“As a group, we constantly push the frontier of
infrastructural and architectural design trends
to meet the needs of modern facilities and
their usage. Thus, one of our most distinctive
design niches is environmentalism. The team is
concerned and mindful of the impact modern
infrastructure can have on the environment and
we are hence, constantly producing solutions
that enable us to co-exist with nature in
harmony.“
CPG Consultants, Green Approach
Introduction
Nanyang Technological University is one of
the largest public universities in Singapore
which boasts a 200 hectare campus. Each
school has their own building on the
campus ground. One of the new building
inside the campus ground was built for
its School of Art, Design and Media. The
building is a green building designed and
built by CPG consultants which caters
to the environment by means of passive
design relative to the tropical climate and
is recognised by Singapore’s Green Mark
System (Davis, 2012).
Climate
Climatically both Singapore and Malaysia
are a hot and humid country; Singapore, a
city-state, lies 1° north of the equator. This
essentially contributes to it having a tropical
rain forest climate along with its maritime
exposure. Due to the country being
Nanyang Technological
University’s School of Art, Design and
Media achieved the Green Mark Platinum
Award (refer to Image 3) from the
Building and Construction Authority for
adopting best practices in environmental
sustainability (Green Mark).
Green Certification
surrounded by water, its temperature has
minimal fluctuations, negating the four
seasons (Bruno, 2011).

This unique building is situated in Singapore, specifically in the 200-hectare Yun-
nan campus, adjacent to the Jurong West district of Singapore. It is situated at
a crossroad between Nanyang Avenue and Lien Ying Chow Drive and is flanked
by the Simtech Valley Block. The building is used mostly during the day when
the students and staffs occupy it and is left empty during the night. It is spaced
apart from nearby buildings as it houses the School of Art, Design and Media.

NATURAL AND MAN MADE FACTORS
“ Components that affecting the comforbality of the building “
Dense voysiamatrella grass turf
The grass turf helps to absorb Singapore’s intense sun which
decreases the temperature of the air surrounding the university.
Moreover, thus eco-friendly attribute enhances the outdoor gathering
spaces of the university.

Exposed Facade
The facade of the building is an expansive curtain wall facades of
high-performance, double-glazed glass. It is longitudinally oriented
east-west and more north and south exposures.
The glass curtain walls maximizes interior daylight while minimizing
heat penetration. Double-glazed windows are windows with two
sheets of glass separated by an air tight gap. This creates an insulation
barrier and helps prevent heat loss in winter and heat gain in summer.
The combination of high insulation frame, twin compression seals
and double glazed units gives a level of thermal efficiency that is
unsurpassed. Double glazing is designed to minimize heat transfer.

Almond Shape Courtyard
The courtyard expands access to daylight and cooling effect. It
provides natural light into interior spaces as well as in providing cooling
properties from the water attributes exuding a serene environment and
emanating a refreshing breeze that cools the courtyard.

Raw Concrete Materials and Finishes
Concrete is high energy efficient. Its thermal mass or ability helps in
absorbing and retaining heat which helps in cutting heating and cooling
bills. Moreover, concrete’s reflectivity properties minimizes the affects
the produces urban heat island as it absorbs less heat and reflects
more solar radiation.

Curved Green Roof
The curved green roof that casts in heavily ribbed, reinforced concrete
which also forms the double curve layout
The green roof reduces solar gain and slows run off during Singapore’s
frequent downpour. The turfs are irrigated using rainwater collected in
the storage tank. Moisture retention materials are installed beneath the
soil helps keep the grass consistently damp that creates a surrounding
temperature that is not too hot. This helps in creating a thermal
environment that is comfortable for the occupants of the university.

