Building Energy Certification Platform
How we studied a specialist engineering workflow and translated it into a reliable, maintainable platform for energy auditors.

Automatically generated building energy certificate from structured project data.
Challenge
From fragmented spreadsheets to a structured engineering workflow.
A certified energy auditor relied on interconnected Excel workbooks, Word templates, government-issued forms, and legacy desktop software to complete building energy assessments.
Each project required hundreds of measurements, technical inputs, material properties, system parameters, and engineering calculations before a final certificate could be produced.
The process worked, but it was manual, repetitive, difficult to maintain, and vulnerable to inconsistencies whenever data had to be copied between spreadsheets and documents.
Before designing the platform, we had to understand how the auditor actually worked: where data entered the process, how the calculations related to one another, which outputs were mandatory, and where professional judgment still mattered.
Before
Manual spreadsheet workflow
- Interconnected Excel files with hidden formulas
- Manual copying into Word and certificate templates
- Legacy desktop software used for regulatory output
- Repeated data entry across multiple documents
- Calculation changes hard to verify and maintain
After
Centralized certification platform
- Structured project database for each building
- Application-level engineering calculations
- Reusable workflows for building systems and measures
- Automated export and document preparation
- Configurable parameters for future updates
Solution
We learned the auditing process, then modeled it as software.
Rather than simply recreating spreadsheets in a browser, the platform captures the full certification lifecycle as a structured workflow.

Legacy process
Years of domain expertise were trapped inside spreadsheets.
The original workflow contained deeply specialized engineering calculations, regulatory assumptions, reusable templates, and auditor-specific methodology. The project required understanding that knowledge before translating it into software.

Platform
A web platform for large, technical engineering datasets.
The application organizes hundreds of parameters into clear sections, allowing auditors to manage normalized and actual building states, evaluate energy-saving measures, and export structured results.
Scope
The platform captured the structure of real buildings.
Engineering
Turning expert methodology into maintainable software.
Research before implementation
The work began with the existing process: tracing how data moved across surveys, spreadsheets, calculations, templates, and regulatory outputs. That understanding shaped the product model and the implementation.
Engineering knowledge translated into software
Existing calculations were distributed across Excel formulas, engineering standards, and regulatory documents. We transformed that domain knowledge into maintainable application logic while preserving calculation accuracy.
Complex domain modeling
The platform models buildings as interconnected systems instead of disconnected spreadsheets, helping auditors maintain consistency across measurements, materials, systems, and energy-saving measures.
Structured workflow for large datasets
Energy audits require hundreds of inputs. We organized them into clear sections so auditors could navigate complex building data without losing context.
Document automation
Project data can be reused across the reporting workflow to populate standardized documents and certificates required by the relevant authorities.
Product
Secure access for managing multiple certification projects.
The application introduced standard product capabilities including authentication, project storage, editable datasets, exports, and administrator-managed calculation parameters.

Outcome
A repeatable workflow for producing energy certification documents.
The platform replaced fragmented files with a centralized application that supports the auditor from initial project setup through calculation and certificate preparation.
Centralized project data in a secure web platform
Replaced spreadsheet-driven calculations with maintainable application logic
Reduced repetitive manual work across reports and templates
Standardized engineering calculations across projects
Automated preparation of government-required documentation
Created a foundation that can evolve with future regulatory changes
Have a process generic software cannot capture?
Klamiq studies complex workflows and translates the underlying knowledge into maintainable, scalable systems, using automation and AI where they genuinely improve the outcome.
