Arloid Automation

Arloid Automation

Crunchbase | Website | Twitter | Facebook | Linkedin

We build an AI solution that is trained to automatically change HVAC settings based on a calculated comfort index in real time. As a result, it leads to less energy consumption while keeping an optimal level of comfort.

Our solution complements very well to existing Building Management Systems and advanced data analytics tools/platforms. We are working with existing HVAC infrastructure of the building and don’t require an installation of additional hardware devices.

Overall, our approach allows fast (specific) building simulation, faster building integration process, shorter time to first money saved from energy optimisation and a possibility to create microclimates within one building for better comfort at reduced energy consumption.. .

Domatic empowers builders to create intelligent, sustainable buildings faster and at lower-cost than ever before. Domatic is a better way to power a building that significantly reduces the need for hard-to-find skilled labor and code inspections while making the resulting buildings more sustainable and efficient.

Our system combines a low-voltage DC approach to wiring with a data network on the same wires. All elements on the Domatic system are connected and intelligent and, because low-voltage isn’t subject to stringent building codes, installation is significantly faster and cheaper than existing high-voltage systems.

Jim was CTO, Television, at Microsoft and built the Mediaroom platform (AT&T licensed it for U-Verse), VP for the Digital Home Group at Intel. The team’s background in hardware, software, networking, and machine learning make Domatic an ideal product for us.

We’re very excited to bring Domatic to the world.. .
