What’s changed Affects results
-
29 July 2026
Adds a District Heating / Cooling emission-factor disclosure row and widens the vacancy options to cover partial vacancy extrapolated to full occupancy. Accredited Service Providers complete this table as part of their deliverables.
-
29 July 2026
Blueprint schema, Blueprint Markdown, reference fixtures, and the expected-outputs summary regenerated from the v1.1 workbooks. The schema now states that the district cooling factor is held flat, and the fixtures carry the v1.1 asset set and results.
-
28 May 2026
District cooling emission factor is now held flat through 2050. Previously it declined over time, coupled to the grid (the same as district heating).
-
28 May 2026
Carrier factors refreshed to the UK Government 2025–26 conversion factors. Added biogas, wood fuels, and a separate North America carrier set (EPA-sourced).
-
28 May 2026Assessment Guide v1.03
Methodology guide refreshed and aligned with the current Pathways and datasets.
-
30 Apr 2026CRREM Library v2.05
Initial open-access release: Global Pathways, emission factors, climate-zone lookups, Assessment Guide, Technical Blueprint, and Worked Examples.
