SITE CONTEXT Current electrical wiring

SITE ISSUES

1. AIR CONDITONER PLACEMENT

The air conditioner position as in the current ceiling plan, should not be installed in the head and end of the bed. This is very important because it is the position where air is released directly to the body and head which may cause health problems.

If the air conditioner is not cleaned for a long time, the air blown out from the air conditioner will have moisture and germs as well. Which is one part that causes the respiratory system to malfunction. You may get cold or allergy easily.

2. EXCESSIVE HORSEPOWER OF THE AIRCONDITIONER

Currently, the horsepower of the AC in the current room is 1.5, that explains why the room gets unecessarily too cold when using the AC. The horspepower might be too big for the total heat load of the room, which will be calculate using the 7 step of the HVAC calculation in the folowing report.

3. INSUFFICIENT PLACEMENT and WATTAGE OF LIGHTING

The placement of the lighting in the current bedroom are ineffective and not comforting. When using

the working table, the shadow of ourself is blocking the lights that penetrate from the

center of the ceiling, and that's becoming an issue because I spent most of the time of my day sitting and doing works on the working table.

Another issue that come to the surface is that the wattage of the ceiling light that are too big and not used efficiently for the room therefore, some replacement of thelightings are required

SITE CONTEXT New proposed electrical wiring

SOLUTIONS

1. POSITION REPLACEMENT FOR AIR CONDITONER

The installation position should be in the long wall position. So that the cold air can distribute to the left and right of the room evenly. And not installing air conditioners on all electrical devices because while the air conditioner is working often have water problems with air dripping. If there is electrical equipment at the bottom will damage electrical equipment. It can cause an electric shock accident. The most suitable position for installation in the bedroom is the side wall that is perpendicular to the bed. The wind direction from the machine blow across the body while sleeping. It may be installed slightly towards the end of the bed and will help reduce the risk of allergies or the respiratory system.

2. BRINGING DOWN THE HORSEPOWER OF THE AIRCONDITIONER HVAC Calculation

As we can see on the above 7 steps of HVAC calculation that the based on the total heat load, the AC unit required are only 0,8 which are rounded to 1 Horsepower. This explains the room is too cold while operating the air conditioner. It will improve our sleeping/activities qualities as weel as reduce down the energy used by half

RELOCATE THE LIGHTING POSITIONS AND THE WATTAGE

To optimizing the lighting used, we must know which position are the

most

effective.

Lights

should

positioned

around

the

perimeter of the room order for the lights to be able to every sides and corner of the space. For this floor plan, I figured out that we only need 2 pieces of downlight lights because of the size of the room

As we can see on the new ceiling plan that the placement of both recessed light are placed right in front of the closet and near the working desk & bed. This coveres up the majority part of the bedroom

Another solutions to the issue regarding the lights on the working desk, I came up to the solution which

solving

the

problem

well

adding

another features to bedroom. Track lighting works best in a

minimalist bedroom with high ceilings. It

will help to decorate the interior of the bedroom.

Unlike another light that the light fixtures are fixed to the ceiling or wall, with track lighting fixtures, that problem is eliminated as the lights can be moved to suit your tastes.The users can move it toward the working desk as well as towards the bed for night reading, so it will have a double function. Also, with the distance from the light to the objects, it allows the light to difuse and become softer while pointing towards the object and will not likely to cause eye strain.

Questions of the day !

Why not using regular desk lamp? that if we are exposed to direct

Studies have shown

lighting for too long, it

can actually damage our eyes by increasing the risk of eye diseases. It cuts down on glare which is one of the main factors causing tired eyes and eye strain.

ENERGY USED CALCULATIONS

As shonw on the table above, the energy used for old design per month are

341,34 kW,

resulting the total bill to be cost RM 136,50. It is mostly because of the samsung air conditioner and LED ceiling light.

After solving the issues, we can see on the table of energy used for new design that changing the air conditioner horsepower and lighting wattage affect the monthly bill to RM 104,10.

CONCLUSION

Although it may sounds simple, choosing the right

lighting and VAC area bit tricky and crucial

because we have to consider all posibilities that might be faced later. The comfort of the user are also important in this matter because they are the one who experiencethe space.

