Invented in 2009 , the BSB achieves high energy efficiency and carbon reduction primarily through thermal insulation , preventing cool air from leaving indoors and hot air from coming in from outdoors when the weather is hot and vice versa when the weather is cold , and requires short construction time since parts are pre-fabricated in factories and assembled onsite . At the 2010 United Nations Climate Change Conference , President of Mexico , Felipe Calderón , called the BSB technology " a practical , imaginative , creative & bold endeavor '' and '' a new revolution of world 's architectural and housing industry " , which is bound to be transferred to developing countries leading to reduction in carbon emissions . BSB has also been tested to be able to resist a 9.0 magnitude earthquake and was recommended in a United Nations Environment Program report on the rebuilding of Sichuan after its catastrophic earthquake in 2008
