PREVAILING WINDS OF ALEXANDRIA• As shown in the windrose
diagram, the prevailing winds of
Alexandria is like the most of
Egypt , coming from north and
the western north
• This is essential to be used in the
design to direct the building
façade to receive more from the
pleasant air from the northern
/western sides
• As the weather in Alexandria
follows the Mediterranean
weather that is most likely warm
and humid ,also the temperature
difference is small compared to
other places in Egypt that follows
the desert weather , its necessary
to use the following strategies
while designing a building in
Alexandria
1. To use the natural ventilation
when possible to cool /warm the
interior spaces
2. To maintain the building
envelope tight and weather
proof to preserve the
mechanically conditioned spaces
when needed to drop humidity
or heat in the too cool
conditions

6. PSYCHROMETRIC CHART
• This chart shows the comfort
range of Alexandria city including
temperature / Humidity
• Passive design strategies are the
ones that are put into the building
once by design. Without the help
of increasing energy demand of
the building in cooling/heating
• The small polygon shows the level
of comfort that is already there
without adding passive design
strategies to the Building
• By adding the passive design
strategies as (natural ventilation
/thermal mass we see that the
comfort range of the building has
increased to cover a wider range
throughout the year
RAWAD ELDAHSHOURY 2018

7. DESIGN STRATEGIES
Receive more air getting into the building
to reduce the energy demand in heating
/cooling by introducing air through more
operable openings and yet easily
controlled when needed
Produce the design with more free
corridors with no obstacles that
reduce air speed
Preserve the heat /or cooled air by
tighten up the openings with
controllable hinged windows /doors
Study the façade carefully and to
insulate the necessary walls to resist
heat gain by the sun
Reduce concrete mass by constructing
roof with light insulated structure
(MARMOX)
Shading what’s left from façade by
trees /self shading/or neighbor
buildings
OPEN SHADED COURT DESIGN CHANGES WALL TYPES
SHADING STUDIES THERMAL PERFORMANCE VEGETATION
RAWAD ELDAHSHOURY 2018

8. DESIGN CHANGES
• Insulate all exposed floors in top
level and open corridors to avoid
thermal transfer into the lower
spaces
• Insulate all exposed floors in top
level and open corridors to avoid
thermal transfer into the lower
spaces
• Wall insulation should be
studied carefully to avoid
over insulation that could
affect the building
negatively by containing
unpleasant temperatures
for longer periods
RAWAD ELDAHSHOURY 2018

9. • The court inside the Building provide fresh air getting into spaces
and allows hot air to escape through the atmosphere
• Shading the court and creates a positive pressure cooled area that
drives the air into the inner spaces
• By adding long trees inside court it will give the desired effect and
pleasant feeling to the building users

12. OPTIMIZING THE FAÇADE ACCORDING TO DAYLIGHT
• Exterior walls have different insulations according to the
wall location /conditions
• Windows shading is not included in the calculations due to
software limitations , therefore the calculations presented
are showing improvement without shading . As known
limiting glass exposure to sunlight are crucial even if it’s
not computed
• Areas of larger window to wall ration (glass house ,etc.)
have separate insulation to limit the effect on the entire
building
• Roof material is high efficient insulation (proposed
Marmox board or any other light insulated structure

• Default walls 20 and 10 cm with mortar and plaster
• Windows as designed have no shading
• The areas that has a large exposed glass (bigger window to
wall ratio) are left without insulation
• Materials of the roof is default insulation and fairly light
paints
• Exterior wall s have different insulations according to the
wall location /conditions
• Window shading is not included in the calculations during
