Assessing and reducing the whole-life carbon emissions (WLCE) of buildings is essential to achieving global climate targets. Although many studies have examined building WLCE, there a lack understanding variability WLCE for large number similar in proximity key influencing factors. We fill these knowledge gaps by quantifying 145 residential properties Cornwall, UK, following methods recommended official standards guidelines using actual electricity consumption recorded sensors, then analysing correlations between range factors related their occupants. found significant variations among properties, ranging from 21 193 t CO2eq, with intensity 0.5 2.6 CO2eq/m2. There are strong two factors: floor area occupants, followed bedrooms, type property, window frame material, heating system, age main occupant, glazing, loft insulation thickness. This suggests that both attributes occupant characteristics can result proximity. Therefore, design lifestyle need be considered when developing strategies reduce WLCE.

Abstract To reduce the environmental effects caused by building construction and operation, life cycle assessment (LCA) is increasingly applied. In recent years, national regulations have implemented LCA requirements to support impact reduction. A key element in these are benchmarks which allow designers compare their designs with reference values. This study aims develop bottom-up that represent range of results achieved conventional Flanders, Belgium. For this purpose, investigates potential using a database energy performance calculations. Specifically, considers 39 residential buildings identified as representative Flemish 2015–2016, applying modifications establish scenarios still relevant 2025. The assessed Belgian tool TOTEM calculate an aggregated score based on European product footprint (PEF) weighting approach including 12 main categories. addition score, climate change (CC) indicator analysed individually. view benchmarks, variations were applied original terms heating system materialisation. variation included changing gas boilers electric heat pumps comply upcoming (2025) regulations. materials three sets compositions generate wider spread basis for benchmarks.
