SUSTAINABILITY-DEMOLITION OR REFURBISHMENT

Since 2003 the UK has adopted demolition rather than refurbishment to regenerate its ageing social housing stock. However, this neither helps with meeting energy and climate-change targets nor addresses social needs, according the latest issue (163 DP4) of the ICE’s Urban Design and Planning journal.

Anne Power of the London School of Economics and Political Science says, ‘The demolition or refurbishment of older housing has been an active policy area since the late 1880s in the UK, when the government first authorised the statutory demolition of unsanitary slums. The debate on demolition and new building has been intensified since 2003, with UK government proposals for large-scale clearance and new construction.’

After examining evidence on whether demolition reduces energy use in buildings - which account for half the UK’s carbon dioxide emissions - Professor Power concludes refurbishment offers a more achievable and socially beneficial route.

‘Refurbishment offers clear advantages in time, cost, community impact, prevention of building sprawl, reuse of existing infrastructure and protection of existing communities,’ she says. ‘It can also lead to significantly reduced energy use in buildings in both the short and long term.
