These pictures show SUPERTHERM ® tinted to yellow with a trim color of gray to coat the exterior of apartment buildings. Munich like Vancouver is primarily a heating climate as opposed to a cooling climate. The interest was more for holding heat inside the building during winter. Reported savings during the winter time is 20% due specifically to the SUPERTHERM ® coated walls on the exterior. Coating the interior side of the building envelope ( walls and ceiling ) would have been the most effective application however the renters did not want anyone painting inside their units. Consequently, the interior walls were allowed to absorb the convective and radiant heat. This heat then conducted to the exterior where it was still repelled back by the multi~ceramic technology in SUPERTHERM ®. As a further benefit, these units in this unconditioned apartment building are also much cooler in the summer and also greatly reduce the " HEAT ISLAND EFFECT ".
