We decarbonize the built environment through profitable investments for Commercial Real Estate

At Carbon Lighthouse, we specialize in creating high-return investments for CRE firms, funds and REITs. If you own a typical 100k sq. ft. building, a one-time investment of $30k in building improvements can generate $20k to $40k in new rent and $30k+ in tenant savings. It's a low-cost, high-impact way to boost your bottom line.

We launched in 2010, are in 1,800+ buildings across the United States, and our major MOB customers include Welltower, Ventas, DOC REIT, and more.

We make decarbonization so easy and profitable that building owners do it everywhere.

We've used them everywhere we can

"Carbon Lighthouse predicted solid return on cost and environmental goals, so I did extensive due diligence on the technology and the company, and I'm excited to say CL performed well and returns exceeded what was promised. After capitalizing the perpetual savings, we achieved a 3x return on equity. Where else can we get that in the current market?"

You’ve located the “needle in the haystack" for us

"This is really impressive. Other platforms that we use provide us with an alert that we’re outside of normal usage but... that’s it? Our engineers don’t even know where to begin to look. Your alerts drive our engineers to the exact spot that is causing the additional energy consumption.
