About

Founded in 1994, we’ve been doing great things for over 25 years.

3fficient is an international award winning clean-tech utility cost savings company. We work with building owners and their tenants to redirect incentives, energy, water and other cost savings back into their business, people and brand.  So far, we’ve saved our customers over $1 Billion (and counting).

We are a diverse team of engineers, building scientists, project managers, integrators and finance experts. Our bundling of innovative clean technologies and incentives far exceed results from a status quo approach. We have helped hundreds of businesses and institutions become more efficient, productive and sustainable while significantly decarbonizing their footprint. 

In recent years, we have helped develop smart AI for buildings, fully wireless building controls that dramatically reduce the costs of automation and remodeling, invisible window insulation that is 300% better than plastic tints, passive insulation materials that flatten power demand while saving energy and smart urban furniture that makes schools safer and cities more resilient.

We are excited about the future for our customers, our partners and our business as the world recognizes how essentially important and valuable efficiency and energy security truly is.
