Evaluating the environmental performance of 45 real-life wooden buildings: A comprehensive analysis of low-impact construction practices

Building and Environment, Journal Year: 2024, Volume and Issue: 250, P. 111201 - 111201

Published: Jan. 15, 2024

Buildings are responsible for 37 % of global Greenhouse Gas (GHG) emissions. Subsequently, stakeholders in this sector have introduced different strategies to reduce the environmental impact buildings. One strategy focuses on increasing use wood buildings as a low-impact material with potential act carbon sink. Although research shows tendency towards lower GHG emissions from structures compared conventional constructions, existing literature is typically challenged by methodological inconsistencies and only assesses limited number building projects at time. As result, uncertainties about comparisons between them, how their background modeling assumptions may vary, well integrity assessed solutions. Hence, study analyses 45 cases applying same methodology enable comprehensive understanding performance wooden buildings, identifying common trends, challenges, best practices. This finds that embodied impacts contribute highly thus remain essential consider. However, there very weak correlation quantities used but strong insulation, plastics, composites, POCP, ODP, ODP EP, respectively. Therefore, these materials should be optimized further

Carbon Footprint Assessment of a Novel Bio-Based Composite for Building Insulation

Sustainability, Journal Year: 2022, Volume and Issue: 14(3), P. 1384 - 1384

Published: Jan. 26, 2022

This research explores the carbon removal of a novel bio-insulation composite, here called MycoBamboo, based on combination bamboo particles and mycelium as binder. First, an attributional life cycle assessment (LCA) was performed to define footprint European plantation well its ability remove CO2 along lifecycle at laboratory scale. Secondly, Global Worming Potential (GWP) estimated through dynamic LCA with selected end-of-life technical replacement scenarios. Finally, building wall application analyzed measure saving potential MycoBamboo when compared alternative insulation materials applied exterior thermal composite system. The results demonstrate that despite negative GWP values biogenic CO2, final Net-GWP positive. scenarios had influence values, longer storage period is preferred more frequent substitution. type energy source deactivation phase play important roles in mitigation climate change. Therefore, make competitive system industrial scale, it fundamental identify low-energy modes shift all energy-intensity activities during production renewable energy.

The construction sector, responsible for 37 % of global greenhouse gas emissions and 36 energy consumption, is transitioning towards a low-carbon low-energy model. Measuring optimising Operational Energy related in the use phase buildings has entered both markets regulations. However, Embodied within materials respective maintenance end-of-life processes still research phase. Moreover, Global Warming Potential baselines per built square metre need to be defined integrating operational embodied impacts. This main goal identifying first time Whole Life Carbon (WLC) average Spanish residential period 1981–2010, broken down into (EC) (OC).

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.
