零耗能一直是建筑可持续发展的话题之一，即将在2015年米兰设计周上展出的零耗能家具想必有许多环保人士关注。

能源能被存储在家具中。Raphaël Ménard和Jean-Sébastien Lagrange设计的零能耗家具系列中的第一张桌子，节约了大约60%的办公室供热要求和30%的空调需求。换句话说，这种家具就像保温海绵：它像空调一样吸收过剩热量（22度以上），暂时的过热后又存储热量，充当供热作用。奥秘在哪？就是桌子实木表面和下部阳极氧化铝之间的相变材料。

Energy can now be conserved through furniture. The first table in the Zero Energy Furniture range, designed by Raphaël Ménard and Jean-Sébastien Lagrange, enables almost 60% of an office’s heating requirements and 30% of its air-conditioning needs to be economised! In other words, this furniture acts like a thermal sponge: it absorbs excess heat (above 22 degrees), acting as air-conditioning, then restores the heat after this temporary overheating, therefore playing the role of heating. What’s the secret? Materials with phase change materials (PCM) between its solid wood surface and its anodised aluminium underside。

相变材料在室内温度开始过剩时，存储潜在的热量。相变材料中石蜡的熔点是22°C（‘固体’和‘液体’间的转变温度），并且它从周围空气中吸收热量，以限制室内气温过热。相变材料在小的体积内存储大量热能。

瓦楞状的铝片（一种非常好的热导体）促进房间和安置在桌面里的相变材料之间的热交换。这种轻型铝薄片皱褶还提供了卓越的结构稳固性和相当好的抗阻力。桌面因此能有非常大的跨距，支承点间有相当大的宽度。

这张气候调节桌是Z.E.F.（零能耗家具）项目的第一阶段。Raphaël Ménard和Jean-Sébastien Lagrange的这次协作研究项目，旨在提供能够为用户理解的轻型灵活物件和设备，以最大化气候调控和家用能源的效能。这是设计和工程间互动的成果，既实现了室内舒适的气候，又追求理性优雅的艺术感染力。

气候桌会在即将到来的米兰设计周上在VIA展台展出，这次展出是米兰，安萨尔多，伯格诺尼大道（angolo via Tortona）设计中心法国设计展的一部分。

The PCMs store latent heat when the inside temperature starts to become excessive. PCM wax has a melting-point of 22°C (the transitional temperature between ‘solid’ and ‘liquid’) and it begins to absorb heat from the ambient air by limiting overheating of the indoor climate. PCMs also store a large quantity of thermal energy within a small volume.

The corrugated form of the aluminium (a very good thermal conductor) encourages thermal exchange between the room and the PCMs situated within the table top. The folds comprising this light aluminium sheet also provide excellent structural rigidity and considerable resistance. The table top can thus have a very large span, a sizeable width between the bearing points.

This climate table comprises the first stage in the Z.E.F (Zero Energy Furniture) programme. This collaborative research project between Raphaël Ménard and Jean-Sébastien Lagrange, aims to offer light and flexible objects and devices that are understandable by the user to maximise behaviour regarding climate and home energy performance. It is the fruit of an exchange halfway between design and engineering, combining climatic comfort and a quest for rational and elegant aesthetic appeal.

The climate table will be presented during the forthcoming Milan Furniture Fair on VIA stand as part of the France Design exhibition at the Design Center – Ex Ansaldo – Via Bergognone 34 (angolo via Tortona), Milan.
