Building climate-friendly: Minister Ahnen visits wooden buildings on the Hahn

Büchenbeuren (ots) - The facades of the three wooden buildings of the Police University (HdP) on the Hahn gradually change from reddish brown to silver gray. This is intentional: The cladding of the outer walls was deliberately left untreated, because Douglas fir exposed to the weather ages without loss of quality and impresses with its natural look. This is just one of the advantages of building with wood, of which Finance and Building Minister Doris Ahnen and the State Secretary in the Ministry of the Environment, Dr. Thomas Griese, were convinced at an information appointment at the HdP student dormitory. The state government promotes the use of renewable building materials together with the state property and construction management company (LBB). Each of the three-storey wooden buildings offers 42 single rooms, each with almost 16 square meters. There are two lounges, kitchens, shower rooms and toilets on each floor. Concrete was used only sparingly in the form of floor slabs for the foundation, as concrete screed on the wooden ceilings and for the stairs made of prefabricated reinforced concrete. The load-bearing structure is a wooden frame construction made of vertical posts and horizontal transoms made of spruce wood and prefabricated thermally insulated wall elements, technically: wooden panel construction. The 18 centimeter thick thermal insulation consists of cellulose, a wood fiber product that is also contained in the gypsum fiber boards of the partition walls. In the rooms, the spruce wood surfaces of the walls ensure a pleasant living environment. ”A sustainable, resource-saving and climate-friendly policy has been part of Rhineland-Palatinate for a long time. We have set ourselves ambitious goals - the state administration should work in a climate-neutral manner from 2030. The state's buildings play a central role in this because they have a significant share in the total energy requirement and greenhouse gas emissions. In order to achieve this goal, we have strengthened measures for climate protection in state properties. The measures also include the increased use of wood as a building material. Wood is a particularly sustainable, environmentally friendly building material and already makes an active contribution to climate protection during growth, since trees bind climate-damaging greenhouse gases from the atmosphere. In addition, wood is extremely versatile and convinces with short construction times. Components can be manufactured for all areas of application; there are particular advantages, for example, for serial construction as well as for conversion and top-up measures. Last but not least, wood often enables inexpensive construction and promotes regional forestry, particularly in Rhineland-Palatinate. The accommodation buildings on the Hahn are an excellent example of the targeted use of the advantages of timber construction. The experience encourages us for further projects in timber construction, "said Finance and Construction Minister Doris Ahnen Refugees without compromising the quality of the building. In September, the state began erecting the first of a total of three identical accommodation buildings on its premises at Frankfurt-Hahn Airport as a pilot project in wood construction, which is particularly suitable for modular prefabrication and short construction times. The first building was completed in December. The Ministry of Finance and Construction commissioned a timber construction company from Rhineland-Palatinate to implement the project, which contracted several regional craft businesses for the construction work. A little later, the LBB state company was commissioned to oversee the production of houses 2 and 3. The third and last building was already completed in June 2016. Environment Secretary Thomas Griese added: "The climate protection efforts of our forest in Rhineland-Palatinate are remarkable, which is why we want to focus more on timber construction, as stated in the forest declaration of the state government." The CO2 is stored in the wood, which the tree needed to grow. “Our forests offset around 9,8 million tons of CO2 per year. That corresponds to a quarter of all CO2 emissions in Rhineland-Palatinate, ”said Griese, who was delighted with the growing demand for wood as a building material. In Rhineland-Palatinate alone in 2019, 24 percent of building permits in residential construction had been granted for projects with predominantly wood as a building material, and 14 percent for non-residential construction. "Our forest-rich state benefits from this along the entire value chain," Grieser was certain. After the buildings were no longer needed as first-time accommodation due to the significantly reduced number of refugees and the University of Police (HdP) had registered the need for campus-related living quarters for students, the LBB state establishment set up six kitchens and lounges in each building within a few weeks and installed a locking system. The planning concept for the buildings was already designed, among other things, to enable later conversion with the least possible effort. The police officers moved in from mid-December 2016. The 126 single rooms are all occupied, however the attendance figures are currently reduced as a measure for corona prevention. Dr. Axel Henrichs, Deputy Director of the Police College, said: “The unexpected availability of 126 additional accommodations for our police commissioner candidates in relative proximity to the campus of the Police College (HdP) came in handy in autumn 2016 because the accommodations were running out on campus itself. However, the acceptance of the new accommodation living space by the HdP students was not a sure-fire success. However, the existing reservations disappeared after the first occupancy in January 2017. The students explain that the wooden surfaces in the interiors, which are cozy and cozy, as well as the communal kitchens and lounges and the parking spaces directly in front of the houses, are very positive. In addition, the external framework conditions were gradually further developed with the active support of the LBB state operation and with the help of the police department, particularly through the redesign of the outdoor facilities and the establishment of an internet connection from the WiFi4RLP program. The 'wooden houses' are now part of everyday living for police students at the University of the Rhineland-Palatinate Police. Benches and tables are made of wood, as is the cladding for the bicycle storage room, open spaces have been landscaped with natural meadows and trees. In the same year, the pilot project was recognized as part of the Rhineland-Palatinate Timber Construction Award. The deputy managing director of the LBB state company, Dr. Petra Wriedt said: “For LBB, the use of timber construction is the consistent continuation of its long-term strategy of sustainable and energy-efficient construction. As early as 2006, the LBB, with its guidelines for energy-efficient construction and renovation, imposed a voluntary commitment to exceed the applicable targets of the Energy Saving Ordinance EnEV wherever possible. We also attach great importance to sustainability on the consumption side. For example, since 2012 we have been tendering for 100 percent green electricity for our building users. Currently 1.500 delivery points are supplied with green electricity, and thus a large part of the state properties. LBB is well positioned for the coming projects with wood as a climate-friendly building material. "
