Bring new life into aging buildings.


All too often, owners have been told that making their buildings or processes green or highly efficient costs more.  Well that’s just not true.  For decades, we have successfully retrofitted all types of commercial and industrial buildings making them super efficient and highly sustainable.  How so?  Experience, holistic approach and proprietary clean-tech innovations.  Well, while we can’t reveal all our secrets, we can tell you we essentially do more with less. We literally have hundreds of energy efficiency measures, smart design improvements and architectural upgrades to make your operations more efficient, more productive and more sustainable, often without any capital needs on your part!

As buildings age, their systems, equipment and processes start leaking money.  But, it doesn’t have to stay that way and your operations do not have to be in bad shape to warrant improvements.  3fficient experts have engineered hundreds of high performance, green building upgrades, saving our clients over $1 Billion in the process.  Whether you have a newly minted LEED building or an old historic landmark, we have the practical expertise and technology innovations that are guaranteed to save your bottom line.

  • You saved us $200,000/yr. At 5% pre-tax profit margin, that's the same as generating $4,000,000 in new revenue every year! It also increases our company valuation by $1,000,000. Thank you so much!
