Building archetypes are commonly used to identify areas with energy-inefficient buildings and estimate energy demand at different spatial scales. However, these often rely on conventional occupancy schedules, which fixed uniform throughout the year. This study proposes a new methodology that uses data from Time Use Survey (TUS) extract realistic profiles. The profiles model heat gains due along their interaction lighting heating systems. developed schedules take into account factors such as number of occupants, dwelling types, month year, day Energy simulations were conducted evaluate impact multi-scale residential building scales (postcode, county, national). results showed significantly resulting in approximately 8%–10% variations annual various compared base case. Monthly electricity consumption also 25% 32%, respectively, With more granularity, daily reported 50% 12%, case standard schedules. These highlight importance incorporating for reliable predictions temporal Occupancy-integrated can help policymakers, local authorities, urban planners make informed decisions based actual develop effective recommendations direct retrofit investment policies.

Balancing construction and operational carbon emissions: Evaluating neighbourhood renovation strategies

Journal of Building Engineering, Journal Year: 2024, Volume and Issue: 94, P. 109993 - 109993

Compliance with the global decarbonisation commitments set out in Horizon 2050 undoubtedly involves optimising conditions of housing stock. In this respect, massive energy renovation obsolete blocks southern EU countries holds key for achievement such compliance. This research strives to demonstrate suitability intervention strategies at district scale. For purpose, an innovative methodology that combines open data, Geographic Information Systems (GIS), Urban Energy Modelling (UBEM), and Life Cycle Assessment (LCA) is proposed tested a case study, whilst considering several new-building hypotheses. As approach, study concurrently analyses greenhouse gas emissions arising from both use-related consumption (operational carbon footprint) construction process (embodied footprint). dual perspective provides added value results obtained, since it offers more comprehensive representation reality. Based on LCA UBEM models, unveils entire impact residential use combined either footprint or new buildings. The analysis reveals total emissions, encompassing embodied operational aspects, are lower retrofitting existing buildings when compared construction, up 2050. Remarkably, preference persists even as far 2100. underscores critical importance upgrading stock order achieve ambitious goal net-zero by
