An IFC‐based space analysis for building accessibility layout for all users

Abstract

An accessible or inclusive building design does not disable any user; it should enable the independent and equal use of a facility by all. With the introduction of the Disability Discrimination Act 1995 (DDA), the consideration of issues such as access and inclusive design become even more important. Space analysis is an important aspect of the current accessibility assessment. Existing space analysis techniques, such as space syntax, have tackled the local and global accessibility of a building layout using graph theory. However, there are difficulties in the automatic transfer of design information from architectural drawings into a space analysis tool. With the recent development of the building information model and Industry Foundation Classes (IFCs), it is now possible to automate the transfer process. This paper demonstrates the automation process and how it can be used in accessibility analysis.
