Energy transparency

from Wikipedia, the free encyclopedia

Energy transparency describes the transparency of all energy flows and the resulting costs in a particular building or organization. Just like z. B. Cost transparency, it is an important part of successful energy controlling .

description

A typical way of billing electricity consumption , for example , consists of a monthly or annual reading of a meter that adds up the total consumption of the electricity customer. This information is usually not sufficient for a careful analysis , planning and, if necessary, optimization of the power consumption. If you want to save energy , more information is usually required:

  • where energy is consumed in the building or in the organization ,
  • when energy is consumed,
  • what the energy is used for,
  • what alternative courses of action exist

as well as possibly

  • who is causing the consumption

If all this information is available, there is energy transparency.

Components

Various things are necessary to create energy transparency:

  • Sensor technology : The energy flows are monitored with the help of sensors at a sufficient number of points in the distribution system to make them traceable. The measured values must be available as time series , not just as instantaneous values , in order to be able to understand processes.
  • Processing, e.g. B. Visualization : The recorded data is prepared in a comprehensible and traceable manner so that it can be communicated . The addressed target group must be adequately taken into account. Business-trained people can use the data for controlling.
  • Networking: In the commercial sector in particular, responsibility for various aspects of energy consumption is shared among different actors , possibly many. In order to involve all actors in planned measures, the information on energy consumption must be available to all those involved and they must be able to exchange ideas.

Measurements

Energy transparency requires continuous control of all electrical devices and their energy consumption in the building. Some providers of smart home solutions offer smart metering options here .
