13088 Berlin:<\/strong> In the WIR quarter, a total of around 12,400 sqm of floor space was created with 207 flats as cooperative rental flats (BeGeno16) and as condominiums (UTB Projektmanagement GmbH), as well as 9 commercial units and common rooms (BeGeno16). Completion: 2020<\/p>\n

Project data
\n<\/strong>Property: 7000 m\u00b2<\/p>\n

Apartment sizes<\/strong>
\nThe 4 five-story buildings offer a mix of 1 to 6-bedroom large single and cluster apartments for shared and group living. The fifth building has been constructed with condominiums. Each building has its own elevator, so that all apartments are accessible barrier-free.<\/p>\n

Energy concept
\n<\/strong>Energy standard: KfW 40 (promotion: KfW 40+)
\nVentilation systems with a heat exchanger that recovers heat from the exhaust air with an efficiency greater than 85 %. In the living rooms and bathrooms, low-temperature radiators or floor convectors are additionally installed to ensure the necessary supply of residual heat.<\/p>\n

Construction \/ Timber construction<\/strong>
\nFive-storey timber building in mixed construction, (timber frame with solid timber ceilings as well as concrete basement and staircases). For all buildings, a uniform load-bearing structure was chosen as a support system with ceiling slabs in solid wood, as well as prefabricated wooden fa\u00e7ade panels with cellulose filling. The timber modular buildings are realized as timber skeleton construction. With a total volume of 3,500 m\u00b3 of timber components used, all floor slabs and facades were constructed in timber.<\/p>\n

The standardisation of three building types with a consistent access system and the use of lightweight walls allow a high degree of flexibility in terms of use. Subsequent changes of use can thus be easily adapted. The flat roofs are greened. BauBuche, which has an extremely high compressive strength with strength class GL70, was predominantly used for the middle rows of columns and beams in this area. The slabs consist of 24 cm thick spruce cross laminated timber elements.<\/p>\n

The timber modular construction method proved to be the best solution not only in terms of time and cost efficiency but also, and above all, in terms of insulation quality. By assembling the prefabricated exterior walls in a first step, followed by columns and ceilings, the building envelope was not only closed in a very short time, but also has airtightness of maximum quality. The construction of an OSB board as an airtight planking layer on the inside for the compartments with blow-in insulation finishes on the outside with an ETICS made of large-format plaster base board made of wood fibre, GUTEX Thermowall-gf in 60 mm, as well as an approved plaster system for the fa\u00e7ade design.<\/p>\n

The plaster facades hardly reveal from the outside that it is a wooden quarter. Inside, wood is visible in the parquet flooring, the wooden windows and above all in the columns. In the large apartments and clusters, the free-standing columns and beams allow flexible use. The skeleton construction simplifies spatial adaptations and even allows for conversion into office space.<\/p>\n

Construction and rental costs<\/strong>
\nThe cooperative Begeno 16 will offer a part of the apartments for rent of eight euros net cold and a part is reserved for young refugees. About 1000 square meters have been built for social offers. According to the calculations so far, the square meter will be 11 euros net cold plus the operating costs prepayment of 2.5 euros. The construction costs are altogether under 3000 euro per square meter. The largest hurdle for prospective customers might represent the cooperative portions. Only those who pay 500 euros per square metre can move in.<\/p>\n
