The methodology for calculating the SRI rating of a building is based on the building’s readiness to accommodate “smart-ready services”.
Smart-ready service catalogue
A “smart-ready service catalogue” refers to building services that are categorised into 9 technical domains
- domestic hot water
- controlled ventilation
- dynamic building envelope
- electric vehicle charging
- monitoring and control
Such smart-ready services are enabled by a combination of smart-ready technologies, but are defined in a technology-neutral way, such as ‘provision of temperature control in a room’.
For a given building, all smart-ready services are assessed against the following desired impacts of smart buildings:
- energy efficiency
- maintenance and fault prediction
- health, well-being and accessibility
- information to occupants
- energy flexibility and storage
The result of the smart-ready services assessment is aggregated into an overall SRI score, which expresses how close the building is to maximum smart readiness. In addition, specific scores on each of the 3 key functionalities of building smartness are calculated.
