    • The Psychrometric Chart is an interactive web tool on which you can project a range of comfort metrics as well as mapping weather data or room air. Depending on the .epw or .csv file entered, a cloud of points is generated on an hourly basis that represents the climate and the associated comfort. Users can test climate strategies, map metrics, and analyze seasonal comfort challenges with customizable overlays and dynamic features.

    • The Psychrometric Chart is an interactive web application developed for analyzing climate and thermal comfort data. By inputting weather files (.epw) or EnergyPlus calculation results (.csv), users can generate a cloud of hourly data points that visualize temperature, humidity, and associated comfort levels. The tool allows users to test climate strategies, evaluate indoor and outdoor conditions, and assess their impact on thermal comfort.

      Key features include customizable overlays, such as the Givoni Bioclimatic Chart and ASHRAE Standard 55 comfort zones, enabling dynamic exploration of comfort metrics like Heat Index and Predicted Mean Vote (PMV). Users can seamlessly switch between absolute and relative humidity charts to better understand psychrometric processes. The tool supports data filtering by time range, allowing for seasonal or monthly analysis of climate challenges and potential solutions.

      Users can add process lines, map various metrics, and export data in JSON or CSV formats. With features like date range selectors, custom grid overlays, and the ability to visualize metrics such as solar radiation or HVAC performance, the Psychrometric Chart is invaluable for architects and designers aiming to create climate-responsive, comfortable building designs.
