Abstract
The integration of human factors into passive building design is still embryonic. This paper presents the attributes and sub-attributes of a user centred passive building design model [UCPBDM] that are deemed indispensable in designing buildings that respond to the constantly evolving user needs. In the first part of this paper, the theory of user centred design based on 13407 and ISO 9126 standard is reviewed. The second part, describes the concept of UCPBDM and the relationship between its components. The final part of the paper introduces the attributes, sub-attributes of the UCPBDM. The numbers of these factors are more than 132 sub-attributes. Thus, the elicitation and classification of the users' factors into homogenous sets will facilities their use by designers. These sets of attributes can be used to assess the design at the early stages for its compliance with en user needs.
