GLM (Z.ai) isn't on our list for building management & installations. It's usable for general work, but first look at the options we recommend for building management & installations.

GLM (Z.ai) carries a concrete GDPR concern. Parent company Zhipu (Beijing) falls under Chinese data and security legislation, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before deploying it in building management & installations.

Confidentiality and GDPR

GDPR: Caution

Keep two things in view at once. First, privacy: occupancy, badge and booking data can often be traced back to individual employees. Measure at zone or room level, not per person, and involve the works council when introducing it, a system that records staff presence falls under article 27 of the Dutch Works Councils Act (WOR) on staff monitoring systems. Second, security: an AI layer that is allowed to control your BMS becomes part of your operational technology. Never expose that connection unsecured to the internet, work with read-only access until you trust the behaviour, and record who can intervene if the control goes wrong, in care buildings, laboratories and server rooms, a wrong setpoint can cause immediate damage. If you fall under NIS2, there are explicit requirements for supplier management and incident reporting. Also agree a data processing agreement and EU hosting with every supplier, and check energy-saving claims against your own meter data rather than the brochure.

The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.

Questions about GLM (Z.ai) for building management & installations

May I put confidential data into GLM (Z.ai)?

Measure at zone or room level, not per person, and involve the works council when introducing it, a system that registers staff presence falls under article 27 of the Dutch Works Councils Act (WOR) (staff monitoring systems). Second, security: an AI layer that is allowed to control your building management system becomes part of your operational technology. Never connect that link to the internet unsecured, work with read-only access for as long as you do not yet trust its behaviour, and record who can intervene if the control goes off course. In care buildings, laboratories and server rooms, a wrong setpoint can cause direct damage. If you fall under NIS2, explicit requirements apply to supplier management and incident reporting. Furthermore, record a data processing agreement and EU hosting with every supplier, and check energy-saving claims against your own meter data rather than the brochure. The international service Z.ai runs via JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore.