Singapore’s climate is character-
ised by uniform temperature and pres-
sure, high humidity and abundant rainfall
because of its geographical location and
maritime exposure. Relative humidity is
in the range of 70% - 80%.
Buildings constructed in high humidity
locations need to have dehumidification
capability to avoid moisture build up
inside the building, causing discomfort
and moulds.
Humidity
	 Singapore maintains its tem-
perature throughout the year with little
changes between its maximum and
minimum temperature. The average
temperature is between 23 degrees
Celsius and 31 degrees Celsius. April
is the warmest month, January is
coolest month and November is the
wettest month.
	 In terms of building design,
exposed heavy construction materials
with low heat conductivity materials
is highly favourable such as concrete
which reduces heat gain into the build-
ing and store cooling energy.

Upon completion of our research,
we have found out that the consultants
took a lot of measures to design this
building in accordance with the natural
sun orientation as their idea were to
build an open space university (2014).
Referring to the site plan, this building is
located in the housing area with a
proper development from the
Singapore’s government. As it is
situated far from the main city, there is
no natural shading from the surrounding
building except for the location natural
vegetation. Thus, the consultants built
this building with a proper orientation
by placing the facades facing north
and south to minimize solar gain. After
achieving the right orientation for build-
ing, the facade is fixed with glass curtain
walls.
Benefits from Site Context
	 During our site visit, we felt
really comfortable when we were
inside the building and also in the
courtyard. According to D.K Ching,
taking advantage of the land or
ecology of the building is one way to
enhance green building’s factor. Thus,
the purpose of almond-shaped
courtyard in the middle of the
building is to provide natural lighting
into the interior. Next, the consultant
took advantage of the sun orientation
by designing a green roof. According
to Alwitra GMBH.co, the purpose of
the green roof is to bring out the
aesthetic value of the building from
other conventional multi - storey
buildings, in the campus and in the city
(2013). Moreover, the green roof
functions to cool the building
environment by absorbing Singapore’s
intense sun and slowing runoff during
Singapore’s downpour (2014).

date and time was set through the
analysis of Singapore’s season which
are North-East Monsoon Season,Pre
South-West Monsoon, South-West
Monsoon Season and Pre North-East
Monsoon. The consultant achieved their
intention to make use of the
building orientation, green roof and etc
to overcome the Singapore’s intense
sun. As the curtain glass wall is
orientated to the north and south, there
is no full exposure from the sun as it is
only direct to the courtyard. Next, since
the green roof is on top of the building, it
is fully exposed to every direction of the
sun to oppose the Sun heat.

WIND ANALYSIS
“The Ventilation”
Top

The courtyard of
Nanyang
Technological
University
The northeast monsoon season, from
December to the beginning of March,
is when north-easterly winds prevail.
Whereas, the southwest monsoon
season from June through September,
is when south-easterly or south-west-
erly winds blow. (Figure 5) Due to the
2 monsoon seasons and the location of
Nanyang Technology University which
is relatively near to the sea, the amount
and speed of wind flows are higher and
faster compared to the other months
and locations.(Image 27) For the
building itself, the verdant turfed roof
and the courtyard are the two spaces
that would be well ventilated.
( Image 29 ).
Sun Path Case Studies
The sliding doors and opened windows
are also allowed the air ventilation to
flow throughout the building. Winds
are incorporated onto the roof and also
the courtyard to allow students to feel
cooled. Moreover, the presence of wind
helps to lower down the temperature
outside while the majority of interiors
such as the counter area, halls, classes,
studios, admission centre, and so on are
ventilated by using air conditioners.
( Image 29 ). However, the air
conditioning are switched off after 11pm
every day. It is to be eco-friendly.For
Nanyang Technology University, the
wind flows helped to improve the
thermal comfort.

