This paper refers to the existence of the variety modes and 'Chaos' in building natural ventilation or smoke venting, systems, and provides the some computational instances by means of the network model.
Simulation of the wind in hot and humid climates cities: evaluation of the natural ventilation potencial of the housing in urban blocks | 2001 | English
This work is a multidisciplinary approach of natural ventilation in hot and humid climates. Our aim is the control of thermal comfort in tropical towns. We evaluate the natural ventilation potential of different shapes of the dense housing.
Thermal performance simulation and the urban microclimate: measurements and prediction | 2001 | English
Computer models used to predict building heating and cooling energy and occupant thermal comfort at present rely on climate data collected at a remote meteorological station.
The adaptive couling of computacional fluid dynamics with whole-building thermal simulation | 2001 | English
A adaptive controller was devised and implemented within the ESP-r simulation program to support the conflation of CFD with dynamic whole-building thermal simulation.
This paper provides an overview of how building simulation is used to support a Canadian Govern- ment energy-efficient incentive programme.
In low energy dwellings the ventilation heat losses are significant. Reducing this heat losses can be done by introducing demand controlled ventilation i.e.
The use of multiple building performance simulation tools during the design process: a case study in Singapore | 2001 | English
This paper discusses the use of multiple building performance simulation tools to support the design of a state-of-the-art intelligent library building in Singapore.
Synchronous calculation of transient hygrothermal conditions of indoor spaces and building envelopes | 2001 | English
Use of energy performance simulation for operation cost distribution in multipurpose conventional centre | 2001 | English
The paper describes case study of application of computer simulation in the field of operational energy costs distribution in the building with variable operation and no possibility of direct energy consumption measuring.
Building Integrated Photovoltaic (BIPV) system implementation is on the rise worldwide. A computer modeling tool was developed to predict BIPV system power generation in commercial buildings.
Regression analysis of electric energy consumption and architectural variables of conditioned commercial buildings in 14 Braziliam cities | 2001 | English
The aim of this work was to develop a simple model to predict the electric energy consumption of office buildings artificially air-conditioned, for 14 (fourteen) Brazilian cities (Belém, Brasília, Curitiba, Florianópolis, Fortaleza, Maceió, Natal
Impact of a veranda on the reduction of the energy consumption in residential buildings: an application of the Clim2000 software | 2001 | English
In this paper, the impact of a veranda (attached sunspace) on energy consumption is analyzed by numerical simulations (Clim2000 software) for two different configurations : a (existing) residential individual house and a (new) apartment bu
We give an overview of how windows are modeled in the EnergyPlus whole-building energy simulation program. Important features include layer-by-layer input of custom glazing, ability to accept spectral or spectral-averaged glass optical properties,
Numerical modeling of the influence of angle adjustment of A/C diffuser vanes on thermal comfort in a computer room | 2001 | English
In the paper, based on MS Thesis by Richtr, 2000, the authors describe CFD modeling of a computer room with regard to thermal comfort of workers.
Energy savings from the use of daylighting in commercial buildings are realized through implementation of photoelectric lighting controls that dim electric lights when sufficient daylight is available to provide adequate workplane illumina
When modernist architecture in the tropics started in the 30´of the 20th century, air-conditioning systems and special glazing were not yet available.
Potential for heat stress relief using desiccant systems in swinw breeding facilities | 2001 | English
Heat stress associated with extreme temperatures and relative humidity has been shown to reduce the productivity from swine facilities, especially breeding facilities.
The HVAC BESTEST has been developed within the framework of the IEA (International Energy Agency) It is a comparative test method developed for estimating the ability of whole building simulation programs to model the performance of unitary space
