Critical Reflection – The Role of Peer and Tutor Feedback

Upon entering university, time seems to be ticking very fast and learning styles are different. In a new environment, it will be good to have nice peers and lecturers to guide and offer positive feedback for improvement. In the module, Effective Communication, posting assignment and reflection on a blog is something new that I have never experience before.

Firstly, I was not very positive about posting reflections on the web as it is a public space where everyone can see. However, when the whole class started posting online, my views changed. I became more open to it and felt that it was a good way to let your classmates know about your reflections.

Posting on blog and receiving feedback from peers is a good way to know how other people sees your work. It is also a good motivation to improve your work. It does not matter whether the feedback is good or bad as it is still a constructive feedback that will help to improve language skills.

Receiving feedback from the tutor will help you to see where went wrong and how to counter it. Tutor may also improve on the peer’s feedback if there are mistakes in it. With this, both students can learn at the same time, reducing the need for the tutor to repeat the same thing again.

After receiving feedback from my peers and tutor, I felt that my English language was better as compared to when I first entered university. I think it was the greatest takeaway from this course and I hope to improve my English language.

Assignment #2 Summary_Reader Response – Draft 4 (Final)

The article “The Concrete Advantage”, taken from the Green Rooftop webpage, provides readers with a deeper understanding of concrete green roofs. According to the article, concrete green roofs which incorporate “Permanent built in water-proofing”. This will lower construction costs and will not be damaged over time. The process of design, construction and maintenance will be shortened through the removal of membranes. The article states that with lesser exposure risk for owners and designers, concrete green roofs are more economical, which increase return on investment and project value. It is also more cost-effective for owners as there is no need for replacement of membranes, thus lowering life-cycle cost. The article also mentions that the usage of “hydrophobic technology” removes dangerous components, making fewer contact risks for anyone who owns the green roof. When there is crack on the green roof, a simple inoculation from the bottom side will mend it without disrupting growing mediums or plants. Leaks can also be detected easily with the waterproof concrete system as compared to a typical membrane system. From all the points listed above, one can understand that projects with a concrete green roof will have simpler design and lower life-cycle costs than typical green roof.

The first reason to support the above statement is by comparing typical green roof and concrete green roof. Concrete green roof does not require filter layer, drain layer and the waterproofing methods as all are permanently built-in. According to Wark and Wark (2003), a typical green roof consists of vegetation, growing medium, filter layer, drain layer, protective layer and waterproofing system. Filter layer is in between the growing medium and drain layer. It serves as a root barrier allowing water to flow through while retaining the growing medium. Similar to filter layer, the drain layer is in between the planting medium and roof membrane allowing water to flow from the green roof to the building’s drainage system. The article “Waterproofing green roofs”, taken from Growing Green Guide webpage, states that a strong waterproofing layer on the roof is essential to prevent water from slipping into the building. There are two types of waterproofing methods: liquid applied treatment and performed sheets. These waterproofing membranes must be protected from physical and chemical damage. Furthermore, these membranes are prone to wear and tear and will get brittle over time losing the ability to block off water due to environmental exposure.

The second supporting reason that concrete green roof is simpler and cheaper than typical green roof can be seen when designers and architects do not have to design and detail any waterproofing membrane and contractors do not have to wait for the concrete to dry before applying the membrane, these shortens project time and increases efficiency of team working on site. Leaks can be detected easily with the waterproof concrete system as it can only come from a crack or an improperly sealed penetration. However, in a typical waterproofing membrane system, they are difficult to trace and costly to repair. They can also cause damage to plants and growing mediums.

As demonstrated by the information in the above paragraphs, projects with concrete green roofs will provide owners, and project team with benefits in the long run. It is because of the simpler design as well as the lower life-cycle cost as compared to when using typical green roof.

Analytical Reflection – Oral Presentation

My group and I presented our project proposal; Implementing sensors in the new SIT campus at Punggol on 10th Nov 16. The presentation went on smoothly without hiccups. However, before the start of our presentation, it was intense and nerve wrecking. I was afraid that my mind will go blank and I will stutter during the presentation. Although, our group had some rehearsals to familiarise ourselves with the presentation flow and get ready.

I took out my courage and start the presentation confidently. However, there are some stumbling during the presentation. Luckily, I managed to get over it and continue. I tried not to speak too fast and make sure that the audiences understand the points that I was trying to get across.

