Chosen Space : Bedroom

DISCOMFORTS/ PROBLEMS Problem 1: Bed light too dim and hard to replace Sometimes I would off the main lights and only on the bed light for me to continue to do my work while my sister is sleeping beside me, but the one of the lights burned out causing it to be darker, but at the same time if the lights are as it is, it might be a little too bright if I were to go to sleep. Solution for it is to change the fluorescent lighting to LED controllable strip light with remote.

Figure 1.1 One part of the existing bedlight has burned out causing the current lighting to be darker.

Figure 1.2 The Lux Meter app measured the total lux around the bed with just the bed light.

Problem 2: Only single power outlet at desk The study desk has only one power outlet, which is inconvenient because I frequently need to charge multiple appliances at the same time, especially when working on assignments. Instead of one outlet, I would change it to three to reduce the safety hazard.

Figure 2 The use of extension cable with multiple power sources on at the same time might cause short circuit or electricity overload.

Problem 3: Toilet ventilation (window) too low The current window is perfectly big enough for air flow to ventilate through the toilet, but the only flaw was that it was situated really low where the neighbors at the back could look into the toilet while showering.

Hence, window should be placed in a higher position to avoid such accidents.

Figure 3 The height of the window is around my shoulder where it will get visible to the outside once I step further away from the window under the shower mixer.

Problem 4: Air Conditioner too close to wardrobe + weak horsepower The existing AC unit was placed too near to the wardrobe, causing half of the cool air to be blocked by it when I set the flaps to the right blowing towards the desk area, as well as it’s too far from the left making the cool air unreachable to the person sleeping on the far left of the bed. Other than that, the present AC unit has only one horsepower. It is insufficiently strong, the existing unit will be unable to effectively chill the space no matter how I reposition the AC unit. As a result, an upgrade to a greater horsepower will be required as well.

.

Figure 4.1 AC unit placed really near to the side of the wardrobe.

Figure 4.2 A close up shot of the old AC unit from the angle of the desk area.

Problem 5: Natural lighting too dim around desk area The current window is small as well as it’s facing south causing only little sunlight to shine through, in addition my desk is situated far away from the window which I had to on my room light everytime I’m doing my work. It is wasteful in electricity hence it will be wise to expand the window and also to move the desk towards the window area to fully utilize the natural light and save electricity during the day .

Figure 5.1 The Lux Meter app measured the total lux around the desk area with just natural lighting.

Figure 5.2 The Lux Meter app measured the total lux around the desk area with down lights switched on.

CONCLUSION Based on the calculations, the north wall has the highest heat transfer rate on all 3 hours recorded. Although the area of the wall is the smallest compared to the other three, the fact that its located next to the balcony facing directly at the open air makes it more prone to heat change compared to the interior walls. The South and East walls also transfers heat from time to time whereas the West wall has the same temperature throughout the day, thus no heat transfer occurs.

TASK 2B PASSIVE/ GREEN INSULATION PRODUCT DEVELOPMENT PRODUCT SKETCHES

PRODUCT DESCRIPTION This is a prototype heat insulation panel meant to keep heat out of a space. The following are the suggested heat insulation panel's design intentions: • • • •

To minimise thermal heat transfer Simple to set up A ordability and convenience Materials are easily obtained and lightweight

ff

In accordance with the design intentions stated above, this heat insulation panel is intended to apply heat insulation.

MATERIALS One of the most important elements of the materials used for my product is transparency, as the product is to be placed at the sliding door area. I do not want the product to obstruct the sunlight from coming in which will make the sliding door lose its purpose, hence 90% of my materials are transparent, except for the frame which requires to be solid enough to hold the soft materials in the centre. Materials used are listed below: •

Bubble Wraps. Bubble wraps serve as a good insulator because of its design which has small air pockets. Because the base material for bubble wraps are plastic, it heats up quickly.

