Fault detection and diagnosis on HVAC variable air volume system using artificial neural networks | 1999 | English
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.
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.
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.
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
This paper reports on two case studies that explore the current use of computational tools in building design scenarios.
This paper presents the process followed for defining the features of the next-generation HOT2000 simulator, and the conclusions drawn at the workshops, concerning the most appropriate modelling approaches.
The potential of building energy simulation is now well recognised and the use of the technology by progressive energy sector companies is growing. The success of any building performance assessment hinges on the capabilities of the tool, the coll
For effective energy use and level off electricity demand throughout the day, thermal energy storage system is getting popular in HVAC systems in Japan. Load profile prediction can provide information to plan optimal operation, and now, various pr
Simplified equations are established to estimate the energy consumption for the heating and cooling of residences, with the coefficients like air-conditioning area rate, air-conditioning-hour rate, etc..
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.
Effect of sweat accumulation in clothing on transient thermophysiological response of human body to the environment | 1999 | English
The experiments involving clothed subjects are conducted to reproduce the situation in which people enter an air-conditioned room just after sweating, and analyzed using a combined model, which consists of two-node model for thermophysiological re
IDA Indoor Climate and Energy is a recently developed tool for building performance modelling and simulation. It represents a new generation of BPM software in several ways.
Current state-of-the-art of integrated thermal and lighting simulation and future issues | 1999 | English
This paper describes a simulation based method for the integrated performance appraisal of buildings incorporating daylight utilisation technologies.
This paper explains the development of a dedicated configuration tool for the HVACSIM+ simulation environment. This computer-based tool eases configuration by exploiting a visual metaphor of a simulation subject.
Enhancing and extending the capabilities of the building heat balance simulation technique for use in EnergyPlus | 1999 | English
With the advent of the computing age, heat balance based techniques for simulating thermal loads in buildings became a reality for architects and engineers.
Many recent, moisture-originated failures in low-rise residential and high-rise residential/commercial buildings have put a significant pressure to change construction codes in North America and Europe.
