Reader Response #3

According to the ENGIE’s webpage, “District heating and cooling systems” (2013) ENGIE aims to provide comfort to the public and conserve nature. ENGIE was awarded to be the “world’s largest independent provider of urban cooling networks”. Currently, they are managing 320 systems globally and can be seen in France, the USA and even in Malaysia. The webpage focuses on two systems, heating and cooling. The heating system focuses on warming up the building or city with the help of hot water and surcharge steam. It uses available resources for heat generation such as natural gas. However, the cooling network supplies cold water to the air conditioning system. In this system, distribution facilities and cold water production is needed for the services. According to the webpage, ENGIE's cooling systems help make a district greener in terms of energy efficiency and reducing operating costs.

One of the main outcomes of using cooling systems is that the district is able to use less energy. It is perfect for Singapore since it is heavily dependent on the air condition system to provide comfort to everyone due to its population and tropical weather. Both ENGIE and Singapore will team up to create their first district cooling system in Punggol. According to ENGIE’s webpage (2013), the cooling system “consumes 35% less electricity” and “greater than 50% energy efficiency” when being compared to the common air conditioning system. One of the advantages of energy efficiency is that the overall greenhouse gas emission is decreasing which help in conserving nature. Conserving nature helps in making the district a greener place.

The total energy has been reduced which lead to a lower operating cost. According to the webpage from ENGIE SEA (2019), Malaysia saved up more than $200,000 just by improving its cooling system and in the Philippines, the clients save up 13% of their savings. Another example of lowering operation costs is in Singapore, there is another cooling system that is similar to ENGIE’s. That cooling system is able to save $4.3 million annually. Lowering operation cost is one of the factors in creating a green city as the cooling system uses less energy, water and electricity. However, countries or cities that do not have district cooling systems and use the common air conditioning system suffer from a higher bill cost as it uses more of the resources.

However, the cost of installing the district cooling system is very expensive compared to installing chillers on each of the buildings’ roofs as stated by ICAX (n.d). “ENGIE announced an $80 million investment in Singapore to develop its Centre” for a 30 years contract according to ENGIE SEA (2019). At the same time installing the district cooling system might take a long time. The pipelines for the district cooling systems can be found underground.  Since there are a lot of pipes underground the worker need to pay close attention to the pipes to prevent them from damaging other properties.

 Although district cooling systems may cost a huge sum of money and take a longer time to be installed, a lot of countries and cities are still teaming up with ENGIE to have their own cooling system. District cooling systems may have their own disadvantages to it, the advantage of having it overweigh the disadvantage. There are a lot of benefits to the client and the country or city if they installed the cooling system. For example, reducing the amount of greenhouse gas released into the air and using less energy, electricity and water contributes too. Those advantages help in conserving nature, therefore, making the district a greener place.

Self Introduction: Formal Letter

Dear Professor Brad My name is Nur Farhanah. I am writing this letter to introduce myself to you. I graduated from Nanyang Polytechnic in 2021, where I studied Electrical Engineering with Eco-Design. Currently, I am a student at Singapore Institute of Technology pursuing a degree in Sustainable Infrastructure Engineering (Building Services). Truthfully, I did not expect myself to continue studying as I am still unsure of what I want to do for my future. There are a lot of different types of communication skills. I believe that friendliness is one of my strengths in communication. Where honesty and kindness can help foster trust and understanding. A friendly tone can also encourage people to communicate with us. However, lack of confidence is my weakness in communication. I get nervous when I need to stand in front of the class and present. That affects my communication as I tend to blank out and not present fluently during the presentation. After which, I regret not being able to pre...

The Importance of communication skills for engineers

  “ Communication skills are an essential component in the education of  engineering students to facilitate not just students’ education but also to prepare  them for their future careers.”    Marc Riemer, Faculty of Engineering, Monash University (2007) Throughout our school years, we will be partnering with different course mates, allowing us to communicate with them. Most importantly, sharing and understanding our ideas will also help us prepare for our careers in the future. Hence, communication skills are an essential component in the education of engineering students. Nur Farhanah

Critical Reflection

Module learning The two main goals I have set at the start of the Effective Communication module was to be able to improve on my writing skills and able to step out of my comfort zone. Before the start of this module, I was not strong with my language which affected my writing and I aim to improve it. Throughout this module, I was able to do and learn the different types of writing. I was able to know how to paraphrase and summarise without changing the meaning of the whole sentence which is important for our writing to avoid plagiarism.  Stepping out of my comfort zone where I was able to present and discuss more during the lesson. Throughout the module, I have learnt some valuable steps on how to present and do a pitch correctly. For example, capturing the audience's attention by asking questions and even eye contact. In my previous presentation in polytechnic, I was allowed to refer to my script and present it to the class and there was no proper feedback on my presentation. Whe...
