This enables the optimal integration of both tools within projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Engineers and building simulation specialist value the following advantages:<br><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heating Load and Cooling Load can be determined precisely in IDA ICE using dynamic building simulation<\/li>\n\n\n\n<li>For larger projects involving multiple generators or sources, such as hospitals, schools, residential developments, hotels and multi-family buildings, using Polysun to simulate the thermal energy system significantly reduces the time spent on design, while making the most of the strengths of both tools<\/li>\n\n\n\n<li>The wide range of energy system design configurations and scenarios in Polysun is appreciated by all stakeholders.<\/li>\n\n\n\n<li>Compliance documentation (e.g. BREEAM or LEED) can be reliably produced and detailed design variants can be developed<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The most influential design parameter, heating load and cooling load, is transferred directly between the two software solutions &#8211; IDA ICE and Polysun. The following FAQ article provides step-by-step guidance for project teams using both tools.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-in-which-format-can-files-be-imported-into-polysun\">In which format can files be imported into Polysun?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Polysun expects two separate profiles with hourly values: one for heating and one for cooling. These profiles can be imported either via a .CSV file or by copying and pasting in Excel. Importing takes place separately for each profile in the building component or the source\/sink component.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-1-open-building-model-and-run-simulation\">Step 1: Open building model and run simulation <\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Open your project in IDA ICE and ensure that the simulation has been fully calculated and completed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"966\" height=\"526\" src=\"https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary.png\" alt=\"\" class=\"wp-image-143661\" srcset=\"https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary.png 966w, https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary-300x163.png 300w, https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary-768x418.png 768w, https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary-200x109.png 200w, https:\/\/www.velasolaris.com\/wp-content\/uploads\/2026\/04\/IDA-ICE-Simulation-Summary-400x218.png 400w\" sizes=\"auto, (max-width: 966px) 100vw, 966px\" \/><figcaption class=\"wp-element-caption\">Source: Equa Getting started with IDA ICE<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-2-open-results-for-heating-and-cooling-demand\">Step 2: Open results for heating and cooling demand<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Click on Summary and select Heating or Cooling.
