We work as an extension of your team — providing clear, standards-aligned analysis so architects, façade engineers and contractors can progress design and approvals with confidence.
Small changes in geometry, materials or boundary conditions can influence U-values, Ψ-values and surface temperatures — with implications for compliance, comfort and durability.
Thermal performance is often assessed while designs are still evolving, under time pressure, and within a complex regulatory environment.
If performance is not evaluated accurately, projects may face additional design iterations, queries from stakeholders or delays in approvals.
We provide focused, standards-aligned thermal analysis with fast, responsive support — replying within 24h and helping you resolve iterative design issues quickly.
From first enquiry to final report in four clear steps.
Share drawings, build-ups and performance targets for the details you need assessed.
Get a clear quotation and analysis plan, aligned with the required standards.
Follow each unit of work in real time via our shared project board.
Download clearly documented results, ready for submissions and design coordination.

We have carried out more than 1,000 thermal analyses across a broad range of individual façade interfaces.
Our team combines practical façade experience with a strong focus on thermal analysis as a dedicated service.
We understand how thermal decisions affect programme, coordination and documentation on both smaller contractor-led projects and larger schemes.
We use modern project management platforms, automation and consistent processes to deliver work efficiently and maintain quality.
Facade Units is run by engineers with a combined background in façade consulting, contracting and numerical analysis.
Magdalena is an engineering and delivery specialist with extensive experience coordinating façade and building-physics projects in the UK and internationally. She brings a strong background in technical consulting, project management, and workflow optimisation, ensuring clarity, precision, and reliability in every stage of delivery. Her expertise spans façade performance analysis, thermal modelling, regulatory compliance, and client-focused engineering support. Magdalena is passionate about efficient processes, clear communication, and driving high-quality outcomes in fast-paced project environments.
Jacopo is a chartered façade engineering consultant with over 15 years of international experience across the UK, Europe, the US, Japan, and the Middle East. He holds a PhD in Façade Engineering from the University of Cambridge and an MSc in Structural Engineering from the University of Parma. His work focuses on advanced computational methods, engineering design automation, and building-physics performance, alongside traditional façade consultancy from concept to construction. Jacopo also lectures in Design of Structures at the University of Parma and has published in peer-reviewed journals and technical books.

Below is a selection of organisations and project teams we have supported with façade-related thermal assessments.
Thermal assessments carried out across a broad range of façade interfaces.
For selected 2D FEM details, subject to availability and project scope.
Experience with British, European and American methodologies and standards.
Although our background spans across all aspects of façade engineering, we focus exclusively on thermal assessments to provide depth, consistency and clarity in this specific area. As regulatory expectations around thermal performance continue to evolve, targeted and robust analysis has become increasingly important.
We offer on-demand expertise without the overhead of a hiring process. This gives our clients the flexibility to access project-specific thermal assessments when required — with efficient turnaround and minimal administrative effort.
We are a group of experienced engineers operating in the construction industry, specialising in façade engineering across a wide range of international projects. With backgrounds in both consultancy and contracting, we bring a practical and balanced perspective informed by established best practice.
Should you wish to meet us, drop us an email or fill out the contact form — we’d be happy to arrange a short introductory call.
We manage delivery on a per-unit basis, where each unit corresponds to a single output — such as a 2D analysis, 3D FEM model, or thermal shock simulation for one build-up configuration, for instance. Each unit type has a typical turnaround time, which we confirm at quotation stage. A 2D analysis takes on average one working day.
We use Notion to track progress, manage deliverables, and coordinate workflows efficiently. Our clients can also be granted access for up-to-date visibility on project status, if desired, along with the traditional email exchange.
Yes — all outputs are prepared in accordance with applicable industry standards, including BS EN ISO 6946, ISO 10211, and BR 497 where relevant. Methodologies are selected to suit project-specific requirements and regulatory context. For example, thermal bridging assessments for residential schemes in the UK are SAP-aligned and developed in accordance with Approved Document L, the SAP specification, and BR 497.
Yes — we carry PII coverage worldwide, excluding the US and Canada. A copy of the PII Certificate can be provided upon request.
We accept digital drawings in standard CAD formats (.dwg, .dxf) and vector-based PDFs that can be directly imported into CAD software. Please note that processing PDFs may extend lead times.
Drawings should follow industry best practice, including:
- Use of layers to separate elements (e.g. structural, thermal, fixings).
- Closed polylines for all objects (e.g. aluminium profiles), not disjointed lines.
- Use of blocks for repetitive elements.
- Clear dimensions, annotations, and correct scale.
- No overlapping or redundant geometry.
Drawings should contain all information necessary to carry out the thermal analysis without requiring us to interpret or modify the design. Vector-based PDFs should be clean, legible, and suitable for direct import into CAD software without quality loss. While we can address minor issues such as disjointed lines or missing hatches, we do not alter or complete incomplete designs. If any material data is missing, we may make reasonable assumptions solely for the purpose of analysis, and all such assumptions will be clearly documented in the final report.
Materials data
Thermal properties should be provided for all materials included in the analysis — such as thermal conductivity, emissivity, and centre-pane U-values for glazing or insulated components. Alternatively, relevant datasheets must be supplied to allow us to accurately determine these values.
Impact on lead times
If input files are incomplete or require significant adjustment, additional time may be needed, which can affect overall delivery times. We will advise on this as early as possible.