THERMAL ANALYSIS
“Comfortability”
When people are displeased with
their thermal environment, not only is it
a potential health hazard, it also impacts
on their ability to function effectively,
their happiness/satisfaction at work, the
likelihood they will remain a customer
and so on.
	 BS EN ISO 7730 defines thermal
comfort as ‘…that condition of mind
which expresses satisfaction with the
thermal environment. ie the condition
when someone is not feeling either too
hot or too cold.
	 The human thermal environment
is not straight forward and cannot be
stated in degrees. Nor can it be
reasonably be defined by adequate
temperature ranges. It is a personal
experience dependent on a countless
number of criteria and can be different
from one person to another within the
same space.
Thermal Comfort Analysis
For example, a person walking up stairs
in a cold environment whilst wearing a
coat might feel too hot, whilst someone
sat still in a shirt in the same environ-
ment might feel too cold.	
	 The Health and Safety Executive
propose that an environment can be
said to attain ‘reasonable comfort’ when
at least 80% of its dwellers are thermally
at ease. This means that thermal
comfort can be assessed simply by
surveying inhabitants to find out whether
they are unhappy with their thermal
environment.
	 At one degree above the equator,
the climate in Singapore is typically
tropical; hot and humid throughout the
year. The temperature usually lingers
around 30 degrees Celsius (86 degrees
Fahrenheit) with 75 per cent humidity.
Rainfall is slightly higher during the
winter with a monthly average of 260
millimeters (10 inches) and summer
months averaging 170 millimeters (six
and a half inches).

Enlivened by fountains, cascad-
ing water and a “floating” performance
platform, the reflecting pond of the
building’s interior courtyard both creates
ambience and cools a pleasant commu-
nal area in the center.
	 The main green feature of
the building still remains the iconic
curved green roof.
	 A living or green roof is a roof that
is substantially covered with vegetation.
These have positive effects on buildings
by reducing the stress on the roof sur-
face and increasing their life, improving
thermal comfort and reducing noise
transmission inside the building,
reducing the urban heat island effect,
reducing storm water runoff,
re-oxygenating the air and removing
airborne toxins, recycling nutrients, and
providing habitat for living organisms, all
of this while creating peaceful
environments. Therefore, green roofs do
have an immediate effect on the thermal
comfort of a building.
	 Indoor temperature reduces in
the buildings having green roofs with the
increasing of the soil thickness.( Image
31 ) There is a significant influence of
soil thicknesses in green roof for
improving the indoor temperatures in the
upper floors of buildings. However, soil
thickness does not effect on the indoor
temperature in the ground floor. The
latter is affected by the curvilinear plan
form of the building,creating an

opening in the center which hosts a
cooling courtyard. The green roof is
applied here on NTU, which has upper
floors, exposed to the direct sun light
throughout the day time as a passive
element. Studies and experiments car-
ried out by professionals have shown
that the indoor thermal performance of
a green roof is better than the traditional
roofs. As a reason of aging of buildings,
the absorptivity of traditional roof mate-
rials increase. However, in a well main-
tained green roof, this remains same as
newly constructed green roof.
	 The glass curtain wall is an-
other feature which adds on to the
thermal comfort of NTU.
	 Windows are complex and fas-
cinating elements in the material of
a building. They allow light and fresh
air and provide views that link interior
spaces with the outdoors. Unfortunately,
windows can be a maincause of un-
desirable heat gain in hot weather and
significant heat loss in cold weather.
	 Windows can have a severe
impact on the heating and cooling loads
of a building. Up to 40% of a building’s
heating energy can be lost and up to
87% of its heat gained through win-
dows. (http://www.yourhome.gov.au/
passive-design/glazing)
	 Improving windows’ thermal per-
formance reduces energy costs, green-
house gas emissions and improves

thermal comfort within.
	 Careful selection of window glaz-
ing greatly increases thermal comfort for
people near to windows, especially large
windows. The sense of comfort is not
just determined by air temperature: the
temperature of surrounding surfaces has
a great impact.
	
The goal should be to attain an inside
glass surface temperature as close as
possible to the preferred room air tem-
perature. This means glass that is nei-
ther cold in winter nor hot in summer.
	
	 Although we lacked the time to
do an in depth mathematical thermal
behavior room-by-room analysis/mea-
surement of the entire building, we did
get to measure the dry bulb temperature
from certain areas of the building, out-
side to inside the double glazed glassed
walls.

