On the natural displacement ventilation flow through a full scale enclosure, driven by a source of buoyancy at floor level | 2001 | English
In this paper, we present a new method of combining ASHRAE Room Energy Balance Method with 3-d airflow modeling to estimate the thermal comfort conditions of the emerging air- conditioning system that combines radiant cooling and de
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
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
The paper presents a dynamic approach of the validation process of existing building simulation model.
New façades system consisting of combined photovoltaic and solar thermal generators with building insulation | 2001 | English
Most photovoltaic (PV) facades are built as curtain facades in front of thermally insulated buildings with air ducts in between.
This work regards the development and the validation a simplified model for building cooling energy requirement.
The Energy and Environmental Prediction (EEP) model is an environmental auditing and decision making tool for cities, to be used by planners and others in pursuit of sustainable development.
Optimising energy consumption in offices as a function of window area and room size | 2001 | English
Windows allow daylight to enter a space but they also allow for the transfer of heat gains and losses that affect the energy consumption of a building.
A structured, generalized modeling and simulation software is described that enables development and analysis of control algorithms and systems and pre- diction of thermal performance and energy use in buildings.
To meet the requirements of building owners and users in environmental issues, life cycle assessment (LCA) has become an important method to monitor the ecological perspective during design and decision making processes.
This paper presents the multiple-view performance assessment of an existing office building undertaken with an integrated application.
Sim_Zonal: software evaluating indoor temperature distributions and air movements for rapid appraisals - first application to an cell | 2001 | English
This article presents the first application of the Sim_Zonal software, a tool for evaluating indoor temperature and air flow distributions for residential and office buildings.
