FAQS
What is the link between the SRI methodology and the ISO52120 standard?
Calculation methodology
Answer:
Many of the SRI services are sourced from EN 15232 “Energy Performance of Buildings — Impact of Building Automation, Controls and Building Management” (module M10) which is the previous version of the ISO 52120-1 standard “Energy performance of buildings – Contribution of building automation, controls and building management – Part 1: General framework and procedures”. This standard is the overarching standard that models the impact of BACS on a building’s energy consumption. The EN 15232 standard has been developed by CEN/TC 247 as part of a series of standards aimed at harmonising of the methodology for the assessment of the energy performance of buildings, called as the “EPB set of standards”.
