Assessing the error from failure to account for urban microclimate in computer simulation of building energy performance | 2009 | English
This paper provides a brief, non-exhaustive overview of the status of the application of CFD in building performance simulation for the outdoor environment. It focuses on four topics: (1) pedestrian wind environment around buildings; (2) wind-driv
A jet of cold air is denser then ambient air but it adheres to the ceiling of the room over the given distance when it is blown horizontally close to it.
Building simulation of thermal environment using response factor analysed by three-dimensional CFD | 2009 | English
Indoor climate has a three-dimensional spatial distribution caused by three-dimensional airflow. To obtain the accurate knowledge of building performance, it is demanded to integrate the spatial distribution into building simulations.

Computational Fluid Dynamics (CFD) has been introduced to the architectural engineering and HVAC (Heating Ventilation and Air Conditioning) industry for decades.
Results from a CFD reference study into the modelling of heat and smoke transport by different CFD-practitioners | 2009 | English
The paper describes results from a reference study that focuses on the application of the Computational Fluid Dynamics (CFD-) technique for heat and smoke transport in practice.
Sensitivity analysis of predicted convective heat transfer at internal building surfaces to diffuser modelling in CFD | 2009 | English
As a cost-effective alternative to experiments, computational fluid dynamics (CFD) can provide new insight in airflow patterns and the related convective heat transfer (CHT).
Combining different levels of detail in modelling for an improved precision of HVAC plant simulation | 2009 | English

A two-node heat and mass transfer network model for long-term simulation of void space of high-rise apartment houses equipped with gas-fired boilers | 2009 | English
A simplified model was developed by use of thermal-ventilation network with the purpose of studying air environment in void space at the central portion of high-rise apartment houses when gas-fired boilers were installed in the void.
The performance of hot water space heating systems for mild to warm temperate climates is dominated by the efficiency of boiler operation at low load (i.e. below 25% of nameplate capacity).
For the use in Swiss standards on energy performance of cooled buildings, a chiller model for an hourly time step calculation was needed.
