The size of the window-to-wall ratio is a key factor affecting natural lighting, ventilation and energy consumption building. Taking Yanqui Library Jimei University as object combined with different shading conditions, range window-wall ratios that simultaneously meet requirements lighting saving derived by using Revit, Ecotect PKPM software simulations around ventilation. main conclusions are ...

Abstrak_ Pada umumnya, bangunan gedung mengonsumsi sekitar sepertiga dari total konsumsi energi dunia. Sebagian besar pada di Indonesia digunakan oleh sistem pengkondisian udara. Salah satu upaya yang dapat dilakukan untuk meminimalisir pemborosan penghawaan udara adalah dengan menurunkan OTTV (Overall Thermal Transfer Value) mengurangi panas eksternal masuk melalui selubung bangunan. Penelitia...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...

School buildings as a major part of public buildings are considered as one of the basic consumers of energy in Iran. Based on building typology and occupancy patterns, school buildings have a great potentiality for energy optimization while providing thermal comfort. This study investigates the architectural design parameters such as orientation, optimum window to wall ratio, space organization...
