The 3 pillars of our Corporate Mission


Buildings account for a good third of global CO2 emissions. But in most cases, a lot of CO2 can be saved by simple measures. Our mission is to identify the levers on your assets that have the greatest impact. So that together we can really make a difference.

Value creation

ESG is increasingly impacting market performance, regulatory risk, and the financial returns of your assets. So if you approach ESG the right way, it becomes a tangible competitive advantage for you. We want to focus on those optimization measures that pay off in every way.


The data is there, but many times the consistent implementation of ESG fails due to complicated processes, psychological biases and stressful day-to-day business. That’s why we step up to make ESG implementation as simple as possible. With automation. And with fun.
