Dataset on the thermal performance of green roofs and green walls in a temperate continental climate: An experimental approach in Quito, Ecuador

2025 , Villacis Ormaza, Marcelo

This dataset comprises temperature and humidity measurements obtained from two experimental building prototypes designed to characterize the thermal behavior of green roofs and green walls in a temperate continental climate. The data was collected at an elevation of 2850 m above sea level in Quito, Ecuador (−0.120694, −78.498677). At 15-min intervals, calibrated digital sensors recorded the temperature and relative humidity indoors over the course of four months. Values from two configurations are included in the dataset: one that integrates green infrastructure and another that acts as a base case devoid of vegetation. With possible uses for building simulations, urban climate studies, and policy creation, the data are organized to promote study on thermal comfort, energy efficiency, and sustainable construction methods.

The Progression and Shift from Sustainable to Regenerative Architecture Design Concept

2024 , Villacis Ormaza, Marcelo

The buildings’ development and construction have contributed negatively over the years to the increase of the environmental footprint and have also affected the biosphere and society’s quality of life. For several decades the architectural discipline has studied various concepts and methods to mitigate and reduce these effects through sustainability until the concept of regenerative development. This process has been categorized by analyzing each era’s different paradigms, attributes, methodologies, and challenges through a timeline that allows us to know the causes of the evolution of sustainability in architecture. The literature review shows that another vision of how to understand sustainable architecture has emerged, making the concept serve as a relative means of raising awareness for the solution of environmental problems, where it is not the building regenerated as such, but rather the habitat processes that collectively focus on improving people’s lives through resilient ecological systems. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

An Experimental Study on the Thermal Performance of Intensive Green Walls and Green Roofs in Temperate Continental Climatic Zones

2025 , Villacis Ormaza, Marcelo

Green facades and roofs are prevalent in various building typologies across most climatic regions. In warm contexts with the presence of cooling needs, numerous empirical and theoretical studies showcase the effectiveness of these systems in regulating the internal thermal conditions of spaces. The research addresses a gap in the literature concerning experiences with living green roof and green wall systems in cold climatic conditions. Considering the climate in Quito, characterized as a 4C type climate according to ASHRAE, which entails combined heating and cooling needs, this research aims to assess and compare the thermal performance through an empirical methodology based on the construction of two physical prototypes—one with vegetated elements and one without. Throughout the investigation, a comprehensive database of temperature and relative humidity records was compiled from four experiments conducted during both dry and rainy seasons. The findings of the experimental study indicate that these systems not only help in lowering temperatures during the day but also possess the capability to maintain temperatures during the night and early morning and addresses that during periods of heavy rainfall, yet the vegetated prototype exhibited consistent thermal performance, indicating resilience to adverse weather conditions. These findings suggest that green walls and roofs can maintain their effectiveness even in challenging weather scenarios.
