Building Sustainability with Volcanic Ash: A Green Roof System Innovation

This research introduces a novel approach to urban sustainability through the application of volcanic ash in green roof systems. Addressing the ecological challenges of urban heat islands and biodiversity loss, the study explores the potential of volcanic ash as a sustainable and efficient alternative to traditional green roof materials. Its unique properties, including superior water retention, effective drainage capabilities, and beneficial minerals, are thoroughly investigated. The methodology involves the systematic collection and processing of volcanic ash samples, followed by a series of comprehensive analyses. These include particle size distribution, compaction characteristics, and hydraulic properties. The study provides a comparative evaluation of volcanic ash in green roof applications, highlighting its advantages such as lower energy requirements for processing, reduced structural load, and potential for decreased long-term maintenance costs. Furthermore, the environmental impact, cost-effectiveness, and alignment of volcanic ash use with global sustainability goals are critically assessed. Moreover, building energy simulation is implemented to simulate the energy performance of a building equipped with a volcanic ash-based green roof system in comparison to commercial substrates and estimate the possible real efficacy of the proposed solution. The research concludes that volcanic ash significantly enhances the sustainability and resilience of urban environments, offering a scalable and environmentally friendly solution for green infrastructure development. It paves the way for further exploration and application in urban settings, promoting ecological balance and advancing sustainable urban planning.
