3. 1.0 Project Brief
This project aims to provide an opportunity for students to propose an external device – Gizmo and at the same time, act as building façade.
The application of Gizmo helps to reduce energy consumption by controlling the sunlight penetration into the building and subsequently
reduce solar heat gain inside the building without compromising the Indoor Environment Quality (IEQ). Sufficient amount of wind also help
to achieve thermal comfort without the aid of mechanical ventilation. The following aspects should be taken into considerations;
• To establish a baseline analysis of the proposed building in Urban Design Studio in relation with the surrounding context to set a base
standard in order to have a clear comparison with the implemented gizmo proposals.
• To implement environmental sustainable strategies to achieve indoor thermal comfort using passive design.
• To simulate wind flow and daylight performance using Ecotect on a selected area to measure the efficiency of proposed Gizmo.
• To compare and analyze proposed Gizmo and conclude the best option in order to achieve indoor thermal comfort.

Site
Jalan Tengku Kelana
Royal town of Klang has been a place where many great
historical events took place where it can even dates back to
the prehistorically time which some of them still traceable
on site. Klang used to be the administrative quarter of
Selangor before the Shah Alam.
Klang town has been divided into 2 which are the northern
part of the Klang and Southern part of the Klang devided by
Klang river in between.
The southern Klang is the more older part of Klang with
very much celebrated Indian street along Jalan Tengku
Kelana.
As the time passes, people started to move away from the
Klang town to new township where more commercial
activity and happening.
The site (Jalan Stesen 1) is one of the oldest street in Klang,
located right next to the Klang KTM station. Many building
here are from the 60s and earlier.

The proposed site is located at
3.0427876°N, 101.4484464°E
Stereographic diagram on the left shows the movement of
the sun throughout the year. The position of the sun is
commonly represented by two angles – altitude and
azimuth. Architect always refer to stereographic diagram
and come up with a better building design in control sun’s
energy and heating into building.
21st June (Summer Solstice) – most sunlight of the year
21st December (Winter Solstice) – least sunlight of the year
Azimuth Lines - Azimuth angles run around the edge of the
diagram. It is the horizontal angle between the sun and
true North.
On 21st June
Sunrise: 66.48° (07:06:58 hour)
Sunset: 293.52° (19:24:56 hour)
On 21st December
Sunrise: 113.42° (07:13:39 hour)
Sunset: 246.57° (19:10:37 hour)
These two periods are the most critical period as the sun
will irradiate on the building North and South facades. This
allow different design strategies to be applied.

most frequent wind blowing from (732 hours) with wind speed of 1-5km/h. Stronger wind exceeding 5km/h has been recorded on North East with 157 hours
and wind speed exceeding 12km/h lasted for 25 hours throughout the year. However, south side recorded 129 hours of zero wind speed.

Wind Flow Factor Simulation from North East with 5m/s wind speed. (generated from Autodesk Ecotect Analysis and WinAir )
Monthly Wind Flow Direction
Site
The wind simulation is run on 3 metres from
ground level during August with wind speed
of 3.33m/s. It shows how the buildings
surrounding the site affect the wind direction
and magnitude.
As shown in Figure, Site 1 barely has any
wind factor compared to Site 2 which
benefits from the August higher wind speed
and lesser obstruction from site while Site 1
is blocked on all sides.

Wind Comfort – Beaufort Scale
(Source: https://www.iawe.org)
Figure shows the wind comfort scale that indicates the wind effects caused on human at different range of wind speeds. The most
desirable wind speed for human comfort is from 1.6 -3.3m/s as studied by Francis Beaufort. According to Malaysia climate analysis, the
average wind speed is 1.8m/s, which falls under the comfort level of this scale.

28. 6.0 Conclusion
Gizmo proposal 1 and 2 are combined to generate Gizmo Proposal X due to better ventilation. The studio selected for simulation is a dance
studio where activities inside require movement and sweat. Gizmo that allow best ventilation into the building helps to cross ventilate and
cool down the temperature in the building and at the same time removing the scent in it.
From simulation, all proposed gizmo outcome of Lighting Analysis doesn’t have much difference as it is a long façade with big opening facing
towards Northeast and Northwest. The space receive sunlight throughout the day which causing the room to be slightly above benchmark
but its still in the range of tolerable. With the additional mechanical ventilation would further lower down the day lighting factors to achieve
thermal comfort.
Further suggestion, controllable or adjustable louvers would perform better as it can always be adjust according to the users’ comfort.
Different way of rotating forms different pattern to the façade which creates interesting and responsive design.