CONCEPT ANALYSIS
“The Conclusion of Our Analysis”
One of the main features of Nanyang Technological University that can be noticed is the exterior
glass curtain walling. It is utilizing passive solar design to help maximize natural lighting by using proper
orientation of the building and providing appropriate shading to reduce overheating.
	 The building is specifically orientated facing the north and south ( Picture 1 ). This is to minimize
the solar gain and heat load in the morning. The glass exterior facade allows natural views and sunlight
into the building, allowing visual exchange between indoor and outdoor spaces. This give an amazing
experience while being in the building and enjoying the surrounding at the same time.
	 The glasses are double-glazed to reduce heat penetration into the building, while allowing
maximum interior daylight to pass through ( Picture 2 ). It helps to reduce the temperature transfer
between exterior and interior spaces. Glass openings are also placed throughout the interior walls to
provide natural sunlight diffusing through each space. This allows continuity of lighting throughout the
building ( Picture 3 ).
	 Strategic window placements for rooms and toilets that are placed underground enhancenatural
lighting into the building. This allows sunlight to illuminate the spaces inside ( Picture 4 ). By adopting
this, usage of electricity is reduced to minimal. The window openings also provide natural views in be-
tween spaces ( Picture 5 ).
	
	 Another passive design feature that is adopted by the building is the green roofing system
( Picture 6 ). This feature helps to moderate the temperature of a building by reducing solar gain, and
generally improving air quality of the surrounding.
	 Nanyang Technological University uses the extensive green roofing system due to the depth of
growing medium used, which is up to six inches or less ( Picture 7 ). Other characteristics that define
this green roof are its lower plant diversity and plant weight. By using the extensive green roof,
maintenance and cost of the building is reduced.
	 Green roofmainly helps in reducing the urban heat island effect, especially during the daytime. It
insulates the building by having moisture retention materials installed beneath the soil. The thickness of
soil used directly affects the indoor temperature of the building, as increase in soil thickness helps
reduce the temperature within the building. This is effective and can clearly be seen on the upper floors
of the building ( Picture 8 ). The roof provides savings benefit on heating and cooling systems.
	 Besides that the grass used on the roofs collects rainwater during heavy downpour for
landscaping irrigation ( Picture 9 ). This feature also contributes in the coolness of the roof area, as it
allows the grass to be consistently damp and gives off a cooling effect. A green roof not only provides a
beautiful landscape but it also enhances air quality by trapping air pollutants and re-oxygenating the air.

Project: Location: Case Study: Identifying innovative passive design strategies Nanyang Technological University, School of Art Media and Design, Singapore Architect: Designed by CPG Consultants “As a group, we constantly push the frontier of infrastructural and architectural design trends to meet the needs of modern facilities and their usage. Thus, one of our most distinctive design niches is environmentalism. The team is concerned and mindful of the impact modern infrastructure can have on the environment and we are hence, constantly producing solutions that enable us to co-exist with nature in harmony.“ CPG Consultants, Green Approach Introduction Nanyang Technological University is one of the largest public universities in Singapore which boasts a 200 hectare campus. Each school has their own building on the campus ground. One of the new building inside the campus ground was built for its School of Art, Design and Media. The building is a green building designed and built by CPG consultants which caters to the environment by means of passive design relative to the tropical climate and is recognised by Singapore’s Green Mark System (Davis, 2012). Climate Climatically both Singapore and Malaysia are a hot and humid country; Singapore, a city-state, lies 1° north of the equator. This essentially contributes to it having a tropical rain forest climate along with its maritime exposure. Due to the country being Nanyang Technological University’s School of Art, Design and Media achieved the Green Mark Platinum Award (refer to Image 3) from the Building and Construction Authority for adopting best practices in environmental sustainability (Green Mark). Green Certification surrounded by water, its temperature has minimal fluctuations, negating the four seasons (Bruno, 2011). 1

