On July 22, 2024, the world recorded its hottest day ever, underscoring critical issues with poorly designed buildings in extreme heat. 

Many homes in hot climates are inadequately designed, lacking proper insulation, shading, and ventilation, which exacerbates indoor heat and increases energy use. 

This poor design not only endangers health but also contributes to higher greenhouse gas emissions. The construction sector is a major emitter and the growing demand for cooling further drives emissions. This creates a vicious cycle: inadequate buildings increase energy use and emissions, which in turn worsen climate extremes and threaten those living in such homes. 

Urgent policy reforms and updated building codes are needed to break this cycle and ensure climate-resilient, energy-efficient buildings.
