Zero Energy Furniture by Raphaël Ménard and Jean-Sébastien Lagrange


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. tablclimshéma_en

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.
Raphaël Ménard is an engineer graduate from Ecole Polytechnique, a Ponts et Chaussées civil engineer, as well as an architect (DPLG). In 2003 he founded and now directs Elioth within the Egis group. He won the Next Gen prize awarded by Metropolis in 2009 for the project Wind-it. He is also an associate teacher in the framework of the Post-Carbon Architecture DPEA at ENSAVT. www.elioth.com
Jean-Sébastien Lagrange is a design graduate from Ecole Boulle and from ENSCI – Les Ateliers. He set up his own agency and works with different manufacturers and institutions (Manufacture Nationale de Sèvres, Ministry of Culture …). He was an Agora grant finalist in 2013 and 2009 as well as for the Audi Talents Awards in 2011. www.jslagrange.com
