Evaluation of different thermal models in EnergyPlus for calculating moisture effects on building energy consumption in different climate conditions

Building energy simulation is essential for most architectural design projects. Many models have been developed to predict the indoor air temperature and relative humidity as well as the building’s heating and cooling loads. However, in most building energy analysis the calculation of heat conduction through walls usually neglects the transport and storage of moisture in porous building materials, and the interaction between hygrothermal transfer and airflow inside the building.

Validation of EnergyPlus thermal simulation of a double skin naturally and mechanically ventilated test cell

This paper presents a thermal simulation validation study of the typical precision that a trained thermal simulation engineer can expect to obtain for the simulation of a room connected to a naturally ventilated double skin facade. The open source building thermal simulation tool EnergyPlus is used to predict air and surface temperatures in a free running weather exposed test cell.

Comparison of measured and simulated performance of natural displacement ventilation systems for classrooms

Children spend the majority of their weekdays in classrooms that often have low indoor air quality and limited financial resources for the initial and running costs of mechanical ventilation systems. Designing effective natural ventilation (NV) systems in schools is difficult due to the intense use of the classroom spaces and the dependence of NV on building geometry and outdoor conditions. Building thermal and airflow simulation tools are fundamental to predict NV system performance in the design phase.

Modelling thermal comfort and energy consumption of a typical mixed-cooling apartment in Guilin, China

Many studies have shown that the use of mixed-mode cooling can bring down the cooling load significantly while maintaining satisfactory in door air quality and thermal comfort. But there is little information available concerning mixed-mode cooling in China. Thus, basing on design parameters of design standard, A series of computer simulation of a typical mixed-cooling apartment in Guilin, lies south-west of China, was conducted by Eneryplus and Climate Consultant software.
