01 Presenting Room Selected

3

After a long consideration about the room selection, finally I chose my own apartment unit, that is: 33 Sheppard Avenue East, Suite #2705, to be studied further and deeper in this lighting assignment.

The careful thought for the selection of the room to be `further analyzed includes several concrete reasoning. First, by studying the room where I reside, I would be able to deeply understand and experience the advantages and disadvantages about the lighting system in serving different activities in different rooms. I know exactly the drawbacks of the system that can lead me to a more concrete analytical study about the room. Moreover, the ease of access to measure everything correctly and look at everything closely would give me a high quality analysis of the project; I might know exactly what the types of lamps or light bulbs used in every rooms, I know exactly the color of the wall surfaces (because I painted them), as well as the flooring and ceiling material, and many more. The ability to move the lights around, if needed, would also give me another advantage that is to see different alternatives or suggest a better solution to the lighting system. In addition to this, the solution offered at the end of this assignment would also benefit me in the future as I can apply the changes into the room and use them. In short, the selection of the room will give me more accurate data in greater detail to produce a high quality project. Yes, I understand the process might not be as complicated as the other colleagues that choose a museum, or some sort of more complex rooms, but I think the advantage of flexibility, accuracy, and detail it provides from selecting my own unit governs the overall consideration for the selection of a room. I hope these could result in a great and better project and analysis.

The Selection

General Data of the Room

Address: 33 Sheppard Avenue East, #2705

Unit type: 1 bedroom + 1 den

Rooms: 1 bedroom, 1 bathroom, 1 jacket and shoe closet, 1 laundry cabinet, 1 kitchen (with some fixed cooking and storage equipments), 1 living room, 1 den, and a balcony

Net Area: 48.853 m2

Orientation: orienting west (exposed to western sun) with a high-rise building (+\- 52 storeys) blocking the view partially

I have been living in this room for almost three years until the present time. Yet, of course, I do not spend all my time here, due to university, church, and other activities. But, the time I spend in this unit is considerable.

Average hours when I spend my time in my unit are as follows:

Monday: 12 hoursTuesday: 12 hoursWednesday: 13 hoursThursday: 15 hoursFriday: 9 hoursSaturday: 14 hoursSunday: 15 hours

Each room is used evenly. Nevertheless, because the den, living room, and the kitchen are connected to each other and the lighting in these rooms is the most crucial and complex, further study and analysis that is conducted in this assignment will be in regards to these rooms. From now further, the area to be studied will focus on the den, living room, and the kitchen.

Natural Light Exposure

Because the den, living room, and the kitchen are exposed to the western sun, the unit will feel really warm, or even worse, hot, especially in summer time. From my observation, the heat that comes to the unit from the direct sun will be at around 3:30 – 7:15 PM in spring/ fall season and at around 3:45 – 8:00 PM in summer season. The location of the unit in the 27th floor and the usage of the window wall system makes the sun light penetrates in until two-thirds (2/3) of the depth of the unit.

AdvantagesThe advantage of the unit orienting west is that I have much daylight to light up my unit (for living room, den, kitchen, and even bedroom). This reduces the need of artificial lighting during the day. At noon until sometimes in the evening, the daylight itself is enough. Another advantage of the unit orienting west is that it does not get really bright and hot in the morning (as it is not exposed to the eastern exposure) – it gives just enough lights into the unit without having excessive warmth in the rooms.

DisadvantagesYet, the western exposure results in a very hot unit in the summer time due to excessive sun light. Not just that, the glare is often being problematic too. The light gives too much glare on the west window wall that makes it hard for me to study or even use the table beside the window [furniture no. 5]. In times where people come to watch TV in the living room also become a problem due to excessive light and glare penetrating into the room. In response to this, however, the blinds [furniture no. 15] are often used in those times to shade the light that coming in to the unit. This results in the need of artificial lighting in the unit. In addition to this, the 52-storey apartment building in front of the unit also reflects light from its glass surface. Sometimes in the morning and late evening, it bounces the strong sun light from the east and north-west. It makes people inside the unit feeling dazzle and thus, feeling uncomfortable.