  • 6. This unique building is situated in Singapore, specifically in the 200-hectare Yun- nan campus, adjacent to the Jurong West district of Singapore. It is situated at a crossroad between Nanyang Avenue and Lien Ying Chow Drive and is flanked by the Simtech Valley Block. The building is used mostly during the day when the students and staffs occupy it and is left empty during the night. It is spaced apart from nearby buildings as it houses the School of Art, Design and Media. SITE LOCATIONTop Image 4: Site Plan of Nanyang Technological University, School of Art, Design & Media 3

  • 9. Dense voysiamatrella grass turf The grass turf helps to absorb Singapore’s intense sun which decreases the temperature of the air surrounding the university. Moreover, thus eco-friendly attribute enhances the outdoor gathering spaces of the university. Top Image 7:Photograph of the dense voysiamatrella grass turf 5
  • 10. Exposed Facade The facade of the building is an expansive curtain wall facades of high-performance, double-glazed glass. It is longitudinally oriented east-west and more north and south exposures. The glass curtain walls maximizes interior daylight while minimizing heat penetration. Double-glazed windows are windows with two sheets of glass separated by an air tight gap. This creates an insulation barrier and helps prevent heat loss in winter and heat gain in summer. The combination of high insulation frame, twin compression seals and double glazed units gives a level of thermal efficiency that is unsurpassed. Double glazing is designed to minimize heat transfer.

  • 13. Curved Green Roof The curved green roof that casts in heavily ribbed, reinforced concrete which also forms the double curve layout The green roof reduces solar gain and slows run off during Singapore’s frequent downpour. The turfs are irrigated using rainwater collected in the storage tank. Moisture retention materials are installed beneath the soil helps keep the grass consistently damp that creates a surrounding temperature that is not too hot. This helps in creating a thermal environment that is comfortable for the occupants of the university. Top Image 11: Photo- graph of the curved green roof in the site 9

  • 18. Singapore’s climate is character- ised by uniform temperature and pres- sure, high humidity and abundant rainfall because of its geographical location and maritime exposure. Relative humidity is in the range of 70% - 80%. Buildings constructed in high humidity locations need to have dehumidification capability to avoid moisture build up inside the building, causing discomfort and moulds. Humidity Singapore maintains its tem- perature throughout the year with little changes between its maximum and minimum temperature. The average temperature is between 23 degrees Celsius and 31 degrees Celsius. April is the warmest month, January is coolest month and November is the wettest month. In terms of building design, exposed heavy construction materials with low heat conductivity materials is highly favourable such as concrete which reduces heat gain into the build- ing and store cooling energy.

  • 22. Upon completion of our research, we have found out that the consultants took a lot of measures to design this building in accordance with the natural sun orientation as their idea were to build an open space university (2014). Referring to the site plan, this building is located in the housing area with a proper development from the Singapore’s government. As it is situated far from the main city, there is no natural shading from the surrounding building except for the location natural vegetation. Thus, the consultants built this building with a proper orientation by placing the facades facing north and south to minimize solar gain. After achieving the right orientation for build- ing, the facade is fixed with glass curtain walls. Benefits from Site Context During our site visit, we felt really comfortable when we were inside the building and also in the courtyard. According to D.K Ching, taking advantage of the land or ecology of the building is one way to enhance green building’s factor. Thus, the purpose of almond-shaped courtyard in the middle of the building is to provide natural lighting into the interior. Next, the consultant took advantage of the sun orientation by designing a green roof. According to Alwitra GMBH.co, the purpose of the green roof is to bring out the aesthetic value of the building from other conventional multi - storey buildings, in the campus and in the city (2013). Moreover, the green roof functions to cool the building environment by absorbing Singapore’s intense sun and slowing runoff during Singapore’s downpour (2014).

