Rising cost pressures are increasingly forcing owners and operators of buildings in both the public and private sectors to search for potential cost savings in building operations. A key focus is on all costs associated with energy and media supply. The method by which these costs can be sustainably reduced is technical building management. While there are several publications on the overarching topic of facility management, technical building management is often treated too broadly. In particular, methodological aspects, or "how do I do this in detail," are often overlooked. This is where the present book comes in. It focuses on the methodological approach to planning, implementing, and executing technical building management. Detailed explanations are provided.
