Software

An excellent reference for Building Energy Software is the Building Energy Software Tools Directory.

But otherwise here are some of the simulation tools currently out there on the market that our members are using:

Sefaira allows architects to focus on performance from the beginning of their design process with software that provides them with real-time feedback for their building’s design. Find out more…

 

green building studio

Green Building Studio® energy-analysis software enables architects and designers to perform whole-building analysis, optimize energy consumption, and work toward carbon-neutral building designs earlier in the process. Cloud-based energy-efficiency software helps teams achieve sustainable building designs faster and more accurately with powerful energy- and carbon-analysis tools. Find out more…

agi

AGI32 is a program that performs numerical point-by-point calculations of incident direct or reflected light on any real surface or imaginary plane. Within this scope, it is used to predict or quantify the distribution of artificial or natural light in any environment. Find out more…

 

 

ANSYS CFX software is a high-performance, general purpose fluid dynamics program that has been applied to solve wide-ranging fluid flow problems for over 20 years. At the heart of ANSYS CFX is its advanced solver technology, the key to achieving reliable and accurate solutions quickly and robustly. The modern, highly parallelised solver is the foundation for an abundant choice of physical models to capture virtually any type of phenomena related to fluid flow. The solver and its many physical models are wrapped in a modern, intuitive, and flexible GUI and user environment, with extensive capabilities for customization and automation using session files, scripting and a powerful expression language. Find out more…


DesignBuilder is a software tool for assessing and creating building designs. It provides a range of environmental performance data such as: annual energy consumption, maximum summertime temperatures and HVAC component sizes. The software can be used effectively at any stage of the design process from the conceptual stage where you may want to try out some façade options on a single room, through to production. Find out more…

EnergyPlus is a building energy simulation program for modeling building heating, cooling, lighting, ventilating, and other energy flows. While it is based on the most popular features and capabilities of BLAST and DOE-2, it includes many innovative simulation capabilities such as time steps of less than an hour, modular systems and plant integrated with heat balance-based zone simulation, multizone air flow, thermal comfort, and photovoltaic systems.Find out more…

ies

The IES Virtual Envionment is a unique, integrated system for building performance assessment that brings productivity to every aspect of the building design. It operates from a single building model, bringing together all the design strands you need in one unified system.Find out more…

 

Radiance is a suite of programs for the analysis and visualization of lighting in design. Input files specify the scene geometry, materials, luminaires,time, date and sky conditions (for daylight calculations). Calculated values include spectral radiance (ie. luminance + color), irradiance (illuminance + color) and glare indices. Simulation results may be displayed as color images, numerical values and contour plots. The primary advantage of Radiance over simpler lighting calculation and rendering tools is that there are no limitations on the geometry or the materials that may be simulated. Radiance is used by architects and engineers to predict illumination, visual quality and appearance of innovative design spaces, and by researchers to evaluate new lighting and daylighting technologies. Find out more…


Tas is a suite of software products, which simulate the dynamic thermal performance of buildings and their systems. The main module is Tas Building Designer, which performs dynamic building simulation with integrated natural and forced airflow. It has 3D graphics based geometry input that includes a CAD link. Tas Systems is a HVAC systems/controls simulator, which may be directly coupled with the building simulator. It performs automatic airflow and plant sizing and total energy demand. The third module, Tas Ambiens, is a robust and simple to use 2D CFD package which produces a cross section of micro climate variation in a space. Find out more…
