Abstract
Globally, the rate at which buildings use resources and energy has been rising. Due to
population growth, rise in living standard, and global warming, strategies for energy
conservation have been adopted lately in zero energy buildings. Over the past decade, the energy
consumption in constructions has increased at an unprecedented rate. Therefore, it is of great
importance to mandate energy rationalization in building construction. This research investigates
the impact of applying zero energy concept in homes in Egypt. The study begins by analysing
the current situation of the energy sector and existing buildings in Egypt, the NZEB concept is
defined and its different aspects are highlighted. Energy simulation by DesignBuilder simulation
software is used to evaluate energy performance for a residential single family house model after
applying Passive and Active design strategies. A number of energy saving strategies have been
examined to optimize the building envelope with minimum energy requirements. The building
energy consumption was reduced when various energy efficient strategies were combined.
Besides utilizing energy efficient HVAC systems . a solar PV system is installed to meet the
reduced energy. The case study was transformed into a zero-energy house. Results show that
passive and active techniques can be dependable for steady energy production in buildings in
hot dry regions.
