We Cooperate with the City of Kladno on Preparing an Energy-Plus Neighborhood


The University Centre for Energy-Efficient Buildings of the CTU continues to implement the SPARCS project together with the city of Kladno. The aim is to increase the share of renewable sources in production of electricity significantly.

During the course of February and March, the team of town planners from CTU UCEEB carried out an analysis of development areas of the city with regard to possible future construction of an energy-plus neighborhood that should fit into the city structure organically. Among others, possibilities of connecting to the system of district heating, synergy between the existing built-up area and the new one under, connection to public transport and other points were observed. All partial conclusions will be made more precise over time in cooperation with the city and other engaged parties.

These activities are directly related to aerial thermal imaging of Kladno that took place in the beginning of March. The result will have the form of a city map that shows heat radiation from buildings and infrastructure. “Photographing the city using a heat-sensitive aerial camera took less than five hours on one March night. The aircraft flew at the altitude of 800 meters and it made more than 3.000 aerial snapshots covering the city area of 44 km2. A thermal orthophotographic map will be compiled from them. The supplier company has triangulated the map and converted it into a mosaic at present. The city also plans to make the maps public afterwards,” informed Dan Jiránek, the mayor of the statutory city of Kladno.

„Within the framework of heat-photography, the company carried out the stereophotogrammetric fixing of objects on the premises of the Moskevská 2929 primary school and the calculation of exposure to solar radiation as a pilot project for the city of Kladno, too. Based on the altitude, location, roof angles and yearly total amount of exposure to solar radiation of the object, a calculation of how much solar energy is captured by them within a year was made which can be used for suitable placement of photo-voltaic modules. According to this test output, we can then decide what other buildings to have the calculation of exposure to solar radiation calculated for, too,” added the mayor. The results for the ZŠ Moskevská school indicate that four areas on the school buildings with the total area of 760 m2 are suitable for mounting the photo-voltaic modules. This area constitutes 27 % of the total roof area.

Kladno found the inspiration in foreign experience of Leipzig (the Baumwollspinnerei project), Espoo and other cities. For example, the synergy of the new and old built-up area in one of the first positive energy neighborhoods located in the city of Carquefou not far from Nantes in France is interesting. In that location, the production of energy in the new buildings of the Fleuriaye neighborhood covers their own consumption and almost one half of the energy consumption in the adjacent neighborhood on top of that.
