The London Assembly Planning and Regeneration Committee has published a new report called Retrofit vs Rebuild? which asks how decisions are made to either retrofit or rebuild properties and the carbon implications for both. In London, buildings account for an estimated 68 per cent of the city’s carbon emissions. These emissions arise from the construction, operation, and demolition of buildings. The report claims that, if London is to meet the Mayor’s 2030 net zero target, there is an urgent need to reduce emissions from buildings and to retrofit both housing and commercial stock. (more…)

The UK Green Building Council (UKGBC) has launched new guidance on retrofitting large office buildings. Setting out the most cost- and carbon-effective retrofit measures in the immediate and longer term, the guidance reframes retrofit as an iterative process rather than a standalone project. UKGBC has found that significant opportunities are being missed by office investors, owners, and occupiers who do not have clear strategies to retrofit offices in place. Firstly, through missing the “easy wins” –low cost, low disruption measures that reduce energy consumption – and secondly, through missing key “trigger points” in lease and maintenance cycles that facilitate easier, more efficient retrofit.

Progress on the decarbonisation of real estate portfolios is being held back by a lack of understanding and collaboration between property owners and occupiers, according to a new report from the Urban Land Institute C Change programme. If better alignment between the two parties is not prioritised, it has the potential to increase total emissions from the built environment over the medium to long-term as real estate decisions are often medium to long-term commitments, according to the authors.
