GreenDIGIT: Greening Digital Infrastructures with Sustainable Architecture and Design Principles

GreenDIGIT: Greening Digital Infrastructures with Sustainable Architecture and Design Principles The book provides a systematic and forward-looking framework for improving sustainability and energy efficiency in digital infrastructures and data centres across their full lifecycle. The book begins with a structured analysis of the sustainability landscape and identifies the major technology trends, operational challenges, and strategic drivers that are shaping the transition toward more sustainable digital infrastructure systems. It presents sustainability not as an isolated technical issue, but as a cross-cutting design principle that must be addressed from planning and architecture to deployment, operation, monitoring, and governance. A distinctive contribution of the book is its integration of conceptual, technical, operational, and regulatory perspectives. It offers a systematic analysis of the relevant standards, regulations, metrics, KPIs, and industry best practices that increasingly define environmental sustainability in digital infrastructures and data centres. At the same time, it provides architecture frameworks, lifecycle models, design principles, monitoring approaches, and technical examples that help translate sustainability goals into practical engineering and management decisions. The book aligns with Life Cycle Assessment methodology and adapts it to digital infrastructures, supporting a more rigorous treatment of both operational and embodied environmental impacts. Written as both a reference work and a practical handbook, the book is intended for researchers, application developers, infrastructure operators, managers, auditors, and decision-makers. It also introduces Green and Environmental Sustainability Competence as a structured domain for academic curriculum development and professional training. By connecting architecture, lifecycle thinking, operations, monitoring, compliance, and competence development, the book provides one of the first broad and coherent treatments of sustainability by design for digital infrastructures.
