Heating system monitoring in housing: transparency enables optimisation

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.

Data Instead of Assumptions: How Transparency Unlocks New Efficiency Potential in Existing Buildings

Traditional refurbishment measures are costly, complex and rarely scalable in the short term. At the same time, regulatory pressure, CO₂ costs and ESG requirements continue to rise. In this interview, Dr Dirk Then, CEO of the noventic group, explains why data-driven transparency in heating system operations is the key lever for efficiency in existing buildings – and why digital solutions are no longer an optional add-on, but a prerequisite for an economically viable heat transition.

Christmas fundraising campaign: Giving joy together

While the Christmas season is a time for joy and celebration, it is also a time when many individuals and families face challenges in fulfilling their wishes. It is therefore particularly gratifying when support is provided in a way that is responsive to identified needs. In 2024, the employees of the noventic group once again participated in the campaign „Aktion Tannenbaum“ organised by the Der Hafen hilft! association. This initiative aimed to bring a little Christmas joy to people in social institutions.

Consumption certificate for greater energy transparency

The energy performance certificate is an important document for the energy rating of properties. It documents the actual energy consumption of a building over a period of three years. It provides precise data on energy consumption per square metre and year for heating and hot water. As a transparent tool, it enables an informed assessment of energy efficiency, identifies potential savings and is therefore an important basis for planning refurbishment measures. In a market environment of rising energy costs, decarbonisation pressures and the growing importance of climate change mitigation measures, the energy performance certificate is an important indicator for property owners, as well as an important location indicator for buyers and tenants.

Intelligent Energy Monitoring for Buildings

Whether due to legal requirements or rising energy costs, the pressure to reduce energy consumption is increasing. On this basis, transparent and efficient organisation of energy use is essential for the housing industry and the property sector. A key tool for this is energy monitoring, which is able to systematically record and analyse consumption data and identify appropriate measures for improvement.

The role of SRI in the future of the housing industry

The Smart Readiness Indicator (SRI) is a comprehensive assessment tool designed to evaluate the technological intelligence of buildings. It is specifically intended to assess a building's capacity to integrate smart technologies. Since its introduction in Germany in 2020, based on the EU Energy Performance of Buildings Directive (EPBD), the SRI has been designed to optimise the potential of smart technologies in the building sector. A higher SRI rating indicates greater efficiency in automated self-management and energy consumption adaptation. This is intended to encourage both owners and users to capitalise on the benefits of smart building technologies.

GdW initiates showcase for 'intelligent heating systems

The German housing industry umbrella organisation GdW is launching a showcase entitled 'Shaping together: the smart heating showcase for the housing industry' for rented apartment blocks. The framework is designed to assist small and medium-sized housing companies in becoming familiar with the use and effects of smart thermostats, which have been developed specifically for use in the housing industry, in their own housing stock. The noventic retrofit solution achieves average energy savings of 15.5% at building level and the legally required hydraulic balancing is implemented in a legally compliant manner.

Christmas fundraising campaign: #wärmegeben in Hamburg

Poorly insulated' and #GivingWarmth are two slogans with which Hanseatic Help is drawing attention to the needs of Hamburg's needy. Exactly our theme. Because while the weather outside is miserable, we continue to work in the warmth to ensure that Germany finally heats in a climate-friendly way. But many people can neither make themselves a hot cup of tea nor turn up the thermostat to their heart's content. That's why this year we're supporting the campaign of the charity Hanseatic Help together with employees, management and our canteen in Hamburg.
