A Classification of Built Forms

Abstract

A classification of built forms is presented. It is based on a study of buildings surveyed at 3350 addresses in four English towns and has been designed for use in the national Non-Domestic Building Stock (NDBS) database developed for the Department of Environment, Transport and the Regions. As the prime use of the database is in energy analysis, the classification focuses on the external envelopes of buildings. (Materials of construction, servicing systems, and activities are classified separately.) Built forms are distinguished according to two main criteria: the broad “texture” of their internal subdivision; and whether they are daylit or artificially lit.
