Public buildings: open standards and documentation for acceptance
A school, council office, sports or cultural facility: the system must be possible to describe in a tender, accept and service years later. That is why we work with open standards and hand over full as-built documentation.
- „How do we describe automation in a tender without naming one brand?”
- „After a few years nobody knows how the installation works.”
- „We need to check whether the building requires a building automation system (BACS).”
Three layers
What do we combine into one system?
We design the electrical installation, automation and network together, so they work as one system with one party responsible.
Electrical
- Installations and distribution boards
- Protected circuits for automation and the network
Automation and security
- Lighting in the DALI standard
- Heating and ventilation – integration via Modbus
- KNX where the tender requires it
IT
- Network divided into VLANs
- Wi-Fi
- Cabling measurements
Construction stages
Ideally at the stage of describing the subject of the tender
It costs least at the design or shell stage. The later it gets, the more changes to a wired installation require chasing walls; wireless systems are the exception.
| Stage | What we do then | Cost of changes |
|---|---|---|
| Design | Guidelines for the design: distribution board, routes, external shading | lowest |
| Open shell | Conduits and penetrations without thermal bridges, Power supply for blind boxes | low |
| Closed shell (windows installed) | Blind and shading drives, Window contacts, Airtight installation penetrations | low |
| Before plastering | Cabling, Measurements, Presence at the airtightness test | medium |
| After plastering | Wireless systems (Loxone, Ampio, Somfy), Minimal wall chasing | higherapplies to wired installations; with a wireless system the cost does not increase |
| Renovation / retrofit | Assessment of the existing installation and distribution board, Wireless systems where there are no cables | higherapplies to wired installations; with a wireless system the cost does not increase |
Who does the work
What do partners do?
Some work requires other qualifications. For each of them we state clearly whether we coordinate it or recommend a partner.
We coordinate – done by a partner
Carried out by: partner carrying out airtightness tests
Airtightness test (blower door)
After the airtight layer and before finishing; we are on site and seal our own penetrations.
We recommend a partner
Carried out by: qualified energy auditor
Energy audit
Assessment of the building and improvement options; we adapt the automation to the results.
We coordinate – done by a partner
Carried out by: partner carrying out insulation and window work
Thermal retrofit
Insulation and windows are done by a partner; we do the electrical installation, automation and shading control.
FAQ
Frequently asked questions
Does a commercial building need a building automation system (BACS)?
It depends on the output of the heating or cooling installation. We check this for the specific building.
