1.0 INTRODUCTION 1.1 PROJECT INTRODUCTION
Choosing a room as a site and mapping out and record down all main electrical fixtures namely, lighting and ventilation. Also, to draw out the electrical wiring to the switches. Observing what are the discomfort/problems with the existing lighting and ventilation and re-design the room within the scope of lighting and VAC equipment. Your justifications for change may be for enhanced comfort, eco-friendliness or aesthetics.
1.2 SITE INTRODUCTION The house itself is a two-floor terraced house with 3+1 bedrooms and 2+1 bathrooms, a living room, and family room. Using master bedroom as the site for the project, it is located on the second floor of the house in Jakarta, Indonesia.
2.0 ROOM LAYOUT
-
LED Bulb 13W Philips Essential E27 covered in dome light mounted AC Split Daikin 2 PK R32 STV50BXV
2.1 PROS -
The use of dome light mounted ease the brightness a bit The Air Condition is stable and cold for the size of the room
2.2 CONS -
The light above the bed is still too bright and too direct The dome light mounted looks cheap and unattractive
2.3 PROPOSAL -
Making concealed LED on top of the bed area to soften the lighting and use warm light rather than cool light or daylight with its own switch to control when to turn it on and off. Adding and replace the other dome light with downlight LED with smaller watt.
3.0 HVAC CALCULATION By steps 1. Room BTU = Area x 337 = 28.26 x 337 = 9523.62 BTU 2. Window facing south = Area x 870 = 0.96 x 870 = 835.2 BTU 3. BTU of users = 2 x 500 = 1000 BTU
4. Bulbs = 3 x 13 x 4.25 = 165.75 BTU 5. AC = 1063 x 3.5 = 3720.5 BTU TV = 50 x 3.5 = 175 BTU Phone Charger = 5 x 2 x 3.5 = 35 BTU Total = 3930.5 BTU
6. Total heat load = 9523.62 + 835.2 + 1000 + 165.75 + 3930.5 = 15455.07 BTU Amount of cooling required = 15455.07 x 2 = 30910.14 BTU 7. HVAC tonnage = Heating = 15455.07 : 12000 = 1.2879 BTU Cooling = 30490.14 : 12000 = 2.5758 BTU

1.0 INTRODUCTION 1.1 PROJECT INTRODUCTION
2A - Recording and measurement of 4 facings of external walls of chosen building In this project we were acquired to record and measure 4 facings of external wall of our current home as our site. Identifying the facings (N, E, S, W) of the 4 external walls of the room including its materials and measure the dimensions. Using 3 different times of the day which are 7 a.m., 12 p.m., and 5 p.m. Then calculate the heat transfer based on relevant examples given. After that, we were told to conclude and briefly reflect the identified the wall panel that us most critical/highest heat gain/most utilised space.
2B - Passive/Green Insulation Product Development After identifying the critical wall, we must come up with an original idea design solution to reduce heat transfer. The product has no constraints in terms of material usage, size, and it can be a permanent fixture or mobile as long as the usage is justified. The product can also have enhanced features such as noise control or/and light control.
1.2 SITE INTRODUCTION The house itself is a two-floor terraced house with 3+1 bedrooms and 2+1 bathrooms, a living room, and family room. Using my room as the site for the project, it is located on the ground floor of the house in Jakarta, Indonesia.

In results, Wall 3 has the hottest wall since it has an opening, because single panel glass window has lower R-values compared to the CMU. Even though wall 2 also has an opening, the area of the wall is much bigger compared to wall 3.
3.0 DESIGN PROPOSAL (2B) 3.1 DESIGN IDEA In order to reduce the heat in the room, the idea is to make reflective panels that can also act as a soundproof too. By doing my research, aluminium foil can be used and act as a reflective material. Hence aluminium foil is going to be the main material to reduce the heat inside the room for the product. They are cheap and easy to find.
WOOD FRAME
ALUMINIUM FOIL TOWELS
Many of the materials I am using were found around the house. Hence this project is eco-friendly by reusing the materials around and very minim budget.
The reason why I am using the materials : Aluminium is a material that has the ability to reflect 95% of the infrared rays which strike it. Not to mention that aluminium foil has a low mass to air ratio, which very little conduction can take place where only 5% of the rays are absorbed.
Towel is used in this product to act as soundproof because this product able to block or stop/reduce sound transmission. Using old towels to soundproof a door or window would not only help block noise from getting inside and outside the room, but it would also help absorb noise inside the room. Soundproofing using towels can undoubtedly be done, but it will not work as good as spending a bit of money to buy some actual soundproofing products. If you are on a tight budget or you want this as a temporary fix, then this might just be the solution.
Materials : -
Wood frame 300MM x 400MM X 120MM (I am using an old canvas and use the framework) Aluminium foil UHU glue Scissors Sewing kit (thread and needle) Yarn (you can use any type of rope that is available) Thrifted/old unused towel(s)
3.2 PROCESS OF MAKING PRODUCT 1. Iron the towel to get out any unwanted creases
By doing so, it limits the creases so that the cover will be smoother and neater.
2. Mark the towel so that it fits the inner part of the framework
Marking it correctly so that we can cut them to size which is 220MM X 320MM.
3. Making 5 layers
After marking them in the correct size, it then can be cut evenly. We need 5 layers of towel so that it can fill the framework perfectly. It is also the good number of layers for the towel to make it soundproof.
4. Sewing it together
To make sure the towels stay together, I sew it together using white coloured thread and needle. First, all around the outside, and then making some loops so that they do not sag later.
5. Measure the left-over towel for the cover part all around the wood frame
With final measurement of 400MM X 500MM, it is including the measurement to cover the whole back part and the wood that can be seen at the front.
6. Putting it together
Here, I use the UHU glue since it is a quite strong glue that can be used on both cloth and wood materials. Gluing it on every side and make sure everything is covered.
7. Cutting the exces
At this step, I cut all the excess so that it can be neater later on when we stick the aluminium foil at the back part.
8. Glue the 5 layers of towel to the middle
I am using the UHU glue again to stick the 5 Layers of towel to the inner part of the framework and gluing it to the inside part of the cover too.
9. Covering the front part with aluminium foil
I cover part that is not covered by the towel perfectly using the aluminium foil. The aluminium foil is the material that I am using to reflect the heat. Hence the heat in the room can be reduce.
10. Tie yarn on left and right side of the panel
Using yarn or other rope that can be found around to support the panels so that it can be hung up.
11. Final Product
This final product now can be hung near the window. The size itself can be customized according to your need.
12. Adding decorations
Decorations can be added just by clipping it to the yarn that is used to hang it up. Adding more yarn means there are more space for the decorations to be.
4.0 COST CALCULATION Most of the materials were available as it was not used anymore. Like the towel and the frame of the canvas. Thus only a few materials that I needed to buy before making this product.

5.0 CONCLUSION By doing this project I learn that the wall is crucial in insulating the heat, from the temperature outside and inside of the building. This way I can find the most problematic wall which insulate the least heat. Despite many ways someone can reduce the heat, making the reflective panel that can be used as a soundproof and decoration is the way that I decided to try and while I did the research, I learnt a lot of things. Like the materials, and how does each material work in absorbing or reflecting the heat to reduce the heat inside the room. At first, it was hard to do the calculations as I had to redo it many times due to my wrong understanding in some parts, but in the end I managed to try my best in doing the calculations. After doing that work, I understand more why the result is like that. In the end, this project is a great experience of learning. I had the opportunity to make my own prototype to reduce the heat and adding the soundproof in my room.
