“…In the autumn, the neutral temperature was estimated to be between 22.4 and 29.2°C but it was not calculated in the summer. In general, the studies summarized in Table suggest that the optimal temperature for tropically acclimatized pupils is a few degrees higher than it is for pupils in moderate climates …”

“…In general, the studies summarized in Table 1 suggest that the optimal temperature for tropically acclimatized pupils is a few degrees higher than it is for pupils in moderate climates. [7][8][9] Thermal discomfort can have both long-term and short-term consequences for the learning process that affect not only school work but also the entry into working life. This has been clearly shown in 18 studies to date that examined the effects of thermal conditions on the performance of schoolwork by elementary and secondary school pupils.…”

A two-week-long intervention study was performed in two classrooms in an elementary school in Costa Rica. Split-cooling air-conditioning (AC) units were installed in both classrooms. During the first week, the air temperature was reduced in one classroom while in the other (placebo) classroom the fans were operated but no cooling was provided. During the second week, the conditions were exchanged to create a 2 × 2 crossover design in which each pupil was their own control. A total of 37 children performed tasks similar to school work and completed questionnaires reporting their thermal sensation and perceptions. Operating the AC units reduced classroom temperature by about 5 K, from about 30 to 25°C. Thermal sensations changed from hot to neutral and slightly cold, and the percentage of children rating the thermal conditions as acceptable increased significantly. Neutral temperature was estimated to be about 27°C. The 11-year-old children performed the language and logical-thinking tasks significantly better in terms of speed at the lower temperature, while the less able pupils performed better on all tasks at the lower temperature. There were no significant effects on accuracy. These results confirm published findings from moderate climates and extend their validity to the tropics. They indicate that acclimatization can increase the optimal temperature for learning.

“…Suhu global diperkirakan meningkat dari 0,7 menjadi 3,92 °C pada akhir abad ini. Kesehatan manusia di Indonesia secara langsung dipengaruhi oleh kenaikan suhu (IPCC 2007), yang dapat memperburuk keadaan ini salah satunya adalah kondisi kenyamanan indoor atau Indoor Environmental Quality (IEQ) di dalam bangunan (Montazami, 2017). Bersamaan dengan naiknya suhu di luar dan di dalam bangunan, perilaku penghuni memiliki dampak yang signifikan dalam pengembangan dan juga mengendalikan risiko overheating (Sameni, 2015).…”

Sektor konstruksi dan bangunan, terutama hunian dan bangunan komersil, berkontribusi hampir 40% dalam mempercepat proses pemanasan global. Hal ini disebabkan oleh konsumsi energi berlebih oleh penghuni bangunan dalam upaya beradaptasi dengan perubahan suhu pada tempat tinggalnya. Walaupun demikian, hal ini dapat diantisipasi oleh stakeholder terutama arsitek dan desainer dengan menerapkan model desain yang berorientasi pada perfoma bangunan pada saat tahap awal desain. Perancangan arsitektur masa kini banyak mengalami perubahan dikarenakan pengaruh dari perkembangan komputer. Digital design salah satu cabang yang berkembang dalam arsitektur memiliki peran yang sangat penting dalam membentuk pola pikir desain arsitektur masa kini. Sebut saja Parametric Design dan Generative Algorithm, yang merupakan suatu pendekatan desain yang mengandalkan kemampuan komputer dalam mengambil alih perhitungan-perhitungan matematis yang komplek dalam proses perancangan arsitektur. Penelitian ini akan membahas penggunaan platform tersebut dalam menginvestigasi peran dan fitur dari komponen fasad diantaranya panjang kanopi jendela, luas permukaan bukaan, tinggi ambang atas dan bawah dari jendela dan derajat perputaran orientasi bangunan dengan studi kasus Institut Teknologi Sumatera, dengan iterasi secara generative untuk mengukur target goal dari proses perancangan seperti Operative Temperature, View Percentage, Daylight Simulation, Surface Temperature, Sun Hours Simulation. Hasil yang didapatkan dari proses iterasi pada 34 generasi menggambarkan preferred solution adalah individual yang memiliki sudut perputaran 6 derajat, Panjang cantilever jendela 0.9 meter, glazing ratio 0.2%, tinggi ambang atas dan bawah jendela adalah 3,5-meter dan 10 cm.

“…Different authors [7]- [17] have sought with their research to mediate the influence of both connotations, where, the basis of thermal perception focuses on the physical and psychological sensations generated by the stimuli of the thermal environment, the activity in development, the experience and the expectation of the people. Nikolopoulou [8] defines thermal comfort as "(...) psychophysiological satisfaction of the human being regarding thermal environment", where the psychological and physiological aspects of the human being intervene to perceive the thermal environment and offer a subjective vote from thermal sensation, preference, expectation, and tolerance [18]; while the ANSI/ASHRAE 55 [9] understands it as "(...) the condition of the mind (...), determined by subjective evaluations (...), which expresses satisfaction with the thermal environment".…”
