Understanding heat supply before optimising: Many existing buildings lack reliable data on the actual performance of their heating systems, which makes any optimisation a shot in the dark. This article shows why digital heating monitoring is becoming the foundation of modern operations management: it creates transparency about the real condition of the system, enables data-based decisions and is a prerequisite for effective, economically viable efficiency measures in the housing industry.
Bei den Berliner Energietagen 2025 standen praxistaugliche und kosteneffiziente Technologien für den Gebäudebestand im Mittelpunkt. Experten aus der Wohnungswirtschaft zeigten auf, wie sich mit geringem Investitionsaufwand im wahrsten Sinne des Wortes messbare Energieeinsparungen erzielen lassen.
Professor Dr. Andreas Pfnür, of Darmstadt Technical University (TU Darmstadt), and noventic Managing Director Dr. Dirk Then discuss the noventic study, in which 1,000 tenants were asked about their role in climate protection in the housing industry. How great is their willingness to participate in residential housing climate protection? And what role do costs, automated processes, digitisation and sharing consumption data play?
The federal government’s climate targets pose major challenges for the real estate industry: particularly when it comes to existing buildings, owners and managers face a giant task in coping with the growing demands for energy efficiency and climate protection. The regulatory underpinnings for this are often enshrined both in European law and the resultant derived national legal provisions. In complying with these requirements, without losing sight of precepts of economy and affordable living space, low-investment measures could offer helpful leverage. The digitisation of the building infrastructure lays the foundations for the optimum management of energy installations and maximum consumption transparency for users, as well as allowing portfolio holders also to make valuable efficiency gains.
A development by noventic shows that climate protection can be very simple: The 'Cards' app playfully involves tenants in actively saving energy on a daily basis and, as a side effect, helps to protect the building fabric. The app was awarded the Innovation Prize by the German Property Federation (ZIA) at the Real Estate Industry Day on 13 June 2018.
