This ambitious project, too, was implemented as part of a public-private partnership between the District of Cuxhaven and DEPENBROCK. The services include planning, turnkey construction, and interim and final financing as well as maintenance of the building, technical installations and outdoor facilities during the warranty period.
DEPENBROCK created the new, barrier-free Cadenberge guest house including a canteen kitchen and complete furnishing as well as an outdoor area with 84 parking spaces. The project was carried out from May 2021 through December 2023. It is now available to trainees undergoing “inter-company” vocational training in civil engineering.
Architecture
Very architecturally impressive due to its arrangement on the site, the building creates different open spaces, such as the inviting forecourt in front of the main entrance in the south, the leisure, sports and green areas in the northeast, and the parking area in the north. The square in front of the new building complex forms a spacious entrance area and is also a meeting place.
Energy and building concept
Inadequate insulation and gaps in the façades and roofs of the old building had driven up heating costs. Moreover, the outdated equipment and technology incurred high maintenance and operating costs. By contrast, the energy and building concept of the new guest house is all the more efficient, economical and sustainable.
High priority was placed on optimising energy requirements during the planning phase. The building envelope complies with the requirements of German Building Energy Act 2021 (GEG), Efficiency House 55. The purpose of this law is to have buildings use energy as sparingly as possible by making extensive use of renewable energies to generate heating, cooling and electricity for building operation.
With this in mind, heat is generated using electrically operated air-to-water heat pumps to cover the base load and gas-fired condensing boilers for the peak load. Areas such as the canteen, sports area and individual adjoining rooms are ventilated via a central ventilation system with heat recovery. A 23-kWp photovoltaic system produces self-generated electricity, which reduces the building’s energy requirements. LED technology is used for the lighting. This innovative technical building equipment concept makes it possible to cover a remarkable 65 percent of the total energy requirement with environmental heat.
