People-Aware Climate Control

Crowded rooms don't have to be stuffy

Envairo increases office comfort by adapting cooling and ventilation based on room occupancy. Plenty of fresh air for everyone, and no more sweaters in the summer.

Save money when spaces are empty

Envairo reduces ventilation and cooling to save energy when occupancy is low.

Healthier, more productive offices

Not getting enough fresh air makes people drowsy, hurts focus and can compromise health. It's also hard to work if you're freezing or sweltering.

Energy savings with optimized control

Spaces can save 10-20% on their total energy costs and enjoy a payback of less than 1 year. Envairo works with or without an existing building management system.
