MOHOHO - Modular wooden high-rise

High population growth combined with an increasing degree of urbanization cause a growing demand for new buildings in urban areas. At the same time, the construction industry is responsible for about 60 % of the global resource consumption, for about 50 % of the global waste generation and for about 50 % of the global emissions of climate-damaging gases. This contrasts with the national emission reduction targets agreed with the EU, which calls for a 55 % reduction in greenhouse gases by 2030 and aims to become completely climate-neutral by 2050. In order to meet the ambitious goals of the EU Green Deal, all levels of sustainability must be addressed. Based on the Sustainable Development Goals (SDGs) and the principle of reduce, reuse, recycle, these levels are successively worked through and implemented with the holistic system solution. The MOHOHO research project develops, investigates and provides functional proof of a modular timber construction solution for high-rise buildings. It combines the high degree of prefabrication of timber modular construction with the flexibility and resource efficiency of skeleton construction. On the one hand, the focus is on the development and investigation of a circular-economy and resource-optimized skeleton module with demountable partition walls for possible conversions. On the other hand, a connection node is developed and investigated, which allows a subsequent replacement of whole modules or module elements independent of the supporting structure. The advantage is that the failure of individual modules (fire or water damage) does not lead to the collapse of the entire building. This should make urban timber construction more resistant and evolvable (resilient) to external or internal influences. The results of the research project will be made available to the timber construction industry in the form of reference books and publications. They contain floor plan solutions based on this system, pre-dimensioning tables, comparisons with comparable systems, details, static calculations, descriptive graphics and explanations of the system solution. Furthermore, the results serve as a basis for subsequent research projects or dissertations aiming at a development ready for series production.
