reflection on marathons



after running the half-marathon of Brussels in 1:38h, Marco Zaccara of 2012Architects collects 50m2 of thermal insulation trashed by runners. The foil can be used to improve existing insulation or make a radiation refelector below a floor or behind your plasterboeard wall. two layers with a 2 cm space inbetween does a great deal. Some commercial suppliers like offer similair foils. The total estimate of insulation foil from the Brussels marathon is about 5000m2, enough to give 10 small houses a thermal reflector and save a lot of energy.
