PROJECT EXAMPLES
INSTITUTE OF PHYSICS
Background
The Institute of Physics of the Czech Academy of Sciences (mainly located in the Prague 8 municipal district) is one of the most prestigious research and scientific institutions in the Czech Republic. It is involved in various scientific and research activities which require a comprehensive, well controlled environment in which different parts of its building have to be concurrently heated and cooled in a cost-effective manner.

Main project goal
To design a heating and cooling system for the new building of the innovation center Brain 4 Industry at Dolní Břežany, as well as its subsequent installation.
Project content
FOSOTRA GROUP provided the following services:
creating a design for the system based on
the application of several different heat pumps using both passive and active cooling (also making use of aquifers and geothermal energy) and
a 4-pipe distribution system with fan coils,
and getting its approval by all the legally prescribed authorities,
procurement of materials and equipment (specified in the approved documentation),
selection and supervision of suppliers carrying out the installation of the system,
commissioning of the new system and supervising its operation over the test period.

Screws & Wire Libčice produces special screws, bespoke designed machine parts, drawn wire, as well as tools for both hot and cold forming. The company’s production facilities span a total area of more than 65,000 m2.
Energy was originally secured as follows:
• power from the public grid,
• heat from a local boiler room,
• cooling from local air-conditioning (powered by electricity from the public grid).

Main project goal
To design and implement a general overhaul of the steam-producing boiler room (heat output 3.9 MWth) and the pipelines supplying steam to individual production workshops.
Project content
FOSOTRA GROUP provided the following services:
creating designs for:
the reconstructed boiler room (projected heat output 3.9 MWth) and
the upgraded steam distribution system (incl. control system) to the production buildings of Screws & Wire Libčice,
and getting their approval by all the legally prescribed authorities,
procurement of materials and equipment (specified in the approved documentation),
selection and supervision of suppliers carrying out the reconstruction,
commissioning the new system and supervising its operation over the test period.
OUTPATIENT CLINIC – JIŽNÍ MĚSTO
Background
The Outpatient Clinic Jižní Město is a healthcare facility with a gross floor area of over 4,000 m2 which provides all kinds of healthcare for outpatients who are mostly inhabitants of Municipal District Prague 4 (Prague’s most populous district with total number of approx. 131,000 inhabitants).
Energy was originally secured as follows:
• power from the public grid,
• heat from a central network fed from the power plant in Mělník (burning brown coal),
• cooling from local air-conditioning (powered by electricity from the public grid).

Main project goal
To design and implement a new control system for individual temperature regulation in particular rooms/groups of rooms to decrease the cost of the consumed thermal energy.
Project content
FOSOTRA GROUP delivered the following services:
creating designs for
the locations of individual sensors and controlling actuators for room-heating radiators, as well as for the incoming supply of energy,
a local area network connecting individual sensors and actuators with a central control unit,
algorithms for the overall control and management of the heating system of the outpatient clinic,
and getting their approval by the client,
procurement of materials and equipment (specified in the approved documentation),
selection and supervision of suppliers carrying out the installation of the system,
commissioning of the new system and supervising its operation over the test period.
Outlook
It is planned that the Outpatient Clinic Jižní Město will become a part of projected Energy District Prague–South (please refer to the Energy District Prague–South Case Study). As a result, future energy supplies will be newly secured from the sources of this ED, thereby guaranteeing that the energy consumed at this facility will be low carbon emission energy, and ultimately zero carbon emission energy.
JANKA RADOTÍN
Background
Janka Radotín a.s. is a mechanical engineering company with a history of more than 150 years. It produces HVAC components and systems, as well as industrial heat exchangers. Janka Radotín a.s. is located in Radotin, a borough in the south-west outskirts of Prague. The production facilities of Janka Radotín cover area of approx. 11,000 m2.
Energy is supplied as follows:
• power from the public grid,
• heat from an external boiler room (burning natural gas),
• cooling from local air-conditioning (powered by electricity from the public grid).

Main project goal
To design and implement a more efficient heat distribution system within production workshops covering a total floor area of approx. 9,000 m2.
Project content
FOSOTRA GROUP delivered the following services:
creating designs for:
a new system of hot water distribution (incl. pipes and pumps), as well as new equipment for radiating thermal energy and
the inevitable changes to buildings where workshops are located,
and securing its approval from all legally prescribed authorities,
procurement of materials and equipment (specified in the approved documentation),
selection and supervision of suppliers carrying out the reconstruction,
commissioning the new system and supervising its operation over the test period.
Outlook
Setting up the Energy District Radotín, which would deliver heat from locally built high-tech glass houses is currently under consideration. If realized, low carbon emission energy (ultimately zero carbon emission) would also be supplied to Janka Radotín a.s.
