Illumination & Acoustics Evaluation Of Indoor Light Quality Provided to: Dr. Abdulsalam Alshboul Hajer Almrayat 2210177 Rahaf Sous 0215927 Walaa Barakat 0228926 Location : Arts & Design facility ,Architecture studio (indoor space). ( second floor – room 202) Weather : Sunny clear day (temperature ranging between 31-34) Time : 9:00PM , 12:00 PM , 3:00 PM 1. The device used: The lexometer and its alternative is a phone application It is used to study the intensity of lighting in each room and any surface in it and the reflection of light as well to help determine if the lighting is suitable for the room according to the classification of the room studied and the intensity of lighting suitable for it. How the program works: The phone is directed to the surface on which you want to know the illumination or the reflected light. After that, the value appears and is evaluated to see if it is good or not, and solutions are given to improve the lighting in the hall. APP USED: LUX O METER 2. FUNCTION & LIGHTING STANDARDS: Task Lighting: For detailed drawing work, it's recommended to have a minimum of 750 lx at the work surface. General studio lighting: In addition to task lighting, it's important to have general lighting to provide overall illumination to the studio space. This can be around 300-750 Ix. This helps to create a well- lit environment that reduces shadow and provides a comfortable working atmosphere. 3. OPENINGS & PHYSICAL ENVIRONMENT CHARACTERISTICS: 1. Architectural Studio having an area of 75.6 m2 , and a (60*60 cm) grid false ceiling. 2. The classroom containing two (1.5*1.2 m) openings (double glazed) along the southeast side. The reason for choosing this classroom: the room area is relatively large and contains only two windows. The natural lighting does not enter the classroom very well and it is relatively dark. Even the artificial lighting is considered small in relation to the area of the room and its need for light, as some areas are dark and others are illuminated. 4. PLAN AND SECTION: 5.LIGHTING PLAN: Lighting: There are (12 )lighting panels, each containing 4 Philips (Fluorescent) Light bulbs. The lighting capacity of each bulb is (18). 4. MEASURING LIGHT QUALITY BY LUX-LIGHT METER DEVICE. After obtaining the needed data using the lux light meter to measure the illuminance reaching a surface in an architectural studio, the following data were obtained (table 1,2 and 3) measuring the illuminance every.90 m, moving in rows from the entrance towards the studio window. The experiment was repeated twice, once by leaving the lighting on and then turning it off. And at two different time periods (9:00 am & 12:00 pm &3:00pm). -GRID LAYOUT SPOT: ENTRANCE  Table (1) :24th July 2024 – 9:00 am -Light off Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 34 27 27 32 38 33 R.2 1.8 32 31 32 38 35 37 R.3 2.7 37 39 38 37 38 39 R.4 3.6 41 45 39 37 40 40 R.5 4.5 49 48 47 45 49 49 R.6 5.4 50 49 51 50 48 47 R.7 6.3 60 56 57 59 54 57 R.8 7.2 67 68 72 77 71 75 R.9 8.1 100 94 103 108 103 100 R.10 9 102 110 108 116 120 121 R.11 9.9 130 135 136 139 140 134 R.12 10.8 194 234 183 225 304 301 standard 750 750 750 750 750 750 Table (1) :24th July 2024 – 9:00 am -Light on Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 160 228 269 221 265 165 R.2 1.8 172 216 338 270 226 176 R.3 2.7 206 383 404 380 340 244 R.4 3.6 317 407 400 343 415 253 R.5 4.5 313 343 396 330 323 260 R.6 5.4 280 440 500 413 428 280 R.7 6.3 330 420 510 430 445 285 R.8 7.2 353 417 443 428 426 285 R.9 8.1 415 547 528 508 512 340 R.10 9 424 534 634 540 625 435 R.11 9.9 414 515 643 547 640 428 R.12 10.8 531 625 394 475 776 782 standard 750 750 750 750 750 750  Table (2) :24th July 2024 – 12:00 pm -Light off Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 32 33 32 33 35 33 R.2 1.8 31 32 32 33 34 36 R.3 2.7 32 34 36 37 37 39 R.4 3.6 40 42 43 42 45 45 R.5 4.5 46 45 46 49 48 50 R.6 5.4 92 87 89 90 92 91 R.7 6.3 133 138 142 145 148 170 R.8 7.2 143 169 178 177 182 187 R.9 8.1 240 276 289 290 308 285 R.10 9 297 300 300 306 323 362 R.11 9.9 458 525 567 588 751 610 R.12 10.8 693 830 680 713 871 820 standard 750 750 750 750 750 750 Table (2) :24th July 2024 – 12:00 pm -Light on Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 154 313 251 249 310 160 R.2 1.8 150 310 212 330 320 203 R.3 2.7 320 470 510 495 490 395 R.4 3.6 410 490 585 494 473 415 R.5 4.5 405 505 575 502 481 420 R.6 5.4 430 554 605 575 554 467 R.7 6.3 480 570 706 670 610 498 R.8 7.2 500 600 740 689 612 501 R.9 8.1 580 725 850 722 738 705 R.10 9 675 842 865 790 837 730 R.11 9.9 876 863 855 923 930 885 R.12 10.8 876 882 880 879 980 952 standard 750 750 750 750 750 750  Table (2) :24th July 2024 – 3:00 pm -Light off Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 28 29 32 35 36 38 R.2 1.8 30 33 33 34 36 38 R.3 2.7 33 33 34 36 35 36 R.4 3.6 34 34 42 43 43 46 R.5 4.5 42 44 44 46 50 60 R.6 5.4 92 85 90 87 92 91 R.7 6.3 123 135 145 147 163 168 R.8 7.2 133 154 167 174 188 192 R.9 8.1 220 289 289 290 308 285 R.10 9 285 310 290 310 322 398 R.11 9.9 430 443 520 632 743 620 R.12 10.8 556 793 696 725 820 833 standard 750 750 750 750 750 750 Table (2) :24th July 2024 – 3:00 pm -Light on Row DISTANCE(m).90 1.8 2.7 3.6 4.5 5.4 No. R.1.90 132 300 268 275 314 183 R.2 1.8 140 320 238 380 326 213 R.3 2.7 318 489 522 498 520 235 R.4 3.6 403 501 620 500 482 434 R.5 4.5 389 525 613 510 482 457 R.6 5.4 420 542 629 567 512 479 R.7 6.3 476 568 716 689 620 514 R.8 7.2 505 554 635 692 626 529 R.9 8.1 500 689 790 735 748 745 R.10 9 625 839 873 730 853 768 R.11 9.9 856 858 880 805 913 873 R.12 10.8 862 889 885 873 974 972 standard 750 750 750 750 750 750  9:00 AM -

Additionally, because the design studio is located in the south-eastern the area where the daylight is bright just in where there is opening (windows), as it varies depending on the season and sometimes there's good light near to the drawing tables near the windows, however the artificial lights set up to make up for the lack of daylight to reach the rest of the room are not placed correctly As how in the following pic, we could see that at this area the natural light is reaching more than the rest of the room 7-SOLUTION Therefore, to improve the lighting in the studio, we could switch to more efficient LED lights and implement a lighting strategy that includes background, task, and feature lighting. We can make sure that every area is well-lit, adjust the color and brightness, and reduce glare with fixtures that can dim. We could install lighting controls such as motion sensors and timers to save energy and keep the fixtures in good condition. By thoughtfully adjusting the placement of the lights, this strategy will create a welcoming, visually pleasing space that supports creativity and productivity in the design studio.
