon literature survey utility each factor dataset, we identify recommended WBLCAs under various goals establishing benchmarks, choosing strategies, implementing on-site renewable generation, forecasting reductions sector.

Understanding the embodied carbon credentials of modern methods of construction

This study assesses the embodied carbon credentials of modern methods construction (MMC) by conducting a critical literature review and synthesis findings. While several studies have reviewed broader impacts MMC, no other to date has comprehensively this typology. Since MMC is not an internationally recognised term, assessment inclusive terminology used in different parts world – e.g. prefabrication, off-site industrialised construction. The captures 250 separate distils these final sample set 41 total 82 case comparisons. Although general perception exists that adoption results savings, evidence support claim robust. from individual range significantly both direction magnitude, and, absence review, considerably conclusions can be drawn.
