Career Prospects

With growing worldwide concern about the environment today, the focus has been on “green” buildings that are designed to reduce the impact of the built environment on human health and our natural surroundings on a sustained basis.

The Singapore government is targeting for 80% of buildings in Singapore to obtain the Building and Construction Authority’s (BCA) “Green Mark” certification by the year 2030. This is being driven by a new S$600 million government fund to “green” all existing public and private buildings, as well as the newly established Singapore Green Building Council to promote sustainable construction.

This course will equip you with the knowledge of green building technologies and practices, including indoor air quality, the efficient use of energy & natural resources, and energy auditing.

Green buildings currently make up only 16% of buildings in Singapore but come 2030, that figure is targeted to reach 80% of all buildings. This alone gives an indication of the enormous amount of retrofitting that will need to be done to buildings in our country, creating abundant job opportunities and a sustainable demand for green building professionals.

You can look forward to rewarding careers in the energy conservation, sustainable design or building design industries, and find exciting job opportunities as:

  • Energy Auditor

Student Achievements

Competition Awards

Building Information Modelling (BIM) Competition 2017
Tasked with conceptualising a design for the redevelopment of two blocks of building in the BCA Academy, a team of students from the Diploma in Green Building & Sustainability (GBS) designed a wedge-shaped module behind a complex structure using computational analysis, design and optimisation.  Their design won them the Bronze award in the annual BIM competition, organised by the BCA in Aug 2017.

Building Energy Efficiency Solutions Student’s Competition 2015
GBS students won the top Platinum award in the competition, with their proposals to improve the energy efficiency of the Marina Bay Financial Centre Tower 1.  Their proposals included a Heat Recovery System to extract heat from warm air in the car park to produce hot water for a restaurant in the building, a Car Park Ventilation and Lighting System with transparent “Skylight” solar glass on the Plaza to allow daylight to filter through and promote natural ventilation, and a Smart BMS (Building Management System) which uses “data analytics” to identify sensors in the building which have “drifted” and need to be recalibrated, thereby saving on manpower needed to manually test every sensor.

Energy Innovation Challenge 2015
A group of 3 GBS students won a Merit award in the competition with a device they invented, called “Sound Power”, which can harvest electricity from sound, thereby reducing the reliance on conventional energy sources.  The device can be placed almost anywhere, particularly at strategic locations, to directly power equipment which have low power demand.  The prototype was designed to tap and convert sounds of a specific frequency to produce 1.5V that can power up to 5 LEDs lamps.

Geospatial Challenge 2015
Three GBS students won the top Distinction award at the Singapore Geospatial Challenge 2015 competition, held on 29 July 2015.  Their project involved doing an analysis of Ang Mo Kio-Bishan Park to determine the best locations for installing park tables and benches as well as exercise facilities (or for having your picnics!), that would provide the best thermal comfort and most healthy air quality.  The team assembled their own air quality sensor and used it to collect data on the temperature and carbon monoxide levels at different times of the day. Using ARC-GIS software, they then analysed the data to pin point the best positions on the ARC-GIS map. 

Young Mayor Competition 2015
A team of 5 GBS students applied what they have learnt in their GBS course and proposed town planning solutions for Manila city.  Judged to be the best among participating tertiary institutions, their proposals won them the Gold award in the competition held on 11 & 12 April 2015.  In addition, the city model which they built so impressed the judges that it was given a special mention and “Best Prototype” award.  Their winning built up model of Manila city was also exhibited at the Choa Chu Kang and Serangoon public libraries in April & May 2015.


Energy Audit of a Retail Mall

The aim of this project was to develop baseline information on the existing chilled water plant of a building, so as to understand its current efficiency.  The data could then be used by the M&E Engineer to finalise the design for a proposed retrofit to the plant, so as to make it work more efficiently.  Having sufficient buffer space around the cooling tower, for instance, promotes better air flow which increases the efficiency of the plant.

