Based on ISO attributes and sub-attributes our proposed user centered passive building
design conceptual model is conceived. The purpose of our model is to help the architect
to ensure that all users’ needs are incorporated into the design of passive buildings.
However we have replaced main attributes of efficiency and portability with performance
and flexibility respectively. The two terms are selected because their common usage in
the building industry
.
The following sections explain how we developed our model based
on the ISO guidelines and system theories.
Integration end user into passive design
The passive design attributes that we adopted for this study are six main attributes. Each
one of them is composed from several sub-attributes measures that can assist the
designer to integrate the user needs into passive building design solutions as shown in
figure 7. Passive design human attributes are defined in our work as [Factors that
captures the needs, wants and limitations of end users in relation to functionality,
performance, maintainability, reliability, usability and flexibility]. The sub-attributes are
extracted from the literature review and case studies. Each main attribute and its sub-
attributes are explained in the following section.
Passive design Functionality:
This attribute is defined in our research as [
A set of attributes that relate to operability
and compliance of passive design strategies to regulation standards and user
operational efficiency
]. Functionality is formed from five sub attributes, which are (1) Site,
Orientation and Vegetation (2) Building form (3) Space planning (4) Roof (5) Facade and
envelope. The attributes are measured by various determinants, which are extracted
based on an extensive literature review from three passive design strategies, i.e.,
lighting, ventilation and heating. These design drivers can support the architect to assess
the functionality of passive design solutions. Each function should perform as required
by the end-user.
Passive design performance:
Our definition of this attribute is developed based on ISO 9126. We propose to define
passive design performance as
[
A set of determinants that measure passive design
functions performance under stated user conditions
]. This attribute is composed of 7
sub-attributes, which are 1) Site performance, (2) Space performance (3) Thermal
comfort (4) Ventilation (5) Lighting (6) Acoustic (7) Adequacy Consumption and
Strategies. These indicators are categorised based on the literature review. The
categories are selected to maximise the level of performance functions.
