Elek Gyula Arena complex energetic modernisation

This summary describes possible areas of intervention for the energy modernisation of Gyula Elek Arena. We summarised only those modifications that are rational and in any way reduce the operating costs of the installation. The Arena, originally built for the Ganz Companies Sports Hall, was built in 1997. In the two decades since its opening, the structural, technical building and lighting solutions used at the time of construction are now considered to be significantly outdated and need to be upgraded. The proposed adaptations target three main areas. • Architectural alterations • Building engineering alterations and related electrical transformations The walls and slab structure of the building show the picture created at the time of construction, none of its structural elements comply with the applicable building energy regulations and requirements. As a result, the maintenance costs of the building are very high. The existing roof structure, the shell of which in the initial position does not contain or hardly contains thermal insulation, is used for conversion. The roof structure of the hall roof would put 22 cm of stone wool thermal insulation and PVC waterproofing if the roof structure could be technically loaded to this extent. The side walls of the building are quite fragmented, with large fixed windows and walls rotating along the perimeter of the building. The technology of doors and windows uses plastic frames, but its structural heat transfer value is far below today’s expectations. The walls of the building include thermal insulation, but the thickness of the layer is up to 4-5 cm.AA uninsulated exterior surfaces and outdated windows cause high heat loss, causing unreasonably high heating costs. During reconstruction, the facade is insulated from among the building structures and the doors and windows are replaced. The insulation of the facade in the case of heavy masonry is made with EPS material thermal insulation, the mounted metal masonry is replaced by a sandwich panel with rock wool thermal insulation. Thermal insulation on the walls is made in 16 cm thickness, sandwich wall panel is made in 17.5 cm thickness. It is also recommended to replace doors and windows with 6-7 chamber structure and three-layered glass to reduce heat loss in the winter. Older wooden/plastic-structured windows are replaced by a plastic structure with three layers of heat-insulated glazing. Older metal-structured windows/doors, where technically permissible plastic structure, are replaced by three layers of heat-insulated glazing. The older metal-structured curtain walls, larger doors, where we replace technically necessary metal structure with three layers of heat-insulated glazing. With regard to the feed-in side of the heating system, the hall is connected to the on-site heating system using the steam carrier medium, which is supplied from the small gas turbine power plant of the Kőbánya Power Plant. The steam carrier is now outdated, it is difficult to regulate it. On the secondary side of the heating system you can find both air-technical elements (hallroom heating) and radiator systems (view room, changing rooms, service block rooms). Some elements of the current air system need to be adapted (e.g.: heat recovery elements). A condensing boiler room is installed during planned alterations. The boiler room supplies heat to the existing radiator system, ventilation machinesIt. In addition, the boiler room supplies HMV production.
