Present research on assessing performance of residential buildings is done for specific purposes and not holistically. The indicators, factors and attributes considered for evaluation are not consistent and are broadly based on knowledge base of the author. The purpose of this research is to identify building performance attributes based on user requirement.

With ISO 6241-1984(E) as a basis for universal acceptance, user requirements have been listed and based on these user requirements, related building performance attributes have been identified. End-user satisfaction is of primary importance to gauge performance of a facility. A quantified approach in evaluation of performance of a facility will enable a facility manager to assess the efficacy of the present policies pertaining to operation and maintenance of the facility. It will also provide valuable inputs to policy makers in initiating measures toward the goal of achieving desired user satisfaction. Performance measurement is done to measure the value created by the services, to justify the investment made in creating the facility or to determine if any additional investments are required for improvement of the facility.

In this literature review, an attempt is made to identify user requirements based on an internationally renowned standard ISO 6241-1984 (E), as a base and group building performance attributes on these requirements. The identified attributes are grouped into physical, environmental and external factors for ease of garnering user satisfaction and subsequent flexibility in assessment of data based on requirement of the surveys carried out for evaluation.

The identified list of user requirement-related building performance attributes is limited to government residential buildings. The research needs validation through a full-fledged user satisfaction survey.

It provides a comprehensive list of attributes for assessing performance from physical, environmental and external factors, enabling wholesome assessment of the performance of buildings. Moreover, as a universally accepted document ISO 6241-1984 (E), forms the basis of the paper, its application is not limited to a region.

Lot of research is happening in the field of assessing building performance. User satisfaction by virtue of being difficult to quantify, it has not found much favor till now. This attempt is to furnish a comprehensive list of building performance attributes that will enable a multipurpose survey which will not be based on perception of the researcher but on a universally accepted document. The premise of research is that end-user satisfaction is of primary importance to gauge performance of a facility.

The purpose of this study is to develop a user-centric facility maintenance model through user satisfaction index linked intervention strategies for public housing.

User requirements are standardized by ISO 6241-1984(E), building performance attributes (BPAs) influencing those user requirements are identified. Selected BPAs are amplified as sub attributes characterizing BPAs. Grouping of BPAs are done to suit established hierarchy of government facility maintenance (FM) agencies. Post validation of BPAs/sub attributes for adequacy, they are ranked and weights assigned through expert survey. Questionnaire designed to garner user feedback based on BPAs and sub attributes to develop a user satisfaction index (USI) that can enable quantification of user feedback. A theoretical framework for interventions is designed which can be enmeshed in existing hierarchy of FM agencies.

84 per cent of expert survey group comprising architects/planners/engineers/facility managers/consultants agreed on adequacy of attributes and 78 per cent endorsed necessity for amplification of BPAs through sub attributes. USI shall facilitate comparison of pre- and post-implementation of interventions. A theoretical framework for FM agencies is developed for interventions.

The FM model presently is limited to application only in public housing. For wider application to other built facilities, choice of BPAs need to made accordingly. As the implementation of interventions and its comparison is likely to take at least a financial year, the theoretical framework can be validated subsequently as a future scope of research.

The biggest implication of this FM model is that the most important stakeholder, that is, end user/occupant gets to register feedback on building performance. This model establishes accountability of government FM agencies and also validates the methods and processes adopted for maintenance of built facilities.

A section of the feedback comprises issues not directly related building envelope but societal issues. This feedback in the long run can become a repertoire of data for administrative agencies to map changing aspirations of government employees with respect to authorization/entitlements.

Quantification of user satisfaction is an inevitable necessity in spite of being a qualitative aspect. This study makes a unique attempt to provide a framework to establish accountability of government FM agencies which is presently non-existent.
