Abstract
Purpose: The sustainable green movement is significantly gaining momentum around the globe and South Africa needs to follow suit. However, such a movement needs to be significantly tested. It is therefore essential to present both foundation and supplementary research in the primary concepts within this topic in order to lay the groundwork for future analysis. The purpose of this paper is to analyse the cost-effectiveness of the heat recovery ventilation (HRV) technology incorporated within Lincoln on the Lake, against a direct-expansion (DX) ducted system of conventional practice utilising the life cycle cost analysis (LCCA) to determine if the sustainable option is the better choice. Design/methodology/approach: This paper is a case study, based on a green building in KwaZulu-Natal, South Africa using a ten step life cycle cost analysis. Findings: In terms of the LCCA performed at Lincoln on the Lake, this case study has found that sustainable measures were far more cost effective over the 20 year study period than that of the comparable conventional system. The life-cycle cost analysis tool has provided a simple, uniform and predetermined manner for which the life-cycle costs of sustainable designs can be successfully quantified. Originality/value: The value which sustainable building practices can pose, has not been fully realised among clients and professionals within the South African construction industry due to lack of proof that value incentives do exist. This paper, therefore, emphasizes that savings can be made over the long term by going the sustainable route.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
