Real-time design support, inside Revit.
Stop waiting for late consultant reports or wrestling with black-box engines. LU-NDT brings an AI consultant and transparent energy and daylight analysis directly into your architectural design process, tuned for Swedish building regulations. Join our pilot for a free two-week trial.
- Real-time
- feedback as you model
- Transparent
- building physics based
- Normative
- Swedish building regulation based

An educational tool for students, a time saver for professionals. Built to support energy-efficient building design
Have a look at LU-NDT
Data-driven decisions, from the very early stage.
LU-NDT is built for architectural and engineering firms that want to design energy-efficiently without slowing down — saving time, avoiding costly late-stage redesigns, and giving you a head start on regulatory compliance.
Real-time energy & daylight
Analysis runs as you model. See the consequences of your design decisions in seconds, not weeks.
Transparent, not black-box
Every input and intermediate result is visible — so you and your team can understand the numbers.
Swedish regulations
Built around the codes all architectural firms actually have to comply with in Sweden. BBR, Sveby standardized input data, and the ISO 52016-1 calculation method.
AI-powered consultant
LU-NDT's built-in AI agent pinpoints which building element is causing a performance failure — and how to fix it — instead of generic energy efficiency tips, supporting the entire design process.
Be among the first to explore LU-NDT.
We're inviting a small group of architectural practices to join our trial. Leave your details and we'll send you the installation package — two weeks of free access, no subscription required.

The people behind LU-NDT
LU-NDT began as a PhD research project at Lund University, focused on ICT support for energy-efficient building design. Developed with backing from Lund University and support from LU Innovation, the project has evolved from an academic research initiative into a practical solution for the building industry.

Pouria Elahi
Technical Lead
PhD student, Energy and Building Design, LTH
Energy and building design PhD researcher with a background in Building and Structural Engineering. Focuses on ICT-support for energy-efficient design, building simulation, and energy analysis at Lund University.

Maria Karamitsiou
Commercialization Lead
MSc student in Energy-efficient Building Design, LTH
Architect and sustainability consultant with experience across concept design, permitting, and construction supervision. Specialises in building performance simulation, sustainable retrofit design, and BIM modelling.
This summer, that transition took a big step forward: LU-NDT joined Leapfrogs, the summer accelerator for student ventures at X-Lab, alongside more than twenty other student teams from Lund University, Blekinge Institute of Technology, and Kristianstad University. It's the story of how research gets applied, tested, and shaped into something the industry can actually use.
LU-NDT is now taking its next step: moving from a two-person accelerator project into a growing team.
Help us build what's next
If you're a student or researcher who wants hands-on experience building a real product from the ground up, we'd love to hear from you — whatever stage you're at.
We're looking for people with backgrounds in:
AI & Machine Learning
Training and deploying models, applied ML engineering.
Software Engineering
Product, tooling.
Business & Commercialization
Go-to-market, partnerships, and growth.
Sustainability & Building Design
Energy performance, architecture, and building physics.
Simple, transparent plans.
Start free with the pilot plan, then scale as your team grows.
Pilot Study
First 2 weeks of full software access for selected Swedish architecture studios.
Get in touch
If your company works with buildings, energy or sustainability, we'd like to talk about working together.
