Best of all, our technology has a minuscule carbon footprint compared to solar installations, equipment and building retrofits, or new construction projects, and is more affordable to install, configure, and manage than any comparable building automation system on the market today.

The secret is our vertically integrated and IoT-based wireless solution, which brings together hardware and software not just to analyse building performance, but to control and optimize any existing HVAC equipment and systems. Every 60 seconds building data and projections are analyzed by sophisticated algorithms in our cloud and micro-adjustments are made if needed. Each 75F customer site receives roughly 150,000 individual decisions each day to ensure optimal comfort, indoor air quality, and energy and cost savings. We are headquartered in the US, with offices across India, Singapore, and the Middle East
