In recent years, there have been numerous studies on the application of retroreflective (RR) materials to exterior building walls relieve urban heat island (UHI) phenomenon and save energy consumption instead diffuse highly reflective (DHR) materials. Experimental measurements were undertaken investigate impact applying DHR RR outdoor thermal environment. tested with three canyon aspect ratios ( H / D ) 0.5, 1.0, 1.5, respectively, seven environmental indexes recorded compared, including air...

The heat rejected by outdoor units of split A/C conditioners can impact the ambient environment mixed-mode buildings. Nevertheless, how this environmental may affect space-conditioning energy use and indoor air pollution is poorly understood. By coupling EnergyPlus Fluent, study examines effects units’ rejection on building surroundings, cooling load, PM2.5 exposure a six-storey building. had an open-plan room each floor, with unit positioned below window. coupled model was run for selected...

The heating, ventilation, and air conditioning (HVAC) system is a major energy consumer in office buildings, its operation critical for indoor thermal comfort. While previous studies have indicated that reinforcement learning control can improve HVAC efficiency, they did not provide enough information about end-to-end (i.e., from raw observations to ready-to-implement signals) centralized systems multizone buildings due the limitations of methods or test being single zones with independent...

Computational fluid dynamics (CFD) technique is well-known for its powerful capability of modelling the cross-ventilation. CFD broadly coupled with energy simulation programmes, such as EnergyPlus, to expand application in building calculation. During coupling process, iterative calculation required improve accuracy method, which means scale model should be designed extra care so that can practical terms computational cost. A coarse-resolution mesh (here denoted c ) cannot properly represent...

The current market of the photovoltaic (PV) industry is dominated by silicon-based modules, which are malfunctioned and degraded in higher temperatures mainly above 25 °C. Consequently, one challenges for such modules finding a more efficient way their integration into buildings order to reduce mentioned temperature. present work part comprehensive framework toward investigation lifetime durability BIPV modules. Therefore, this paper explain development validation computational fluid...

Exterior shading devices and outdoor units can be closely coupled since these two building components are commonly installed next to each other. This study uses a EnergyPlus-Fluent modeling approach examine how combination of exterior heat rejection from affect the ambient environment building, changes in influence cooling loads indoor PM2.5 exposure. Three were simulated, including horizontal overhangs, vertical fins. Data wind-tunnel experiments field measurements used ensure accuracy...

Understanding of cell temperature Building Integrated Photovoltaics (BIPV) is essential in the calculation their conversion efficiency, durability and installation costs. Current PV models mainly fail to provide accurate predictions complex arrangement BIPVs under various climatic conditions. To address this limitation, paper proposes a new regression model for prediction BIPV climates design conditions, including effects relative position roof edge, solar radiation intensity, wind speed,...
