Cities face growing pressure to respond to extreme heat, but choosing the right solutions is not always straightforward. Urban environments are complex, and measures that work well in one location may not perform the same way in another. This makes testing and validation a crucial first step before investing in long-term interventions.
That is why the Be Ready project focused not on quick fixes, but on testing and validating solutions before scaling them up.
A Test-First Approach to Urban Cooling
Rather than making large, expensive changes right away, Be Ready followed a simple idea: test small interventions, measure their impact, and learn from real results. This approach allowed cities to understand what works best in their own local conditions.
The project tested urban acupuncture measures—small, targeted actions placed in the hottest areas of the city. These included:
• Green solutions, such as trees and plants, to provide shade and natural cooling
• Blue solutions, using water to cool the surrounding air
• White solutions, including light or reflective surfaces that reduce heat absorption
Each measure was tested alone or in combination, depending on the characteristics and needs of the site.
Why Validation Is Essential?
The pilot was carried out in ten partner cities, each with different climates, urban forms, and user needs. Testing on a small scale made it possible to:
• Verify whether the solutions actually reduced temperatures
• Compare different types of measures and combinations
• Improve designs based on real performance, not assumptions
• Identify limitations or risks before making larger investments
• Collect feedback from residents and city stakeholders who used the spaces
This validation process helped cities avoid costly mistakes and ensured that decisions were based on evidence.
What Did We Learn?
The pilot showed that small, well-placed actions can make a real difference. Using temperature data, observations, and feedback from users and city stakeholders, the project gathered clear evidence about what works and what can be improved.
Key Recommendations
Building on the results of the pilot phase, the Be Ready project highlights several key recommendations for future action.
• Align cooling pilots with local and national climate strategies.
• Use shared indicators (temperature, humidity, biodiversity, user satisfaction).
• Replicate validated urban acupuncture measures in similar hot spots.
• Increase visibility through clear communication and digital storytelling.
• Engage communities and schools for long-term care.
• Combine cooling measures with public art to boost public support.
Looking Ahead
By testing first and scaling up later, cities can make smarter choices. The Be Ready pilot helps cities move forward with confidence—creating cooler, healthier, and more comfortable urban spaces for everyone.

Hot summers are becoming the new normal. Streets that once offered relief now store heat, nights stay uncomfortably warm, and heatwaves increasingly affect our health, daily routines, and public spaces. Cities are warming faster than their surroundings, creating so-called Urban Heat Islands—and this is a challenge that touches everyone.
The Be Ready Strategic Framework is about turning this problem into an opportunity. It helps cities plan smarter, long-term ways to stay cool and livable as the climate changes. Instead of quick fixes, it looks ahead—showing how cities can reduce heat risks while making neighborhoods healthier, greener, and more enjoyable.
At the heart of the framework are simple but helpful ideas: more trees and green spaces, cooler building materials, shaded streets, and public places designed for people, not just traffic. These nature-based and climate-sensitive solutions don’t just lower temperatures—they improve air quality, support wellbeing, and make cities nicer places to live.
Importantly, the framework provides common recommendations for the entire Danube Region, creating a shared foundation for action and cooperation. It serves as a Danube-wide UHI resilience plan, promoting nature-based solutions, climate-sensitive urban design, and resilient public spaces that deliver environmental, social, and health benefits.
Designed as a flexible and transferable tool, the Be Ready Strategic Framework helps local and regional authorities turn EU climate objectives into concrete action, strengthen cross-border cooperation, and build cooler, healthier, and more resilient cities for the future.
Being “Be Ready” means preparing cities not just to survive hotter summers—but to thrive in them, creating cooler, healthier, and more resilient places for everyone.

Cities are heating up, and heatwaves are becoming more common. Concrete, asphalt, and buildings trap the sun’s heat, making urban areas warmer than the surrounding rural areas. This “Urban Heat Island” effect can impact our comfort, health, and daily life.
The Be Ready Virtual Pilot-based Training Program is a free, online course created to help people understand this challenge and learn how cities can respond to it. Developed by universities and experts working with European cities, the course turns real-life experience into practical learning that anyone can follow.
The training includes three short online modules. Together, they explain what Urban Heat Islands are, how cities can identify areas most affected by heat, why involving local communities matters, and how small, targeted actions—such as adding greenery or improving public spaces—can help cool cities.
The course is online, free of charge, and self-paced, so learners can join anytime and study at their own speed. It is available on the Canvas learning platform in English and 11 other languages, and no specialist knowledge is needed.
The Be Ready Virtual Pilot-based Training Program is open to everyone interested in climate-friendly cities—from local authority staff and urban planners to students, researchers, and citizens. It offers a simple and practical way to learn how cities can become cooler, healthier, and better prepared for hotter summers.

