This paper describes novel high-performance visualization techniques for reviewing time dependent data common to building simulation. These techniques enable rapid inspection of trends and singularities, in the data that are difficult to ascertain  from conventional methods. In the case of daylight simulation, understanding when and where daylight is available in a proposed design can lead to significant energy savings in the resulting electric lighting systems of buildings. These new visualization techniques are introduced through three case studies.

This paper deals with the development and the testing of a simulation algorithm for the temperature behaviour and the flow characteristics of double façades. It has been developed in order to obtain a tool which enables the energy consultant to make quick design decisions without being required to use fairly complicated CFD tools. In order to determine the degree of accuracy of the algorithm, a double façade has been monitored under controlled conditions and the results have been compared against the predicted values for several design situations.

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.

Despite  discussions  of  the  universal  workstation, there is increasing workplace dynamics in organizations. These dynamics include space configuration changes, changes in occupant density, and increasing equipment density. Building infrastructures have not evolved to meet these demands, with little flexibility in air conditioning and ventilation, lighting, electrical, and telecommunication systems in new or existing office buildings. Simulation tools can be used to evaluate dynamic workplace scenarios and provide guidance for designers by modeling indoor environmental conditions.

This paper provides an overview of how building simulation is used to support a Canadian Govern- ment energy-efficient incentive programme. It describes the two software tools (detailed simulation software and a simplified web-based method) that were developed to support the programme. The classroom and computer-based initiatives used to train users are also described, this being key to support programmes of this nature.

The    application    of    model-based    performance assessment at the whole building level is explored. The information requirements for a simulation to predict the actual performance of a particular real building, as opposed to estimating the impact of design options, are addressed with particular attention to common sources of input error and important deficiencies in most simulation  models. The role of calibrated simulations is discussed.

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. The simulation is used to predict energy needs related to the climatic loads and to make a synergy with the internal loads. Presented results are in terms of average energy consumption related to floor area and operational case, divided into the heating, cooling and electric energy .

This work deals with the use of the thermal simulation COMFIE tool, in the research project developed at Londrina State University / PR. In this research, 3 different building systems, represented by inhabited houses, are thermal-simulated and monitored. The obtained results are compared. The results allow us to verify the applicability and improve evaluation methods of thermal behavior of low-cost housing. 

Two  prototype  office  buildings  with  low  internal gains were simulated using DOE2 software  to evaluate its energy consumption in different urban microclimates. Weather data from two weather stations were used: in Rio de Janeiro – Santos Dumont local airport and Antônio Carlos Jobim International Airport – and in Florianópolis  – Hercílio Luz  International  Airport  and  LABSOLAR at Federal University of Santa Catarina. One prototype was designed to be more sensitive to the external environment and the other, less sensitive.
