A modular: loop-based approach to HVAC energy simulation and its implementation in EnergyPlus | 1999 | English
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.
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 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.
Bringing simulation to application: some guidelines and practical recommendations issued from IEA-BCS annex 30 | 1999 | English
Simulation tools are not yet used as much and as well as they should all along building life cycle ( BLC ). Most important decisions are still taken almost without using these tools.
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.
Comparison of reproducibility of a real cav system by dynamic simulation HVACSIM+ and TRNSYS | 1999 | English
It is necessary to use the dynamic simulation program to evaluate the dynamic characteristic of the HVAC system.
A practical example of the CHAT_D software application for predicting the risk of thermal disconfort in a house equipped with a cooling floor | 1999 | English
The CHAT-D software environment was developed by the Electricity Applications in the Residential and Commercial Buildings Branch, of the research and development division of EDF (Electricité de France). Our main objective is to ensure the well-bei
An evaluative method for high-perfomance window system and window side radiation environment | 1999 | English
A study was performed on a method to evaluate performance of window system necessary to satisfactorily maintain the window side radiation environment in a glass building.
A comparison of methods to estimate hourly total irradiation on tilted surfaces from hourly global irradiation on a horizontal surface | 1999 | English
A combined analytic and case-based approach to thermal comfort prediction in buildings | 1999 | English
Despite the obvious importance of thermal comfort in the design of indoor environment, it has not been effectively integrated with design decision support tools.
A development of a HVAC experimental chamber and its numerical model, "Numerical HVAC experimental chamber" on a computer | 1999 | English
We first developed an actual HVAC experimental chamber including an air distribution system, an air handling unit, fan coil units, and control systems.
A comparative study of HVAC dynamic behavior between actual measurements and simulated results by HVACSIM+(J) | 1999 | English
A dynamic simulation of the HVAC system is being paid attention because of the development of the computer technology. Authors examined the reproducibility of HVACSIM+(J).
A case study of the energy performance of an office building with double-envelope and atrium | 1999 | English
This paper presents an investigation of the energy performance in an office building in Daejeon, Korea. The office building has a south-facing glazed double envelope and a rectangular atrium.
The IMAGE (IMplementation of Advanced Glazing in Europe) project was funded by the European Commission and involved glass manufactures, onsultants and research organisations (see acknowledgements).
