SITE PLAN
FACADE N
NORTH-EAST ELEVATION
STUDY UNIT S
The house of the current study is located on the most top floor of the building. Therefore, the solar penetration effecting the unity would come from the North-East windows and South-West windows, also from the roof. However the wind are supposedly easier to reach the house due to it being on the upper floors. SOUTH-WEST ELEVATION
The South-West windows usually gets more wind movement.
SUN PATH The sunpath diagram shows that the North-East windows would receive the morning low light while the South-west window would receive the hotter sunlight. The rooms are located on the East of the unit while the common space which is the living room is located on the West. In the following study, It would show the effects it has towards the energy usage and the occupantional behaviours.

WINDOW From the graph it shows that FAN almost half of the applicances in the house are related to the ventilation category. The kitchen apllicances uses more energy than the lighting appliances as most of the lighting devices uses LED. This proves that LED lights are efficient in energy consumption.
AIR-CONDITIONING
All the private rooms are fully equiped with air-conditioning making it the main used device for ventilation. The living room is not equiped with air-conditioning, even though it has the highest temperature in the house. Therefore, fans and portable airconditioning and windows are used in the living room area.

LIVING ROOM
MODERATE
Full height windows open up towards the West side making the space very uncomfortable during the afternoon solar penetration.
LED lights, televisyen, ceiling fan, table fan, portable air-conditioning Due to the heat during the day, most occupants avoid being in the area rather staying inside the rooms. When being in the space, occupants lack of consideration towards energy saving will tend to switch on all the cooling appliances to achieve a better thermal comfort.

THE OVERVIEW The average energy consumption are significantly higher during the weekdays as the occupants are using more appliances such as the laptop for online classes and meeting which will significantly increase the amount of cooling devices neeeded to cool down the laptop and the space. The occupants are also scattered around the house to use the individual rooms to avoid distraction resulting in mulitple devices used at once. The average energy consumption are lower during the weekends as the occupants are usually chilling in the living room without using any airconditioner. Most weekends the occupants spend time sleeping and also would go out for dinner.

Appliances and Occupants Usage Behavior
towards the dining space where is also used to have online classes.
LED lights, wall light, ceiling fan Space connected to the living room area makes inneficient occupant behaviour by switching all the cooling appliances on. During hotter days, the curtain at the living room area would be drawn down to create barrier from the heat however this cause all the lights to be switched on as the balck out curtains would block all the light to enter.
HIGH
Space is fairly shaded but heat from cooking can results the heat to radiate to other spaces making it only uncomfortable when cooking.
LED lights, refrigerator, water dispenser, oven, rice cooker Although the space is only needed to cook two times a day, the energy consumption by the appliances are mostly higher as as it runs 24 hours a day to keep the food in the refrigerator fresh and the water in the water dispensor ramining hot and cold.
LAUNDRY AREA
LOW
A comfortable space during the afternoon because the space faces the East making it protected from the afternoon solar penetration.
LED lights, washing machine The washing machine would run few times a day depending on the amount of laundry needed to be washed. During the lockdown season, the washing machine would run multiple times in a day every time an occupant comes back home from the outside.
MASTER BEDROOM
MODERATE
Big windows only covered with curtains towards the West side is uncomfortable during late afternoon till evening solar penetration.
LED lights, ceiling fan, air-conditioning, phone charger Occupants in the master bedroom would switch on the air-conditioning every night until the early morning. Even so, the ceiling fan would also be switched on with the air-conditioning during hotter days and when the afternoon solar penetration increases.
BEDROOM 1
HIGH
Small window opening towards the East side, creating a humid environment and poorly ventilated.
LED lights, ceiling fan, air-conditioning, phone charger, desktop Due to the humid environment, the occupant would usually switch on the air-conditioning towards early morning and leave the ceiling fan continuous on to better ventilate the space. The light are switched on sometimes because the small window in the room could not light up the space enough.
BEDROOM 2
MODERATE
Big windows towards East side, making the space comfortable without excessive air-conditioning except during hotter months.
LED lights, ceiling fan, air-conditioning, phone charger, desktop The occupants in this bedroom are more usage friendly as the ceiling fan are used more then the air-conditing, because the occupant does not always sleep in the freezing cold. Therefore, the constants spinning ceiling achieve a comfortable thermal spaces.

DESIGN PROPOSAL ISSUE - DARK AREAS IN THE HOUSE THAT NATURAL LIGHTING DOES NOT REACH
How much light does a sun tunnel produces? A 10-inch sun tunnel offers equivalent of 3 100-watts bulbs, which a 14-inch sun tunnel can brighten up a space up to 300sq
SOLUTION - TWF flexible sun tunnel installed into tile Sun tunnels installed on the home’s roof catches the sunlight which is reflected down a rigid or flexible sheet metal tube in the attic before shining on the diffusing lens in the room’s ceiling. Solar tubes are effective to prevent UV rays from entering the space as it is blocked at the solar dome before entering the tube.

It is energy efficient because light is captured and diffused into the home, unlike a direct sunlight that allow up to three times than a regular window. Benefits Brings natural light into a property. Cuts lighting costs.

ISSUE - UNBEARABLE HEAT GAIN DURING THE AFTERNOON SOLAR PENETRATION SOLUTION - LOW-E glass The main common space which is the living room are usually avoided by the occupants because of the heat during the afternoon till evening. This also creates another problem which is, the occupants would retract to individual rooms and switching on each hvac system. This will increase the ventilation cost. The South-West facing window allow high solar penetration during afternoon.
Filter up to
30% -70% of solar heat
ISSUE - Inneficient occupant consumption SOLUTION - HVAC system sensors A bluetooth thermometer that can be connected to multiple devices to control the energy usage. This could help to reduce usage when it is not being used at the moment. Temperature sensors
Humidity sensors To maintain a preset air temperature, an HVAC system will typically have one or more interior air temperature sensors, an ambient (outside) air temperature sensor, and possibly one or two solar load sensors..
Humidity sensors are capacitance sensors that measure the amount of moisture in the air. The information from the sensor both regulates the volume of air projected onto the windows to reduce misting and manages the humidity levels
NARROW AND RECTANGULAR HALLWAY Darkest area in the home are the hallway that connects private rooms to the common area. However due to the space being out of reach from any window, the space becomes very dark and unpleasent. Although lighting only makes up 10% of the monthly bills, the home is not fully equipped with a lot of lighting appliances making a lot of the spaces remain dark. Therefore, a sun tunnel would be a good addition for the home as it can also reduce about 30% of the lighting cost. The light from the sun tunnel could also diffuse the light into the dining area The sun tunnel does not increase the heat gain in the space therefore no addition cooling devices needed to be use to cool down the area.
30% reducing lighting cost
