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.
This paper describes a design tool, 'Condensation Targeter', for assessing condensation risk in dwellings and the effect of remedial measures thereon.
Recently, the more accurate comparisons between the existing building behaviour and the simulations have shown that a more realistic model of the whole system has to be considered.
Computer simulation/end-use metering or "can we count on energy savings estimates in designing demand-side programs"? | 1989 | English
In 1937, Congress created the Bonneville Power Administration (Bonneville) to serve as transmission and distribution agent for electricity generated by the Bonneville Dam.
In a paper presented at the 1985 predecessor of this conference, I maintained that current PC microcomputer technologies provided the opportunity to develop a new generation of graphically oriented, interactive building modeling programs.
A summary of building energy analysis and design tool evaluation results from IEA task VIII | 1989 | English
This paper summarizes the results of numerous building energy analysis and design tool evaluation exercises carried out under lEA Task VIII: Passive and Hybrid Solar Low Energy Buildings.
Much effort has been devoted over the years to advance Building Performance Simulation (BPS) by improving algorithms and by extending the simulation domain to daylighting, acoustics, and indoor air quality.
In thermal simulation codes for buildings, aeraulic transfers are computed either with very simplified models (fixed air distribution) or with sophisticated models (based on the computation of the pressure fields).
In order to assess the applicability of a more modular approach to the development of building thermal analysis programs, this paper begins with a review of some of the basic numerical methods used in simulation.
