For improving feedback about thermal simulation results from engineers to architects, it is desirable to present them in the three-dimensional context of the building.
Development of an optiml operational planning system using an object-oriented framework for energy supply plants | 1999 | English
An optimal operational planning system with a userfriendly interface using an object-oriented framework is developed for the purpose of determining operational strategies of energy supply plants in a simple and rational manner on personal computer
Estimate for optimum volume of rock bed and air flow rate for an air-based solar heating system | 1999 | English
In this paper, an approach to the optimum volume of rock bed, its charged thermal energy and the optimum air flow rate for an air-based solar heating system in charging mode is presented.
The ISE (Intelligent Simulation Environment) concept, developed by CSTB since the early nineties, has been applied to the development of various Simulation Environments (such as IISiBat III for TRNSYS or IISiBat II for COMIS).
The cooling effect caused by long wave radiation between the roof surface and the sky is studied here. The external surfaces may cool down below the dew point of the air and the condensation may form [1]. Typically, the covering of cold roofs has
The convective heat transfer coefficient at an outer ambient wall with a window exposed to natural climate was measured in a room with and without furniture.
One central idea of building simulation is to visualize calculated datavalues embedded in an in herently three dimensional building shape.
Determination method of coefficients and its problems in the simulation of urban air temperature based on one dimensional heat budget model | 1999 | English
It is required that the urban air temperature is estimated on the average and macroscopically for studying the urban thermal environmental problems in summer.
Many of the popular building energy simulation programs around the world are reaching maturity– some use simulation methods (and even code) that originated in the 1960s. For more than two decades, the U. S.
The high thermal insulation of housing construction has been spreading all over Japan, for the improvement of indoor environment and the efficiency of energy consumption.
Energy Conservation Buildings are very effective for restraint of global warming, because they can reduce CO2 emissions in building operation, which account for 70% of Life Cycle emissions.
Fault detection and diagnosis on HVAC variable air volume system using artificial neural networks | 1999 | English
Abrupt faults on HVAC components as blocked dampers or broken fan belt can be successfully detected by methods based on logic rules.
Industry foundation classes and interoperable commercial software in support of design of energy-efficient buildings | 1999 | English
Interoperability among software tools that are used in building design can make the use of building energy simulation tools more frequent and more effective.
A building simulation program has been developed and a model of a standard Swedish single family house has been built up. The model uses an explicit finite-difference method to calculate the temperatures of the next time step.
The Florida Solar Energy Center (FSEC) is developing a new software (EnergyGauge USA) which allows simple calculation and rating of energy use of residential buildings around the United States.
This paper reports on two case studies that explore the current use of computational tools in building design scenarios.
This paper is focused on the development of measuring equipment of Effective Leakage Area (ELA) by AC pressurization method. The formula to design the measuring system is derived according to the governing equation of the leakage, e.g.
Evaluation of energy performance of an existing house in montreal using four energy analysis software | 1999 | English
The purpose of this study was to evaluate the capabilities of four energy analysis software to predict the energy performance of an existing house. The discussion covers: (i) the modelling-related issues, and (ii) the impact of modelling accuracy
