Centralized heating: systems for individualization of facilities and consumption
In the following section you will find complete information on how to adapt the centralized heating installations of your building and your home to comply with the obligation to install individual meters, whenever it is technically feasible and economically profitable, so that you can know and optimize your consumption. actual energy.
Since the entry into force in 1999 of the Regulation of Thermal Installations in Buildings (RITE), the installation of each user in a building of new construction with system centralized heating must have a counter, that allows you to distribute the costs according to your consumption.
In regards to the existing buildings at that time and that they had central heating, the Directive 2012/27 / EU imposed obligations related to the individual accounting of energy consumption, including that relating to thermal energy from centralized heating systems.
With this directive, recently modified, it is intended that the consumer have the right to know your spending periodically, to be able to adapt the use it makes of energy and pay part of the cost of heating the building, based on your individual energy demand. This directive has recently been transposed into the Spanish legal system through the Royal Decree 736/2020, of August 4, which regulates the accounting of individual consumption in thermal installations of buildings. This regulation establishes that every existing building with a centralized thermal installation (heating or air conditioning) that caters to multiple users:
You must have a system that allows measure or estimate the energy consumption of each user.
End users must have the means necessary to control their own consumption.
The reading and invoicing or distribution of costs of the expenses to each user must be carried out respecting certain requirements (remote reading, information on invoices, among others).
The owners of the facilities are responsible for carrying out these adaptations in certain deadlines and in accordance with the established procedure.
According to the estimates offered by the Institute for Energy Diversification and Saving (IDAE), as well as the experience in this regard in European countries where its use has been widespread for more than forty years, ultimate energy saving for all the users of the installation with the individual distribution of expenses, It is usually higher than 30%.
In the territorial scope of the Community of Madrid, there is a study by the University of Alcalá de Henares, from December 2016, which quantifies this saving above 25%.
