Homes that save money… and the environment!

With each year that passes, we broaden the opportunities for property owners and/or apartment owners to influence energy consumption and comfort. We offer a range of options to apartment owners wanting to influence and change their energy consumption through individual metering and charging. Sometimes, however, the same benefits can be achieved by controlling your energy use, servicing and comfort through our cloud service, which gives you complete control. We draw on our experience to find you management and optimisation solutions that meets your specific needs.

You get control via energy reports, maintenance planning, alarm reports, technical documentation, inspection reports and much more, all in one place. Arrigo delivers numerous energy and cost savings and efficient facility management.
