HOT2000™, a residential energy analysis program, is constantly under evolution. New models are added to the program and its user base is ever expanding.
Rational operation of a thermal storage tank with load prediction scheme by arx model approach | 1997 | English
Thermal storage tanks are widely used in Japan mainly to shift electrical energy usage to night time for the purpose of peak demand reduction. However, the operation of the system has not often been accepted with satisfaction in a real field.
A series of linked spreadsheets has been developed for the analysis and modeling of thermal and daylighting effects on the flow of energy in buildings.
This paper describes a recent extension to the ESPr system concerned with the simulation of facade and roof-integrated photovoltaic modules.
Numerical simulation of air flows: an essential tool of comfort optimization of modern buildings and HVAC systems | 1997 | English
The paper deals with the CFD (computational fluid dynamics) application to the comfort optimization of some complex architectural projects in which the physical interaction effects between the building and its environment affect strongly the build
The control strategy of the thermal storage HVAC system gives a large effect to the storage efficiency which dominates the tank volume to a great extent. Authors introduce how the temperature distribution of the tank varies and gives a considerabl
Calibration of hourly energy simulations using hourly monitored data and monthly utility records for two case study buildings | 1997 | English
This paper presents a calibration methodology using only two to four weeks of hourly monitored and monthly utility records.
Dynamic link of light- and thermal simulation: on the way to integrated planning tools | 1997 | English
A method to evaluate the energy demand for lighting on an hourly basis is presented. The method is based on a raytracer and a dynamic modelling of the sky’s luminance distribution.
Methodology for modelling/simulation of an office building equipped with an air-condicioning system | 1997 | English
This article presents a study of a building-equipment coupled system performed at the Gaz de France R & D Division. The commercial building under study is equipped with an air-conditioning installation which includes a gas-fired dual-seJVice a
A case study is used to introduce a two-step thermal demand calculation for buildings in order to take thermal bridges into consideration.
Training new users of simulation programs typically focuses on a single tool–specific techniques for interacting with, creating models, and assessing performance.
New generation of software? modeling of energy demands for residential ventilation with HTML interface | 1997 | English
The paper presents an interactive on-line package for calculation of energy and cost demands for residential infiltration and ventilation, with input and output data entry through a web browser. This is a unique tool.
Passport Plus is a new design tool for building thermal analysis which was developed within the European research project PASCOOL of the European Commission.
Design of air conditioning systems for efficient life-cycle operation using the ZEBRA software package | 1997 | English
Life-cycle design of air conditioning systems requires that plant should be capable of maintaining zone comfort conditions within specified limits, while minimising capital and operating costs.
Integration of computer based modelling and an inter-disciplinary based approach to building design in post-graduate education | 1997 | English
Computer based design aids have much potential to improve the productivity of the design process and provide more confidence in the performance of a building.
Reliable sky luminance models are considered to be conditio sine qua non for accurate computational simulation of daylight distribution in architectural spaces. Toward this end, the paper compares six sky models specifically with regard to their a
Examination of the concept of using 'typical-week' weather data for simulation of annualized energy use in buildings | 1997 | English
This paper investigates the feasibility of using short segments of weather data to simulate annual energy use in buildings.
A numerical and experimental study is performed to analyze the influence of natural convection on heat transfer in a composite system comprising a porous material heated from below and an air space situated above this.
Many building simulation computer programs, originally developed on mainframe computers for research purposes, can now run on the powerful workstation and personal computers that are available to most architectural and engineering firms.
