This paper describes a control scheme with fault detection capabilities suitable for application to HVAC systems. The scheme uses static simulation models of the system under control to generate feedforward control action, which acts to supplement a conventional PI(D) feedback loop.

This paper describes the development, implementation, and evaluation of a computational tool for the comprehensive support of the lighting design process.

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). As current program could not calculate the object system, it was the new component model corresponding to a model system was developed. As the result, it was shown that HVACSIM+(J) have enough reproducibility and possibility to generate the database for the fault detection and diagnosis, FDD, by comparing the simulated results and the measurements.

Despite the obvious importance of thermal comfort in the design of indoor environment, it has not been effectively integrated with design decision support tools. The reasons can be attributed in part to an absence of modular and flexible software architecture that facilitates dynamic data transfer between energy performance, lighting simulation, and thermal comfort modules.

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. During the preliminary design of the building, a study was conducted by the research team in order to achieve the annual energy consumption per unit area of the building under 240 Mcal/m2-yr. A number of building designs and HVAC system variables were analyzed in terms of energy performance.

We first developed an actual HVAC experimental chamber including an air distribution system, an air handling unit, fan coil units, and control systems. This experimental chamber is a real size model of a typical office and has a floor area of 61.44m2.

The U.S. Departments of Energy and Defense (DOE and DOD) are jointly developing EnergyBase, a new building energy simulation tool that builds on the capabilities of BLAST and DOE-2.

The   purpose of our research deals with the description of a methodology for the definition of specific weather sequences and their influence  on the energy needs of HVAC system. We’ll apply the method on the tropical Reunion Island. The  methodological approach based on a detailed analysis of weather sequences leads to a classification  of climatic situations that can be applied to the site. These sequences have been used to simulate  buildings and air handling systems thanks to a thermal simulation code, CODYRUN.

Stadium Australia is to be the centrepiece of the year 2000 Sydney Olympics. The architects aimed to minimise energy consumption by incorporating passive design measures which would provide ventilation, natural cooling and warming and daylight.
