The new urban climate model PALM-4U will allow municipal staff and city planners to simulate the effects of their planned construction projects on the urban climate so that they can gauge the consequences of extreme weather events before they happen, improve quality of life in urban areas and protect the health of the sick and the elderly. Researchers at the <a href=\"https:\/\/www.ibp.fraunhofer.de\/en.html\">Fraunhofer Institute for Building Physics IBP<\/a> created the user interface for the simulator, putting their many years of expertise in fields such as hygrothermics and indoor climate to good use.<\/p>\n\n\n\n<div class=\"io-block io-block__summary\"><ul><li>Fraunhofer researchers developed a simulation model to understand the tipping points that could lead to a climate collapse.<\/li><li>The model combines complex Earth system processes like sea ice melt, permafrost thaw, and monsoon dynamics.<\/li><li>It allows testing intervention strategies to prevent crossing catastrophic tipping points that would accelerate climate change.<\/li><\/ul><\/div>\n\n\n\n<p>Climate change challenges us all, and city planners are no exception. Researchers expect the incidence of prolonged hot spells, heavy rain, and storms to increase. \u201cDensely populated urban areas are particularly susceptible to extreme weather events, and they do more than just affect people\u2019s well-being. For individuals that are weaker or experiencing poor health, e.g., people in retirement homes, daycare centers, and hospitals, extreme weather events can be dangerous,\u201d explains Matthias Winkler, a hygrothermics expert at Fraunhofer IBP. This is why cities and municipalities are working intensively on planning construction initiatives that could help mitigate the consequences of climate change and make city climates manageable to a certain extent, thus maintaining and improving the quality of life in urban areas.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/archive.ioplus.nl\/wp-content\/uploads\/2023\/08\/ibp-simulationsmodell-gegen-den-klimakollaps-bild-2-1004x802.jpg\" alt=\"\" class=\"wp-image-454626\"\/><figcaption class=\"wp-element-caption\">The operating interface PALM-4U GUI allows municipal and planning office staff to apply the model in their practical work.<\/figcaption><\/figure>\n\n\n\n<p>The PALM-4U urban climate model allows users to depict and simulate how construction projects impact the urban climate, which makes it a valuable resource for planning offices and municipalities. It could be used to simulate greening a facade or planting trees, for example, to determine whether these measures improve the citizens\u2019 thermal comfort levels. The urban climate simulator also makes it possible to identify spaces particularly severely affected by high temperatures and model the impact that construction projects such as installing green spaces or unsealing surfaces would have on the climate in the surrounding areas before implementing them. Mr. Winkler and his team contributed to the complex tool by developing the PALM-4U GUI. This user interface has a straightforward, logical structure, allowing users to configure all the necessary functions and parameters.<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link\"><a href=\"https:\/\/innovationorigins.com\/en\/europe-sighs-under-heat-how-can-cities-arm-themselves-against-this-enemy\/\" class=\"vlp-link\" title=\"Europe sighs under heat.

This could also allow planners to assess whether investing in a particular building project would ultimately be profitable or whether another initiative might have the same effect at a cheaper price.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/archive.ioplus.nl\/wp-content\/uploads\/2023\/08\/ibp-a-simulation-model-to-counter-the-climate-collapse-906x1004.jpg\" alt=\"\" class=\"wp-image-454625\"\/><figcaption class=\"wp-element-caption\">Fraunhofer&#8217;s PALM-4U urban climate model analyzes the impact that urban development projects have on the local climate. This analysis can be scaled from the individual building or city neighborhood level up to entire cities.<\/figcaption><\/figure>\n\n\n\n<p>This tool&#8217;s data basis comprises meteorological data from sources such as the German weather service (Deutscher Wetterdienst, DWD) and regional climate models. Municipalities can also incorporate weather data\u00a0\u2014 such as temperature, humidity, wind speed, and even the level of fine particulate matter in specific squares in the city\u00a0\u2014 from any regional measurement stations they may have. In addition, the data basis will contain extensive geodata and city maps that show streets, squares, houses, bodies of water and green spaces. The more detailed and accurate the depiction of these elements is, the more reliable the PALM-4U simulation will be.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Thermal comfort, wind comfort, and pollution levels<\/h2>\n\n\n\n<p>Urban climate analyses tend to focus on three groups of topics, beginning with thermal comfort and cold air flows at night. This topic includes the thermal load in buildings, squares and streets caused by high-pressure weather conditions and whether there are enough ventilation corridors to aerate the region overnight. For the second topic, wind comfort, areas with different wind comfort criteria are identified based on the simulations and local wind statistics. This information can help draw conclusions regarding potential uses for the spaces in question, such as outdoor catering. The third topic involves analyzing the airborne fine particulate matter from sources such as domestic fires and automotive traffic, provided the available data.<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link\"><a href=\"https:\/\/innovationorigins.com\/en\/extreme-urban-heat-these-innovations-help-us-out\/\" class=\"vlp-link\" title=\"Extreme urban heat?

What can we do to keep the heat bearable?<\/div><\/div><\/div>\n\n\n<p>Where needed, the PALM-4U GUI offers an expert mode in which users can add further simulations based on their specifications. \u201cThe tool is scalable and can model the climate of an entire city or an individual neighborhood, district, or square,\u201d explains Mr. Winkler. To give just one of many possible examples, municipal staff and city planning offices can use the tool to test the effects of a high-rise on the building next door, the surrounding streets, or the entire district.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comparing different planning variants<\/h2>\n\n\n\n<p>The system comes pre-programmed with typical meteorological conditions suitable for simulating individual problems; the users can adjust these conditions to suit their own local specifications. For example, when studying thermal comfort, users can apply a model of summertime high-pressure weather conditions.<\/p>\n\n\n\n<p>\u201cWith PALM-4U, we can also compare different planning variants with each other. This means we can avert typical planning errors early on, which would otherwise result in situations where children at a poorly designed playground would be exposed to high levels of heat, for example,\u201d explains Sabine Giglmeier, a business development manager in the Hygrothermics section at Fraunhofer IBP. The simulator could also work out tricky climate issues from as early as the planning phase when constructing an extension for a retirement home or hospital, for example.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Support and advice for municipalities<\/h2>\n\n\n\n<p>The simulation results can be analyzed and displayed via the user interface. When developing the user interface, the Fraunhofer IBP researchers incorporated feedback from experts working in practical fields. \u201cWe collaborated with municipal staff from cities like Berlin, Stuttgart, and Dresden to gain a deeper understanding of their specific requirements and to optimize the system\u2019s suitability for practical application,\u201d says Mr. Winkler. The software is cloud-based, meaning there is no need to go through the expensive installation process and integrate it into existing IT systems.<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link\"><a href=\"https:\/\/innovationorigins.com\/en\/how-digital-twins-can-help-turning-an-urban-oven-into-an-oasis\/\" class=\"vlp-link\" title=\"How digital twins can help turning an urban oven into an oasis\" rel=\"nofollow\" target=\"_blank\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><img decoding=\"async\" src=\"https:\/\/innovationorigins.com\/app\/uploads\/2023\/08\/Bremen.jpg\" style=\"max-width: 150px; max-height: 150px\" \/><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">How digital twins can help turning an urban oven into an oasis<\/div><div class=\"vlp-block-1 vlp-link-summary\">Extreme heatwaves are affecting many European cities.
