This was my proposal on a sustainable design project at third year level of study

1. Sustainable
Design
LOCAL CASE
STUDY:-
Students’ Centre,
Management Science
Building & Business
School Building.

2. Climatic Responses and Sustainable
Design Concepts
Orientation andVentilation:-
• The MSB covers 4,570 square metres and
has four storeys and a basement.The
main building mass is oriented in the
North-South direction presenting
minimal direct solar radiation onto the
building façade.

3. • Another feature of the building is
extensive use of natural ventilation
through windows which can be opened.
The roof is a slab structure with a
coating of polyethene and tar, with a
polished aluminium top foil finish to
maximize the reflectivity of solar
radiation and thus minimize heat gain
on the slab.

4. • The building features a dramatic Atrium.
• The building also features an
auditorium, chapel, dining area with a
lounge and a spill-out balcony, library
completely fitted with indoor air quality
designed to meet LEED standards with
optimum relative air changes controlled
using evaporative cooling air units
situated at the top of the building.

5. ShadingTechniques:-
• The Western façade of the building
is shaded by a neighboring
building while the Eastern side has
roof overhangs and set in windows
which permit minimal solar
radiation into the building.

6.  Energy Efficiency:-
• The main source of energy is
electricity from the solar PV
system installed on the rooftop.
The building is also supplied by
the national grid for emergency
back ups

7. • The building has Building Management Systems
integrated into it to control the resource
utilization. User defined control-programming
was used to define the functioning of the various
components such as motion detectors, power
cards and lighting control.
• Provisions have been made for evaporative
cooling ducting in the whole building.The
systems have however only been deployed at
the basement due to the sufficient natural
ventilation and high indoor air quality in the
other spaces in the building.

8. • Lighting control system is directly affected by
the building envelope designs.The system uses
room orientation and time of day to disable
lighting fixtures that are close to the windows
when sufficient natural lighting is available. It
also disables all lighting in individual rooms when
the motion detectors indicate that the area has
been vacated.
• Use of energy efficient fluorescent tube lighting
with electronic ballast adds to the host of other
energy saving measures employed in the design.

9.  Water- Efficiency:-
• Rainwater from the building roof is
harvested into underground water
storage tanks where it is treated before
being pumped to the various water taps
in the building. An estimated 90% of
water needs for the building are met
using the harvested rain water.

10. Material andTechnology:-
• The MSB lay out and foundations were
constructed using well shaped stone with no
exterior finish.Curtain-walling was carried out
using 12mm clear glass.The windows are
aluminium framed fitted with 6mm clear glass.
The entire floor is of porcelain and ceramic tiles
while the interior is of cement and plaster finish.
• The windows are made of aluminium frame and
6mm clear glass panels.They are set into the
wall to provide further shading by the walls and
roof overhang. Integration of day lighting into
the building has been achieved through use of
12mm clear glass curtain walling system.
