Energy3D is a free, simulation-based computer-aided design (CAD) tool developed by The Concord Consortium under National Science Foundation (NSF) funding. It allows users to design green buildings, solar energy systems, and renewable energy power stations, then immediately analyze their energy performance using built-in computational physics engines. Key Features
Concurrent Engineering & Design: Users sketch realistic structures directly onto imported satellite imagery via the Google Maps API. Performance metrics adapt instantly as elements change.
Physics-Based Simulations: The software generates detailed heat maps and data-logger-style graphs. It measures solar radiation, thermal insulation values (R-values), and heat loss or gain.
Global Weather Integration: It leverages real-world data from a typical meteorological year (TMY) across nearly 400 locations globally. This allows users to “transport” a building design to different climates to see how context alters energy consumption.
Solar System Design: Users can precisely drag and drop solar panel racks or mirrors. They can also adjust tilt angles, or test complex solar farms and tracking arrays.
Heliodon Simulator: An interactive sun tracker simulates 24-hour trajectories across seasons. This visualizes realistic shadows to optimize window and window-overhang placement.
From Digital to Physical: A “Blueprint Wizard” deconstructs 3D designs into printable 2D paper templates. Students can cut out and construct physically accurate scale models. Target Audience and Educational Impact YouTube·Innovation in Urban Science Education Lab Introduction to Energy 3D
