Revised Summary and Reader Response Based on Professor Blackstone's feedback

 In the webpage, “District heating and cooling systems'', ENGIE (2013) has discussed the benefits and advantages of adopting a cooling network system. A cooling network is a centralized system that supplies chilled water to an air conditioning system. ENGIE has been established as the world’s largest independent provider of urban cooling networks by Tabreed, a leader in the Gulf state urban climate control systems market. The webpage has mentioned that ENGIE has customized its services based on the customers’ needs. ENGIE’s approach for its cooling network in comparison to a conventional air conditioning system has achieved greater energy efficiency, lesser water and electricity consumption, and has emitted less carbon dioxide. The advantages of implementing a cooling network can be seen from ENGIE’s operation in Paris, which is one of the largest cooling networks in the world. Its energy efficiency has improved by 50% and its carbon dioxide emission has been reduced by 50%.

Since the webpage has demonstrated that the implementation of a district cooling network system has a sustainable impact on the environment, Singapore should require more commitment to implementing more district cooling networks projects as such networks will be a contributing factor to mitigate the current Urban Heat Island (UHI) effect and greenhouse gas emissions, which are contributing determinants to Singapore’s climate change problems. Existing projects are not sufficient to tackle the issue.

According to SP Group (2021), one project in Singapore that has implemented the district cooling network has been operating at Marina Bay since 2006. This project is the world’s largest underground district cooling network. It is operated by Singapore Power (SP) Group. The system serves more than 20 developments. The notable customers are developments such as the iconic Marina Bay Sands, Gardens by the Bay, and the Marina Bay Financial Centre (SP Group, 2021). They are expected to save more than 40% energy savings (Othman, 2016). Consequently, immense energy has been saved, and carbon dioxide emission has been reduced, which is a great way to tackle Singapore’s climate change problems.

Two upcoming projects in Singapore will be adopting the district cooling network system. Firstly, ENGIE has been awarded by Jurong Town Corporation and Singapore Institute of Technology to design 30,000 refrigeration tons of District Cooling System infrastructure in Punggol Digital District (PDC) in Singapore (ENGIE, 2019). PDC is the first district in Singapore to take on an integrated masterplan approach that brings together a business park, a university, and community facilities. This project will enhance energy efficiency and sustainability. Secondly, a future HDB town called Tengah will be Singapore’s first sustainable town that incorporates the centralised cooling system (CCS). A lower carbon footprint will be achieved with this system compared to other HDB estates in Singapore which will be similar to removing 12.6 million kg of carbon dioxide from the air. Therefore, with a lower carbon footprint, residents in Tengah will be enjoying 30% energy savings (Housing & Development Board, 2021). This Built to Order (BTO) project will be an enabler for future housing development projects to undergo the same methodology to alleviate Singapore’s climate change issues.

Despite having the largest cooling network globally and the district cooling network having a sustainable impact on the environment, future residents in Tengah are not concordant with the cooling system to be installed in their property. According to Ng (2020), approximately 1,000 households from 8,000 flats that were launched in the BTO exercise have opted for the cooling system. The ratio of the opted households to the households that do not opt for the cooling system shows that Singaporeans in general do not understand the importance and advantages of adopting the cooling network system.

Thus far, the implementation of a district cooling network in Singapore has only been carried out in new developments. A district cooling network has yet to be implemented in completed developments in Singapore. However, according to Temasek (2021), this may change because of a feasibility study done by Temasek and SP Group to transform Tampines into a sustainable town by 2025. The study involves 14 buildings in Tampines to utilise a distributed district cooling (DDC) network. Data collected has shown that DDC in Tampines could likely achieve a 17% reduction in energy consumption, 18% fall in carbon emissions from both energy savings and refrigerant reduction. The owners of seven of those buildings, including CapitaLand and Frasers Property, signed letters of intent with SP expressing their interest in subscribing to the district cooling network.

Successful implementation of the DDC network in Tampines would be a pathway for many developments that are already built upon to adopt the district cooling network. Therefore, in an effort to contribute to sustainability in Singapore, the government has to start implementing more district cooling networks on older developments. The current and upcoming projects show that Singapore has shown commitment to installing more cooling networks. The implementation of the district cooling networks will contribute to mitigating Singapore’s current UHI effect issue and greenhouse gas emissions.

Formal Letter (Descriptive Reflection)

Dear Professor Blackstone, My name is Mohamad Zulfadli, and I am a student from T5 in your Effective Communication module. I am currently pursuing a bachelor’s degree in Sustainable Infrastructure Engineering (Building Services). The purpose of this letter is to provide a descriptive reflection of myself.   I have graduated with a Diploma in Mechatronics from Temasek Polytechnic. After that achievement, I was enlisted into the Singapore Armed Forces to serve my National Service.  After serving the nation, I have attained a Specialist Diploma in Biomedical and Pharmaceutical Engineering from Nanyang Polytechnic in parallel with working as an Assistant Quality Engineer. After my stint as an Assistant Quality Engineer, I have worked as an Assistant Technical Support Engineer. My passion for learning engineering comes from my uncle as he has constantly shared with me his exciting projects while working as a Civil Engineer. In addition, a show called “Mythbusters” has further p...

THE IMPORTANCE OF COMMUNICATION SKILLS FOR ENGINEERS

"Developing excellent communication skills is absolutely essential to effective leadership. The leader must be able to share knowledge and ideas to transmit a sense of urgency and enthusiasm to others. If a leader can't get a message across clearly and motivate others to act on it, then having a message doesn't even matter." Gilbert Amelio, former President and CEO of National Semiconductor Corp Effective leadership requires a leader that has excellent communication skills and can connect with the team members. It is essential to possess excellent communication skills as it inspires positivity towards the team members. A leader can inspire positive change and align with the team by imparting knowledge and ideas. Poor communication skills may lead to misinterpreted information and lowered employee productivity and morale.

Critical Reflection

  Module Learning The initial goals that I have set myself at the beginning of the module are to improve my public speaking skills and my critical thinking skills. The first step that has improved my public speaking skills is the opportunity given to speak in every session of the module. Professor Blackstone will be calling each student once to read a portion of the instructional units. Hence, this has allowed me to be more comfortable and confident when facing an audience. In addition, impromptu presentation in class has further solidified my improvement in public speaking skills. The module has introduced me to many resources such as “Garr Reynolds’ Presentation Tips” for example. There was one impromptu exercise where the students must read up on different sections of “Garr Reynolds’ Presentation Tips” and had to present the key takeaways to a breakout room. This exercise has allowed me to understand the importance of presenting key points. This exercise can be applied at work...
