SUMMARY DRAFT 2: IMPROVING INDOOR AIR QUALITY


According to Guidelines for Good Indoor Air Quality in Office Premises by Ministry of the Environment (1996), it presents on ways to improve the indoor air quality of a building through the design and construction of the air conditioning and mechanical ventilation system (ACMV). A certified personnel must inspect the ACMV system at all stages of construction to prevent the spread of contaminants and bacteria through circulated air. In order to achieve good air circulation through both natural and mechanical means, outdoor air must be filtered for foreign debris, fixed amount of air changes per hour are necessary. It is ideal to design and construct the air intakes to be located where air are the cleanest, supply and return ducts to be made easy to reach for maintenance and cleaning. Building components that does not belong to the ACMV system must not be in air-handling rooms.

UNIT 2 TASK 4: WRITING A FORMAL EMAIL

Dear Prof Brad, I am posting this blog post as an introduction to you. My name is Wu Lok Tin, currently a student for Sustainable Infrastructure Engineering (Building Services) programme. I graduated from Temasek Polytechnic with a diploma in Integrated Facilities Management, which was where it sparked my interest in continuing my studies in this field of industry. Initially I had difficulties in speaking to strangers, fearing of not knowing how to keep the conversation going. However after spending 4 months of my student internship programme in Walt Disney World as a cast member, where I was forced to speak to strangers every day as the job requires, speaking and expressing myself to strangers did not seem difficult after all. I have learnt that if I want to approach others, I must first be approachable. On the other hand, because I was born and raised in a non-English speaking family, where communicating in complete correct English sentences were almost non-existent. Somet...

CRITICAL REFLECTION

Looking back for the past trimester, I had a deeper understanding of the process of crafting a complete proposal. From identifying the problem to finding ways to work towards the goal. Of course, the module was not just on educating me on how to write a report, but also crafting a good thesis statement that could attract the reader’s attention and also paraphrasing / citing from credible sources the proper way to avoid plagiarism. I have set goals of wanting to speak / write better and exercise more patience before making a comment. In the short period of thirteen weeks, I would not dare to admit that I have improved on my speech nor my writing, but at least now I have the knowledge to craft a complete proposal. As for exercising more patience in listening to others before making a comment, I would say I have grew better in this. This might be due to the overwhelming workload that was given to us, which we need to accomplish many things in a short period of time, that lead me to b...

PRESENTATION SHOWCASE

I was impressed by the quality presentations made by my course mates, which made me question my own presentation that I did during the final presentation. I particularly liked the last presentation. Not because their idea was brilliant, but it was the attitude that they portrayed which was so positive and such assurance that what they are presenting will be implemented. It is important to believe in what I am presenting, so to be able to present and propose my idea to others. They had such high energy level in the presentation, which made the audience engaged into listening to them. I would love to reach such level of confidence in my presentations. Other than the presentation, I have learnt from the judges that the proposed solutions need to be practical and not just a depthless speech. Behind every solution proposed, the disadvantages of the solution need to be highlighted to the audience too. Because we never know when would something fail, and there must be another solutio...
