Dynamic optimization technique for control of HVAC system utilizing building thermal storage | 1999 | English
The paper describes the development of a su pervisory control scheme that adapts to the presence of degradation faults and minimises any resulting increase in energy consumption or deterioration in occupant comfort Since there is a high deg
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 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.
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 computationally-efficient building thermal model is developed for short-timescale investigations applicable to control system design.
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.
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.
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
The premise underlying this work is that introducing uncertainty considerations into simulation will facilitate risk assessment and that this, in turn, will help to improve designer confidence in simulation. Sources of uncertainty abound in buildi
A method for analysis of controllability of duct systems designed for variable ventilation flow rates | 1999 | English
This paper presents a tool, based on a method using IDA for simulation of duct systems and MATLAB as a pre- and post-processor, to study the controllability of VAV-systems.
A study of the simulation of the visibility of baseballs flying in the dome stadium | 1999 | English
An evaluation system of the visibility of a ball flying is indispensable for the best architectural design and artificial lighting design of a baseball dome stadium, as it is essential to create a suitable visual environment for both players and s
A two-dimensional numerical simulation of airflow around bluff bodies is presented in this study. The two turbulence models, i.e., standard k-e model and RNG k-e model, are employed to predict the flowfield and wind effects on bluff bodies.
A nodal model for displacement ventilation and chilled ceiling systems in office spaces | 1999 | English
A nodal model has been developed to represent room heat transfer in displacement ventilation and chilled ceiling systems.
An analysis of the fresh air load reduction system by using underground double floor space for air conditioning | 1999 | English
This paper presents a feasibility study of a fresh air load reduction system by using an underground double floor space. The system was introduced into a real building (Aichi Children’s Center in Japan) and was examined by the field measurement.
