| + | |||
| + | == Highlights == | ||
| + | * **Huge simulation performance improvements.** Simulations run **up to 10x faster** now. | ||
| + | * **General overhaul of all applications.** Overall user workflow improvements and loading time decreases, for example in Spaces. | ||
| + | * **Fast Thermal Comfort (Hourly or as Statistics).** Quick estimations for pedestrian-level thermal-comfort results: Hourly UTCI values without a full simulation, plus a statistics module that aggregates UTCI thermal-stress over longer periods of months, seasons or year-long. ** EXCLUSIVE TO BUSINESS LICENSE TIER** | ||
| + | * **Wind Comfort:** Assess pedestrian wind comfort directly in ENVI-met, with multi-directional analysis, exceedance probabilities and grades against recognised standards (NEN 8100, Lawson, Davenport). ** EXCLUSIVE TO BUSINESS LICENSE TIER** | ||
| + | * **Surrounding-area presets:** Characterise the urban context upstream of your model with ready-made urban-climate-zone and land-cover presets, from open water and countryside through to dense city cores. | ||
| + | * **Absolute air temperature is now the primary temperature output**, with air pressure referenced to the actual site elevation rather than a fixed standard value. Potential temperature remains available in the result files. | ||
| + | * **Building indoor climate & air-conditioning heat:** Give individual buildings a controlled indoor temperature and decide whether their air-conditioning heat is rejected into the outdoor air, so the urban heat that air conditioning actually creates shows up in your results. Or allow automatic ventilation of buildings, so that building indoor temperatures are regulated based on outdoor and indoor conditions. | ||
| + | * **Spin-up of the model:** ENVI-met now runs a spin-up phase for soils, materials etc. that automatically derives their initial temperatures, | ||
| + | * **Smaller, standardized project files:** Model area and database files now use a modern JSON format that is more compact, easier to manage and readable/ | ||
| + | * **Simpler project setup:** The scenario system has been retired, with automatic migration of existing projects. Along with the removal of the scenario system, ENVICentral and Monde apps were discontinued and removed from the software suite to improve clarity in the workflow. The reporting feature of ENVICentral now lives in Leonardo. | ||
| + | |||
| + | == ENVI-core == | ||
| + | **Major Changes** | ||
| + | * **Faster, more robust simulations: | ||
| + | * **Fast Thermal Comfort & statistics: | ||
| + | * **Wind Comfort:** Multi-direction wind-field analysis with exceedance probabilities, | ||
| + | * **Surrounding-area presets:** Characterise the urban context upstream for each model domain border with ready-made urban-climate-zone and land-cover presets, from open water and countryside through to dense city cores. | ||
| + | * **Absolute air temperature** is now the primary temperature in result files, listed ahead of potential temperature, | ||
| + | * **Building indoor climate & air-conditioning heat:** Set an indoor temperature per building and choose whether the heat its air conditioning removes is released into the surrounding air, letting you study the outdoor warming that cooling demand produces. Allow natural ventilation of buildings based on thermal indoor/ | ||
| + | * **Spin-up of the model:** ENVI-met now runs a spin-up phase for soils, materials etc. that automatically derives their initial temperatures, | ||
| + | * **Extended atmospheric inflow column:** The vertical profile that feeds the model is now computed as a full 1-D atmospheric column reaching 4 km, explicitly representing night-time inversions, the residual layer, large-scale sinking motion and the Earth' | ||
| + | * **New output variables: | ||
| + | |||
| + | **Minor Changes** | ||
| + | * Improved longwave radiation physics, including carbon dioxide as a separate absorbing gas — and a markedly faster radiation calculation at the same time. | ||
| + | * The new Surrounding Area settings also include the radiative effect of the surroundings (shading and longwave emission from the virtual skyline). | ||
| + | * Improved numerical stability across turbulence, radiation and pollutant calculations, | ||
| + | * Faster radiation and shading calculations, | ||
| + | * Faster and more stable CO2 dispersion. | ||
| + | * Option to force background pollutant concentrations for sensitivity studies. | ||
| + | * Refinements to surface temperature, | ||
| + | |||
| + | == ENVI-guide == | ||
| + | **Major Changes** | ||
| + | * **Set up Fast Thermal Comfort studies:** Choose your datetime and configure the new modules in a few clicks. ** EXCLUSIVE TO BUSINESS LICENSE TIER** | ||
| + | * **Redesigned simulation-type selection: | ||
| + | * **Removal of legacy advanced settings** that are now handled automatically by the model. | ||
