Can Salvator Mundi and Zlatan make Built Cultural Heritage resilient? The new role of built cultural heritage (BCH), as an economic asset for development strategies and the widened definition as a concept-, explains today’s affluence of sites. These can only be guaranteed with sufficient heritage funding. Financers’ inducement to fund depends on that heritage’s current value estimation and only highly revered sites qualify for support. Case studies imply that values are incessantly present in BCH and so these can be re-established when the right external conditions, or actions, arise. The assessment i.e. reflects the human perception of values projected onto buildings and not the physical characteristics of the heritage itself. This is why it is possible to modify finance incentive conditions. The Heritage Finance Model, HFM (Pålsson Skarin 2011) could establish that the accelerators determine all aspects, since these accelerators stabilize the values of BCH by revealing the payback capacity of financial commitments to that heritage. The HFM revealed all mechanisms behind cultural heritage financing in theory, but to make the model operational, it is still necessary to create a unit for value that can predict its fluctuations. Value changes are a well-known phenomenon in many industries from real estate, sports and the auction world. The increase in value of Leonardo’s painting Salvator Mundi, which in sixty years rose from 60 dollars to 450 million dollars, is perhaps the most spectacular example from our time. The question is whether it is possible to create reliable common denominators by systematically mapping value changes in widely different contexts. The aim of this study is to investigate the prospects of securing the successful future of built heritage by proposing a unit for value to make the previously designed HFM possible to compute. This model include the acquiring, the economizing and the assuring of cultural heritage funding. The strategy of this inquiry involves studying how the perception of value fluctuated in different situations involving art, sport and built cultural heritage. The study’s contribution is the exploratory analysis of the mechanisms behind value growth which regulate heritage funding including its accelerators, hence introducing new terminology into building conservation instigated by the idiom of economics, which could ease future strategic planning of heritage funding. This study is urgent due to cultural heritage funding in Sweden has fallen dramatically due to weak emotional and financial accelerators, which means the Swedish heritage is at risk of decay