Heat Penetration Analysis

This project aimed to compare and analyse the heat penetration through various types of glass panels.  The glazing that allows the minimum heat penetration will be considered the most energy efficient as it helps to reduce the cooling load and hence save energy.  The study involves 2 glass panels, with each panel comprising a single-glazed glass and a double-glazed glass.  The first panel uses clear glass whereas the second panel uses tinted glass.  It was found that clear glass panels were more effective than tinted glass in preventing heat penetration, while double-glazed glass performed better than single-glazed ones.

Solar Chimney Design & Performance

This project, done in collaboration with the Institute of High Performance Computing (IHPC) of A*STAR, aimed to develop solar chimney design guidelines for low-rise buildings in tropical regions.  The studies investigated the use of solar chimneys for indoor ventilation improvement.  PHOENICS, an industry-accepted Computational Fluid Dynamics (CFD) software package, was used to simulate the indoor airflow, temperature and pressure distribution. 


Investigation of Irrigation Efficiency of Cassette Vertical Greenery System

This project aimed to investigate the existing irrigation input method, so as to develop a more efficient irrigation input method that would use less water.  The existing irrigation input method was evaluated to ascertain the excessive water consumption was due to water run-off or an incorrect input method for a particular vertical greenery cassette system.  Tests were done for different planting substrates such as coco peat, green fabric, and grey fabric, by looking at each substrate’s weight when it is dry and when wet.  It was found that coco peat had the highest water retention ability


Building Energy Analysis Using Simulation Software

This project involves building energy simulation by using two different software suites, viz. IES and e-Quest.  The 3D models of two buildings, Blk A and Blk B, within the premises of Singapore Aero Engine Services Ltd (SAESL), were developed and the energy consumption of each building was in turn simulated via each suite of software.  The results were then compared against the measured energy consumption obtained via an energy audit.  The more accurate software was then used to predict the energy consumption for a lighting retrofit proposed for both buildings, and hence the energy savings.


The Diploma in Green Building & Sustainability (GBS) is supported by the latest technology and facilities to support teaching and student learning.  Geared towards the industry, these facilities and equipment ensure that our GBS students are industry-ready upon graduation from TP.

Green Building

Our very own “green building” in Temasek Polytechnic provides a realistic outside-the-classroom learning experience, where students can get to see, feel, explore and use green facilities such as a roof-top garden with complete electricity-generating solar panel system.

The award-winning building is also designed to be eco-friendly, with green landscaping on the walls to cool the building as well as special architectural features such as roof windows and strategically placed ventilation panels.

Computer Lab for Building Modelling

Computer labs are installed with the latest industry software such as Ecotect Analysis, AutoCAD, Revit, IES and PHOENICS, to equip students with important software knowledge in designing, constructing and simulating building models to optimise energy usage and occupants’ comfort – which are all important skills required in the designing of a green building.

Mechanical & Electrical Labs

Our Mechanical and Electrical labs are equipped with various facilities to familiarise students with the building services and equipment that function as the “internal organs” of buildings.  Some of these facilities include:

a) Air Handling Unit

The Air Handling Unit (AHU) is the driver behind cool and comfortable air in builidings.  It is used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system, and usually comprising a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.  In a building, it is connected to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU.

b) Chiller

The heart of a building’s air-conditioning system, chillers are responsible for cooling the air before it is blown into a builiding.  The cooling is done by running hot air through the massive pipes that you see here, which is then cooled by cold water.  Students get to learn about this important component of a buildilng, without which the air-con systems of buildings cannot function.

c) Electrical Lab

Each desk in this lab comes equipped with a mock up electrical board which students use to learn about electrical circuits and connections, which actually run like arteries through a building (just that you don’t see them because they are hidden either underground, behind walls, or above celiing boards!)  Learning how to make these correct connections is critical, as a wrong connection could cause a short circuit or fire.

d) Mechanical lab
This Mechanical lab is packed with equipment to allow students to study the principle of thermodynamics, which is the connection between heat and temperature and how they affect the output, as well as fluid mechanics which is the study of the effect of forces on the motion of fluids in buildings and other facilities.

