Step-by -step complete analysis workflows
A revolution in building performance analysis, VE-Gaia’s complete workflow environment is driven by “step-by-step” smart navigation that opens wide the power of IES analysis. A series of Navigators guide users through a range of tasks; from advanced modelling, to energy/carbon analysis, to LEED credit interrogation.
Analysis to understanding
Weaving a clear route through the analysis process, from modelling to reportage, users can easily undertake complex advanced simulations. Designers can track progress, control quality, iterate workflows, trigger simulations, filter results and produce automated visual and rich-text reports.
Increased productivity
Within a project users can easily mould and define the workflow within the framework provided by the Navigators. Any common component is always up to date and users can move between Navigators at any time, setting up rapid cycles of development by jumping back and forth.
Quality checks
VE-Gaia includes ‘notes’ and ‘date/user stamp’ functions that facilitate a direct quality assurance process which can be exported for documentation purposes.
Easy model import
Direct connectivity to SketchUp™, Revit® and ArchiCAD® allows quick, effective feedback direct from early and detailed architectural models. gbXML and DXF import functions are also offered, alongside the ability to input and manipulate exact building data within an integrated central data model.
Model Building
Interoperability and ease of connectivity between CAD/BIM modelling tools and analysis software breaks down many of the barriers to effective utilisation of analysis for green design, especially at the early design stages. If professionals can quickly and easily undertake analysis directly from design models then feedback fits with iterations, is more effective and can facilitate the multi-disciplinary decision making of an integrated design process.
Analysis models can be developed directly within IES’ software or can be bought in using a variety of tight connectivity and import capabilities.

VE-Gaia Features
The baseline VE-Gaia includes the following Navigators, with the addition of more planned in future versions. Additional ‘add-on’ Navigator packages are also available to further enhance the functionality of VE-Gaia.
Model Geometry
Model import, setup, and creation workflow; including grouping rooms and assigning weather data.
Model Data
Detailed data assignment and manipulation workflow; including the consideration of building metrics, natural resources and material use. Understand the available potential for solar/wind energy and rainwater resources, the dominant heat exchange characteristics and other metrics of the building and a headline summary of materials used.
Climate
Climate exploration, analysis and review; including consideration of future climate predictions. Draw the relevant characteristics related to impact of climate on potential efficiency measures to the surface for evaluation, and understand with the IES Climate Index the potential the climate has to affect the amount of energy a building needs to achieve occupant comfort.
General output on ASHRAE/Koeppen-Geiger climate classification, temperature, moisture/humidity, wind, precipitation, solar energy, diurnal swing and Mahoney comfort stress analysis. IES Climate Energy Index output includes global comparison and breakdown of potential energy types.
Water
Workflow reviewing water availability, appliance water use and reduction potential. Understanding water availability, allows suitable reduction targets to be set, while consumption predictions and assessment of potential for efficiencies, and rainwater/greywater/blackwater use gives rapid insight into the impact of potential strategies. Occupancy and fixture type selections can be set to establish a baseline, and a proposed design; reduction measures can be defined and reviewed for potential impact of water use reduction. LEED, BREEAM and Green Star calculation approaches are offered.
Navigator for Sustainability
A collection of sustainability analysis workflows; covering energy/carbon, simulation, heating/cooling loads, daylighting, solar shading, renewable/low carbon technologies, occupant comfort and material usage.
Energy/Carbon Simulation
Interrogate a range of energy and carbon metrics without shading, with simple external shading, or with advanced solar penetration – using a dynamic thermal simulation at sub-hourly time-steps. Including whole-building annual energy/carbon results, energy breakdown by end use, monthly carbon emissions, benchmark against Architecture 2030 Challenge, max/min results for temperature, humidity and comfort at a room level, and a per room peak loads breakdown based on dynamic simulation.
