ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh kenyamanan termal para siswa dalam ruang kelas serta untuk mengetahui seberapa besar pengaruh bukaan terhadap kenyamanan termal siswa di ruang kelas. Objek dari penlitian ini adalah tiga ruang kelas di SDN Pondok Jagung 1, Kota Tangerang Selatan.  Kelas yang diteliti adalah dua kelas di lantai satu dan satu kelas di lantai dua. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dan kuantitatif yang digunakan sebagai metode pengumpulan data. Yaitu berupa kuesioner (Kualitatif) dan pengukuran kenyamanan termal menggunakan alat pengukuran (kuantitatif) berupa kecepatan angin (Anemometer Vane Probe), pengukuran suhu permukaan (Infrared Thermometer) dan pengukuran kelembapan ruangan. (Dry and Wet). Pengukuran yang dilakukan mengggunakan tiga experiemen yaitu dengan ventilasi tertutup semua, ventilasi terbuka menyilang dan ventilasi terbuka semua. Dari hasil tersebut maka dapat disimpulkan bahwa semakin banyak ventilasi yang terbuka maka semakin rendah nilai PMV yang diperoleh karena suhu udara akan semakin dinging. Kemudian semakin banyak ventilasi yang dibuka maka nilai PPD (%) akan semakin menurun. Sehingga benyaknya ventilasi pada ruangan akan mempengaruhi kenyamanan termal ruangan. Sedangkan nilai kenyamanan termal yang diperoleh adalah kelas 3A dan 3B belum memnuhi kenyamanan termal. Namun kelas 4A adalah kelas yang paling mendekati zona Kenyamanan termal. Kata Kunci : Kenyamanan Termal, PMV, Ruang Kelas.  ABSTRACTThis study aims to determine the effect of thermal comfort of students in the classroom and to find out how much influence the openings to the thermal comfort of students in the classroom. The object of this research is three classrooms in SDN Pondok Jagung 1, Kota Tangerang Selatan. The researches are two classes on the first floor and one class on the second floor. The method used in this research is qualitative and quantitative method used as data collection method. Namely the questionnaire (Qualitative) and thermal comfort measurements using measurement tools (quantitative) in the form of wind speed (Anemometer Vane Probe), measurement of surface temperature (Infrared Thermometer) and humidity measurement of the room. (Dry and Wet). Measurements were made using three experi- ences: all closed ventilation, open cross ventilation and all open ventilation. From these results it can be concluded that the more open ventilation, the lower the PMV values is obtained because the air temperature will be more dinging. Then the more ventilation opened then the value of PPD (%) will decrease further. So that the ventilation in the room will affect the thermal comfort of the room. While the thermal comfort value obtained is class 3A and 3B have not fulfilled thermal comfort. However class 4A is the class closest to the Thermal comfort zone.

Different Dimensions

Considering the large number of participants and the heterogeneity of the group, the research methodology of COBEREN has been defined in a very specific way. The authors implemented a mixed methodological approach, combining qualitative and quantitative techniques, and they used a various range of numerical, verbal, and even pictorial measurements. The scope for covering different dimensions of the consumer culture was made as open as possible but had to remain acceptable from the point of view of the survey response process. Finally, they successfully combined some a priori instructions/guidelines and some a posteriori adjustments/adaptations. This chapter introduces the data collection method, the sampling aspects, the questionnaire design and translation, implemented according to the general principles of the COBEREN methodology.

The Impact

Significant changes in the urban built environment have occurred due to rapid urbanization and increases in the urban population. Such alterations may produce environmental health-related issues such as urban heat stress, air pollution and traffic noise. This research undertook a field study to collect data including urban design parameters, micro-environmental factors and city climatic information. This work was conducted over a two-year period on three pedestrian streets located in high-density urban areas in Beijing. These areas were selected in order to study the influences of urban street canyon texture within a particular geometric layout, wind flow corridors and variations in air temperature on pedestrian microclimatic comfort. The results will facilitate the work of urban planners by providing them with information for use in improving outdoor thermal comfort through their designs. A total of 60[Formula: see text]485 samples were organized into training, validation and test sets. We confirmed our hypothesis that internal wind speed ([Formula: see text] is attributable mainly to the urban texture coefficient ([Formula: see text], air temperature ([Formula: see text] and leading-in wind speed ([Formula: see text]. The model was tested using the test data collected onsite, which demonstrated a very accurate goodness-of-fit; the model achieved an R-squared value of 0.82, which meant that [Formula: see text] as a dependent variable was 82% correlated to the three predictors as independent variables. With this computer simulation, urban planners can now predict and visualize the impact of changes on the built environment in terms of either the direction of solar radiation received or increases in wind speed, in return for the desired thermal comfort level for residents of the neighborhood.

