CONCLUSION AND COMMENTS
As per the previous overview, there are several observations as following:
- Monitoring and simulation are often used in the researches that aim at improving thermal comfort and energy efficiency in different regions. Meanwhile, simulation and discussion are used in case of learning environmental principles from historical buildings.
- Researches that discuss historic houses in hot zones are mainly concentrated in Iran.
- In Egypt, there are some recent researches that have analysed Ottoman houses from green architecture perspective using simulation method.
- The majority of researches, that deal with the energy performance in historic buildings focus on cold climate such as different parts in Europe. The reason behind that, is that the EU published a policy to reduce the energy consumption by 2050. That is why public policy is an important step to encourage the researches in that field.
- The conservation of Cairene houses mainly focuses on the physical characteristics (such as material) with less attention to the reuse goal.
- Dealing with environmental issues is only limited in adding insulation to stop water leakage inside the building.
RESEARCH METHODOLOGY OF THE PHD (GENERAL and DETAILED)
GENERAL METHODOLOGY "Concept"
The PhD topic deals with the following aspects, as shown in (Figure 24): A
- Analysis of Climate Conditions in Cairo.
- Analysis of building model “house” of Ottoman period.
- Analysis of actual thermal comfort level.
- Results (of the previous step) will be compared according to international & national standards with respect the (re) use requirements.
- Analysis of thermal comfort level with several suggested criteria for retrofitting with respect the conservation requirements.
In Appendix 2: There are description of climate conditions in Cairo and primary studies of the thermal comfort inside a simple model from limestone masonry. This model is a first step for testing thermal comfort inside Cairene houses. The aim of this model is to address the main factors that affect the thermal comfort level in these buildings.