•

Transparent PVC Sheet. With its excellent thermal insulation properties, PVC sheets are a cost-effective solution to reducing heat transfer.

•

Tinted Acrylic Glass. Tints will reduce the amount of heat and light that can pass through, thus reduce the transfer of heat and improve comfort.

•

Styrofoam Board. Styrofoam board insulation is a great alternative insulation that is in most of our homes. It has a higher R-Value per inch of thickness, it’s resistant to moisture and is easy to work with.

•

Acrylic Panel and PVC Board. Solid enough to hold the soft materials and act as railings.

METHOD This product consist of 3 layers of di erent materials of di erent degrees of insulation. With the tinted acrylic glass at the outer layer followed by the bubble wrap layer and nally the transparent PVC sheet. The purpose of enabling these di erent layers to be removable and installable is so that the heat insulation panel can be adjusted according to the weather outside or room temperature.

INSTALLATION Velcro strips are sticked on each lines on the sliding door grill as well as the frame of the heat insulation panels so that it can be sticked/ placed wherever area preferred

PROCESS OF PROTOTYPE MAKING

1. Styrofoam board are cut into di erent size of frames

ff

2. PVC panels are cut into 300mm long for railings and then to be sticked on both up and down of the styrofoam board using silicone adhesive

3. Inner solid acrylic frame from parent’s factory are to be used with the existing cutting design

4. Bubble wraps are cut into the size of the rectangular hole and later on sticked at the back of the frame with white glue

5. Repeat step 4 with transparent PVC sheet and sticked at the back with double sided tape

6. Tinted sheet are sticked onto the acrylic glasses

7. Spare PVC panels are cut into thinner pieces to create groove for railing

8. Sides are sticked with a separate piece of styrofoam board with opening to allow space to insert and remove the 3 panels

9. Opposite sides are cut with matching shapes to create joinery between panels

FINAL PRODUCT (PICTURE)

INTERNAL WALL TEMPERATURE (AT 12 PM NORTH WALL SLIDING DOOR)

Without panel : 37.8°C

With panel : 33.5°C

RECEIPT/ COST Most of my materials are recycled/ found at home. Source of materials are listed below: •

Bubble wraps are obtained in parcel from online deliveries during MCO

•

Acrylic sheet are spares from my parent’s factory

•

Both tinted acrylic glass and styrofoam board are leftovers from previous projects

•

Transparent PVC sheet is obtained from home

One panel = RM 0 Size of panel = 450mm x 220mm = 1.07 ft² Sliding door area = 56.16 ft² Approximate no. of panels = 56.16 ft² / 1.07 ft² = 53 panels Total cost = 53 panels x RM 0 = RM 0

DESIGN VALUE

Total amount = (45 + 50 + 40 + 45 + 50 + 60 + 80 + 100 + 100 + 100.10 + 50 + 50 + 40 + 55 + 40 + 40 + 29 + 50 +3 0 + 20 + 60 + 60 + 50 + 50 + 20) RM = RM 1315.10

Average market price = RM1315.10 / 25 = RM52.60 DESIGN VALUE = RM52.60 - RM0 = RM 52.60

REFLECTION After hearing Ms Sharon’s feedback on others, I realised I made a mistake on using black coloured acrylic panel frames and PVC board railing as my materials thinking that absorbing heat is an element of an insulator and it reduces heat transfer but in truth it’s the opposite. Nevertheless, the design value showed that my panel has potential to the accepted and sold in the market, as well as it proves e ective when tested out the temperature of the sliding door with and without the panel, showing a decrease in

ff

temperature, hence proving that my prototype overall is still considered successful.

