Sustainable Dunblane was awarded funding from the Government’s Climate Challenge Fund to study ‘Hard to Treat’ Housing in Dunblane which represents 42% of Dunblane Community Council’s housing stock. We undertook energy assessments of 18 houses using RdSAP, SAP, NHER and PHPP. We also undertook airtightness tests and thermal imaging to confirm u-value assumptions.
Whilst there were no discernible differences between the types of property, we did establish that each different survey method used to model the houses energy performance gives a significantly different result. This leads to natural speculation about which is the most accurate, which we have tried to answer in the full report.
