The reference building models in the EnergyPlus tool do not consider stack effect. This is an issue for small and low-rise buildings. However, this significant evaluating heating cooling load of high-rise study evaluates quantifies effect energy simulation, EnergyPlus. commercial model set was used as a simulation test bed. vertical multi-stories shaft zones were added inside core zone existing...

In this paper, the thermal performance of four common insulators in two internal and external insulation systems is investigated for the ASHRAE setpoint range by applying detailed numerical simulation and Anti-Insulation phenomenon. Anti-Insulation phenomenon and consequent extra load on the HVAC system can occur following the thermal insulation of a building if proper temperature setpoint is n...

Several studies have analyzed the integration of energy-saving strategies in buildings to mitigate their environmental impact. These focused mainly on a disaggregated analysis such and effects building's energy consumption thermal behavior, using engine simulation software (EnergyPlus, TRNSYS, DOE2) or graphical interface (DesignBuilder, eQuest, ESP-r). However, are complex systems whose behavi...

Simplification of building energy models is one the most common approaches for efficiently estimating performance buildings over a whole city. In city-scale models, abstraction into an information model and division representative thermal zones cannot be building-specific but must generic applicable to many buildings. Considering limited research on such methods, in this study, comprehensive ev...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the ...

In the quest for a better use of energy resources, integration, and cogeneration strategies have been employed in industrial commercial sectors with considerable benefits realized. However, residential sector remains underexplored. An optimization procedure should be carried out whenever there is need to ensure or verify economic viability an system. This study uses Mixed Integer Linear Program...

Global warming is expected to raise the average temperature of tropical region by up 3–4°C in next 70 years. Due vulnerable living conditions that are predominant most developing countries region, this will dramatically affect indoor thermal performance exclusively, naturally ventilated buildings form majority residential less-industrialized nations. In addition, lack knowledge about built envi...

Temperature control in buildings has been a highly studied area of research and interest since it affects the comfort occupants. Commonly, temperature systems like centralized air conditioning or heating work with fixed set point locally at thermostat, but users turn on off system when they feel is too hot cold. This configuration clearly not optimal terms energy consumption even thermal for us...