By conducting this project, I have learned a lot about how to choose the perfect lighting and ventilation while considering the cost and energy used,

Based on the calculation and table above, the wall which have the highest Q is Wall 2 with 3100,19 BTU/hr at 12 p. m. The q value is much affected by the area. But due to the fact that Wall 2 is nealy 2 times bigger than Wall 1, it can be concluded that if both of them have the same area, then Wall 1 with 2118,70 BTU/hr, will have the highest heat absorption eventhough the Q value of the Wall 2 is higher .

Conclusion

By doing this project, I am able to identify the calculation and formula to be proceeded to find and compare the heat transfer of each wall of the chosen space. In which, later will be used as an experiment to find the solution on what product will be made in order to reduce the heat transfer and the other features such as sound proofing and can be used as a cushion. In making the product, it's allowing me to come up with the originality of the design and ideas,

PART 1 (a) Site Study and Re-design Kitchen

Site Study In current situation, there are not much different activities

in the kitchen while on the MCO

compared to before MCO. because we rarely buy take-away food. The kitchen activities starts in the morning around 6 a.m. Since all of our family are coffee drinker, she

make our coffee

traditionally by pouring hot boiling water in a glass with coffee powder in it.

Then she starts to cook breakfast until 9.30 am. In our family we dont eat lunch, only breakfast and dinner. For dinner, our family chef reheat the meal that were made in the morning, which have been divided into two

portions, for breakfast and dinner. Resulting in

approximately 4 hours for the kitchen operation per day.

Kitchen situation while preparing breakfast

As we can see from the photo above, the main working spaces in the kitchen are on the stove area and the sink area. The ingredients are placed on the countertop in between stove and sink.

Current kitchen layout plan

During this time of period, we spent most of our time inside the house, thus we tend to develop new hobbies, one of them is baking. Especially me and my mom. Mostly we bake in the evening because it is cooler that in the afternoon, since there are the kitchen

natural ventilation in

Kitchen electrical and lighting plan

As in the electrical and lighting plan, theres one ceiling light in

the kitchen as well as

in the

pantry/dining room. This might raise some lighting problem.

Kitchen water supply and plumbing plan

Based on the water supply and plumbing plan, we can see that they have distributed properly and accurately, thus there will be no additional plumbing pipe. But there might be changes on the path pf the plumbing pipe, which will be analyzed on the following page.

Re-design Kitchen

Stove Placement On the new kitchen design layout, the first thing that I was move the position of the stove. On the previous layout of the kitchen, it can be seen that the stove is placed in front of the window ventilation, which might raises some problem. Based on the experience of the family chef, the window will likely to be covered with a film of oil, spatter, and steam drips, which will take more time and effort to clean. Moreover, if the window glass is exposed to the heat in a long period of time, the window glass will likely to break.

Sink Placement The change of place of the stove resulting in the change of place of the kitchen sink, which are moved in front of the window.

makes an effective use of the entire space. This is because there will be no cabinets on top. Resulting in more spacious space that in the previous kitchen layout, which have the cabinet on top of the sink.

Coffee Station

Based on the interview, I figured out that it is a necessity for the family to hace a coffee station, emphasizing that all of the family member are a coffee drinker, thus there will be no fuss in preparing the coffee, because we all can enjoy the coffee anytime we want, without preparing and washing the coffee equipment repeatedly. The user will also be able to enjoy the view outside the window through the dining area.

Refrigerator Placement

On the previous layout of the kitchen, the refrigerator is blocking the pathway and sight to the window. Moreover, the power usage of fridge are inefficient since the family does not really use the fridge. Therefore I propose the placement change of the fridge as well as the replacement of usage model.

the refrigerator to the lower power

PART 1 (b) Designing and Justification of Building Services Selection & Location

Electrical, lighting and VAC

The change of the lighting placement are based on the experience that the cook's faced such as blocked light, and insufficient lighting. Therefore, I propose a

new location of the lighting right

above the work surface (kitchen and pantry countertop) and

it prevents the user's body from

blocking the light when he or she stands at the counter working. It also throws light directly into open drawers. Another popossal is to add LED lightstrip under the countertop on the stove area to provide sufficient lighting Other than lighting, I also proposed a new outlet at the coffee station so that the user can operate the coffee machine.

The needs of the cooker hood are essentials for every kitchen. It will remove odors, smoke, grease and other pollutants that are released into the air while cooking and also easier in cleaning because it will prevent the growth of bacteria and mold.
