Our Product Vision

By 2030, we want to improve the performance of 10 million energy intensive buildings worldwide. This is how we get there — and how you can be part of it.

Built on a Foundation You Can Trust

For more than 30 years, we've kept investing in IES software - not as a one-off overhaul, but as continuous, deliberate development shaped by what customers actually need. Every update responds to real feedback, real projects, and real regulatory change, rather than chasing trends.

Our Product Vision sets out where that investment is taking us next: the foundations that stay constant, what we've delivered recently, what's coming in 2026/27, and how you can help shape what we build next.

Physics Based

Foundational physics principles underlying in our Apache simulation engine.

Compliance-Driven

Compliance driven tools that keep pace with a fast-moving global regulatory landscape.

From Design to Operation

One connected journey across the IES Ecosystem and the building lifecycle.

Recent Enhancements You May Have Missed

Every release builds on the last. Here's some of the new enhancement IESVE 2025 brought to your workflow.

Climate Assessment Report

The new Climate Assessment Report gives you a one-click assessment of a climate file within seconds, no model required. Clear, visual and interactive analysis makes it easy to evaluate and compare climate data.

Instant results from weather files - ASHRAE design day data, full 8760-hour analysis, solar/PV, and carbon factors in one report
Climate insight to guide early decisions on massing, orientation, and system sizing
Interactive graphics that make client conversations easier
Meets LEED v5's climate resilience requirement
Fits your existing workflow: climate → model → loads → HVAC design

Thermal Bridging

The new Thermal Bridging capability in the VE lets you model bridges using Psi and Chi values alongside existing methods - for higher-fidelity energy calculations and streamlined compliance with codes like NECB, ASHRAE 90.1, and UK Part L.

Psi/Chi and Y-value methods alongside existing composite layer calculations, so you can test what works best
Automatic identification of non-repeating linear bridges from geometry, with default data sets included
Quickly test design sensitivity to thermal bridging requirements and standards
Aggregate totals or drill into individual rooms and surfaces, with clear visuals for client conversations
Powered by enhancements to IES's APACHE engine for a true physics-based result

Parametric Simulation Enhancements

Enhancements to Parametric Simulation make early-stage and retrofit evaluations faster and more flexible — from single-variable studies to multi-parameter, whole-building analysis.

New Location and Envelope Template parameters test the same geometry across multiple locations and construction variants
Complete construction make-ups can be grouped and swapped in and out, cutting the number of permutations needed
New DHW and TEDI outputs add deeper insight, including Canadian energy code compliance support
Armstrong® Templok® Ultima PCM ceiling tile now integrated, for rapid testing of coverage, HVAC strategy, and control settings

What's coming in 2026/27?

A staged journey, not a single big-bang release. Here's where each workstream stands and what's next.

Faster HVAC Workflows

3D and the ASHRAE Heat Balance Method are now the benchmark for HVAC design. IESVE already delivers both; we're making the route to them shorter. A new Navigator lands first, simplifying navigation through VE, followed by a next-generation product evolution.
IES Live

Two years of real operational insight, delivered through our consulting team, are becoming a product. Next up: AI-driven recommendations powered by physics-based digital twin technology, opened up to trusted Beta partners and consultants to close the gap between design and operation.
Data Centre Modelling

Data centre demand keeps surging, and AI's own energy and water footprint makes this harder, not easier. We're your expert partner on DC projects today; 2026 brings enhanced ApacheHVAC capabilities for liquid and hybrid cooling and rack-level detail, ahead of a dedicated IES data centre solution.
IES Sync for Revit

The first step towards a connected IES ecosystem, built on a new shared intelligence layer that carries your geometry and energy-relevant data without rebuilding at each step. Phase 1 launches at Autodesk University in September 2026, joining up your Revit model with your IES workflow.

New Customer Feedback Programme

Our Product Vision is shaped by the people who use our software every day. By joining our Customer Feedback Programme, you'll become part of a community helping to shape the future of our products. Whether you're sharing your thoughts in a quick survey, taking part in a research conversation, or getting early access to new features, your feedback will play an important role in helping us build better solutions for everyone.
