m4chanical HVACComing soon

Mechanical building services calculations, linked in one project.

m4chanical HVAC is being developed as a calculation suite that combines fresh air, heat loss, cooling load, duct and pipe sizing, fans and acoustics in one project. Change one input and every linked calculation and the equipment list update. The product is not available yet.

Who it is for

  • Building services design engineers
  • Design and consulting offices
  • Contractor technical offices

The problem

  • When calculations live in separate files, a change to one input (city, indoor conditions, rooms) has to be carried over by hand, and revisions drift apart.
  • Points that exceed velocity, pressure or noise limits are only found by careful checking.
  • The equipment list (BoQ) is compiled by hand from the calculations and goes out of date.

Frequently asked questions

Will calculations work like a spreadsheet?

Yes, everything is linked: change the city or indoor conditions and heat loss, cooling load and equipment selections update together. The difference is that projects are stored in your account and results are summarised on one screen.

When will the HVAC product be available?

We are not sharing a date. Fill in the form and we will write to you when the status changes.

Can I get HVAC support today?

Describe your need; if it can be covered as an engineering service, we will clarify scope in a call.
