Operation of Energy Efficient Residential Buildings Under Indoor Environmental Quality Requirements

This paper is devoted to the influence of Indoor Environmental Quality, [IEQ] requirements associated with occupation regimes on the criterion of energy demand s for HVAC (Heating, Ventilating and Air-Conditioning) central systems that were constructed for student hostels as a residential building in Cairo, Egypt. The paper focuses on the effects of occupation rate profiles with IEQ thermal parameters; (those are air dry-bulb temperatures, relative humidity, fresh air requirements, and local air velocities), on yearly energy demands. It is applied on, in-service, real project as a case study "10-Stories Hostel of 6000 m2 built-up area" that is utilized by Non-Local students as a transferred Egyptian citizens [ EC ] from different governorates. It was concluded that. during energy simulation, occupation rate schedules and operation profiles for each source of heat inside space shall simulate the reality. These profiles and schedules should be added to the local energy code as a guideline for designers. Although in this case study results from simulation task reach the real bills, but sometimes, with multi-use apartments there is another required schedule for the Pre-Action days. Those days before holidays and feasts on which the air conditioning system shall operate in a certain procedure for cleaning or scavenging. Another important issue is the effect of Effective Temperatures [ET] (Temperature for constant thermal sensations) that could implement to reduce the cooling capacity by increasing the room temperature against indoor relative humidity for the same comfort sensation. These two concepts will save 17% to 22% of the project total energy demand, In addition to introducing new design criteria for acceptable indoor conditions in the new rural developed zones in Egypt and similar regions.