  • 23. Absorb Singapore's Intense Sun The Image 19 until Image 21 is a proof of the sun orientation on the Nanyang Technological University School of Art, Design and Media. The date and time was set through the analysis of Singapore’s season which are North-East Monsoon Season,Pre South-West Monsoon, South-West Monsoon Season and Pre North-East Monsoon. The consultant achieved their intention to make use of the building orientation, green roof and etc to overcome the Singapore’s intense sun. As the curtain glass wall is orientated to the north and south, there is no full exposure from the sun as it is only direct to the courtyard. Next, since the green roof is on top of the building, it is fully exposed to every direction of the sun to oppose the Sun heat.

  • 27. Top Image 26 The courtyard of Nanyang Technological University The northeast monsoon season, from December to the beginning of March, is when north-easterly winds prevail. Whereas, the southwest monsoon season from June through September, is when south-easterly or south-west- erly winds blow. (Figure 5) Due to the 2 monsoon seasons and the location of Nanyang Technology University which is relatively near to the sea, the amount and speed of wind flows are higher and faster compared to the other months and locations.(Image 27) For the building itself, the verdant turfed roof and the courtyard are the two spaces that would be well ventilated. ( Image 29 ). Sun Path Case Studies The sliding doors and opened windows are also allowed the air ventilation to flow throughout the building. Winds are incorporated onto the roof and also the courtyard to allow students to feel cooled. Moreover, the presence of wind helps to lower down the temperature outside while the majority of interiors such as the counter area, halls, classes, studios, admission centre, and so on are ventilated by using air conditioners. ( Image 29 ). However, the air conditioning are switched off after 11pm every day. It is to be eco-friendly.For Nanyang Technology University, the wind flows helped to improve the thermal comfort. 20

  • 31. When people are displeased with their thermal environment, not only is it a potential health hazard, it also impacts on their ability to function effectively, their happiness/satisfaction at work, the likelihood they will remain a customer and so on. BS EN ISO 7730 defines thermal comfort as ‘…that condition of mind which expresses satisfaction with the thermal environment. ie the condition when someone is not feeling either too hot or too cold. The human thermal environment is not straight forward and cannot be stated in degrees. Nor can it be reasonably be defined by adequate temperature ranges. It is a personal experience dependent on a countless number of criteria and can be different from one person to another within the same space. Thermal Comfort Analysis For example, a person walking up stairs in a cold environment whilst wearing a coat might feel too hot, whilst someone sat still in a shirt in the same environ- ment might feel too cold. The Health and Safety Executive propose that an environment can be said to attain ‘reasonable comfort’ when at least 80% of its dwellers are thermally at ease. This means that thermal comfort can be assessed simply by surveying inhabitants to find out whether they are unhappy with their thermal environment. At one degree above the equator, the climate in Singapore is typically tropical; hot and humid throughout the year. The temperature usually lingers around 30 degrees Celsius (86 degrees Fahrenheit) with 75 per cent humidity. Rainfall is slightly higher during the winter with a monthly average of 260 millimeters (10 inches) and summer months averaging 170 millimeters (six and a half inches). 23

  • 33. Enlivened by fountains, cascad- ing water and a “floating” performance platform, the reflecting pond of the building’s interior courtyard both creates ambience and cools a pleasant commu- nal area in the center. The main green feature of the building still remains the iconic curved green roof. A living or green roof is a roof that is substantially covered with vegetation. These have positive effects on buildings by reducing the stress on the roof sur- face and increasing their life, improving thermal comfort and reducing noise transmission inside the building, reducing the urban heat island effect, reducing storm water runoff, re-oxygenating the air and removing airborne toxins, recycling nutrients, and providing habitat for living organisms, all of this while creating peaceful environments. Therefore, green roofs do have an immediate effect on the thermal comfort of a building. Indoor temperature reduces in the buildings having green roofs with the increasing of the soil thickness.( Image 31 ) There is a significant influence of soil thicknesses in green roof for improving the indoor temperatures in the upper floors of buildings. However, soil thickness does not effect on the indoor temperature in the ground floor. The latter is affected by the curvilinear plan form of the building,creating an Top Image 30 Zone Floor Plan of Nanyang Technological University 25