Diploma Student Club

The student club of the Diploma in Green Building & Sustainability (GBS), called ASHRAE, is a student chapter of the American Society of Heating, Air-Conditioning & Refrigerating Engineers (ASHRAE), a global society advancing human well-being through sustainable technology for the built environment.   

The diploma’s ASHRAE club regularly organises activities for GBS students to create bonding as well as to help raise awareness and understanding of sustainability issues.  Some of the activities organised by the club include:

Study Trips

1) Visit to NEWater Plant
GBS students paid a visit to the NEWater Visitor Centre, where they learnt about NEWater, a high-grade reclaimed water which is produced from waste water that is treated and purified using advanced membrane technologies and ultra-violet disinfection, making it ultra-clean and safe to drink.  The GBS students learnt about the three important processes in the making of NEWater, and of course, literally had a taste of NEWater. 

2) Study Trip to Korea
GBS students went on a study trip to South Korea (28 Oct – 3 Nov 2014), where they visited various facilities such as  the Everland Theme Park, the Posco Green Building and Samsung Museum, among others, to learn about various building technologies, the operation and management of these facilities, and the green and sustainable practices adopted in South Korea.

At Everland Theme Park

3) UWC (SEA) Campus
A stone’s throw away from the TP campus sits the United World College of South-East Asia (UWCSEA’s) east campus.   A study trip to this Green Mark Platinum award-winning facility was organised for about 30 GBS students and 10 staff in July 2013.  The campus’ green features include a deliberate north-south architectural orientation to minimise exposure to solar radiation, light shelves in classrooms to utilise natural daylight, the use of 100% fresh air for cooling and ventilating classrooms, and an energy-efficient chiller plant which also serves as a showcase-cum-learning platform for one of the Building & Construction Authority’s certification courses.

4) South Beach Conservation Site
A study trip was organised for final year GBS students to South Beach, a planned commercial and residential complex located along Beach Road, due for completion in 2016.  The project includes the restoration of four conservation buildings, including the former Non-commissioned Officers' (NCO) Club and part of the former Beach Road army camp.  The trip, which was part of their “Sustainable Design” subject curriculum, allowed the students to observe how key architectural features, such as old window frames and embellishments are carefully retained and restored, and how the building’s façade is preserved amid the rapid urbanisation of the surroundings.  It is one of the ways that our School makes lessons come alive for our students. 

5) District Cooling System Plant
A study trip was also organised to the District Cooling System plant at Marina Bay Sands in July 2015, where the 30 GBS student participants found out about the large scale chilled water distribution system.  This technology allows a building’s chiller plant (which produces chilled water for air conditioning) to operate largely during the off-peak period (when electricity tariffs are lower) to produce ice which is then stored.  The stored ice is then melted during the peak period (when electricity costs more) to chill the water that is pumped through the air-conditioning units, thereby resulting in immense cost savings.

Student Events

1) Artitude 
A musical talent show case organised by the GBS student club, “Artitude 2014” was held at the campus’ Auditorium 3 on 8 May 2014.  Performances by 15 budding contestants, as well as a special guest appearance by a dance group got about 250 GBS students and lecturers all hyped up, some standing up to dance, some bouncing in their seats.  It was a fun-filled event reflecting the work hard-play hard life of GBS students.

2) Sub Comm Training camp
Sub Comm Training camps are held each year to groom the next cohort of ASHARE main committee members.  These main comm members are the student leaders who organise and spearhead the activities for all members; they are the livewire of the club.

