在很長的一段時間里，位于烏特勒支的Westraven辦公樓如同一個笨重、封閉、古板的巨人一樣，等待著被拆除。然而，市政當局選擇了對其進行翻新，翻新后的大樓至少必須體現其使用者——基礎設施與環境部的現代價值觀：開放、透明、專業和可持續性。cepezed提出的方案最能滿足這些要求。這座面積超過27,000平方米的大廈被拆到只剩下混凝土骨架，并留下了五個巨大空間，保證充足的自然光照，既能讓這座建筑給人予寬敞的感覺，同時又有良好的方位朝向。為了使外面的風景一覽無余，并讓充足的日光照入大樓，新立面大部分都裝上了玻璃。開放式構件讓自然通風成為可能。主要以特氟龍涂層玻璃纖維膜制成的雙重立面能夠擋風遮陽，保持完整的視野，并構成一種充分實現水平銜接的美學元素。

改造后的氣候系統主要由混凝土樓板擱柵之間的項目特定氣候天花板組成。大樓底部的一個23,000平方米的擴建區域內設有五個三角形辦公側樓，讓眾人能夠飽覽附近運河的美麗景色。三角形底部通過一條有效的交通干線相連，各個圓角連有一個大型全方位溫室，側樓之間的空間設有透明屋頂。建筑綜合體四周被一個觀賞池圍住，穩固地矗立在一個占地面積約3,000 平方米、彷如公園的環境中。

這座建筑很多方面都體現了可持續性理念。除了上述雙重立面和氣候天花板以外，還包括地熱泵、新建筑樓板內的混凝土芯活性、按用途劃分各種氣候區的布局，以及一系列綜合設計方案等元素，這些元素不僅美觀實用，而且大大節省了材料。

Westraven因其可持續性理念和建筑風格而獲得了眾多提名和獎項。此外，荷蘭建筑界的許多重量級人物也曾將該項目稱之為近年來最成功的項目之一。荷蘭建筑業協會（Bouwend Nederland）前主席Eelco Brinkman說：“無論在地理位置、舒適感還是能耗方面，所有東西都恰到好處。這樣的項目證明質量是至關重要的?！?/p>

For a long time, the Westraven office building in Utrecht was a heavy, closed and stuffy colossus that was due to be demolished. The revitalization that was nevertheless chosen had to at least reflect the modern values of the user, the Ministry of Infrastructure and the Environment: openness, transparency, professionalism and sustainability. The proposals made by cepezed matched the requirements best. The more than 27,000 m2 tower was stripped back to the concrete skeleton and provided with five enormous voids that bring a generous incidence of natural light and a feeling of spaciousness to the building and also contribute to good orientation. To create a panoramic view and allow a lavish amount of daylight to enter, the new fa?ades are glazed for the most part. Elements that can be opened make natural ventilation possible. A double fa?ade primarily of Teflon-coated glass-fibre membrane prevents wind nuisance, functions as a sunscreen that leaves the view intact and also forms an aesthetic component that generates strong horizontal articulation.

The renewed climate system consists mainly of projectspecific climate ceilings between the concrete floor joists. A 23,000 m2extension at the foot consists of five triangular office wings that offer as many people as possible a view of the adjacent canal. The triangles are connected at the base by an efficient circulation artery and at the rounded corners by a large, all-round conservatory where the spaces between the wings have been roofed over transparently. With an ornamental pond on all sides, the complex is firmly anchored in park-like surroundings covering an area of around 3,000 m2.

The ensemble is characterized by a large variety of sustainability aspects. Besides the double fa?ade already mentioned and climate ceilings, these include elements such as a geothermal pump, concrete core activation in the new-build floors, a lay-out divided into various climate zones related to use and a series of integrated design solutions, which are not only aesthetically pleasing and functional but also save considerably on materials.

Westraven has received many nominations and awards for sustainability and also for its architecture. In addition, various heavyweights from the Dutch construction world have described the project as one of the most successful in recent years. The former chairman of the construction trade association Bouwend Nederland, Eelco Brinkman, said: ‘Everything is just right: the location, the comfort, the energy consumption. A project like this demonstrates that quality is worth it.’
