TABLE OF CONTENT

SOLARIS is state-of-the-art facility that forms an integral part of the renowned
Fusionnopolis clusters based on the design of Eco-Green mindset with a goal to be
certified BCA GREEN MARK PLATINUM which is the highest green certification
given by the benchmark of Singapore's Sustainable building. It is a 15 story multi-
tenanted structure with has the main function for infocommunicatinons, media,
science, research and clean-tech development at One-North. The overall energy
consumption for this building is the local precedents consumption with the reduction
of 36% which leads to the winning project in JTC competition. In addition, it also
introduces plantation that exceeds by 113% from original area site that is 8,000 m2 of
landscaping.

Singapore is located on the southern tip of the Malaysia Peninsula in Southeast Asia,
between the Indian Ocean and the South China Sea. Singapore lies on north of the
Equator near Latitude 1.3667ºN and Longitude 103.8ºE. Singapore features a hot,
wet climate and tropical rainforests.
Singapore's climate is divided into two different seasons, which are the Northeast
Monsoon, and the Southeast Monsoon season. These two seasons are separated by
two short inter-monsoon periods.
Figure 12: Average Daily Maximum and minimum temperature ºC chart
The minimum temperature in Singapore is ranged 23ºc to 26ºc and maximum
temperature ranged 25ºc to 31ºc throughout the year. From the chart, January and
December are the coolest month throughout the year.

Relative humidity in Singapore is in the range of 70% -82% throughout the year.
Singapore is a country where it has high level of humidity. It differs from 82% in the
morning and falls to 60% in the afternoon, when it is not raining.
Figure 15: Wet Days chart
Singapore is located on the equator, thus the country experiences rainfall throughout
the year. As mention in the introduction, Singapore climate is divided into two
seasons, which is;
A) Northeast Monsoon; which happens on the period of December to March. From
the chart, December and January achieved the highest value, which labeled as "wet
phase" while February and March has lower value that is labeled as "dry phase"
B) Southwest Monsoon; which happens on the period of June to September. From the
chart, this period has average number of wet days that usually last for most 2 hours.

Wind Analysis

Wind Arrow of Singapore
From the wind arrow chart, we can conclude that there is always strong wind
at the direction north-east while weaker wind at the direction south-east. The darker
blue represent longer hours, while lighter blue represent shorter hour.

Psychrometric Chart of Malaysia (same as Singapore)
From the chart above, we can conclude that to achieve thermal comfort, the
temperature and humidity of the place or area should reach within the yellow box
value showed above. The values inside the box stat that with the range of temperature
from 23 degree Celsius to 27 degree Celsius and the humidity value from 4 to 13 is
the thermal comfort zone. With the present data, a green building should have the
ability to maintain as a thermal comfort zone.
Psychrometric Chart

Throughout this case study, seven (7) passive design features are pointed out from the
Solaris, Singapore. Seven passive designs are:
I. Spiral Ramp Design
The key architecture element would be the undisturbed ecological 1.5km long
perimeter landscape Spiral Ramp and Eco-cell at the basement for fluid movement of
organisms and plants within the building contributing to the overall health of these
ecosystem which will provide an enhancement of biodiversity. With its deep
overhangs and large concentrated of vegetations, represents a key element in
comprehensive strategy for providing the cooling effect in the building facade. This
provides an interactive environment for the worker with the nature while still sustain
the inorganic form of the structure with a more organic mass. In addition, Solaris is
trying to enhance the existing ecosystem instead of replacing them.

II. Naturally Ventilated Spaces
During the hot days, Computational Fluid Dynamics (CFD) is stimulated through the
atrium led to the actuated skylight louver system that allows stacking ventilation
effect. Through the principle of hot air rise and cool air falls, hot air escape from the
top of the roof while cool air are being to pull into the building form the lower floor.
III. Skylight / Actuated Smoke Vent Louvers
Besides allowing the natural light to enter, skylight also serves as another purpose
besides the stacking effect. It is also consider as a fail-safe system. When fire is
detected (via the building's intelligent management system), the skylight louvers will
automatically open and became an exit for the smoke or harmful gas. For safety
reason, the louvers will automatically opened even without power supply. With this
system, smoke control system is being eliminates which leads to saving cost and
power. For extra purposes, it is also a weather shield such as rain by rain detection
sensors and direct sunray.

IV. Rainwater Harvesting System
This building is equip rainwater recycling system which rainwater are collected using
siphonic drainage systems then stored beneath the Eco-Cell in the primary holding
tank and a small transfer tank on the roof. This building has an integrated fertigation
system that able to maintain the organic nutrient level in the entire building through
the vegetation cycle from the combined storage that has a capacity of over 400m3.

V. Climatic Responsive Facade System
According to local sun path analysis that sun rise from east in the morning and fall on
the west during evening, sunshade louvers has been designed to screen off direct glare
and heat from the sun yet allow a gentle light to enter to the interior space. This help
to minimize the usage artificial light during daytime. The solar shading also helps to
reduce the heat transfer into the building.

VI. Planter Box Design on Landscaped Spiral Ramp
The spiral ramp has a minimum width of 3m of landscape. Maintenance of the ramp
is achieved through a parallel pathway that allows for servicing the planters. It is also
design to serve as a linear park that stretches all the way from the ground plane to the
upper roof. The planter boxes on the spiral ramp are being designed to be as shallow
as possible so that the building facade is being kept and reduce its bulkiness. Plants
are being carefully selected based on their roots structure because of the lacking of
deep soil. An elaborate network of drainage trenches and subsoil pipes is to ensure
water is evenly discharge in the 800mm planter boxes even when there is a heavy
downpour. This step is very important as the landscaped ramp is steeply inclined and
rainwater would cascade down at high speed on the surface level if it were not being
absorbed by the soil.

VII. Roof Gardens and Corner Sky Terraces
This area creates a vertical landscaping which acts as a thermal buffer that provides
events, relaxation and social activities. In addition, it allows an opportunity for
interaction between the people and nature. It is also a good symbol for sky rise
greenery design building because it has a total of 95% of landscape is above ground
level.
Figure 24: Roof garden
By doing so, beam sunlight will not strike into the building directly. Also, energy
required for interior artificial lighting can be gradually reduced.

After some site visits to Sunway Pinnacle Office Tower, we found out that the
building is not fully completed for the wiring and electrician part. Due to that reason,
the building manager, Mr Kurma, can allow us to visit some part of the building.
Although we were limited from some spaces of the building, we still manage to
interview Mr Kurma. From what we were told, the building has a gold standard from
the Green Building for a reason. From the outside of the building, it doesn't look
much of a standout but when you reach the interior and take a closer look, the
building actually has the design and technology to support it as a green building. In
addition, this building is one of the first Green Building in Malaysia from what Mr
Kurma had said. From the visitation paid to the site, we get to know that this building
is a sub-branch from the main building at the side with an addition of Green
Technology apply into it. We were expecting the building to be done by the end of
last year 2013 but when we got there, it is only 95+% complete. Since then, we are
not allow to go up to experience the spaces on top. We suggested that they should
provide more shading effect from the main building to the new building because of
the weather in Malaysia. In addition, the ventilation for air is not as ventilated as we
thought and most of the lighting is not natural lighting but artificial lighting.