ABSTRAK Mall saat ini marak menggunakan clerestory sebagai salah satu upaya untuk penerangan alami pada siang hari. Namun, cahaya matahari pada sore hari (barat) akan menghasilkan cahaya matahari yang lebih panas dan silau dibandingkan cahaya matahari pada pagi hari (timur). Oleh karena itu, dengan pemakaian clerestory yang cukup besar pada bangunan, masalah panas tentu tak dapat dihindari. Begitu pula dengan glare yang berasal dari pantulan sinar matahari. Salah satu Mall yang menggunakan clerestory adalah Mall AEON BSD. Pengukuran suhu udara, temperatur efektif, kelembaban udara, kecepatan angin, PMV (Predicted Mean Vote) dan PPD (Predicted Percentage of Dissatisfied) dilaksanakan pada 4 waktu dengan 5 lokasi titik ukur yang memiliki kondisi berbeda untuk membuktikan bahwa clerestory dapat mempengaruhi kenyamanan termal. Disimpulkan bahwa titik 2 yaitu titik yang berdekatan dengan clerestory sisi kanan (ukurannya lebih kecil daripada clerestory sisi kiri) memiliki temperatur efektif dan kelembaban udara yang lebih rendah dari titik lain, dan kecepatan udara (dipengaruhi oleh hembusan AC) lebih tinggi dari titik lain. Responden merasa nyaman saat berada di titik tersebut.Titik paling nyaman menurut responden adalah titik 2 dengan TE rata-rata berkisar 27,4˚C, kelembaban udara rata-rata berkisar 52,2%, kecepatan udara rata-rata berkisar 0,15 m/s, PMV berkisar 0,5 dan PPD berkisar 12,7%. Dengan begitu semakin kecil ukuran skylight terbukti mempengaruhi kenyamanan termal dan membuat kenyamanan termal dapat tercapai. Kata Kunci: Mall, Clerestory, PMV, PPD, Kenyamanan Termal ABSTRACT Nowadays mall is decorated with clerestory as an effort to lighten naturally during the day. However, sunlight in the afternoon (west) will produce more sunlight and glare than sunlight in the morning (east). Therefore, with the use of a fairly large clerestory in buildings, the problem of heat certainly can not be avoided. Similarly, glare that comes from the reflection of sunlight. One of the malls that use clerestory is BSD AEON Mall. Measurement of air temperature, effective temperature, air humidity, wind speed, PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) carried out at 4 times within 5 measuring spots that have different conditions, proving that clerestory can affect thermal comfort. It was concluded that point 2, which is the point adjacent to the right side clerestory (smaller in size than the left side clerestory) has an effective temperature and lower air humidity than other points, and air velocity (affected by blowing AC) is higher than other points. Respondents felt comfortable when they were at that point. The most comfortable point according to respondents was point 2 with TE averaging around 27.4˚C, air humidity averaged 52.2%, the average air speed ranged from 0.15 m / s, PMV ranges from 0.5 and PPD ranges from 12.7%. Thus, the smaller size of the clerestory is affecting thermal comfort and thermal comfort can be achieved. Keywords: Mall, Clerestory, PMV, PPD, Thermal Comfort

Tourism Potential

To describe the tourism potential of an area, not only single meteorological parameters have to be taken into account, but also thermal sensation and people’s thermal comfort. The latter can be estimated by the use of human energy balance models and the derived thermal indices, which comprise all relevant meteorological parameters like air temperature, air humidity, wind speed, and short and long wave radiation fluxes. This paper makes an attempt to assess and analyze climatological parameters and the thermal comfort of Crete, its variations and trends for the period of time 1955-2001. In addition, a definition and quantification of the island’s tourism potential is carried out. Long term data from several stations are used from the existing climatic and synoptic network of Crete, including daily mean, maximum and minimum temperature, relative humidity, wind speed, and cloud cover over the whole island, in order to derive the daily Physiologically Equivalent Temperature (PET) and precipitation. In addition, possible trends of thermal comfort and precipitation on an annual and seasonal basis are analyzed. Additionally, data of the 10-minutes climatology of the Climate Research Unit of the University of Norwich have been processed in order to create high resolution (1 km) mean monthly maps for climatological parameters such as air temperature, precipitation and Physiologically Equivalent Temperature.