Discover the New Booklet: “Acupuncture for Healthy and Heat-Resilient Communities”
Cities are becoming increasingly hot, with heatwaves turning into a regular part of daily life. Urban surfaces such as streets, buildings, and paved areas absorb heat and release it slowly, causing cities to be warmer than their surroundings. This phenomenon, known as the Urban Heat Island effect, impacts people’s health, comfort, and overall wellbeing.
A new digital booklet is now available for anyone interested in making cities cooler and healthier. Titled “Acupuncture for Healthy and Heat-Resilient Communities,” it shares the results and lessons of the Be Ready project, which tackles urban heat islands—areas in cities that can be several degrees hotter than surrounding rural areas.
What makes the booklet special is its focus on practical, easy-to-apply solutions. Instead of large-scale urban redesigns, it highlights “urban acupuncture”—small, targeted actions that have a big impact. The booklet shows how cities can use:
Green acupuncture – planting trees and greenery to lower temperaturesWhite acupuncture – using reflective materials to keep surfaces coolBlue acupuncture – smart ways to use water to reduce heat
The booklet is full of real stories, step-by-step tips, and examples that other cities can replicate. It’s designed to be both inspirational and practical, helping urban planners, community leaders, and policymakers bring heat-resilient solutions to life.
It also links these measures to major European policies, like the European Green Deal and the EU Strategy on Adaptation to Climate Change, showing how small interventions can support broader climate goals.
Available in English and free to access, this booklet is a go-to guide for anyone looking to create cooler, greener, and more resilient cities.

Discover how a once-neglected urban courtyard in Sofia’s Draz Mahala neighbourhood has been transformed into a vibrant urban climate shelter – a place that cools, connects and strengthens the community.
This inspiring pilot action, brought to life under the Be Ready project, illustrates how small strategic interventions can make cities more resilient to urban heat islands — a growing challenge across the Danube region. Situated near Lion’s Bridge, one of Sofia’s busiest and most heat-exposed areas, the 350 m² site was redesigned through co-creation with local residents, artists, students, NGOs and migrants.
The video showcases every step of this transformation: from clearing the neglected space and installing shade structures with a water-misting system and drinking fountain, to planting climate-adapted greenery and creating community garden beds. Artistic installations and storytelling elements by young local creators add a unique cultural dimension to the shelter, turning it into a cool refuge, public meeting point and climate awareness hub.
Since its inauguration, the climate shelter has become a valued public amenity – offering relaxation, community activities, free health checks, games and opportunities to engage with nature. This pilot not only responds to heat stress in an urban hotspot but also validates the “urban acupuncture” approach — demonstrating how small, thoughtful interventions can have a big impact on neighbourhood well-being and resilience.

A neglected municipal courtyard in Sofia’s Draz Mahala neighborhood has been transformed into an urban climate shelter – a place that offers rest and coolness during the summer heat, while revitalizing one of the city’s more vulnerable areas. The pilot project by the Sofia Development Association, under the Be Ready project of the Interreg Danube Region Programme, co-funded by the EU, turned 350 square meters of unused municipal land into an attractive green space co-designed with local residents.
Located near Lion’s Bridge – one of the city’s busiest and most heat-exposed transport arteries – the climate shelter responds to a pressing urban challenge: the growing impact of urban heat islands. The area is home to a significant number of vulnerable citizens and disadvantaged groups, including elderly people, low-income households, and migrants.
The transformation began in May with a workshop that brought together residents, students, artists, NGO representatives, and migrants to shape a shared vision for the space and define its community needs. What followed was a dynamic collaboration that engaged over 130 citizens and the Sofia Development Association team in volunteer activities and artistic interventions.
Through joint effort, the site was cleaned up, all sealed surfaces were replaced with permeable ones, and a shaded relaxation area with a water mist cooling system was built. In a neighborhood where there is only one public drinking fountain per 50,000 residents, the installation of a new one is a major benefit. With expert guidance from the University of Forestry and ecologists from Serdika District, climate-resilient trees and plants were planted, along with a small community herb garden. The climate shelter also includes other ecological features such as composting, a rainwater collector, an insect hotel, and birdhouses.
Young artists and designers from Studio Vazel brought the space to life with visual art and installations that tell stories and engage visitors in environmental care.
The climate shelter has been warmly welcomed by local residents, offering a new space for relaxation, amenities such as blood pressure measurement, board games, opportunities to work in the herb garden, and to host small community events. The pilot project was carried out with the support of municipal councillors from the Sofia Development Association’s Board of Directors and the district administration, and was highly praised for its innovative approach, inclusive design, and effective use of municipal property for public benefit.
The project proved the feasibility of the urban acupuncture concept – creating small, smartly designed “pocket parks” that bring relief where large-scale investments are not possible.
