This book discusses how climate change and heat islands are a main contributor to water related problems in urban areas in Kosice, Slovakia. Green roofs are used as a tool to assist in solving these water related issues. The need to provide housing in urban areas is expected to rise to 66% in 2050, according to the United Nations. Many urban areas have seen natural permeable green areas replaced with concrete constructions and hard, non-permeable surfaces. The densification of existing built-up areas is responsible for the decreasing vegetation, which results in the lack of evapotranspiration cooling the air, thereby creating urban heat islands. Several studies, discussed in this book, have shown that natural and permeable surfaces, as in the case of green roofs, can play a crucial role in mitigating this negative climate phenomenon and providing higher efficiency for buildings, leading to savings such as water, one of the focal points of this research.

This book focuses on the access to water in the building and its surroundings, to infer the mutual interaction and the complex interconnection of green/blue infrastructures. This book is a tool for understanding the multifunctional functionality of urban waste water to recognize their efficient and strategically useful potential in the form of aesthetic and functional architectural elements—vertical gardens, waterproof roof systems, rain gardens, retention rainwater recirculation tanks, biomarkers for wastewater treatment, and other progressive technologies and technical solutions. The originality of the proposed book and the innovation of the proposed objectives lies in the complexity and interdisciplinary of the problem solved, with clear continuity and utilization in professional building, environmental, and psychosocial practice. Understanding the quality of life as a category influenced by several objective and subjective conditions, this manuscript draws up recommendations on how to build “green buildings�—progressively supplied with water, connecting infrastructures—from existing buildings (administrative or training).
