Replacement of light bulbs, new windows, insulation of buildings. Town halls in Prague started to save money
The first stop was Klánovice, the greenest part of Prague. The local secretary answered the question of savings: “When winter asks what we did in the summer, we will answer that we started with a seemingly small thing – replacing all light bulbs and fluorescent lamps with LEDs.” From the office to the fire station, from the library to the seniors’ club,” Petr Vilgus listed.
Thanks to this replacement, they saved over 2,000 W of resource consumption at the local authority alone. In addition, the town hall consulted experts on how to replace the 30-year-old atmospheric gas boiler in the town hall building.
Energy for the whole office
“A visit to the boiler room used to resemble a trip to the history of the gas industry in the Czech lands. Thanks to a subsidy from the municipality, we are installing a heat pump over the summer. And the company also installs a photovoltaic power plant on the roof of the building. The pump will work down to minus 15 degrees Celsius,” explains Vilgus.

Computers, air conditioning, lighting… Thanks to the photovoltaic power plant, Klánovice should produce enough energy to cover the consumption of the entire office.
Boilers were also replaced in Kolovraty. “Thanks to this, we managed to reduce energy consumption in buildings by more than 40 percent. At the same time, we want to change the light sources to LED lighting, which is far more efficient and less expensive,” Antonín Klecanda told the Prague newspaper. “In this way, we want to minimize the costs of rising energy prices so that there is no need for drastic cuts in some parts of the budget.”
At the next stop, in the heart of the metropolis in Prague 1, they plan to save in the coming months by lowering the heating temperature and an economical ventilation system.
Costs fell by 12 percent
Prague 7 has published a way to reduce the energy demand of its buildings. “Thanks to the modernization of eleven buildings in our administration and the economical energy management of our town hall, the costs of gas, electricity and water will be reduced by 12 percent, which now represents 2.32 million crowns per year,” revealed the deputy mayor Prague 7 Kamil Vavřinec Mareš.
In addition, in 2019, the City Hall of Seven decided to use the method of energy services with a guarantee, so savings are contractually guaranteed for 12 years.
“We are also currently modernizing three nursing homes and eight schools. Savings due to renovated gas boilers, new LED lighting and modernization of the measurement and control system. Sewerage will be reduced by 400 thousand crowns thanks to the installation of toilet stops and aerators. And the most significant cost savings will be the installation of a computer system in six elementary schools. His task is to monitor the temperature set according to the use of the given space,” explained Deputy Mayor Mareš.

Insulation and replacement of windows in kindergarten and primary school buildings or modernization of town hall buildings in Bratří Venclíků Street. Thus, it reduces the energy demand of buildings in Prague14.
“At the same time, we will take a number of steps, the goal is not only savings as such, but especially support for environmental protection. At public events in the district, we use returnable cups, buy in large packages or use companies from the surrounding area so as not to increase the carbon footprint,” said Veronika Berná, spokeswoman for Prague 14.
In Prague 5, a working group is currently preparing material for the City Council – a proposal for measures that will deal with energy savings. “This material goes to the Council on Monday, August 22, so we will be wiser after that date,” concluded Lenka Abessi, spokeswoman for Prague 5.
