ENVIRONMENTAL PROFILE

The use of American cherry and maple in the Invisible Store of Happiness combined with strong craftsmanship emphasising efficient material and energy use contributes to a very strong environmental profile. Both cherry and maple are highly desirable timbers which are readily available in the U.S. forest but which have been underutilised in recent years. It takes less than 15 seconds for new growth in the U.S. forest to replace the hardwood logs harvested to manufacture the Invisible Store. The carbon footprint of the structure is 36 kg CO2 equivalent on a cradle to grave basis, less than half that of an Apple iPhone1. Much of the energy input into material production derives from renewables. The waste wood produced during manufacturing and at End Of Life can be used for energy production, thereby offsetting use of fossil fuels.

Of course it would be a shame for such workmanship to be sent to the incinerator too soon. Such an outcome seems unlikely – the structure is designed to be readily dismantled and transported elsewhere. Its first stop will be 100% Design (23-26 September 2015) during the London Design Festival. This fact, together with the quality, beauty and durability of the design, suggest the Invisible Store will remain on display and act as a carbon store for many years. Around 825 kg CO2 equivalent is sequestered in the Invisible Store of Happiness.