The green roof is applied here on NTU, which has upper floors, exposed to the direct sun light throughout the day time as a passive element. Studies and experiments car- ried out by professionals have shown that the indoor thermal performance of a green roof is better than the traditional roofs. As a reason of aging of buildings, the absorptivity of traditional roof mate- rials increase. However, in a well main- tained green roof, this remains same as newly constructed green roof. The glass curtain wall is an- other feature which adds on to the thermal comfort of NTU. Windows are complex and fas- cinating elements in the material of a building. They allow light and fresh air and provide views that link interior spaces with the outdoors. Unfortunately, windows can be a maincause of un- desirable heat gain in hot weather and significant heat loss in cold weather. Windows can have a severe impact on the heating and cooling loads of a building. Up to 40% of a building’s heating energy can be lost and up to 87% of its heat gained through win- dows. (http://www.yourhome.gov.au/ passive-design/glazing) Improving windows’ thermal per- formance reduces energy costs, green- house gas emissions and improves Top Image 31 sections showing air flow, red is warm, blue is cool 26
  • 35. thermal comfort within. Careful selection of window glaz- ing greatly increases thermal comfort for people near to windows, especially large windows. The sense of comfort is not just determined by air temperature: the temperature of surrounding surfaces has a great impact. The goal should be to attain an inside glass surface temperature as close as possible to the preferred room air tem- perature. This means glass that is nei- ther cold in winter nor hot in summer. Although we lacked the time to do an in depth mathematical thermal behavior room-by-room analysis/mea- surement of the entire building, we did get to measure the dry bulb temperature from certain areas of the building, out- side to inside the double glazed glassed walls.

  • 38. One of the main features of Nanyang Technological University that can be noticed is the exterior glass curtain walling. It is utilizing passive solar design to help maximize natural lighting by using proper orientation of the building and providing appropriate shading to reduce overheating. The building is specifically orientated facing the north and south ( Picture 1 ). This is to minimize the solar gain and heat load in the morning. The glass exterior facade allows natural views and sunlight into the building, allowing visual exchange between indoor and outdoor spaces. This give an amazing experience while being in the building and enjoying the surrounding at the same time. The glasses are double-glazed to reduce heat penetration into the building, while allowing maximum interior daylight to pass through ( Picture 2 ). It helps to reduce the temperature transfer between exterior and interior spaces. Glass openings are also placed throughout the interior walls to provide natural sunlight diffusing through each space. This allows continuity of lighting throughout the building ( Picture 3 ). Strategic window placements for rooms and toilets that are placed underground enhancenatural lighting into the building. This allows sunlight to illuminate the spaces inside ( Picture 4 ). By adopting this, usage of electricity is reduced to minimal. The window openings also provide natural views in be- tween spaces ( Picture 5 ). Another passive design feature that is adopted by the building is the green roofing system ( Picture 6 ). This feature helps to moderate the temperature of a building by reducing solar gain, and generally improving air quality of the surrounding. Nanyang Technological University uses the extensive green roofing system due to the depth of growing medium used, which is up to six inches or less ( Picture 7 ). Other characteristics that define this green roof are its lower plant diversity and plant weight. By using the extensive green roof, maintenance and cost of the building is reduced. Green roofmainly helps in reducing the urban heat island effect, especially during the daytime. It insulates the building by having moisture retention materials installed beneath the soil. The thickness of soil used directly affects the indoor temperature of the building, as increase in soil thickness helps reduce the temperature within the building. This is effective and can clearly be seen on the upper floors of the building ( Picture 8 ). The roof provides savings benefit on heating and cooling systems. Besides that the grass used on the roofs collects rainwater during heavy downpour for landscaping irrigation ( Picture 9 ). This feature also contributes in the coolness of the roof area, as it allows the grass to be consistently damp and gives off a cooling effect. A green roof not only provides a beautiful landscape but it also enhances air quality by trapping air pollutants and re-oxygenating the air. GREEN ROOFING SYSTEM Passive Solar Design 29
