This study examines the impact of future climate change on energy consumption in residential buildings Japan, taking into account both current and typical meteorological year (TMY) database. TMY data is widely used building sector for performance assessments, system sizing, optimization. To investigate databases buildings, predicts cooling heating loads four cities Japan under (2020 ver.) (2086 databases. Results show that use database leads to significant changes air-conditioning heat...
In recent years, the uncertainty of weather conditions and impact future climate change on building energy assessment has received increasing attention. As an important part these studies, several types methods for generating stochastic meteorological data have also been developed. Since solar radiation drops to zero at night, unlike continuous 24-hour elements such as temperature humidity, this posed challenges previous research fully account simultaneity among multiple elements. Therefore,...
In Japan, in order to determine the capacity of air-conditioning equipment, designers usually use weather database Reference Weather Year (RWY) obtain design load by using software such as New HASP/ACLD and Building Energy Simulation Tool (BEST) that are often used Japan. recent years, with global warming due climate change, calculate air conditioning also changes. Thus, an appropriate equipment for energy conservation buildings, deviation calculated RWY Actual (AWY) should be discussed....
In the common method of compiling outdoor design conditions by annual cumulative frequency occurrence, probability simultaneous occurrence selected meteorological elements is not considered, which may lead to an overestimation air-conditioning equipment capacity design. This paper aims at developing a novel approach for producing conditions, taking into consideration dependency between air temperature and global solar radiation, have strong influence on HVAC These two are analyzed specific...
This in-depth study explores the intricate dynamics of reflective materials, emphasizing their impact on indoor thermal environment and urban heat island (UHI) mitigation. Examining diffuse highly (DHR), general (GR), retro-reflective (RR) materials a simplified building model during summer days, research utilizes outdoor experiments to analyze air surface temperatures, as well solar radiation. Prioritizing key metrics—mean radiant temperature (MRT), operative (OT), reflectance (ρ)—the...
In HVAC system design, the commonly used method recommended by ASHRAE has not sufficiently analyzed correlation between meteorological elements when generating outdoor design conditions for purposes. If most important to determine appropriate air conditioning capacity, temperature, absolute humidity and solar radiation are selected annual cumulative frequency of occurrence independently, it may cause an overestimation in selecting air-conditioning capacity. Therefore, as extension...
