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 Zweckverband der 12 Gemeinden des ehemaligen Amtes Thronecken plans to carry out the energy renovation of the Kindertagesstätte Regenbogen in Thalfang. As part of the planned renovation, the Kindertagesstätte is to be brought up to the Effizienzhaus standard 70. 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 intended 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 external air be upgraded in terms of their thermal transmittance coefficients beyond the requirements of the Building Energy Act (GEG). The following measures are planned for this purpose: - Insulation of the facade with 18cm of 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 external walls adjacent to the ground should also be significantly improved, provided the cost-benefit factor is profitable. As part of the energy renovation, the plant engineering 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 transfers the generated heat to the underfloor heating system. Renewable energy is to be used for heating in the future by means of ground probes, which supply the heat pump. This system is also intended to be used for cooling in the future. Furthermore, it is planned to completely renew the heat distribution and transfer. 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 energetically improved. The installation of the underfloor heating requires the screed to be removed, which offers the opportunity to use modern, well-insulated floor structures. In addition, the electricity demand 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 funding 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 complied with in terms of planning and construction. The cost focus of the renovations is on the building-related energy renovation measures, i.e. on facade insulation, roof/upper floor ceiling insulation, floor slab/cellar ceiling/cellar wall insulation, replacement of windows/external doors/post-and-rail facades (plus expenditure for summer heat protection if necessary 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 mandatory. For further details, reference is made to the enclosed scope of services, which is part of the tender documents/contract documents.
