Theme B: Creating a livable, healthy and environmentally viable citiessolutions. To validate the results, two approaches were employed. The first is tocheck the dominance relationships among the 18 Pareto optimal solutions, and thesecond is to check superiority of the optimal solutions by varying design variables.The first validation method is described below, details of which will not be givenin this paper for want of space. The comparisons between optimal solutions aremade to confirm that every optimal solution from the algorithm is a non-dominatedPareto solution.Comparison of Optimal Design 1 with Design 2 (Table 3): Design 1 has loweroperation costs, whereas Design 2 has lower PD and CO 2 concentration, indicatingthat both designs are non-dominated Pareto solutions whose superiority cannot bedetermined.Comparison of Optimal Design 4 with Design5 (Table 3): Design 4 has lowerinitial investment and operation costs, whereas Design 5 has lower PD and CO 2concentration, indicating that both designs are mutually non-dominated.Table 3: Optimal Designs (Non-Dominated Pareto Solution Set)OptimalDesignHybrid(supply diffuser)Non-Dominated SolutionDesign VariablesSensible HeatExchanger(CMH)Total HeatExchanger(CMH)LR BR DR(X 4 ) (X 5 ) (X 6 )Hybrid(CMH)(exhaust)Initialinvestment(KRW)Objective FunctionsOperationcost***(KRW/Yr)%Dissatisfied(PD)CO 2Concentration(PPM)LR(X 1 )BR(X 2 )DR(X 3 )LR(X 7 )BR(X 8 )DR(X 9 )DR(X 10 )1 0* 0 1** 0 0 0 0 0 0 60 710,000 151,230 17.6 11002 0 0 1 0 0 0 0 0 0 120 710,000 292,450 9.8 8003 1 0 0 0 0 0 0 0 0 120 750,000 292,450 9.8 7004 0 0 0 0 0 100 0 0 0 0 1,000,000 182,400 11.5 9005 0 0 0 150 0 0 0 0 0 0 1,252,900 223,590 7.9 8006 0 0 0 0 150 0 0 0 0 0 1,252,900 223,590 7.9 8007 0 0 0 0 0 150 0 0 0 0 1,252,900 223,590 7.9 8008 0 0 0 0 0 200 0 0 0 0 1,569,700 264,780 5.9 7009 0 0 1 0 100 0 0 0 0 60 1,710,000 333,630 7.4 70010 0 0 1 100 0 0 0 0 0 60 1,710,000 333,630 7.4 70011 0 0 1 0 100 0 0 0 0 120 1,710,000 474,850 5.3 60012 1 0 0 0 100 0 0 0 0 180 1,750,000 616,070 4.1 50013 0 0 0 100 100 0 0 0 0 0 2,000,000 364,780 5.9 60014 0 0 0 100 0 100 0 0 0 0 2,000,000 364,780 5.9 60015 0 0 0 0 100 100 0 0 0 0 2,000,000 364,780 5.9 60016 0 0 0 150 100 0 0 0 0 0 2,252,900 405,970 4.6 50017 0 0 0 100 150 0 0 0 0 0 2,252,900 405,970 4.6 50018 1 0 1 200 250 0 0 0 0 60 4,326,300 731,960 1.9 400LR: Living Room, BR: Bed Room, DR: Dining Room*diffuser not installed, **diffuser installed, ***includes fan energy, heating energy (Oct. – Feb.), maintenance404
