Positive Energy Districts (PEDs) represent an innovative approach to thinking and designing cities sustainably, in compliance with the European Union energy strategy. This strategy integrates sectors such as urban planning, energy, construction synergistically address environmental challenges. Studies on sustainability assessment systems applied PEDs evidenced that they focus mostly aspects, while few include a comprehensive life cycle of equivalent CO2 emissions, considering building component impacts materials used. Additionally, most assessments are conducted district scale, Neighborhood Sustainability Assessments (NSA), which begin correlate dynamics selecting sustainable for green-certified projects, analyzed throughout entire cycle, relying adoption Green Building Rating Systems (GBRS) at scale. To explore impact environmentally friendly (i.e., ‘green’) GBRS certifications selection products according criteria, encourage their use projects explicitly referring PEDs, this study analyzes technical solutions implemented two significant residential renovation Italy from PED perspective. It proposes classification system based required targets efficiency, production, flexibility. The results definition expandable portfolio solutions, analytical comparison between used case studies examined, criteria provided by voluntary ’green’ certification tools (GBRS). collected evidence offers operational framework confirms positive related development, contributing scientific debate PEDs. Furthermore, scale can be encouraged context transition towards aiming identify specific indicators integrated into future certifications. aims contribute creating self-sufficient areas, focusing sustainability, innovation, line global emission reduction climate change mitigation goals.

Transitioning to Positive Energy Districts (PEDs) is essential for achieving carbon neutrality in urban areas by 2050. This study presents a multi-objective optimization framework that balances energy, environmental, and economic performance, addressing the diverse priorities of multiple stakeholders. The enhances PED design systematically evaluating technical solutions, including renewable-based electrification, demand-side management (DSM), energy storage, retrofitting. applied Usquare district Brussels, Belgium, as case study. results indicate expanding photovoltaic (PV) capacity crucial targets, with electrification potentially reducing emissions up 79%. incorporation (DSM) battery storage improves system flexibility, reduces grid dependency, cost-effectiveness. Although slightly more costly, retrofitting existing buildings provides most balanced approach, offering lowest CO2 highest self-consumption ratio. comprehensive decision-making support optimizing operation, practical guidance planning contributing global efforts toward neutrality.

ABSTRACT Smart local energy systems (SLESs) are central to enhancing localization and decentralization of the sector. Although these widely studied in literature, Nordic conditions probabilistic approaches have remained out spotlight. This study analyzes economically optimized configurations for a SLES. We define cost levels at which various technologies become feasible invest in. also evaluate life cycle emission reductions achievable from systems. Our case utilizes Monte Carlo optimization with integrated economic models. The results 2000 cost‐optimized SLES years 2020–2023 indicated that compared baseline, levelized electricity reduced 98% cases, while specific greenhouse gas emissions 97% cases. mean positive carbon handprint was 44%. Maximum costs deploy were 30 €/MWh wind power, 500 €/kW solar 120 €/kWh battery storage. Thermal storage commonly utilized. outcomes highlight importance sector integration context SLESs, as cases achieved large especially heat carrier. indicate SLESs could be viable mitigation.

Introduction With increasing urbanization, the frequency of extreme weather events, and intensification urban heat island (UHI) phenomenon, there is a growing concern about outdoor thermal comfort (OTC) in rural spaces. However, previous OTC studies have been dominated by empirical case regional sample points lacked systematic large-scale exploration within certain region. Methods This study used preferred reporting items for reviews meta-analyses (PRISMA) method bibliometric tools to statisticians sources, keywords, content highly cited papers studies. Results Based on quantitative results, this sorts organizes research from characterization, methods, trends, summarizes following results: (1) Universal climate index (UTCI) relatively suitable research; (2) The combination subjectivity objectivity with application Artificial Intelligence (AI) current cutting-edge OTC; (3) Local zone (LCZ) classification system has potential be future potential. Discussion collated results studies, proposes framework provide necessary theoretical support practical guidance planning construction, which will help optimize environment improve quality life residents.

Current building energy modeling (BEM) tools lack the capability to inherently simulate impacts of urban microclimates on performance. While efforts have been made integrate BEM with Urban Microclimate Modeling (UMM) tools, their ability capture spatial and seasonal microclimate variations remains limited. This review critically evaluates existing microclimate-integrated approaches effectiveness in complex interactions between form, microclimate, Through an analysis 94 research articles, first examines influence form microclimates, followed by assessment how microclimatic conditions impact use. Additionally, it conventional frameworks employed limitations representing dynamic variations. The findings emphasize non-linear heat exchange relationships typically modeled using computationally intensive Computational Fluid Dynamics (CFD)-based UMM tools. introduces a classification types: atmospheric exchange, involving air temperature, wind, humidity, non-atmospheric driven radiative surrounding surfaces. study further highlights that modifying standard weather files transfer coefficients alone is insufficient for accurately near-surface By identifying critical insights gaps, this establishes foundation advancing next-generation approaches, emphasizing need efficient dynamically responsive techniques.
