Thermal Modernization of the Pomeranian Voivodeship Local Government Facilities – Psychiatric Hospitals and Emergency Medical Stations

In 2020-2021, the company 2SUN, in consortium with the company MARBUD, was and continues to be involved in the “Thermal Modernization of the Pomeranian Voivodeship Local Government Facilities – Psychiatric Hospitals and Emergency Medical Stations” project, co-financed by the European Union – European Regional Development Fund.

The thermal modernization covered three facility complexes of the Pomeranian Voivodeship Local Government:

  • The office and social building of the Emergency Medical Station at 5 Paderewski Street in Słupsk,

 

  • Buildings 6A and 7A at the Provincial Psychiatric Hospital named after Prof. T. Bilikiewicz at 15 Srebrniki Street in Gdańsk,
  • Buildings of the Hospital for Nervous and Mentally Ill Patients named after Stanisław Kryzan at 7 Skarszewska Street in Starogard Gdański.

In all of these facilities, thermal modernization of the buildings and installations has been carried out or is currently underway, as described in the following part of the article.

BUILDING THERMAL MODERNIZATION

The thermal modernization of the building involved insulating walls, ceilings, roofs, and floors. Typically, the building partitions were supplemented with an additional, thicker, and higher-quality layer of insulation material, such as reinforced polystyrene or mineral wool.

In these facilities, it was also necessary to replace windows and doors to prevent a significant amount of heat from escaping through the thermally inefficient and leaky window and door joinery.

INSTALLATION MODERNIZATION

The modernization covered installations such as:

  • Ventilation installations,
  • Heating installations,
  • Domestic hot water installations,
  • Electrical installations,
  • Heat supply system from group substations to individual ones with an energy management system.

Ventilation installation modernization – renovation of the existing ventilation system to mechanical ventilation with heat recovery (recuperation). The locations of the ventilation units, air intakes, and exhausts were carefully planned, taking into account the building’s specifications and available free space.

Heating installation modernization – renovation of the heating installation considering the existing heat source. Different solutions were applied depending on the type and specifications of the buildings, also taking into account the comfort and expectations of the installation users. In some buildings, it was sufficient to expand the current heat source, e.g., the substation, with additional circuits. As part of the heating installation modernization, old, inefficient cast-iron or Favier-type radiators were replaced with new, plate radiators, along with the entire piping system and fittings.

Domestic hot water and sewage installation modernization – replacement of pipes, fittings, and sometimes faucets. In one facility, renewable energy – solar energy – was utilized through the use of solar collectors, which help in heating domestic hot water and thus reduce the operating costs of the installation.

Electrical installation modernization – replacement of old electrical wires with new ones, replacement of lighting fixtures with energy-efficient ones, and installation and adjustment of automation to control devices in the facility. In the facilities in Słupsk and Gdańsk, renewable energy sources (RES) were used by installing photovoltaic panels that generate solar energy, which will certainly help reduce electricity bills from the energy supplier.

Modernization of the heat supply system from group substations to individual ones with an energy management system – The modernization will involve replacing the heat supply system equipment from group substations with individual ones in selected buildings of the hospital complex in Starogard Gdański. In the hospital buildings in Gdańsk and Starogard Gdański, an energy management system will be implemented. This system will monitor, control, and optimize the operation of installations and technical equipment in the buildings. The implementation and maintenance of the energy management system aim to enable the user to respond to changes in external and internal conditions to achieve optimal energy consumption, improve functionality, safety, and comfort in the facilities. The installation will be equipped with instrumentation to measure energy and environmental performance. A computerized management and supervision system was used for monitoring, along with professional solutions consisting of energy and heat meters directly connected to the building’s technical systems (ventilation, central heating, electrical installations), equipped with data transmission links to a central server.
