Abstract
Purpose
The purpose of this paper is to investigate the current level of awareness, usage and advocated benefits of economic performance measures of life cycle costing (LCC) in sustainable commercial office buildings.
Design/methodology/approach
Questionnaire survey to 120 construction professionals was used to gauge the current level of awareness, usage and advocated benefits of economic performance measures in LCC.
Findings
The key findings of the statistical analysis indicated that there is a low awareness and usage of economic performance measures, and revealing the entire value of capital outflow alternatives was the most advocated benefit of its application.
Research limitations/implications
Although the data used in this paper were from professionally qualified members of either the Royal Institution of Chartered Surveyors (RICS), the Chartered Institute of Building (CIOB) and the British Institute for Facilities Management (BIFM), the research is limited in some ways in that it does not cover all the professionals in the construction industry. Nevertheless, all the professionals who responded to the questionnaire have up-to-date level of awareness of economic performance measures in LCC.
Practical implications
The use of economic performance measures helps to make available the information required for building performance. Therefore, economic performance methods in LCC are useful devices for users to appraise and distribute recognisable values from initial costs, operating and maintenance costs to clients in the life cycle of an asset.
Social implications
Value for money for construction products and its facilities should not be viewed only in terms of costs to design and construction. Rather, it is vital for corporate occupants and society in general to consider other key variables such as operations, maintenance, renovation, replacement and end-of-life costs.
Originality/value
This study fills the gap in the existing knowledge by addressing concerns over performance measurement to improve the confidence in LCC for sustainable commercial office buildings.

Abstract
Purpose
The purpose of this paper is to explore and rank the benefits and barriers (technological and non-technological) of using Building Information Modelling (BIM) in sustainable building design. It also employs the use of a design tool analysis of a case study using BIM compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North.
Design/methodology/approach
The paper explores the benefits and barriers of using BIM through a literature review. Regression and factor analysis were used to rank these benefits and barriers. A questionnaire was distributed to a sample of 120 practitioners with 69 completing the survey. Finally, the paper employs the use of a design tool analysis of a case study using BIM-compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North riverside.
Findings
The key findings of the statistical analysis indicated that professionals ranked the integrated project delivery as the most established benefit, while the lack of interoperability was ranked the greatest technological challenge. Only three of the attributes of non-technological challenges made statistically unique contributions, namely, training costs and software costs, client demand and potential legal issues. It was also discovered that BIM delivers information needed for environmental performance. In a forward-looking approach, the paper attempts to provide some recommendations that would encourage the continuous application of BIM in sustainable building design.
Research limitations/implications
This paper does not cover all features of BIM functionality, as the scope of BIM is very enormous and the resources of this research were limited.
Practical implications
The implication of the study is that it will assist in exploring and ranking the benefits and barriers (technological and non-technological) of using BIM while proffering recommendations for future use. This research will be of interest to industry practitioners and academic researchers with an interest in building information modelling.
Originality/value
This paper contributes with new outlooks aimed at syndicating sustainability with environmental performance and adds to the limited empirical studies on the benefits and barriers of the application of BIM.
