See how IBAK Hamburg used IESVE to model, optimise, and validate performance for PRIMUS Developments GmbH, for the multi-award winning project in Offenbach am Main, Germany - achieving DGNB GOLD (68.8%).

These requirements were met through:
🌡️Dynamic thermal modelling for extreme climate scenarios using TRYs
💡 Future-ready performance testing (2030 & 2050 climate scenarios)
☀️Daylight & visual comfort analysis (models for DF + UDI)
📊 Streamlined reporting workflows with Tableau integration

A powerful example of how integrated simulation supports compliance, clarity, and client confidence.

🏗️ We're at Digital Construction Week this week - and if you're heading to the Excel London, don't miss this one.

Colin Rees, Co-Head of Consultancy at IES, is taking to the Net Zero Stage this Wednesday to tackle one of the most pressing challenges in data centre design right now.

AI is pushing data centre rack densities up to 1MW, doubling global energy consumption and breaking the assumptions that traditional design methods were built on.

Colin's session will cover how physics-based dynamic simulation and Digital Twins are changing what's possible - including a hyperscale case study that achieved 95% water reduction and a PUE of 1.16.

📅 Wednesday 3rd June | 11:30–12:00
📍 Net Zero Stage | Excel London

If data centre sustainability is on your radar, this is worth 30 minutes of your time.

🌎 One week to go - LEED v5 Explained: What Energy Modelling Teams Need to Know

LEED v5 raises the bar on performance — and energy modelling now plays a critical role in demonstrating compliance. If your team already works with LEED v4.1, the challenge has shifted from whether to model to how to use modelling evidence strategically to inform decisions, document outcomes, and reduce submission risk.

🎤 Join @ Tristan Truyens of IES and Carrizo of for a free live webinar focused on what LEED v5 means in practice for energy modelling teams working across North America.

✅ Key differences between LEED v4.1 and LEED v5
✅ Which LEED v5 credits rely on modelling — and what data is required
✅ Real-world project achieving LEED v4 Gold, with maximum energy points using IESVE

📅 Thursday, June 4 | 3pm EDT
👉 Register now to stay ahead of LEED v5 and strengthen your project strategy

📖Learn how to start building a reusable library of custom HVAC systems in IESVE.

If you’re building systems from scratch or working with HVAC files shared by colleagues, knowing how to save and reuse them efficiently can help streamline future modelling work.

🎥 In this video, Bhandari shows you how to add a custom HVAC system to a local HVAC library for easy access.

⚙️ This simple workflow can help improve consistency, save time, and make repeat project setup easier.

⚡ The Biggest Risks in Data Centre Delivery ⚡

With global data centre energy demand set to double to around 945 TWh by 2030, and grid connection delays stretching 7–10+ years across Europe, the pressure to de-risk projects has never been higher. Planning uncertainty, grid constraints, and environmental approvals are now stalling or derailing projects before construction even begins.

Dynamic, whole-facility simulation provides the clarity needed to turn uncertainty into actionable insight across planning, design and operation:
✅ Test energy, cooling & design strategies before build
✅ Evidence real-world performance under real climate conditions
✅ De-risk planning approvals and grid connection strategies
✅ Make faster, more informed investment decisions

💡 We’ve answered the top 10 questions from engineers worldwide.

As energy standards tighten, accurately modelling thermal bridging is no longer optional. It’s essential for compliance, performance and design confidence.
We’ve answered the top 10 questions from our recent webinar in this expert Q&A.

✅ Psi & Chi values — where do they come from?
✅ Avoiding double counting
✅ Compliance with Part L, SBEM, ASHRAE & more
✅ Using results beyond energy modelling

The shift is clear: it’s no longer if thermal bridging matter - it’s how well you model it.

Data centres are on course to consume a tenth of the world's power by 2050, and the pressure on the UK grid is already being felt.

IES' Colin Rees features in today's City AM piece on the growing tension between AI infrastructure demand and clean energy targets, making the case for transparency and independent verification of data centre carbon and energy claims.

If you're thinking about how to approach data centre energy performance and carbon reporting, this is a conversation worth having.

Colin and Richard Tibenham are at Data Centre LIVE in London this week - if you'd like to connect and arrange time with them, drop a comment below or send a direct message.
