Germany – Engineering services – Zweckverband der 12 Gemeinden des ehemaligen Amtes Thronecken - Energetische Sanierung der Kindertagesstätte Regenbogen, Los 2: Planungsleistungen der Technischen Ausrüstung HLS und Elektro

The purpose of the Zweckverband der 12 Gemeinden des ehemaligen Amtes Thronecken is to renovate the Kindertagesstätte Regenbogen in Thalfang. As part of the planned renovation, the Kindertagesstätte is to be brought up to the Efficiency House 70 standard. This is to be achieved, on the one hand, by improving the building envelope through insulation measures and, on the other hand, by renewing the heat generation, distribution and transfer. It is planned to bring the entire building envelope to the energy level of a new building through suitable insulation measures. This requires that all components adjacent to the outside air be improved in terms of their thermal transmittance values beyond the requirements of the Building Energy Act (GEG). The following measures are planned for this purpose: - Insulation of the facade with 18cm insulation material in the thermal conductivity group 035, - Replacement of all windows with triple-glazed windows, - Insulation of the roof with a combination of intermediate and over-rafter insulation, - Insulation of the flat roof, - Room-side insulation of the floor slabs. The outer walls adjacent to the ground should also be improved as much as possible, provided that the cost-benefit factor is profitable. As part of the energy renovation, the plant technology is also to be modernised. To this end, the existing heating system is to be completely converted to heat generation via a heat pump, which will supply the underfloor heating system with the heat generated. By means of ground probes, which supply the heat pump, renewable energy is to be used for heating in the future. This system is also to be used for cooling in the future. Furthermore, it is planned to completely renew the heat distribution and transfer. Thus, a modern and intelligently controlled underfloor heating system is to ensure low heat consumption. In this context, the lower building closure, the floor slab, is also to be improved energetically. The screed must be removed due to the installation of the underfloor heating, which offers the opportunity to use modern, well-insulated floor structures. In addition, the electricity requirement of the building is to be covered to a large extent by a photovoltaic system in the future. The measure is funded from public funds. A grant application (EFRE) has been submitted, which has already been approved, with the consequence that the specifications of the concept for the energy calculation of the planned renovation, the EFRE funding call and the specifications of the grant notification must be implemented in planning and construction terms. The cost focus of the renovations is on the building-related energy renovation measures, i.e. on facade insulation, roof/upper storey ceiling insulation, floor slab/cellar ceiling/cellar wall insulation, replacement of windows/external doors/ curtain wall facades (plus expenditure for summer heat protection possibly in the form of a combined solution via the windows), for necessary building automation, control and regulation as well as ventilation systems, in accordance with the specifications of the grant notification, with at least 70%. The specifications of the EFRE grant notification are binding and must be complied with. For further details, reference is made to the enclosed scope of services, which is part of the tender documents/contract documents.
