The built environment directly impacts human health and well-being, yet most green certification systems prioritize energy efficiency over occupant health. The WELL Building Standard (WELL), launched in 2014, addresses this gap by focusing on the health and comfort of building users. Despite its growing importance, limited academic research systematically examines its global implementation. This study will fill this research gap by analyzing 1559 WELL-certified projects worldwide using the WELL database. The results reveal that 50% of certifications are concentrated in China and the United States, while regions such as Africa and Latin America show minimal adoption. Most projects are office buildings (83%), with fewer in education, healthcare and residential sectors. Additionally, most certified projects have achieved Gold or Platinum levels, and there has been a notable increase in certifications since the COVID-19 pandemic. By identifying geographic and typological disparities, this research provides a global overview of WELL adoption and offers insights for practitioners and policymakers seeking to promote health-focused building practices.

Considerando que una parte importante de la población mundial vive con algún tipo de discapacidad y que la esperanza de vida aumenta, el hecho de tener un transporte accesible permitiría que las personas mejoraran su calidad de vida, accediendo a más oportunidades socioeconómicas. A partir de un diseño descriptivo mixto (cualitativo etnográfico y cuantitativo), este artículo presenta una herramienta de evaluación del nivel de accesibilidad en el uso del tren subterráneo para personas con discapacidad visual, física, cognitiva y auditiva. Se analizaron los datos de 30 estaciones del Metro de Santiago de Chile, estudiando el desplazamiento desde el exterior a la estación, la permanencia en zona de pagos y el desplazamiento hacia andenes y combinaciones. De los indicadores evaluados, los que tienen relación con el desplazamiento hacia el andén son los que presentan menores niveles de accesibilidad, ya que no responden a todas las necesidades para los distintos tipos de discapacidad analizados.

Existing industrialized construction (IC) and lean construction research have mainly addressed IC adoption at organisational and industry levels, identifying barriers, mapping lean techniques, and proposing strategic frameworks, while offering limited insight into the project-level requirements of industrialized construction projects (ICPs) …

Since the late 1960s, project management researchers have studied the factors contributing to project success, with Dr. Barnes introducing the “Iron Triangle” concept in 1969. Initially composed of scope, time, and cost, subsequent interpretations have varied, with quality, stakeholder satisfaction, risk management, and sustainability proposed as additional vertices. However, it is difficult to reach a consensus on the definitive concepts of the Iron Triangle. This study proposes a new Iron Triangle that incorporates the concept of “value” along with cost and schedule, consistent with Lean Construction principles. Through a comprehensive literature review and critical analysis, the study identifies systematically excluded dimensions of the traditional Iron Triangle, emphasizing stakeholder satisfaction, sustainability, and innovation. The research aims to understand how these dimensions enhance traditional project management models by integrating Lean Construction principles. The results reveal a dynamic relationship among cost, schedule, and value, challenging the traditional assumption of inverse proportionality. The proposed model emphasizes the importance of value generation, promoting customer focus, eliminating waste, and continuous improvement. It encourages a holistic approach to project assessment, recognizing the multifaceted nature of success. This new paradigm suggests further research into strategies that assess cost, schedule, and value in construction projects.
