PCM-enhanced table selected for French accelerator program

Ben Welter - Friday, June 09, 2017

Table ClimatiqueA table designed to reduce energy costs by absorbing heat when indoor temperatures rise above a comfortable level is among 25 innovations chosen for FAIRE Paris, an accelerator program supporting "innovative urban design and architecture projects" in France. 

"Table Climatique," designed by Jean-Sébastien Lagrange and Raphaël Ménard, contains microencapsulated Micronal phase change material within triangular folds of lightweight anodized aluminum. The PCM has a melting point of 22º Celsius. It releases heat when temperatures fall below a comfortable level.

"The waved geometry of the conductive aluminum fosters thermal exchanges between the room and the PCMs located inside the Climatic Table," according to the creators' website. "The folds of the light-weight sheet of aluminum give also an excellent structural rigidity and carrying strength. Thus, the plateau might have a very large span."

Ménard and Lagrange hope to develop a line of "zero energy furniture" products based on the table.

PCM-powered table is featured in Milan Design Week showcase

Ben Welter - Thursday, April 16, 2015

PCM tablePhase change material is on display at Milan Design Week. But you'd have to look carefully to find it. A table designed by Jean-Sébastien Lagrange and Raphaël Ménard contains PCMs within triangular folds of anodized aluminum. Photographer Amandine Dowle lists the table among her favorite green furnishings at the Designerblock showcase.

The prototype is designed to reduce energy costs buy absorbing heat when temperatures rise above a comfortable level and releasing heat when temperatures fall below that level. 

April 20, 2015, update: Ménard, responding to an e-mail inquiry, said the folds are filled with BASF's microencapsulated Micronal PCM, with a melting point of 22º Celsius. Regarding retail plans, he wrote: "We are looking forward [to] large-scale development for [a] full range of products."
