Easier, faster WEii certification and benchmarking 

Healthy Workers introduces an automated process that makes WEii certification and benchmarking easier and faster. The WEii certificate measures actual energy consumption, demonstrates the impact of sustainability investments, and enables effective benchmarking.

The first WEii license holder to fully automate the process using the WEii API

Healthy Workers is the first license holder to fully automate the process using the WEii API. By combining automated data collection with the precision of the WEii API, we set a new standard for innovation and efficiency.

We collect all necessary data, act as your central point of contact, and deliver reliable WEii scores. This reduces the administrative burden and eliminates the need for external agencies.

Beyond certification, we instantly identify opportunities for improvement, helping you boost your WEii score year after year.
