HAMER, W.; BOOYSEN, W.  and  MATHEWS, E.H.. A practical approach to managing uncertainty in the measurement and verification of energy efficiency savings. S. Afr. J. Ind. Eng. [online]. 2017, vol.28, n.3, pp.128-146. ISSN 2224-7890.  http://dx.doi.org/10.7166/28-3-1850.

Measurement and verification (M) is fundamental in determining the impact of energy efficiency (EE) interventions. However, accurately quantifying the EE savings on complex industrial systems can present several technical challenges. It is of critical importance that these challenges be practically addressed within regulatory requirements when applying for tax-based EE incentives. In this study, the key uncertainties affecting the M of Section 12L EE tax incentive applications are identified. A novel approach provides practical guidelines to manage and mitigate uncertainty. This approach ensures that reported savings are a fair and compliant reflection of the actual savings achieved. The presented case studies show that uncertainty can affect up to 30 per cent of reported savings. This emphasises the significant impact of uncertainty, and quantifies the benefit of compliant uncertainty management. Ultimately, this study provides valuable insight into the practical implementation of tax-based directives intended to stimulate sustainable development.