Alumni Success Stories

1) Sabrina Au (2014)

Sabrina graduated with Diploma in Green Building & Sustainability (GBS) in 2014. She says: “My GBS diploma equipped me with the knowledge and necessary software skills needed in the industry – such as Revit and AutoCAD. I was also given an opportunity to experience the real working world during my internship in my final year. The lecturers were also helpful and nice, making my poly life a more enjoyable one,” she explains.  Sabrina is pursuing a degree in Mechanical Engineering at NTU.

2) Priscilla Bai Xin'er (2014)

Priscilla graduated with a GBS diploma in 2014. This is what she has to say about the GBS course: “My GBS course helped me to realise that my passion is in doing hands-on work such as energy modeling. The Building Information Modelling subject in my diploma course was really useful as it helps me a lot at university,” she says. Priscilla is pursuing a degree in Construction Management at the University of Newcastle.

3) Lee Yu Xuan (2014)

After getting her GBS diploma in 2014, Yu Xuan went on to pursue a Bachelor of Engineering (with Honours) in Sustainable Infrastructure Engineering (Land), and a Master of Engineering Technology at the Singapore Institute of Technology. She is convinced that her GBS diploma has given her a strong head-start in her university modules.  She says: “I feel that the modules taught are well structured with sufficient lab lessons, tutorial lessons and lectures. It has not only provided me with a good theory foundation but also given me a hands-on learning experience. The interpersonal and communication skills which I have gained have also been very helpful for my “integrated work-study programme” module at university.”

4) Giselle Lim (2014)

Giselle chose the GBS diploma in TP because, she says, of her “strong interest in green buildings”. Today, she has no regrets. "I'm happy I made the right decision. The knowledge and skills imparted from my lecturers have been invaluable and highly applicable to the demands of the industry. It has also provided me with strong foundation for my university studies. Giselle is pursuing a degree in Mechanical Engineering at NUS.

5) Jeannie Teo (2014)

Jeannie, who graduated with a GBS diploma in 2014, is most grateful that her diploma has earned her a place to study design in the Singapore University of Technology and Design (SUTD). She says: “The things which I learnt in GBS are also closely related to design, for example, the module “Sustainable Design”. This gave me a strong design foundation, thus making me eligible for a place in SUTD.”

6) Joshua Fong (2006)

Joshua graduated from the former Diploma in Intelligent Building Technology (now renamed as Green Building & Sustainability) in 2006. He went on to pursue a Degree from the Northumbria University, UK, where he graduated with a First Class Honours in Building Services Engineering, and then obtained his Master of Engineering, before attaining his fully-funded Ph.D under the supervision of one of the industry's leading experts, Professor Chris Underwood. His Ph.D research involved developing computer codes for HVAC components and at the same time reducing computational cost for the building modelling software, “DesignBuilder”. "Choosing to pursue a diploma from Temasek Polytechnic rather than taking the JC route was a simple and straightforward decision for me. I wanted something very hands-on and practical, and I got it,” he recalls. Given his interest in architecture, modern technology and physics, the IBT diploma (aka Diploma in Green Building & Sustainability) was the perfect choice. “My diploma training came in really handy, especially when I did my Ph.D programme which involved Energy Engineering and Computer Science.

7) Joey Ng (1998)

Joey Ng was among the first batch of diploma graduates from the former Diploma in Intelligent Building Technology (IBT, now renamed as the Diploma in Green Building & Sustainability), who graduated in 1998. After working for a year, she went on to pursue a degree from the University of Nottingham, UK, where she graduated with First Class Honours in Building Environment Engineering. The technical knowledge as well as analytical skills which she gained from her IBT diploma gave her an edge at university.  Joey is currently Deputy Head (Sustainable Design Technologies) at Surbana Technologies Pte Ltd, where she manages a team of professionals in the field of sustainable built environment, doing master-planning for projects in the Middle East & various countries in South East Asia. She is also a LEED Accredited Professional (US) and a GBI Facilitator (Malaysia). When asked for the secret of her success, this highly successful young lady says, “Be pragmatic in the way you handle tough situations & be spontaneous to new opportunities.”
