Used by sustainable design experts around the globe IESVE is a fast, accurate, sub-hourly, thermal simulation suite that can model new and existing buildings of any size and complexity. For architects, engineers and contractors, the platform allows cross-team collaboration from concept design to operation. Its power embeds energy and performance assessment across the entire building lifecycle. Integrate Performance Analysis into the heart of the design process.
Integrated suite of applications for accurate, sub hourly, thermal simulation for buildings of any size and complexity.
Quick and easy loads calculations and equipment sizing from the earliest stages of design.
Interoperability with BIM platforms enabling two-way information exchange to speed up the design process and facilitate digital design.
Move up to the best in loads analysis. From optimizing room and zone loads to detailed HVAC system and equipment sizing, IESVE offers the most practical, efficient, and accurate tools available.
Building energy modeling predicts building energy consumption, CO2 emissions, peak demands, energy cost and renewable energy production. Graphic-rich reports of building energy modeling metrics and reporting to AIA 2030 is automated.
Daylighting for LEED and BREEAM, electric lighting design, glare prediction, daylight harvesting, daylight autonomy and user-specified visualizations.
IESVE is officially approved and accepted for building energy code compliance by the Florida Building Commission, California Energy Commission (Title 24) and for US States that allow building energy code compliance with IECC and ASHRAE 90.1.
The new NECB Workflow Navigator automatically generates the Canadian Reference Building, so demonstrating compliance in Canada couldn’t be easier.
Integrating Performance Analysis into the heart of the design process, IES offers an unrivalled interoperability with other CAD design and analysis tools. The smooth and robust two-way information exchange between IESVE and BIM platforms speeds up the design process and facilitates digital design.
See how leading design experts and high profile projects have benefited from using the IESVE software.
Focal Engineering used IESVE to provide whole building energy modeling of the Leaf for the purposes of building permit compliance and LEED certification.
Covering around 150,000 sqft, the zero-energy, zero-carbon building will be the largest to receive the International Living Future Institute’s (ILFI) Zero Energy Certification. It will also be one of the first buildings to be certified zero carbon by ILFI.
Arup used IESVE to provide energy modeling and sustainability consulting for this unique, high-performance housing complex in Honolulu, which is on track to achieve LEED Gold.
We use the IESVE software almost exclusively for energy modelling projects because of the ease of use in creating multi-zone models with complicated geometry and HVAC systems. We have modelled over 60 projects using the software in the past year, and we’ve found with LEED projects we often get very few, if any, LEED review comments, which saves us valuable time.
The ability to view results, for example, air temperatures with a video rendering in VistaPro is fantastic and particularly useful for validating and interrogating your results – you can see exactly what’s going on in each zone. That, for me, is one of the strongest points of IES.
The IESVE software is the most sophisticated software package for building energy simulations in the industry. It enabled us to effectively model the complex and dynamic features of the design, as well as helped us understand and comply with occupant comfort criteria that are critical in a naturally ventilated building.
We've worked with these high-profile manufacturers to incorporate their products into our software so you can now apply them directly to your model and evaluate the impact they will have on the performance of your building.
