As the heatwaves of recent months have tragically demonstrated, the threat of overheating in buildings is a very real and deadly issue. With experts warning of a potential crisis, England risks repeating the mistakes of the past, creating a new generation of 'death trap' structures.
The recent heatwaves in England and Wales have highlighted the vulnerability of many, with research indicating a shocking number of deaths. Yet, despite the growing concerns, local plans seem to fall short in addressing this critical issue.
The Gaps in Local Planning
Only about half of the local plans currently being developed require new buildings to have cooling or ventilation strategies, a worrying statistic. While the intention to include green infrastructure is there, with nearly all councils expressing this desire, the implementation is lacking. Only a fraction of these councils are utilizing recognized tools to ensure the successful integration of green spaces.
Celia Davis, interim director of operations at the TCPA, emphasizes the urgency of the situation, stating, "This is a matter of life and death." She further highlights the disconnect between the ambitious aims of local authorities and the actual outcomes, a concerning gap that needs to be bridged.
The Future Homes Standard: A Step Forward, But Not Enough
The government's "future homes standard" aims to regulate how houses are built from 2028 onwards, focusing on energy efficiency and temperature control. However, this standard excludes crucial buildings like schools, hospitals, and care homes, leaving them vulnerable to overheating.
Dan Slade, head of research and practice at the RTPI, points out the limitations of this standard, emphasizing the need to consider the surrounding environment. He highlights the issue of permitted development rights, which allow for the conversion of offices into dwellings without the necessary regulations, potentially creating more glass box structures prone to overheating.
The Role of Green Spaces and Trees
The Woodland Trust's report adds another layer to this discussion, advocating for the strategic planting of trees near housing developments. Their findings reveal that over 11 million people in the UK live in areas with inadequate tree cover, with those on low incomes disproportionately affected. England's tree canopy levels are among the lowest in Europe, with only a third of urban dwellers enjoying the recommended minimum tree cover.
A Call for Action and Improved Standards
The RTPI report, while not specifically addressing air conditioning, emphasizes the importance of green space factors and best practices in planning. A government spokesperson acknowledged the need for action, stating that national building regulations and planning policies aim to minimize unwanted heat in new homes. They also mentioned a review of relevant building regulations to address the issue of overheating in converted commercial buildings.
In conclusion, the threat of overheating in buildings is a complex issue that requires a multi-faceted approach. While progress is being made, there is still a long way to go to ensure the safety and well-being of all, especially the most vulnerable, during heatwaves. It is crucial that we learn from past mistakes and take proactive measures to create a more sustainable and resilient built environment.
