The aim of this study is to evaluate the constructions quality in addition to the energy consumption at a residential sector in a cold region. Djelfa is a medium sized town located at the centre of Algeria and characterized by cold climate for more than six months a year and high seasonal temperature variation. Consequently, citizens must adapt their constructions depending to this hostile climate. During the period 2013-2017, MNO (Meteorological National Office) data at Djelfa station revealed

Considered buildings are two standards housings: HEP housing (High Energy Performance) and an ordinary housing, both buildings have the same architectural context. Obtained results from real measurements demonstrate that only 1.3 % increase is recorded in the gas consumption for ordinary housing compared to HEP. While the computation based on the Algerian thermal regulatory show that the HEP can save up to 48 % of heating energy compared to ordinary housing, which is different to real measurements. Besides, the difference in electricity consumption is 35 % saving in favour of the HEP due to the use of economical instruments. Finally, several propositions such as; the use of solar panels, trompe wall can be investigated in order to obtain more performed buildings in terms of energy.