I heaved a sigh of relief after the presentation. Upon reflection, I realized that I could have a more balanced eye contact with the audiences. This comes to the point that I memorized some of the materials that I was going to bring over. The flow was not smooth in my mind hence I tend to think about the next sentence that I am going to deliver.

I was being taught on how to prepare and deliver effective presentation and our group decided to adopt Garr Reynold’s presentation style together with Monroe’s motivated sequence. We kept the slides simple and with the usage of graphics, we limit the words in each slide. And to grab the audience’s attention, I asked a question at the beginning of the presentation. This is a new presentation style that I adopted and surprisingly I managed to pull it through.

Dear Mr. Chin,

Re: Proposal for the Implementation of Sensors in the new SIT campus at Punggol

Enclosed for your kind consideration is the proposal for the implementation of sensors in the new SIT campus at Punggol. This proposal has been developed as our group often come across lights and air conditioners switched on in classrooms and lecture theatres even when there are no users inside. Our team’s intention is to save costs and to reduce energy consumption for lights and air conditioners.

The report comprises of the current problems, solutions, benefits and a comprehensive summary of all the related research.

We would like to express our gratitude to you for taking the time to read through our
proposal. Your considerations of our proposal for making SIT more conducive and environmentally friendly is greatly appreciated.

Thank you

Yours Sincerely,
Cherlyn Tei

Dear Mr. Chin

Good day to you. My name is Cherlyn and I am a first-year SIE (Building Services) student. As I am currently in Brad Blackstone’s Effective Communication class, I have been assigned to a group of three including myself and was tasked to identify a problem in school and propose a solution. Our project focuses on sensor devices and as you oversee facilities development and hold a great deal of knowledge in this aspect, we would like to seek your advice regarding our project.

From what we know, lights and air-conditioners are used to illuminate and cool the surrounding for the occupants in the classroom, laboratory etc. As students usually stay back after school to complete their assignments, it is common for them to use the school facilities such as lights and air conditioners. The problem that we realized in school was that not many people have the tendency to switch the air conditioners and lights off before they leave the classrooms and lecture theaters, and this may result in unnecessary cost incurred and electricity will be wasted. To solve this problem, our group propose to come up with a solution which is to install sensors in classrooms and lecture theaters in the new SIT campus located at Punggol.

Our group would like to consult you and obtain some background information regarding the new SIT campus so that we can have a better understanding before we prepare our proposal. The main items that we require clarification for are as follows:

1. May I have more background information on the sensors installed in the current toilets?
2. Are there any plans to install sensors in the new classrooms or lecture theaters?
3. The type of motion sensors that you would recommend? E.g. Vacancy or Occupancy sensor?
4. May I know who will be in charge for the installation of sensor and designing in the new SIT campus in Punggol?
May I know when will be a suitable timing for us to consult you? Thank you and hope to hear from you soon.

Yours sincerely,
On behalf of Sensing Sensation

Executive Summary for Proposal Report

In this proposal, the concerns regarding lights and air conditioners not switched off in classrooms, lecture theaters and laboratories, resulting in higher energy usage are addressed. The group proposes to install sensors in places such as the classrooms, laboratories and lecture theaters in the new Singapore Institute of Technology (SIT) at Punggol. In line with SIT President, Dr. Tan Thiam Soon, he mentioned that the new SIT will be a “smart and green campus” that will be consistent with Punggol becoming the first eco-town in Singapore.

The proposal describes the various types of occupancy sensors along with their advantages and disadvantages. The purpose is to evaluate the effectiveness of each type of sensor to determine the most suitable one to be installed in the new SIT campus. Interviews were conducted to obtain more information on the development of the new SIT campus however, the team realized that there was no plan to install sensors in classrooms and lecture theaters. On the other hand, the management team in SIT is planning to conduct tests with regards to installing sensors in SIT classrooms at Nanyang Polytechnic.

With this proposal in place, the team hopes to reduce energy consumption, electrical costs incurred and at the same time bring the new SIT closer to being a smart and green campus.

Problem and Purpose Statement

Problem Statement
Lights and air-conditioners are usually switched off when students or staff members leave the SIT premises which includes classrooms, laboratories and lecture theatres. However, there are times when they forget to switch them off before leaving. Not Implementing an automatic sensor system will result in higher energy usage and unnecessary costs.

Purpose Statement
The purpose of this proposal is to propose the implementation of sensors in the new SIT campus at Punggol. These places includes classrooms, laboratories and lecture theatres. By implementing such sensor devices, SIT will be able to save significantly in cost as well as being energy efficient.
