The aim of the handbook is to provide municipal actors with concrete tools that can be used to keep and locate production in urban areas. In the joint project UrbaneProduktion.Ruhr, funded by the Federal Ministry of Education and Research, research was carried out from October 2016 to December 2019 into whether and how it is possible to bring production back to the city.
The handbook offers answers to the questions: What will the city of the future look like? And what role do manufacturing companies play in this? How can their number be increased again, especially in the city? The handbook and the research project are the work of: UrbaneProduktion.Ruhr of the Institute for Work and Technology of the Westphalian University of Applied Sciences, the Bochum University of Applied Sciences, the Urbanists and the City of Bochum. For three years, opportunities and challenges of urban production were researched in real laboratories in Bochum-Langendreer and Bochum-Wattenscheid. The focus is on businesses that process or manufacture material products. These include classic craft enterprises such as carpentry shops and bakeries as well as industrial enterprises and urban agriculture.
For one in three Germans, the car is still a status symbol. But due to running costs and the scarcity of parking spaces, more and more city dwellers are giving up their own car. Is it worth relying completely on car sharing?
It was to be the first 6-storey wooden building in NRW, now 5 storeys are being realised as student accommodation with 32 units in passive house standard. The building is located not far from Bonn's main railway station and is implemented with a car sharing concept.
"The raw material wood is precious. It is therefore important to use it responsibly and in a way that conserves resources," warns Peter Aicher, Chairman of Holzbau Deutschland. Even if wood is affected by environmental influences or the bark beetle, it does not represent an inferior raw material, but has almost identical properties to conventional construction timber. "If the so-called 'calamity wood' has the same structural quality in terms of load-bearing capacity as conventional sawn timber, it can be used without restrictions," explains Aicher. In addition, the wood retains its important function as a CO2 sink, regardless of external impairments.
"If the wood is used as a building material, the carbon bound in the wood remains stored there in the long term, thereby significantly reducing the burden on the environment."
The goal must be an economically and ecologically sensible and efficient use of the domestic resource. In the interests of sustainability and climate protection, regional wood resources should therefore be used optimally.
Calamity wood is of high quality and can be used without restrictions
In most cases, bark beetle infestation is irrelevant for the use of the wood as a building material. The bark beetle lays its burrows in the bast, i.e. the area between the bark (bark) and the trunk, but not in the load-bearing wood itself. In addition, the sawn timber is technically dried during further processing. During this process at the latest, any remaining populations of insect pests are reliably killed off, so that beetle-free timber processed into sawn timber is guaranteed to be beetle-free. Every piece of sawn timber - regardless of its origin - must meet the criteria of DIN standard 4074 in order to be used as load-bearing timber in a building. In some cases, the wood turns a slightly bluish colour after a bark beetle infestation. It can then be used in the non-visible area.
Environmental factors and the effects of climate change have further facilitated the mass spread of the bark beetle in the past year. In most cases, rapid felling of the affected trees is the only alternative to stop the further spread of the pest. The logs are immediately removed from the forest and stored. This results in an oversupply of so-called 'beetle wood'. The prompt further processing of the calamity wood into sawn timber is an active contribution to climate protection.
Holzbau Deutschland appeals to the public sector as well as to architects and builders to make greater use of regional calamity wood and to specify this in tenders. The use of domestic calamity wood not only supports regional value creation, but is also a sign of solidarity with regional forest owners.
