Ductwork pressure loss determination utilizing building information model

Abstract

Building design created as an information model contains not only information formated during building geometry creation but also additional information filled in by a designer. The data can be used further as well as applied in building geometry analyses. One of these are analyses of pressure loss in air-handling units. Such analyses take the advantage of both created geometric parameters, and basic physical variable. These analyses can be carried out directly in BIM software without external calculations needed. The main aim of this article is to describe utilization of information in building model leading to obtain pressure loss in air-handling units.Building design created as an information model contains not only information formated during building geometry creation but also additional information filled in by a designer.
