Ecology Smarte Lösungen für ein vorausschauendes Energiemanagement
Digression: Smart Metering
In late 2019, DIC Asset AG launched a smart metering project through its fully-owned subsidiary DIC Onsite GmbH. Within the group of companies, the platform of DIC Onsite GmbH is responsible for the facility management, lettings, property management and property development both of the proprietary property holdings (Commercial Portfolio) and of the properties managed for third parties (Institutional Business).
What is smart metering?
The term “smart metering” generally denotes the use of intelligent measuring methods and measuring systems to collect and evaluate building consumption data. Traditionally, measuring instruments have been subject to the distinction between the measurement point operation and the measurement service. The measured data is normally read out in annual intervals. Not until after this (manual) intermediate step do the data become available to the measurement point operator, who forwards them to the actual consumers. An intelligent measuring instrument (a so-called “smart meter”) eliminates this intermediate step because the measurement service is already integrated in the measurement point operation and the data are automatically transmitted via a digital interface.
DIC Asset AG has adopted the goal of installing smart meters at an early stage for all managed properties. In a first step, it is intended to modernise all utility electricity meters. A second rollout will include the replacement of natural gas, district heating and water supply meters. The consumption data received via the digital interface can be docked to different user interfaces and visualized, for instance in an energy portal.
German law mandates the installation of intelligent metering equipment for metering points with a consumption of >6,000 kWh/year and modern metering equipment for those with lower consumption by 2032. The underlying legal basis is specifically the Metering Point Operation Act (MsbG), which came into force in 2016, and the Act on the Digitisation of the Energy Transition (GDEW) of 2015, which are based on the requirements specified in the EU’s directives for the internal market in electricity and gas.
The conversion will make it possible to monitor consumer data in real time, resulting in potentially enhanced evaluation options. In particular, this will permit the introduction of a forward-looking energy management, so that abnormal data values or consumption patterns, for instance, will automatically trigger alerts. The operator is at liberty to set the threshold values that will trigger an alert when exceeded or undercut, and these will be constantly monitored. Excessive consumption, e. g. by the lighting system, lift or heating system, will be detected early on. It also speeds up the response to failures of defective technical equipment. Finally, the increased standardisation and prompt availability of consumption data also implies extra optimisation potential on the portfolio level.
