Research Highlights Building Strategies for Heat Protection
- Research at the Baumit VIVA research park in Wopfing, Austria, indicates that insulated solid construction can significantly mitigate indoor temperature increases during heatwaves, with insulated houses being up to 2°C cooler than uninsulated ones during a 2019 heatwave.
- Austria experienced its hottest summer in 260 years in 2026, with temperatures 2.6°C above the 1991-2020 climate average, and a new national record of 41.2°C was set in Bad Deutsch-Altenburg on August 5th.

As Austria faces increasingly hot summers, with 2026 marking the hottest in 260 years and temperatures reaching a record 41.2°C in Bad Deutsch-Altenburg on August 5th, research into effective building strategies for heat protection is becoming critical. The Baumit VIVA research park in Wopfing, Austria, has been at the forefront of this effort, utilizing 13 test houses to gather data on how different construction methods and materials perform under extreme heat conditions.
One significant finding from a 2019 heatwave, where temperatures reached around 30°C, revealed that an insulated house was 2°C cooler than an uninsulated one. Further studies at the VIVA park have demonstrated that solid houses equipped with external thermal insulation composite systems (ETICS) can maintain comfortable indoor temperatures, often without the need for air conditioning, even during heatwaves. This combination of thermal insulation and substantial wall mass prevents rapid heating, offering a crucial advantage during prolonged periods of high temperatures.
The research also addresses concerns about renovating older buildings, showing that proper insulation can improve indoor climate and reduce humidity peaks. For instance, a breathable insulation system allowed humid brick walls to dry more quickly after renovation. The importance of insulation extends beyond just temperature regulation; it also contributes to sound insulation and can help maintain stable indoor temperatures during heating outages in winter. These findings are particularly relevant as heatwaves are increasingly impacting health and well-being, especially in urban areas where apartments can become “ovens,” with temperatures exceeding 30°C even at night.
