Carbon Lighthouse raises $27 million to improve building efficiency



San Francisco-based Carbon Lighthouse works with building owners to make energy, lighting and HVAC equipment “smarter” with monitors and sensors.

Buildings are an important target for energy efficiency improvements because they account for 30% of global carbon emissions and up to 70% of energy use in cities.

Carbon Lighthouse has worked on energy efficiency solutions for 500 buildings in the US.

The $27 million funding round was backed by JCI Ventures, SV Tech Ventures and Radicle Impact Partners. Ulupono Initiative, a Hawaii-based impact investing firm started by Pierre Omidyar, invested $3 million, Pacific Business News reports.

Carbon Lighthouse says Hawaii is a promising market: high electricity prices mean returns on the company’s technology can be three times higher than on the US mainland.
