(1) Background: Urban villages in Guangzhou are high-density communities with challenging outdoor thermal environments, which significantly impact residents’ comfort. Addressing these issues is crucial for improving the quality of life and mitigating heat stress such environments. (2) Methods: This study utilized a validated ENVI-met microclimate model to explore synergistic cooling effects roof greening facade greening. Three types—total greening, greening—were analyzed their impacts on air temperature, mean radiant physiologically equivalent temperature (PET) at pedestrian height 1.5 m under varying green coverage scenarios. (3) Results: The findings showed that total exhibited greatest potential, especially high (≥50%), reducing PET by approximately 2.5 °C, from 53.5 °C 51.0 during midday, shifting level “extreme stress” “strong stress”. Facade reduced about while had limited effect, 1.0 °C. Furthermore, exceeding 75%, achieved maximum reductions 3.0 1.2 temperature. (4) Conclusions: provides scientific evidence supporting as most effective strategy comfort urban villages, offering practical insights optimizing infrastructure.

The automation of environmental assessment processes aimed at reducing the ecological footprint industrial facilities, buildings, and infrastructure is one main challenges currently faced by construction sector. In this context, Building Information Modeling (BIM) a comprehensive methodology that enables creation digital models, facilitating analysis performance throughout life cycle built assets. addition to capabilities offered BIM, specialized tools for impact implement standardized (LCA) methodology. However, current limitations integration BIM models LCA tools. Few software solutions enable automated data transfer, complicating process. objective study evaluate reliability transfer from tools, using an warehouse as case study. research compares two tools: Athena Impact Estimator, in sector, SimaPro, professional tool with advanced capabilities. This structured phases: (i) development model Revit, including definition structural functional components export (ii) execution compliance ISO 14040 EN 15804 standards. results show methodological interoperability differences between highlighting their strengths terms precision results, resource consumption, training expertise requirements, scope calculations, adaptability sector model.
