Methodology

Heat Stress

< Back to methodology

This dataset provides insight on the relative land surface temperature of the area your property is situated, and thus the property’s susceptibility to heat stress. Since the data is historic and provides an overview of susceptibility, it is assumed that areas that are cooler today are likely to remain relatively cooler in the future as average temperatures rise due to climate change. Similarly, areas that are consistently hotter today are likely to become even hotter in the future.

Why should I care about this?
As climate change brings hotter temperatures and more frequent heat waves, buildings originally designed for comfort in milder climates can become susceptible to heat stress, trapping excessive heat inside and creating an unhealthy and potentially dangerous living conditions for occupants.

How we use our data
The classification is based on the maximum aggregate risk of areas of 2k square metres of a base grid that the property intersects. If the maximum intersecting risk is "low" or "very low", the property will be labelled "suitable" and a green traffic light is assigned, if "medium" or "high" the property will be labelled "possibly_suitable" and an amber traffic light assigned, and if "very high", the property will be labelled "possibly_unsuitable" and a amber traffic light assigned.

Available Outcomes:

Suitable

The property is in an area classified with 'very low' or 'low' heat hazard, meaning it generally stays cooler than surrounding areas. As a result, the risk of high heat stress during heatwaves is likely low or very low.

Possibly Suitable

The property is in an area classified with 'medium' or 'high' heat hazard, meaning it generally stays hotter than surrounding areas. As a result, the risk of high heat stress during heatwaves is likely elevated.

Possibly Unsuitable

The property is in an area classified with 'very high' heat hazard, meaning it generally stays hotter than surrounding areas. As a result, the risk of high heat stress during heatwaves is likely very high.

Data Unavailable

  • Recommend to the property owner that they may want to consider their retrofitting options. For a personalised retrofit report, please visit https://martello.greenval.co.uk/

  • Consider an insulation survey to determine reduce heat energy flow.
  • Strategically plant native trees and shrubs to create shade. Focus on south-facing walls and areas receiving direct sunlight. Consider the effect that this decision may have on ground stability in the area.
  • If you have a flat roof or suitable wall space, consider installing a green roof or vertical garden.
  • Encourage climbing vines on walls to create shade and add greenery. Consider which are the best plants to reduce damage to your home.
  • Implement reflective window coverings, like blinds with a white backing. Opt for light-coloured paints and roofing materials.
  • Seal air leaks around windows, doors, and other openings. Upgrade to energy-efficient appliances to reduce and track heat generation within your home.
  • Consider replacing paved areas like driveways and patios with permeable materials like gravel or pavers with gaps, allowing rainwater to infiltrate the ground and reducing heat absorption.
