Blog

Insights from engineering practice.

This is where we will publish articles on HVAC and building services design, renovation, heating system replacement and cost efficiency — technical, with no product advertising.

The first articles will be published from September 2026.

Planned topics

What we are working on.

A preview of the topics for the first articles — order and scope may still change.

Existing buildings

Replacing heat generators in existing buildings

How system choice, flow temperature and available space interact — and which groundwork should be in place before the decision.

Cost

Deriving rough cost estimates transparently

Which assumptions belong in a cost estimate, and how clients can review one.

Design

Model-based tendering

What a consistent software environment means for quantities, design stages and comparing bids.

Operation

Life cycle cost instead of investment only

Maintenance, accessibility and energy over decades — and why they shape the choice of variant early on.

Can your question not wait?

Until the first articles appear, we are happy to answer your questions directly — we respond to project enquiries within 72 hours.
