Introduction -- Revisions to previous cost estimates in light of finalised technical guidance -- Development scenarios against which costs have been considered -- Estimated costs -- Potential for cost reduction -- Conclusions

Reports the final results of the research done to update and improve cost benchmarks for reaching different performance levels set by the Code for sustainable homes. Has the goal of clarifying the costs in line with the technical guide of the Code for sustainable homes. Reviews Cyril Sweet?s initial cost analysis for specific credits by taking into consideration the technical guidance of the code. Uses chosen development scenarios to provide cost analysis. Presents estimates of costs and savings on utility bills, carbon emissions and use of drinking water of each development type for chosen scenarios.