Figure 3. Room condition at evening, taken before 8 PM in April. The west sun lights the room just enough so little artificial lamps are needed. Yet, at this time, there are some dazzling light penetrating into the unit due to the strong western exposure and the reflection of light from the glass building in front. The wall on the left with Palm Breeze color (see figure 2) reflect the warm tone of the sun light.

Positive and Negative Aspects of Existing Lighting Environment

Most apartment units do not have many fixed lamps (mounted in the ceiling). In my unit, three out of the five rooms have mounted lamps, they are the den, living room, and the kitchen. Without the addition of the other lamps, the mounted lamps themselves will not be enough, especially at night time. Just the fixed lamps themselves, they can create some dark areas in the rooms, areas that are not covered by the beam spread of the lamps. So, additional standing lamps are required. The standing lamps though, give some advantages. Other than covering some uncovered areas by the ceiling-mounted lamps, their portability makes me easy to move them anywhere I need them to be. Also, their flexibility makes it easy to rearrange or reorganize the lighting placements following the reorganization of the furniture; i.e. the lighting can be easily adjusted to the change of room layout if needed. This is something that fixed lamps cannot do. When furnitures are moved, they only create other dark areas in other places. The in-adaptability of fixed lamps created the most problem in the den. The lamp was way too behind where the seat was so that it created shadows in the working table in the den while I was working. Sometimes the cast shadow was problematic because I could not see clearly to the papers or drawings I was working on. But, this was earlier solved, before this project commenced, by dragging the cap of the fixed lamp further in front so now it is align with the seating position and is not anymore casting shadows to the working table.

Figure 5. Another negative aspect of one of the luminaries: luminaire iv (refer to Figure 1 and 4). The lamp is so strong, making the dazzling effect while working. So, as a quick solution, a layer of yellow trace paper is used to cover the lamp. It reduces the dazzle but at the same time its translucent material provides some light to go through.

In general, there are no real problems found in the lighting environment (according to the simulation conducted. However, some aspects can be improved are:1. Kitchen preparation area is a little dark, 300 lux2. Kitchen storage cabinets are way too dark, only 100-200 lux3. Den does not have an even spread of light, more light at the back can be added4. Working/dining table (furniture no. 5) is way too dark, 200 lux5. A more even illumination in the living room area would be nicer

Simulation Analysis of Proposed Room Lighting Environment

Analysis:

Improvements in some areas including:1. Additional indirect light in the kitchen preparation area makes the kitchen brighter, 2. Re-lamping of three kitchen light bulbs to bulbs with higher lumen level (2 times bigger lumen level as the existing bulbs) 3. Additional wall-mounted indirect light beside the bedroom becomes an accent to the wall, makes the room more visually pleasing4. Additional Artemide Megaron Terra standing lamps on both sides of the living room TV rack make an even illumination across the living room area5. Repositioning of lamp v to the back of the den makes the den area evenly illuminated, being a more conducive area to work, especially works that are related to architecture (ex: detailed drawing) (1000 lux)

Improvement ResultHigher lumen level on the kitchen light bulbs and the accent lighting with track system in the living room area

Brighter area and evenly illuminated spaces, ex: kitchen preparation area, keyboard and seating area

Addition of indirect light in the kitchen preparation and storage area A safer place and more comfortable space to do food preparation or any other stuffs that related to the kitchen

Addition of wall-washing light beside the bedroom Creates an accent in the plain wall so the area seems visually more beautiful

Addition of table lamp Lighten up the working/dining table area at the corner (furniture number 5), so it is not anymore a dark area for working or eating

Addition of two Artemide Megaron Terra beside TV rack Creates uniform and even lighting in the living room, especially at areas that are near the TV

Higher lumen level on the pendant luminaire on the den Creates perfect lighting for detail works (1000 lux)

Repositioning of lamp number v to the back of den Creates uniform and more even lighting in the den area so it is a better environment condition for the eyes on long work times
