In the last seven years, a method has been developed to analyse building energy performance using simulation, in Brazil.
A methodology for the optimal operation of a HVAC system with a thermal storage water tank has been proposed by one of the authors1).
Energy demand of different glazing materials and light control systems for office spaces are analyzed in this paper.
The present work deals with the determination of a mathematical correlation for conductivity in the fully water-saturated state in terms of dry-basis conductivity and porosity.
This paper describes the "Self-aware Buildings" (SAB) project. This is an effort to advance the state of knowledge and technology in the area of environmentally conscious and user-sensitive integrated building control systems.
Measurement and numerical simulation by means of SIMEDIF of a light construction building located in the Argentinean Noethwest | 2001 | English
In this work, the results obtained during the monitoring of a building together with the adjustment curves achieved with the numeric simulation program SIMEDIF are presented.
On the natural displacement ventilation flow through a full scale enclosure, driven by a source of buoyancy at floor level | 2001 | English
This paper presents experimental data for the temperature stratification established within a full-scale enclosure, for the natural displacement ventilation flow driven by a source of buoyancy at floor level within the space with air as the workin
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
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.
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.
