The risks of an energy efficiency policy for buildings based solely on the consumption evaluation of final energy

摘要: Abstract The concept of energy efficiency is addressed in a way that identifies the risks policies based strictly on assessment transformation final into useful energy. Considerations only technologies employed uses may generate distortions identification options truly preserve natural resources and minimize environmental impacts, especially when different sources are used as primary inputs. Herein, impact approaches discussed through case study regulations for buildings. selection approach relevant, with regard to comparative analysis between use electricity other sources, such fuel gases and/or renewable encourage anchored exclusively simplified identified four countries: Brazil, China, India Russia. In addition, this work estimates change average generation sector these countries over period from 1980 2008, demonstrating consumption should guide efficiency.
