Since 2017, this chart has continuously tracked the development of energy consumption in buildings owned and managed by the City of Prague. The resulting value of energy consumption in buildings is mainly influenced by climatic conditions during the heating season. For this reason, the energy consumption values are recalculated using the degree-day method. This calculation method allows for the balancing of seasonal climatic fluctuations and a fairer comparison of energy consumption. You can learn more about this method here: https://vytapeni.tzb-info.cz/tabulky-a-vypocty/103-vypocet-denostupnu.
*in 2022, the heat consumption value was not available
**in 2025, there was a change in the structure of the monitored buildings, so this data cannot be directly compared with previous years

Carbon footprint monitoring is based on the climate commitment that Prague joined in 2019. The carbon footprint is calculated based on knowledge of the energy consumption of individual energy carriers, with subsequent conversion according to a table based on Decree No. 140/2021 Coll., on energy audits. The goal of the climate commitment is to reduce the carbon footprint by 45% compared to 2010. Prague is currently preparing projects intended to help reduce CO2 production in buildings managed by the Prague City Hall. For this reason, we expect this chart to show a declining trend in the coming years.

Remote readings of billing meters help to determine energy and water consumption more accurately. Billing meters are owned by distribution companies, which install remote reading devices on their equipment. The chart shows the rate at which distribution companies are replacing older types of meters with new, so-called smart meters.

There are a number of ways to generate electricity from renewable sources. One of them is generating electricity using photovoltaic panels. This method of generating electricity saw a boom particularly around 2010. Since then, interest in these technologies stagnated until recent years, when the growth trend in the number of new installations of this technology has returned, as clearly shown in this chart.

The Smart Prague Index yearbook has been published since 2017 by OICT, a city-owned company. Using specific measurable indicators and annual evaluation, the Smart Prague Index analyses Prague's development, tracks trends, summarises the capital city's achievements and serves as a valuable basis for its further development.
*All of the data used in the Smart Prague Index come from individual city organisations, Prague city districts and other partners who are responsible for their accuracy.
