The demand for qualified energy consultants with specialized expertise is steadily increasing. To work as an energy consultant, a complex examination must be passed. This textbook offers architects, engineers, and future energy consultants a compact collection of exam questions, divided into the sections of residential buildings and non-residential buildings. The questions provide a cross-section of the topic without delving into all the details. In addition to the amendment to the Energy Saving Ordinance (EnEV 2014) adopted in October 2013, this edition also takes into account the revised EU Energy Performance of Buildings Directive (EPBD 2010), the changes to the Renewable Energy Heat Act (EEWärmeG 2011), as well as the new edition of DIN V 18599 from December 2011.
