... makes an outstanding contribution to sustainable building typologies, while venturing far beyond prevailing construction standards and the current discourse surrounding sustainability in architecture. It is worth noting that the project did not receive the German Sustainable Building Council (DGNB) Gold Seal.

The restructuring within the project company also led to delays in the planning process. Ultimately, the project benefited from the difficult circumstances that it underwent on the way to its final concept, and the “WOODCUBE” ...
However, the new team put together by DeepGreen thoroughly matched the quality of that in the competition.
Since repeated attempts were made throughout the project to implement genuine innovations, the planning process often reached a point where the whole project came into question. Process Evaluation+
The stated aim of the IBA Hamburg has always been to implement the project using the team that won the competition. This did not happen in the case of the “WOODCUBE”. ... to that of a Passive House. If we look at the building’s energy requirement purely in terms of the numbers, it comes to 18 kWh/m2 per year, which is roughly equivalent to the Passive House standard.
... the positive material properties of solid wood construction in terms of energy efficiency cannot be attained through conventional methods. The actual energy consumption is likely to be similar ...
The Thoma Holz100 system, which was thermally optimised in collaboration with various experts, now makes it possible for the “WOODCUBE” to achieve the KfW-40 standard. As several studies show, the considerable advantages offered by ...
... contradict “WOODCUBE’s” holistic approach, which is based on sustainable construction that is free of toxic substances. This once again demonstrates the need for the rigid rules of the energy conservation regulations (EnEV) to be revised.
... was no longer part of DeepGreen’s agenda after switching to solid wood construction, as glued insulating materials and airtight levels that prevented diffusion would have been necessary. Such requirements for the building’s shell directly ...
Energy Standard TSB Ingenieurgemeinschaft drew up an energy saving plan for the “WOODCUBE”, in compliance with the 2009 energy conservation regulations (EnEV). Passive House certification, which had originally been one of the “WOODCUBE’s” goals,
