On the 7th of August 2018, Minister of Education Karin Prien handed over the funding approval. Due to high operating costs for heating and hot water preparation in the Sankelmark Academy, the German Border Association has decided to commission an energetic refurbishment for the building construction and the technical building equipment sector. The energetic refurbishment of the Sankelmark Academy is supported by the Landesprogramm Wirtschaft (2014-2020) with funds from the European Regional Development Fund (ERDF). Education Minister Karin Prien handed over the official funding decision on 7 August 2018 during a visit to the Sankelmark Academy. The estimated costs of the conversion measures amount to around 1.8 million euros and are subsidised by 50% from the state programme for industry. The Sankelmark Academy was opened on 29 June 1952. Initially, the conference centre had only one seminar room and 24 guest rooms. Gradually, the German Border Association expanded its capacity to four seminar rooms, additional working rooms for groups , 57 guest rooms and, most recently, a new restaurant and kitchen. Today the Academy Sankelmark consists of the main building from 1952, an annex to the kitchen from 2004, the seminar building from 1972, the first dormitory from 1964 as well as the second dormitory from 1986. Due to the different years of construction, in some cases decades ago, the individual buildings have different renovation and optimisation needs from an energetic and economic point of view. The energetic renovation of the Sankelmark Academy is planned and implemented in accordance with the guidelines for the funding of energetic optimisation investments in institutions of general, political and cultural education. The refurbishment consists of two phases and will run from July 2018 to mid 2019. In 2018, the entire heating system and the hydraulic equalisation of all buildings will be completed. From spring 2019, the local heat pipe to the adjacent guest houses as well as the roof and the exterior windows will be renewed. A gas CHP unit and a gas condensing boiler are planned for the heating system conversion in the main building. The existing heating circuits will be connected to a new heating distributor with modern and controlled circulation pumps. The buildings are mainly heated by radiators, which are calibrated simultaneously with the works in the boiler room and thus ensure the necessary regulated hydraulics in the heating system. The hot water supply to the buildings is ensured by means of fresh water stations and replaces the conventional storage tank variant.
The annual decrease of energy consumption will amount to approx. 270 MWh/a when the overall measure is implemented. This corresponds to a saving of approx. 85,000 kg CO2 per year.
