Computers are currently used for a large variety of tasks in building design and analysis.
A new computer program has been written for comparing the annual energy and economic performances of different window systems in non-residential buildings.
Development of a component program library for building energy simulation: a japanese experience | 1989 | English
This paper describes the concept of developing a component program library for building energy simulation and the current state of its development, which has been made by a working group of theSociety of Heating, Air-Conditioning and Sanitary Engi
The Indoor Air Quality Simulator for personal computers (IAQPC) has been developed in response to the growing need for quick, accurate predictions of indoor air contamination levels.
The analysis of enthalpy control strategies and its application in hot and humid climates | 1989 | English
Air enthalpy control strategy, or often known as free cooling, has been very effective in conserving building air-conditioning power consumptions-in moderate climatic areas.
Perturbations in atmospheric density caused by high rise buildings and their effect on astronomical observations: a case study | 1989 | English
Proposed construction of high rise buildings near the U. S. Naval Observatory in Washington D.C. caused astronomers to ask what effect the heat released by these buildings would have on their ability to make accurate observations.
Experimental studies during the 1940S concluded that heat loss from slab-on-grade floors is proportional to floor perimeter length. More recent numerical investigations, however, indicate that area and shape are also important parameters.
How good are single zone - monthly based - correlation methods for building energy and comfort performance assessment | 1989 | English
Several single zone, monthly based, correlation methods have been developed at a national level , ver the past few years.
Since methods incorporating the time value of money are the only ones that give an accurate picture of life costs of a system, they are the only methods appropriate for the analysis of building lighting systems.
The heat transfer processes occurring in the earth surrounding a building have a substantial effect on the building's energy consumption.
COMBINE is a file utility program developed by Jeff Hirsch of Lawrence Berkeley Laboratories for use with the DOE2.1C building energy simulation program.
In a typical computer-based building energy management system (BEMS) for HVAC applications, pertinent variables such as pressure, temperature, fluid flow rate, valve and damper positions and the open/close status of the flow control devices, are m
The paper presented is based on work done within the IEA ANNEX 10 'system simulation' group.There, eight research instituts discussed and agreed on simulation models for heating and air conditioning components.
Commercial building owners and managers face a complex array of HvAc technology options. Economicanalysis of the options requires consideration of technology characteristics, equipment operatingstrategies, and utility rates.
Today, the development of computer makes the accurate performance analysis of complex system by simulation available for most of the research community, and very soon for every concerned engineer.
Building simulation software alone can sometimes fall short of providing a reliable building model.
In order to create a simulation model of a building, it is usually necessary to make a number of assumptions and/or approximations about the building being simulated.
At the present time several powerful simulation models exist for the assessment of building environmental performance at the design stage. However when used as design tools these models suffer from several fundamental limitations.
Much research has been directed towards development of software environments that allow easy construction of building simulation models of widely varying structure and purpose. For example, TRNSYS has been in use for a number of years.
