Energy3D

Energy3D is a compact CAD utility designed to help users create 3D buildings in a clean and intuitive working environment.

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.

You can copy it on any USB flash drive or other devices, and take it with you whenever you need to design buildings on the fly, without having to go through installation steps.

This is Java-based utility, so you should make sure you have previously installed the working environment on the computer, otherwise you cannot run the utility.

Energy3D gives you the possibility to draw platforms, walls, doors, windows, floors, and pyramid, hip, or custom roofs, convert the current roof to a gable one, and reveal or hide shadows and heliodons.

You are allowed to opt for an animated sun motion display, generate solar radiation maps, as well as set up the dedicated parameters related to energy analysis, namely time and location, temperature, energy values, and overall heat transfer coefficient for walls, doors, windows, and roofs.

What’s more, you can undo or redo your actions, show or hide annotations, zoom in or out, enable the interactive mode for previewing the building rotated to different angles, resize the house, as well as preview the printable parts from your drawing.

Last but not least, you can print the generated images or save them to PNG file format, manually rotate the buildings to different angles in the 3D environment using the mouse, select the unit of measurement, and pick the colors for the door, roof, floor, window, and platform.

During our testing we have noticed that Energy3D provides very good image quality, carries out a task very quickly, and no errors showed up throughout the entire process. However, just like any similar Java programs, it eats up CPU and memory, so the overall performance of the computer may be hampered.

Energy3D proves to be a reliable application that gives you a hand when it comes to designing buildings in a 3D environment.
