We offer a premium, precision, streamlined service with no back-and-forth, no guesswork, and no delays. Just clear, certifiable results you can rely on.

We provide thermal bridge modelling for both building regulations compliance and Passivhaus certification. All work for building regulations compliance is carried out by an NSAI-approved Thermal Modeller.

You’re under pressure to deliver high-performance buildings—but thermal bridge modelling is too often a point of failure. Confusing and hard to follow reporting that is not ready for building regulations or Passivhaus certification, wasting your time and increasing costs.

At mosart, we do things differently. We’re not just thermal modellers. We’re Passivhaus Certifiers, Passivhaus Designers, building physics experts, and trusted partners to the largest developers in Ireland and the UK. We’ve delivered thermal bridge modelling for thousands of junctions across every major construction method know exactly what it takes deliver a hassle-free certification process.

No Back-and-Forth

We have developed a complete, easy-to-follow thermal data submission system. No endless and confusing emails looking for the necessary information. One handover, then we deliver.

Visual Report Outputs

Our Part L reports are designed for clarity and precision. You’ll receive clear, easy-to-follow results —enhanced with informative visuals and prominently highlighted Psi, Chi, and fRsi values. House and Part L.

Passivhaus Certification Ready

We’re Passivhaus Certifiers ourselves which means your details will be ‘oven-ready’ for PHPP and designed to glide through certification.


Precision Across Every Build Method

We have unrivalled knowledge through practical, hands-on experience. From SFS to timber frame, we understand the unique challenges, the tricky junctions, and detail-specific pitfalls.
