This project's chosen location is the master bedroom of the unit, which also happens to be my bedroom.
My bedroom is divided by 3 area, bed area, study area, and wardrobe. In this bedroom, there is a window that faces north. The sunlight is so bright in the morning and afternoon that I don't need to turn on the lights. According to the picture, the bed area has 644 lux in the afternoon, which is higher than any other area (as shown in figure 1.1). Meanwhile, the study has 439 lux, and the wardrobe has 274 lux (as shown in figures 1.2 and 1.3)
Figure 1.1
Figure 1.2 Figure 1.3
When it's night and the lights are switched on, the bed area has 50 lux (as shown in figure 1.4), the study area has 13 lux (as shown in figure 1.5), and the wardrobe area has 9 lux (as shown in figure 1.6).

The light fixture in this bedroom is surface mounted light (as shown in figure 1.7) and fluorescent tube light that located below the floating shelf at the study area (as shown in figure 1.8)

The air conditioner in this bedroom is Electrolux ESM09CRD-C1 1.0 HP (as shown in figure 1.9). The air conditioner is often turned on for 10 hours every day.

The first issue with this room is that the lighting is weak, so even when the light is turned on, it does not appear to be very bright (as shown in figure 2.1).
Figure 2.1
The second issue is the lamp is not in the centre of the room, the light is not distributed evenly around the area (as shown in figure 2.2).
The third issue is there is no lighting in the wardrobe area, so I can't see clearly in there if it becomes dark (as shown in figure 2 3).
Figure 2.3
The fourth issue is that I rarely use the ceiling fan. Because this room has a window, I don't think a ceiling fan is necessary because I can simply open the window to get some fresh air (as shown in figure 2.4)
The fifth issue is the location of the air conditioner. The air conditioner is currently facing the bedroom door, so the wind is blowing there rather than throughout the room (as shown in figure 2.5)
The change in this room involved adding, removing, and relocating items that had previously been mentioned.
The first one is changing the lighting from surface mounted to LED round downlight. The light that will be used is Philips LED 10W 6” Meson Round Downlight.
Figure 3.1
3.2
The second solution is to relocate the lamp to the middle of the room (as shown in figure 3.3). The light that would be emitted will be more equal if the light is moved to the centre.
The third solution is adding a LED round downlight at the wardrobe are (as shown in figure 3.4). The addition of a light fixture in the wardrobe area will make it easier for me to see the wardrobe, especially at night. The light that will be used is Pila 12W 5” Round LED Downlight (as shown in figure 3.5)

Figure 3.5 Specification:
The fourth option is to remove the ceiling fan. As previously stated, I rarely use the ceiling fan, therefore it's best to remove it. Furthermore, instead of a fan, an LED light will be installed in that location (the second solution). The last solution is to move the air conditioner to the opposite wall (as shown in figure 3.6 and figure 3.7). The wind will fill the entire space at that position.

Based on the calculations above, the air conditioner required for this room is a 1.5 hp unit. As a result, the air conditioner will be replaced with a 1.5 hp unit. Air conditioner that will be used in the room is Samsung 1.5HP S-Essential Air Conditioner (as shown in figure 4.1).

Through this assignment, I learned that there are many ways to minimalize heat transfer. A lot of simple materials that can be used, even a bubble wrap. I amaze with all of the prototype that my classmates made because all so cool and out of the box. In my opinion, Janelle prototype is really good. I like the ideas and the visual of the product.
When I made this product, there is an error that made the magnet tape is not attach to each other. After thinking some solution, I put the round magnet in each edges and in the middle. I personally think that this assignment its really useful and fun. Students can share their ideas and skills.

This building is located at Tamarind Square, Cyberjaya. The purpose of this building is to sharing awareness about fast fashion There will be several activities to reduce fast fashion, one of which is upcycling clothes from worn clothes.
Selected Area of Site: Level 4 (Thrift Store)
Specific Activities and Building Services of Selected Area:
Thrift store is an area for selling second-hand clothes. As a clothing store, this room need to have a proper lighting and also air conditioner since it’s a indoor area. Inside the thrift store, they also have a toilet and fitting room. The fitting room used for the visitor to try on the clothes that they want to buy.
LED downlight will be used at all the area, but with a different specification per room.
For the thrift store and fitting room LED Downlight that will be used is downlight with 900 lumens and with colour temperature 4000k cool white. The reason why I choose white colour is because the space itself is a clothing store, lighting will affect the colour of the clothes. So, it will be better to use the white colour one.
For toilet, LED Downlight that will be used is downlight with 940 lumens and with colour temperature 3000k warm white. I decide to use the warm white because warm white lighting is calming and relaxing, it is best for bathrooms