FINAL PROJECT - DESIGN OF BUILDING SERVICES (IAD III INTEGRATED)

NAME : ASHLEY TEW LI WEN STUDENT ID : 0343533 LECTURER : MS SHARON TEH AI PING

TASK 1(A) : SITE SELECTION & QUALITATIVE DESCRIPTION OF INCORPORATED BUILDING SERVICES BUILDING INTRODUCTION & FUNCTIONS The selected area for this assignment is located at the rst oor of REXKL as assigned from IAD III. The selected oor serves as an interactive space for audience to introduce the art of puppetry, giving them an insight to the types of puppets used around the world, and o ers diverse learning opportunities and workshops for all ages. Below is a list of spaces in the site and its perspectives, together with annotations of the lightings, VAC, basin and water closet.

Spaces in the site 1. Ticket and arcade area LED Light Tube

Perspective 1 : Ticket area

Perspective 2 : Arcade

LED Lights

The ticket area and arcade are the prologue of what I am going to promote in my selected space, hence I chose LED lighting as it provides me with more freedom in terms of shapes and sizes of the lighting to make the space more interesting and intrigue the visitors as they come in. LED lightings are used in all light sources from the ceiling and the steps to the signage and directional lights to ensure the space is well lit.

2. Administration O ce Pendant Lights

Wall Mounted Duct

Perspective 3 : Administration O ce

The o ce is a casual space restricted for sta s only, therefore no fancy design is required in this space. I would have used normal down lights but the ceiling design would probably blocked most of the light path, hence I changed it to pendant lights so that it hangs down over the ceiling and no lighting restriction. For air conditioner I have used the wall mounted air conditioner because its the only air conditioner design that doesn’t require too much space and ts right into the wall between the ceiling and the glass panels.

3. Pop-up capsule

Perspective 6 : Interior of female toilet

Water Closet

Perspective 7 : Inside toilet compartment

Toilet uses LED lightings as well with wall mounted propeller installed in both sides of the toilets to allow ventilation throughout the space. Basin is in typical ceramic white, with white water closet and sh as well as bidet at the side.

5. Exhibition area LED Lights

Perspective 8 : Exhibition

fl

The exhibition area serve the same purpose as the ticket and arcade area, hence the design intentions are similar. LED lightings are also used in every light source.

6. Rest area Down Lights

Ceiling Mounted Cassette

Perspective 9 : Rest area

Rest area are exclusively for the sta s thus design are kept in a minimalistic way. Simple cool white down lights were mounted on the ceiling, together with ceiling mounted cassette unit for A/C.

7. Manikin Tower with workshops LED Lights

TASK 1(B.1) : DESIGNING AND JUSTIFICATION OF BUILDING SERVICES SELECTION AND LOCATION LIGHTINGS Pendant Lamp with LED Bulb Location : Administration O ce

LUXRITE A15 LED BULB

Lighting for Administration O ce : 600 lm/ft²

ffi

The administration o ce is considered near to the big oor to ceiling window, hence lower lumen is only needed in that space as it has also some additional natural lighting. Still 6 pendant lights will be placed on the ceiling for more comfortable work environment if : the weather goes bad with no sunlights or when it’s near to night time. 4000K is chosen to suit the need of an o ce.

LED Down Light Location : Rest Area

Lighting for Rest Area & Pop-Up Capsule : 1100 lm/ft² Since the pop-up capsule is deep into the space with little sunlight coming through as well as the rest area is in an enclosed space with no windows or connections to the outside, higher lumen value is needed to light up the space. A 1100 lumens with 4000K light is chosen. A total of 9 down lights will be placed at the pop-up capsule and 4 down lights will be placed in the rest area to distribute the light rays.

LED Light Tube Location : Ticket & Arcade Area / Pop-up Capsule / Public Toilet / Exhibition / Manikin Tower

Ceiling Lighting for Ticket & Arcade Area / Public Toilet : 2000 lm/ft² The main reason of putting such a high lumen value lighting at the ticket and arcade area when the space is so close to the big oor to ceiling window is because it is one of the most crucial spots, hence it’s necessary to ensure enough lighting can illuminate the space during the night.

Public toilet near the pop-up capsule is enclosed with no window so there will be no natural light to enter the space, hence higher lumen is also required in the area.

