DISCOMFORTS & PROBLEMS Problem 1: Insufficient Power Outlets The sockets are minimal and one of the sockets placement is behind the bed.

Poor placement of the socket resulting in use of extension while some electrical appliances can’t be used in an extension. For example, a hair dryer and other electronic hairstyling tools as it produces heat and should be using a wall outlet.

Problem 2: Poor Lighting The direct light from the window is too overwhelming to glare at when studying at the table even with the curtain closed. It has been a health concern as the excessive lighting through the window causes pupil constriction and eye strain.

Problem 3: Insufficient Lighting Another discomfort is the current lighting placement is only above the bed and not enough used for working and study space. In this case, the user may experience drowsiness or lose their sense of motivation, which can result in an overall reduction of work productivity.

Problem 4: Placement of Air Conditioner The air conditioner placement is not ideal for the working space. In addition, the air conditioner has been in use for over 10 years. Therefore, there are some leaks and drips sometimes and it may spoil the desktop.

Problem 5: Inadequate Desk Space The desks are placed in a restricted place and are beside the bed. In this situation, it can impact a user’s productivity and efficiency, as well as general wellbeing at work or study.

Problem 6: Lack of space for walkway The cabinet has taken up the space for the walkway, it used to be placed at the desk area. However, it is now moved to the other side and now it should be removed and move my bed to the current cabinet side.

BENEFITS/SAVINGS/ECO-IMPACT Benefits: ● LED lights use 75% less energy than incandescent bulbs. In addition to that, power plants aren’t working as hard or producing as much pollution. ● LED strip lights last a long time. ● It generates much less heat than the current lighting. Therefore, It is much safer to leave LED lights on because they won’t get hot enough to start a fire.

Savings: ● Long lifespan (50,000 hours), reducing the cost over time ●

It doesn’t use much energy, they don’t cost a lot to maintain

Eco-Impact: ● A long lifespan makes this ability to reuse and reduce trash. ● Less energy usage

ASSIGNMENT 2A INDOOR COMFORT DESIGN AND ‘INVENTION’

Floor Plan and Wall Allocation

Introduction The selected room is a bedroom and the walls are divided into 5 different sections as all of their exterior temperatures are different while the interior temperature will be assumed as the same. The exterior temperature will be collected using weather forecasts in three different time slots, 7 a.m., 12 p.m. and 5 p.m.. The interior temperature will be the air conditioning temperature.

Conclusion As stated in the calculation above, wall 2 has the highest heat transfer among the other three walls during the recorded hours. Wall 2 has two windows which is a great conduction material which results in having the greatest heat transfer.

ASSIGNMENT 2B PASSIVE/GREEN INSULATION PRODUCT DEVELOPMENT

Heat Insulation Panel Product Description This is a heat insulation panel with three layers of material which are felt fabric, foam board and bubble wrap. The wood panels on the front are aesthetically pleasing.

Product Location It is located at the smaller window in the bedroom (referring to 2A wall 2). It is located at the specified window because it is the work space where there’s too much light glare through the window and the curtain isn’t covering much light.

Product Materials & Dimensions Each panel's dimension: 450mm (L) x 18mm (W) Material: ● Foam board ● Felt fabric ● Bubble wrap ● Wood panels

Building Model Instructions

Method of installation ● Using velcro to stick on the wall ● Then attach the panels to the wall Features ● Can be pin up for notes and photos ● Easy and fast installation

Cost of Materials

Steel Hinges = RM 16 Wood Board = RM 3 Nicora Paint (20ml used) = RM 5 Brush = RM 2.50 Bubble wrap = RM2.80 Felt modeling = RM 50 Velcro tape = RM 15 Foam board = RM 7

Total cost: RM 101.30 Cost per panel: RM 50.65

Design Value Total Amount = RM 1275.10 Average Market Price = RM 1276.10 / 24 = RM 53.17 Design Value = RM 53.17 - RM 50.65 = RM 2.52

Reflection The heat insulation panels that I’ve designed have proven that it absorbs the heat from the exterior and it blocks out almost all the sunlight. However, there’s a mistake I have made during the model making. I did not glue the bubble wrap well enough for the velcro and hinge to attach. When I tried to remove it the first time, it almost broke or tore off. Next time, I will use a glue that actually sticks to the bubble wrap and the poly foam board instead of using white glue or super glue. After collecting the market price, I have gathered the amount of design value which is RM 2.52. Although the value is not high, there’s still some potential to be sold on the market.