| + | * **Added building options** regarding handling of air conditioning, | ||
| + | * **Soil temperature settings removed**, as initial soil temperatures are now derived automatically during spin-up. | ||
| + | **Minor Changes** | ||
| + | * More reliable restoring of output folders and project settings when loading projects. | ||
| + | * FOX weather file generation from the Rhino plugin (run as a background task of ENVI-guide) is fully supported. | ||
| + | |||
| + | == Spaces == | ||
| + | **Major Changes** | ||
| + | * **Surrounding Area:** A modern replacement for the nesting-grids system. Describe the urban surroundings of your model for each border with urban structure presets, from open water to extremely dense urban. Surrounding areas of existing models will default to the compact mid-rise class. | ||
| + | * **Air Conditioning: | ||
| + | * **Noticeably smoother editing and navigation** in large 3D models. | ||
| + | **Minor Changes** | ||
| + | * The 3D building editor now handles tall structures in full. | ||
| + | * A clearer plant preview that always shows the 3D-plant' | ||
| + | * A range of stability and rendering fixes for a more dependable editing experience. | ||
| + | |||
| + | == Albero == | ||
| + | **Major Changes** | ||
| + | * **More detailed tree parameters** regarding photosynthesis rates can be selected and modified. | ||
| + | **Minor Changes** | ||
| + | * Mean leaf-area information is now shown in the parameter overview. | ||
| + | * A robustness and performance pass for smoother sliders, faster filtering and a more stable 3D view. | ||
| + | * Input validation and crash-safety improvements across the plant-editing tools. | ||
| + | * Plant scaling is now saved reliably — scaled plants keep their dimensions after you restart the app. | ||
| + | |||
| + | == BIO-met == | ||
| + | **Major Changes** | ||
| + | * **Faster handling of large datasets:** Improved data handling (including NetCDF) with quick access reading for much faster processing of large files. | ||
| + | **Minor Changes** | ||
| + | * Personal parameters (age, gender, clothing, activity) are now fully integrated into dynamic comfort along movement routes, with an improved Dynamic Comfort interface. | ||
| + | * Comfort indices now use absolute air temperature, | ||
| + | * On complex terrain, all comfort indices now consistently sample the meteorological fields at a fixed height above the local ground surface. | ||
| + | * Hardened comfort calculations (PET / PMV safety caps) and more robust person-position handling. | ||
| + | * Refinements to the PET calculation module. | ||
| + | |||
| + | == Leonardo == | ||
| + | **Major Changes** | ||
| + | * **Open NetCDF files directly** alongside the familiar EDX/EDT format — including files that combine atmosphere and façade data — with no conversion step. | ||
| + | * **Reporting feature now lives in Leonardo**, making it the one place for analysis, visualization and reporting processes after ENVIcentral has now been retired. | ||
| + | **Minor Changes** | ||
| + | * The legacy EDX-to-NetCDF converter has been retired, as NetCDF has been written by default in every simulation in recent versions. | ||
| + | * Faster data extraction and 3D navigations thanks to better value caching. | ||
| + | * A new one-click option to put two maps on a common, automatically scaled legend so they can be compared directly. | ||
| + | * Inverted color palettes now display as expected. | ||
| + | |||
| + | == DBmanager == | ||
| + | **Major Changes** | ||
| + | * **JSON databases: | ||
| + | **Minor Changes** | ||
| + | * Improved support for regional number formats and language settings. | ||
| + | * New validation for air gap and soil properties, so invalid material definitions are caught as you enter them rather than during a simulation. | ||
| + | * Fixes to clipboard handling, data export and dialog validation. | ||
| + | |||
| + | == A Refreshed Materials & Plants Database == | ||
| + | * ENVI-met 6.0 ships with a cleaned-up and modernised materials and plants library: outdated entries have been removed, soil and material properties updated, and tree definitions revised to better match typical urban dimensions, giving you better, more consistent starting points for every project. Legacy items are removed to reduce loading times of all apps. **They are replaced by default items during simulation loading in the ENVIcore, if not replaced by the user beforehand** | ||

| + | |||
| + | ENVI-met is subject to continuous substantial model development. Simulations run in a version may therefore differ from those run with earlier versions, as is normal for any major release of a physical model. Results from earlier versions remain valid as documented outputs of the model version used. For comparisons between scenarios, we recommend running all variants with the same version. | ||
