Urban green space can improve the local thermal environment and thus quality of urban residential environment. Taking Beijing Olympic Forest Park (BOFP) as an example, this study analysed sample points representing different plant community structures, types, landscape environments based on 15 years continuous dynamic measurement selected typical annual data (from 2020). The explained spatial d...
Rumah merupakan salah satu tempat ternyaman yang ingin ditinggal oleh penggunanya, karena rumah peristirahatan setelah melakukan kegiatan di luar rumah. Maka penggunanya pasti menginginkan suasana dapat memberikan kenyamanan ‘termal’ ketika berada dalam bangunan. Untuk mengetahui menggunakan parameter suhu udara, kelembaban, kecepatan angin, radiasi insulasi pakaian, dan metabolic rate diperluk...
The thermal comfort of an enclosed room with air conditioner and air-distribution duct coupling can be studied, the parameters a split-fiber optimized on basis studying various parts human body. In this paper, model distributed was proposed. First, rationality three characterization models predict mean vote (PMV), predicted percentage dissatisfied (PPD), (PD) were verified through experiments s...
Background: The adoption of air conditioning (AC) is growing rapidly in developing countries across the world which puts a high burden on electricity distribution systems. This development is mostly driven by income growth and building design, but also due to increasing outdoor temperatures and to provide indoor thermal comfort. Current indoor thermal comfort standards are based on western clot...
The current paper propose the analysis and extension formulation required for establishing decision in the management of the medical national system from the point of view of quality and efficiency such as: conceiving models for the indices of thermal comfort, defining the predicted mean vote (on the thermal sensation scale) "PMV", defining the metabolism "M", heat transfer between the human bo...
This study characterizes the indoor airflow and occupants’ thermal sensations in a cross-ventilated building model sheltered by generic cube arrays based on large-eddy simulations (LESs). Four ventilation models, which comprise different cross-ventilating openings, streamwise (STR) lateral (LAT) windows, block arrangements, lattice-type square (SQ) staggered (ST) patterns, were examined to unde...
Abstract Thermal conditions in buildings are influenced by climatic and determined the thermal performance of building itself. The condition is caused transfer heat flow between environment building. This study aims to analyze value temperature, humidity, solar radiation, wind speed with presence water element as a modifier microclimate well comfort for adaptation visitor behavior. research foc...
بررسی عددی تأثیر سرعت و مکان قرارگیری فنسقفی بر آسایشحرارتی و کاهش مصرف انرژی در ساختمانهای اداری
هدف از مطالعه حاضر بررسی عددی تأثیر سرعت و مکان قرارگیری فن سقفی بر پارامترهای آسایش حرارتی و مصرف انرژی در دو نمونه اتاق اداری متفاوت با ابعاد مشخص در فصل زمستان با سیستم گرمایش متمرکز است. در تمامی مدلها رژیم جریان آشفته بوده و از مدل k-ε برای مدلسازی آشفتگی استفاده شده است. بر اساس نتایج، استفاده از فن سقفی، بدون درنظرگرفتن مکان آن در یک ارتفاع مشخص، باعث کاهش مصرف انرژی میشود. با روشن کر...
