Green building practices to integrate renewable energy in the construction sector: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 22(2), P. 751 - 784

Published: Dec. 15, 2023

Abstract The building sector is significantly contributing to climate change, pollution, and energy crises, thus requiring a rapid shift more sustainable construction practices. Here, we review the emerging practices of integrating renewable energies in sector, with focus on types, policies, innovations, perspectives. sources include solar, wind, geothermal, biomass fuels. Case studies Seattle, USA, Manama, Bahrain, are presented. Perspectives comprise self-sufficiency, microgrids, carbon neutrality, intelligent buildings, cost reduction, storage, policy support, market recognition. Incorporating wind into buildings can fulfill about 15% building's requirements, while solar integration elevate contribution 83%. Financial incentives, such as 30% subsidy for adoption technologies, augment appeal these innovations.

The levelized cost of energy and modifications for use in electricity generation planning

Energy Reports, Journal Year: 2023, Volume and Issue: 9, P. 495 - 534

Published: July 20, 2023

The Levelized Costs of Energy/Electricity (LCOE) is widely used to compare different power generation technologies by considering the various fixed and variable costs as a single cost metric. levelized electricity measures average net present generating electric over plants entire life. As metric, energy does not capture all that affect like system costs. For accuracy analysis, LCOE modified account for other e.g., which considers externalities. value-adjusted (VALCOE) metric developed International Energy Agency (IEA) captures value since same amount may be less or more valuable during peak demand. storage (LCOS) another applied in comparing alternative systems specific scenarios i.e. long-term, short-term, medium-term storage. Another related avoided (LACE) n information about how grid operates without new plant facility entering service making it complex than LCOS, but insightful. both system.

The increase in global surface temperatures will surpass the 2 °C target set by Paris Agreement unless carbon emissions are lowered to zero 2050. To date, building sector is responsible for 38% of all emissions, thus one main targets represented development strategies that can facilitate transition toward carbon-neutral buildings. today nearly energy buildings (nZEBs), (ZEBs)/net (NZEBs) and net (NZCBs). Particularly, NZCBs completely operational embodied during their life cycles, fulfilling leadership role decarbonization construction sector. Moreover, adopting European Standard EN 15978:2011, be precisely classified enhance aimed at reducing them. Commercial viability remains a fundamental economic driver, but higher initial capital costs hinder NZCBs. In addition, legislative, socio-cultural, technological, professional geographical barriers hold back its diffusion. met four-steps program: reduction, renewable supply offset storage. Circular economy principles strictly connected design disassembly adaptability reduce carbon, while passive solar geothermal production satisfy demand building. aim this narrative review determine describe which current state art NZCB definition, drivers application broader context eligible meet ambitious goal emissions.

The European Union (EU) is accelerating its clean energy transition in order to reach climate neutrality 2050 through targeted policies, with the Energy Performance of Buildings Directive (EPBD) playing a pivotal role reducing building consumption. This study evaluates progress EU Member States implementing EPBD requirements, focusing on Long-Term Renovation Strategies (LTRS), Nearly-Zero (NZEB), Certificates (EPC), and technical system inspections. Harmonized data enable cross-country comparisons, revealing trends across climatic zones assessing policy impacts at level. Aligning renovations 2020 LTRS could cut greenhouse gas emissions by 35% 2030 94% 2050. Despite well-established status NZEB, their performance lags behind benchmarks all zones. Moreover, diverse EPC methodologies complicate in-depth yet nearly 70% certification schemes define classes based an indicator. Finally, over 75% have implemented heating cooling inspection schemes, but few assess impacts.
