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.
Use of whole building simulation in on-line performance assessment: modeling and implementation issues | 2001 | English
The application of model-based performance assessment at the whole building level is explored.
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.
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.
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.
Use of 'Comfie' computer simulation tool for evaluation of thermal performance in housing units | 2001 | English
This work deals with the use of the thermal simulation COMFIE tool, in the research project developed at Londrina State University / PR.
In low energy dwellings the ventilation heat losses are significant. Reducing this heat losses can be done by introducing demand controlled ventilation i.e.
This paper describes novel high-performance visualization techniques for reviewing time dependent data common to building simulation.
Synchronous calculation of transient hygrothermal conditions of indoor spaces and building envelopes | 2001 | English
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.
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,
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
When modernist architecture in the tropics started in the 30´of the 20th century, air-conditioning systems and special glazing were not yet available.
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
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
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.
