Renovation Pathways: - Method and assumptions

The NPV reflects the time value of money for the cash flow (future benefits of bill savings) and the time value of cost of the initial investment (current costs). [...] The price is the standard tariff rate of the plan with the highest value score out of 10. [...] o The impact of this limitation is low, as the development of the dataset to re-rate residential buildings to be 'low-performance' makes the sample data relevant for the whole building stock. [...] + The modelling and analysis in this research improves the performance of residential buildings and models achievement of a ‘net zero’ home, from the perspective of operational emissions (emissions related to the use of the building). [...] The methodology does not explore the costs and savings of renovations that might take place in future years, and does not investigate the sequencing of upgrades for all of the Australian housing stock.
