An improved model for reducing the cost of long-term monitoring in Clean Development Mechanism (CDM) lighting retrofit projects is proposed. Cost-effective longitudinal sampling designs use the minimum number of meters required to report yearly savings at the 90% confidence and 10% relative precision level for duration of the project (up to 10 years) as stipulated by the CDM. Improvements to the existing model include a new non-linear Compact Fluorescent Lamp population decay model based on the results of the Polish Efficient Lighting Project, and a cumulative sampling function modified to weight samples exponentially by recency. An economic model altering the cost function to a nett present value calculation is also incorporated. The search space for such sampling models are investigated and found to be discontinuous and stepped, requiring a heuristic for optimisation; in this case the Genetic Algorithm was used. Assuming an exponential smoothing rate of 0.25, an inflation rate of 6.44%, and an interest rate of 10%, results show that sampling should be more evenly distributed over the study duration than is currently considered optimal, and that the proposed improvements in model accuracy increase expected project costs in nett present value terms by approximately 20%. A sensitivity analysis reveals that the expected project cost is most sensitive to the reporting precision level, coefficient of variance, and reporting gm2014 Electrical, Electronic and Computer Engineering Unrestricted 2014-10-27T09:43:44Z 2014-10-27T09:43:44Z 2014-09-05 2014 Dissertation Carstens, H 2014, Improvements to longitudinal clean development mechanism sampling designs for lighting retrofit projects, MEng dissertation, University of Pretoria, Pretoria, viwed yymmdd <http://hdl.handle.net/2263/42443> M14/9/418/gm http://hdl.handle.net/2263/42443 en © 2014 University of Pretoria.
