Our mission

We make buildings more efficient

Buildings consume a lot of energy.  They account for 32% of global energy use and one-quarter of human-caused CO2 emissions.  By 2050, 66% of the world’s population will live in cities, contributing to an ever-growing energy footprint of the global building stock.  Yet, efficient energy use with existing technology could reduce building greenhouse gas emissions by 83% from our current trajectory.  We believe the best way to achieve this outcome is to empower building owners and property managers with the ability to make energy-smart decisions that reduce their energy usage and increase their operating margins.

GreyJay Energy is an energy intelligence company for commercial office and apartment buildings. We use utility energy data to monitor and benchmark building energy use for owners and operators. We monitor energy data for every building in a portfolio and recommend options to lower energy use, reduce maintenance costs, and increase net operating income.
