Sustainable Passive System
In Egypt, the most frequently used type of energy is in thermal form. Notably, heating
demand merely takes 1% of the whole energy demand, while cooling demand reaches
up to 62%. To solve the high cooling demand, we devised a passive design using natural
ventilation, passive thermal control, and shading to control heat release.
Walls and Slabs are going to be thermal mass, elongating time for the heat to enter into
the building.
The roof stone panels block direct sunlight, and pyramid-shaped upper part and inverted
pyramid shaped-bottom part of the ceilings control indirect sunlight. The whole upper
part of Observatory Tower is open for heat release, and the middle façade has louver to
control sunlight.
Considering Egyptian climate, the water is scarce and therefore evaporative cooling is
not suitable. Radiant cooling and heating system is adopted instead for indoor floors. In
facilities with many people such as the planetarium have liquid desiccant system
operated by electricity.
The ventilation system makes use of the prevailing wind (North and Northwesterly
wind) going through the wide aisle connecting underground to the core area. Electricity
for side areas is made by winds and PV on parking lot roof.
Museology
Science has so many diverse branches that we can solve the following questions
scientifically. «Why are people born differently?», «How do l exist here?», «How are
the machines made that we use every day?», «What will happen in Space far out there,
and in the future?» When telling an endless
