評委評語

該項目由巴爾科-萊賓格建筑設計事務所領導，旨在為德國漢堡的低成本住宅提供智能材料。在保障性住房的背景下，它是集混凝土技術、類型學、能源效率為一體的一項杰出成就。首先，混凝土技術使其能夠在預制面板系統中裝配特定形狀的墻板元件。只需兩種不同的墻面原型即可進行設計，并使墻面呈現出令人驚訝、富于變化的塑形表現力。根據元件的定位，系統可以產生多種使人眼前一亮的陣列布局。因為墻上只承受垂直載荷（水平荷載由中央核支撐），系統提供了平面布局空間組織的高靈活性。

混凝土墻50cm厚，混凝土由骨料混合回收玻璃，從而使其密度降低至小于800kg/m3。通過使用玻璃纖維代替用于加固的鋼材使得重量進一步減少。蛇形管插入的外層部分的混凝土作為太陽能收集器。由于這些措施，混凝土是自隔熱的并且不需要絕緣材料應用于室外——這使得它可以保持素混凝土的外觀，就像現代主義鼎盛時期那樣，只是這一次，它是為了環保。

一段時間以來，混凝土幾乎不能在其表面沒有設置保溫的情況下使用，這種性能上集成結構和氣候特性的混凝土開辟了混凝土在現代建筑上使用的新軌道。地板板層以疊層木材制作，具有質輕、易于組裝和隔音的性能。評委一致認為其雄心勃勃的形式與結構性能的設定使得這個項目重塑了對社會住宅的認知。這表明社會住宅緊張的預算并不是必須采用重復的形式結構體系。這個項目顯示了實驗性特別是社會住宅的潛力。有一種說法，清晰可辨、令人難忘——迄今為止建筑品質的提升總是更愿意與更大的預算掛鉤。而設計者們聲稱社會住宅項目的建筑形式和材料特性將擺脫歷史的陳詞濫調，開始探索一個全新領域的潛力。

Jury Appraisal

The project led by Barkow Leibinger Architects for low-cost apartments incorporating smart materials in Hamburg, Germany, is an outstanding achievement in terms of concrete technology, typology, and energy efficiency in the context of affordable housing. Firstly, the concrete technology makes it possible to cast wall elements with particular shapes in a prefabricated panel system. Te design can be created with only two different wall prototypes, and yet achieves a surprising variability in the plastic expression of the walls. Depending on the orientation of the elements, the system can generate an astonishing array of variable ground plans. Since the walls only take vertical loads (horizontal loads are taken up by the central core), the system accommodates a high flexibility in the spatial organization of the ground plans.

The concrete walls themselves are 50 cm thick. The concrete is mixed with an aggregate of recycled glass, which reduces its density to less than 800 kg/ m3. Te weight is further reduced by using glass fibre instead of steel for reinforcement. Snake-like tubes inserted in the outer portion of the concrete serve as solar collectors. Tanks to these measures, the concrete is thermally self-insulating, and does not require insulating materials to be applied to the exterior –its bare-faced concrete again, like in the heyday of modernism, but this time environmentally sound.

In a time where concrete can virtually not be used without thermal insulation applied on top of it, this integration of structural and climatic properties within the performance of concrete opens a new trajectory for the use of concrete in contemporary building. Te floor slabs are made of laminated timber, for its lightness, ease of assembly, and favourable acoustic insulation properties. The jury agreed that with its ambitious formal and structural agenda, the project re-frames the perception of social housing. It shows that tight budgets for social housing do not have to lead to architecture of formal repetition. The project shows the potential of experimentation especially in social housing. It produces a recognizable identity, a memorable expression – qualities hitherto more willingly associated with architecture heighted by a larger budget. Claiming architecture of formal and material idiosyncrasy for a social housing project, the authors demonstrate how public housing can escape its historical clichés and start to explore an entirely new territory of potential.
