Heatproof Homes: Designing the Apartment of the Future for a Warmer World

2024年は観測史上最も暑い年となり、猛暑は今後さらに深刻化する見込みです。都市のアパートは特に熱がこもりやすく、住まいの設計そのものが命を守る鍵に。断熱・遮熱・通風を活かした未来の住まい方を考えます。

In the future, a good apartment will need more than low rent or a nice view. It will need to stay safe during long, hot summers. The World Meteorological Organization says 2024 was the warmest year in the 175-year record, about 1.55°C above the 1850–1900 average. The World Health Organization warns that heat stress is already a leading cause of weather-related deaths, and climate change will make extreme heat more frequent and more intense. Hot nights are also dangerous because the body cannot rest well from the heat. (wmo.int)

Apartment design matters even more in cities. The U.S. EPA explains that cities become “heat islands” because buildings, roads, and other hard surfaces absorb and give back more heat than trees, soil, or water. This means a city apartment can stay hotter than nearby rural areas. At the same time, global demand for cooling is rising fast. UNEP says that, under current policies, cooling equipment around the world could triple by 2050 and use more than twice as much electricity as today. (epa.gov)

So what kind of apartment can fight future heat? Experts first point to passive cooling, which means cooling a home by design, not only by machines. UNEP lists insulation, natural shading, ventilation, and reflective surfaces as key measures, and says better building codes can help spread these ideas. The U.S. Department of Energy also says that good insulation, efficient windows and doors, shading, and ventilation can keep homes cool with low energy use in many places. Night air can help too: natural ventilation lets cooler air enter and hot air leave. (unep.org)

Air conditioners will still be necessary in some climates, but they should be the last step, not the first. Cool roofs can lower the heat that enters a building and cut peak cooling demand in air-conditioned homes. When active cooling is needed, heat pumps are one efficient choice for both heating and cooling. If we start designing stronger apartments now, future summers may still be hard, but our homes can be much safer and more comfortable. (epa.gov)