Wall & Floor Lighting for Ticket & Arcade Area / Exhibition : 800 lm/ft² The wall lighting for these spaces are solely for decorative purposes only, together with the oor lighting at the arcade and the outside of the o ce serves as a pathway guide and only needed to be bright enough to illuminate the steps ahead o them, therefore lower lumen is only required.

Lighting for Manikin Tower : 5000 lm/ft²

fl

ff

ffi

fl

The tower is the main focus of the space, hence high lumen value is needed in incorporating the lightings into this massive structure.

LED Circular Light Location : Exhibition Area

Lighting for Exhibition : 2000 lm/ft² For the exhibition area although there will be tons of windows around the big hall, it is actually located deep inside with a shade/ extension from above hence the space with be dimmer. For this reason I have decided to use a higher lumen value lighting as well because it’s also the only ceiling lighting available in that area.

VAC Wall Mounted Duct Location : Administration O ce

Air Conditioner Sizing Calculation for Administration O ce Room area = 4125mm x 6075mm = 269.74 ft² Btu/hr = 269.74 ft² x 25 = 6743.5 Btu/hr Ceiling height = 3590mm = 11.78 ft (To add 1000 Btu/hr for each foot if ceiling is over 8 feet tall) Btu/hr = 3 ft x 1000 Btu/hr = 3000 Btu/hr Estimate occupants : 6 Btu/hr = 6 people x 600 Btu/hr = 3600 Btu/hr Estimated heat from electrical equipment Desktop PC : 600W // Lightings : 42W // Water dispenser machine : 886W Total : 1528W Btu/hr = 1528W x 3.415 = 5218.12 Btu/hr Total Btu/hr = ( 6743.5 + 3000 + 3600 + 5218.12 ) Btu/hr = 18,561.62 Btu/hr

Horsepower = 18,561.62 Btu/hr ÷ 9800 = 1.89 HP

Ceiling Mounted Cassette Location : Rest Area

Air Conditioner Sizing Calculation for Rest Area Room area = (8075mm x 3950mm) + (3450mm x 5911.88mm) = 562.87 ft² Btu/hr = 562.87 ft² x 25 = 14071.75 Btu/hr Ceiling height = 3732mm = 12.24 ft (To add 1000 Btu/hr for each foot if ceiling is over 8 feet tall) Btu/hr = 4 ft x 1000 Btu/hr = 4000 Btu/hr Estimate occupants : 6 Btu/hr = 6 people x 500 Btu/hr = 3600 Btu/hr Estimated heat from electrical equipment Refrigerator : 550W // Lightings : 38W Total : 588W Btu/hr = 588W x 3.415 = 2008.02 Btu/hr Total Btu/hr = ( 14071.75 + 4000 + 3600 + 2008.02 ) Btu/hr = 23,679.77 Btu/hr Horsepower = 23,679.77 Btu/hr ÷ 9800 = 2.42 HP

ffi

The calculated horsepower requirements for the rooms are greater than 1.5 and 2 horsepower respectively. Rounding up to the nearest commercially available unit, these rooms should install both 2 and 2.5 horsepower to maintain a cool temperature when the room is in heavy use and not less as it will not be ideal and su cient to cool the entire room during hot weathers.

TASK 1(B.2) : QUALITATIVE AND QUANTITATIVE JUSTIFICATION OPERATING HOURS : Weekdays 12PM - 5PM // Weekends 10AM - 8PM Considering the operating hours above, weekdays will be open for 5 hours whereas weekends will be open for 10 hours. All lightings will be on the whole time during operating hours, except for the administration o ce where there will be a one hour long lunch break for 7 days per week, so the room services will not be used in that duration of time. Another would be the rest area, where it will be only used for an hour during weekdays and two hours on weekends. Both toilets' ventilation fans will run continuously to provide appropriate air ow and minimise overpowering odours.
