Description

The Smart Readiness Indicator (SRI) is a common EU scheme established by the European Commission with the recast of the Energy Performance Buildings Directive (EPDB) for rating the technological readiness of buildings. The SRI indicator's structured assessment schema is used to measure and rank buildings' smartness, and help monitor its evolution over time. Increasing the level of functionality of a building's embedded service is associated with an increase in SRI level. This can be beneficial across multiple impact areas., but it remains to be proven to what extent it is also beneficial in terms of overall reduction of the environmental impacts. Within this paper, we identify the key methodologies and tools or indicators which can influence the SRI technical domains (heating, cooling, electricity, etc.) and explore how they are linked with relevant life cycle impact assessment (LCIA) categories (such as global warming potential, water footprint, land use, etc.). Furthermore, we discuss to what extent improvements in these technical domains impact (negatively or positively) the building performance. As per SRI specification categories, two distinct use cases can be considered: (1) residential buildings, and (2) larger facilities. Within the scope of this article, we will focus on the residential buildings use case. We then identify and discuss how life cycle assessment (LCA) indicators are in synergy or not with the SRI technical domains. The challenges and limitations of this assessment are highlighted. As an example, we present a hypothetical case study for a family house, where the SRI evaluation was carried out. Using a simplified model, we then evaluate the expected net environmental impacts linked with this increase of building smartness.
