TL;DR
Amsterdam has issued a public advisory for residents to hang curtains outside their homes during a heatwave testing new building designs. The measure aims to help homes built for winter withstand high temperatures. The development raises questions about urban heat management and building resilience.
Amsterdam authorities have officially recommended that residents hang curtains outside their homes to help manage indoor temperatures during a record-breaking heatwave. The city aims to test the resilience of homes built primarily for winter conditions as temperatures soar to 40°C, a phenomenon that is becoming more frequent due to climate change.
The recommendation was issued by the Amsterdam municipal government as part of a broader effort to cope with the ongoing heatwave, which has seen temperatures reach approximately 40°C, according to the Dutch weather service. Officials suggest that hanging curtains outside can provide shade and reduce indoor heat buildup, especially in homes constructed with insulation and materials optimized for cold weather.
Experts note that the unusual practice is a temporary measure to test the effectiveness of building designs under extreme heat conditions. The city’s building standards have traditionally focused on winter insulation, and there is concern that such structures may not perform well during heatwaves. The initiative aims to gather data on how simple interventions like outdoor curtains can mitigate indoor temperatures and improve comfort.
Residents are advised to hang curtains or fabric panels outside windows during the hottest parts of the day, particularly between noon and 4 p.m., to provide shade. The city emphasizes that this is a short-term experiment and encourages residents to share their experiences with the practice.
Implications for Urban Heat Management in Amsterdam
This development highlights the growing challenge cities face in adapting buildings designed for cold climates to withstand increasingly frequent and intense heatwaves. If effective, outdoor curtain hanging could become a simple, low-cost method for residents to reduce indoor temperatures, potentially easing pressure on cooling systems and improving comfort. The initiative also underscores the need for future building standards to consider climate resilience across a broader temperature spectrum, not just winter conditions.

Climate Change and Building Design Challenges in Amsterdam
Amsterdam’s building regulations have historically prioritized insulation for winter, given the city’s cold climate. However, recent years have seen a rise in extreme weather events, including heatwaves reaching record highs. The current heatwave, with temperatures hitting approximately 40°C, is testing the limits of existing infrastructure and prompting new adaptive measures.
Previous studies have shown that buildings insulated for winter can retain excessive heat during summer, leading to discomfort and increased energy use for cooling. In response, the city has begun exploring innovative solutions, such as outdoor shading and ventilation strategies, to improve thermal comfort without heavy reliance on air conditioning.
This initiative to hang curtains outside is part of a broader effort to gather practical data on low-cost interventions that can be adopted by residents and policymakers alike.
“We are testing simple measures like hanging curtains outside to see how they can help residents stay cooler during this unprecedented heatwave.”

Effectiveness and Long-Term Impact of Outdoor Curtains
It remains unclear how effective hanging curtains outside will be in significantly reducing indoor temperatures over the long term. The practice is currently a temporary measure, and there is limited scientific data on its efficacy during prolonged heatwaves. It is also uncertain whether this approach can be integrated into standard building adaptation strategies or if it will be adopted widely beyond the current event.

Monitoring Results and Future Urban Heat Strategies
The city plans to monitor residents’ experiences and collect temperature data during the heatwave to assess the impact of outdoor curtains. If successful, authorities may recommend or incorporate similar low-cost shading solutions into broader urban heat management policies. Further research will explore the potential for integrating such measures into building codes and climate resilience planning.

Key Questions
Why is Amsterdam recommending hanging curtains outside during a heatwave?
The city believes that outdoor curtains can provide shade, reduce indoor heat, and help residents stay cooler during extreme temperatures, especially in homes built mainly for winter insulation.
Is hanging curtains outside a proven method to reduce indoor temperatures?
Currently, this is an experimental measure. While some experts suggest it can help, there is limited scientific evidence on its long-term effectiveness during heatwaves.
Should residents rely solely on this method for cooling?
No. Residents should use multiple cooling strategies and follow official advice. Hanging curtains outside is a temporary measure to gather data and test its potential benefits.
Will this practice become part of official building standards?
It is too early to say. If data shows positive results, authorities might consider broader recommendations or incorporate shading strategies into future building policies.
What other measures is Amsterdam taking to combat the heat?
The city is also exploring increased green spaces, water features, and cooling centers to help residents cope with rising temperatures.
