The study aims to build up knowledge for collateral exploration of the classical Delphi survey method for assessing the industrial sustainability-related correction factor using a real field study in Nigeria.

The paper elicits the character and the operational approaches using an example study to provide a critical review of the method. It estimates the correction factor for appraisal purposes by transforming expert opinion into a valid group consensus.

The work considers the specific parameters of the method, design and analysis for interpretation to prove the reliability and the validity for the research results. Moreover, it emphasises that the validity of the traditional Delphi research demands cautious theoretical and practical applications by the coordinating researcher. The paper establishes the current validity and effectiveness of the classical Delphi method of foresight and streamlines their efficient implementation for theory building despite its numerous weaknesses.

It explores desirable futures for the method while analysing what is possible and probable.

The aspects of sustainability are often not considered explicitly in property valuation. The purpose of this paper is to investigate the structural relationships between valuers’ support for integration of industrial sustainability into property valuation process in Nigeria and their knowledge perceptions about the potential sustainability benefits.

The paper compares the results of the respondents’ evaluation of the models and indicators for modelling the study population. Data were obtained from 267 real estate firms from three core Nigerian cities. The conceptual framework was developed and pattern matrices for factor indicators were extracted for the predictions and hypothesis testing using the partial least squares–structural equation modelling.

Perceived lowering of risks and cost savings are the significant predictors of the valuers’ support system (BLR→SUP (t=12.181); BCS→SUP (t=2.078)>1.196). The findings challenge the conceptual expectations as prospects of high building value, improved productivity gains and quality of life have no significant factor loadings. Moreover, potential improvement to the quality of life is not a significant mediator.

Testing the knowledge-support systems in sustainability and property valuation could help bridge the knowledge gap in property sustainability studies.

This study presents evidence that can aid in decision making regarding public and private efforts to define sustainability knowledge requirements for the valuers and other stakeholders.

The current investigation finds that there is insufficient sustainability knowledge among the valuers. Thus, these analytical procedures can be used to predict sustainability scenarios at a global level.
