This paper describes the methodology and the implementation of DEST, which is a simulation software developed to help the designer during design process. For each design phase, DEST provides corresponding method and program.
The objective of this study is to improve the control performance of Ondol heating system in apartment buildings. For this purpose, prevalent control systems and relevant researches are evaluated.
Assessing the value of typical meterological years built from observed and from synthetic data for building thermal simulation | 1999 | English
Typical Meteorological Years obtained from observed meteorological records have become the de facto data source when evaluating thermal performance of buildings.
Large Eddy Simulation (LES) with a Dynamic Subgrid-scale Model (DSM) is a powerful tool to predict indoor airflow. However, the model needs to average the model coefficient over a homogeneous direction.
An absorption chiller model is developed for HVACSIM+(J). The model simulates dynamic characteristics of the chiller, such as dynamic trends of chiller temperatures and COP.
Calibration procedure of energy performance simulation model for a commercial building | 1999 | English
Calibration with actual data has been considered as one of the most important and difficult part for the systematic energy audit procedure.
A comprehensive approach to modeling and evaluating the visual environment in buildings | 1999 | English
This paper describes the development, implementation, and evaluation of a computational tool for the comprehensive support of the lighting design process.
Within the research context relating to the modeling process of architectural buildings and landscape planning, the CRAI particularly works on the simulation of day-light and artificial illumination. The purpose of this research is to develop a so
Analysis on coupled heat and water transfer through porous materials by thermodynamic energy | 1999 | English
New thermodynamic energy “water potential” based on the chemical potential of a component of mixture gases is defined as the driving force of gaseous phase water flux.
Coupling between a graphical simulation environment simulator and an optimisation algorithm | 1999 | English
The main aim of this study is to derive some simple rules for an optimal management of direct electric heating in residential buildings. Optimal management should minimise the running cost of heating while maintaining comfort, in the case of contr
A modular: loop-based approach to HVAC energy simulation and its implementation in EnergyPlus | 1999 | English
This paper presents the new EnergyPlus HVAC simulation environment, which differs from existing energy analysis programs in three key respects.
We developed a PC-software to estimate thermal environment of a residential house. To make the software practical for non-technical people, the easiness of operation was our main interest in this development.
This paper presents a decision support system (DSS), named Building Energy Code Advisor, that aims to: (i) check if the early design of the exterior envelope complies with Model National Energy Code of Canada for Buildings (MNECCB) [1] requirement
A computationally-efficient building thermal model is developed for short-timescale investigations applicable to control system design.
Object-oriented or modular simulation methods represent a concrete alternative to present monolithic building simulation technology.
The legislation and energy awareness have lead to increased thermal insulation levels in buildings. Consequently, heat flow, between the indoor and outdoor environments, due to thermal bridging is forming an increasing fraction of building thermal
A method to estimate the shading of solar radiation theory and implementation in a computer program | 1999 | English
A general method to determine the shading of direct and diffuse radiation is presented. This can handle an almost infinite number building surfaces and screens of any shape.
A study on the applicability of the time-division hot water supply heating for ondol: the radiant floor heating system in korea | 1999 | English
The typical Korean residential buildings, especially apartment buildings, are furnished with ONDOL – the Korean traditional radiant floor heating system. The buildings are getting more insulated and air tight for heating in hard winter.
